Topics:

Purpose of this guide Audience Prerequisites, limitations, and resources Architecture overview

Purpose of this guide

This installation guide is intended as a supplement to the DD Operating System Administration Guide, which includes content applicable to all DD systems, including upgrading the DDVE software and using the DD System Manager to monitor DD systems for errors, disk space, and service events.

This guide contains content specific to deploying DD Virtual Edition (DDVE) on Amazon Web Services. Use this guide in conjunction with the DD Operating System Administration Guide and applicable AWS documentation.

See AWS Cloud Formation documentation for more information.

Audience This document is intended for data protection and storage administrators who want to use Amazon Web Services to back up DD Virtual Edition (DDVE) content. Users should have knowledge of the following technology:

AWS Management Console AWS services, such as AWS IAM, AWS CloudFormation, VPC, AWS security group, and route tables Amazon EC2, EBS, and S3 services

Prerequisites, limitations, and resources Review the general requirements for deploying DDVE on Amazon Web Services (AWS).

Create an AWS account

To deploy DDVE on AWS, you must have an AWS account. To set up an account, go to https://aws.amazon.com/getting- started/.

Identity and access management

AWS recommends that you create an IAM user or role for authenticating with AWS and never use root credentials to deploy the CloudFormation template. The IAM user must be allowed to perform AWS CloudFormation actions. The EC2 instance must be granted the IAM role to provide permissions to S3 storage.

The following links provide more information about AWS best practices:

Architecture overview DDVE is a virtual deduplication appliance that provides data protection for entry, enterprise, and service provider environments.

The following diagram represents the architecture of the DDVE on AWS solution.

8 Getting Started

Figure 1. Dell EMC Power Protect DD Virtual Edition (DDVE) on AWS

Legend:

1. To keep data traffic between DDVE and the S3 bucket within the AWS infrastructure, it is recommended that you create an S3 endpoint. The S3 endpoint keeps DDVE from depending on a NAT Gateway or Public IP address to access the S3 bucket.

2. To keep data transfers secure, it is recommended to use a VPN connection to replicate data from an on-premises host to DDVE in the cloud or the opposite way.

3. DDVE is categorized as a backend server. It must be kept in a private subnet with a private address. Never set a public IP address for DDVE.

4. It is recommended that you create the S3 bucket in the region where the DDVE instance is running. A separate bucket per each DDVE is required.

5. All DDVE instances must be secured with the appropriate security group entries.

Typically SSH (Port 22) or HTTPS (Port 443) is used for DDVE inbound access.

HTTPS (443) must be allowed for outbound S3 bucket access for DDVE.

TCP ports 2049 and 2051 are used for DD Boost and replication purposes.

See the DDVE documentation for more information and for a complete list of ports.

Availability Zones

DDVE is deployed within a single Availability Zone (AZ). It can be deployed within additional AZs to provide region redundancy using DD replication capabilities. The solution can also be deployed in alternative regions to provide further redundancy as needed.

Introducing DDVE This chapter includes the following topics:

Topics:

Introducing DDVE DDVE cloud features

Introducing DDVE DD Virtual Edition (DDVE) is a software-only protection storage appliance: a virtual deduplication appliance that provides data protection for entry, enterprise and service provider environments. Like any DD system, DDVE is always paired with backup software.

DDVE runs the DD Operating System (DDOS), and includes the DD System Manager graphical user interface (GUI) and the DDOS command line interface (CLI) for performing system operations.

DDVE includes the following features:

High-speed, variable length deduplication for a 10 to 30 times reduction in storage requirements Unparalleled data integrity to ensure reliable recovery, and seamless integration with leading backup and archiving

applications DD Boost to speed backups by 50 percent DD Encryption for enhanced security of data DD Replicator for network efficient replication that enables faster time-to-DR readiness

DDVE runs on two types of platforms:

On premises, DDVE supports VMware, Hyper-V, KVM, and VxRail. In the cloud, DDVE also runs in the Amazon Web Services (AWS) (cloud and gov cloud), Azure (cloud and gov cloud),

VMware Cloud (VMC) on AWS cloud platforms, and Google Cloud Platform (GCP).

For more information about the features and capabilities of DD systems (both physical and virtual), see the DD Operating System Administration Guide.

DDVE cloud features DDVE provides the capabilities of a cloud DD system using the following resource configuration sizes:

Table 2. DDVE on AWS resource configuration size

Introducing DDVE 11

Deploying DDVE This chapter includes the following topics:

Topics:

Preparing your environment to deploy DDVE on AWS Deploying DDVE in AWS

Preparing your environment to deploy DDVE on AWS While DDVE is running in AWS cloud, customers can backup and restore their operational data from an S3 object store.

Observe these requirements:

Storage tier - DDVE on AWS supports Active Tier (Cloud Tier is not supported). Storage class - AWS provides multiple storage classes (Standard S3, Standard-IA, and so on). Standard S3 offers high

durability, availability, and performance for frequently accessed data. DDVE on AWS supports Standard S3.

The following sections provide general guidelines to deploy, configure, and run DDVE on AWS with Active Tier on S3 storage.

The high-level steps are as follows:

1. Configure the network environment.

For secure access to the DDVE, follow the best practices recommended by AWS for your VPC architecture. Configure the following components:

VPC Subnet Route tables Security groups Network access control list

NOTE: Make sure to allow DDVE inbound and outbound access to S3. If you are unsure which S3 IP addresses to

allow, refer to the route table entry for S3 endpoint.

VPC Gateway endpoint for connectivity to S3 NOTE: DDVE supports standard endpoint format. If you configure firewall rules for endpoints, requests that map to

the standard endpoints (*.s3. .amazonaws.com) must be allowed.

Networking Best Practices for DDVE in the Cloud on page 54 provides more information. 2. Create an S3 bucket. 3. Configure role-based access to the AWS object store. 4. For secure login to DDVE, create an EC2 key access pair. See Amazon EC2 Key Pairs for instructions.

Create an S3 bucket

About this task

Create a bucket in S3 and make note of the bucket name. The bucket name is used in the IAM policy template to get access to the bucket. It is also used to create the object store profile on the DDVE.

Steps

1. Log in to the AWS console. Select Services > S3.

2. Click Create bucket and enter a bucket name and region for your installation.

3

12 Deploying DDVE

NOTE: Observe these requirements when creating a bucket for DDVE use:

To access an S3 bucket, AWS recommends using hosted-style URLs (where domain name includes the bucket name) instead of path-style URLs. For hosted-style URLs to work, do not use dots (".") in the bucket name.

Create the bucket in the same region as the DDVE instance. Provide a bucket name that is no longer than 48 characters. Do not enable bucket versioning for the bucket that is associated with the DDVE for these reasons:

Versioning adds to storage costs because older versions of the objects are retained despite running the DDVE garbage collection process.

Enabling versioning can also cause potential performance issues.

3. When required fields are completed, click the Create Bucket button. See this example:

NOTE: Do not set up life-cycle rules for this bucket. Life-cycle rules could cause loss of critical data from the object

store.

Deploying DDVE 13

Set up role-based access to the AWS object store

Object store in AWS uses role-based access for S3 access. To access the S3 bucket, create and attach the Identity and Access Management (IAM) role to DDVE.

Prerequisites

To create the IAM role and the policy that is associated with the role, the AWS user must have the necessary IAM privileges. The following IAM privileges and actions are required to create and attach the IAM role:

"iam:AddRoleToInstanceProfile", "iam:AttachRolePolicy", "iam:CreateRole", "iam:DeleteRole", "iam:DeleteRolePolicy", "iam:DetachRolePolicy", "iam:GetRole", "iam:GetRolePolicy", "iam:ListRolePolicies", "iam:ListRoles", "iam:PassRole", "iam:RemoveRoleFromInstanceProfile", "iam:UpdateRolePolicy", "iam:CreateInstanceProfile", "iam:PutRolePolicy", "iam:DeleteInstanceProfile"

About this task

When the role is attached to DDVE, the S3 object store credentials are automatically fetched. The AWS infrastructure periodically rotates the access credentials. The DDVE automatically fetches the new credentials before the old credentials expire.

Steps

1. Create the policy to attach with the IAM role:

a. Sign in to the AWS Management Console and open the IAM Service Console. b. In the navigation pane of the IAM console, select Policies > Create policy. c. Do one of the following:

Create a policy for AWS Standard Cloud:

In the Create policy web page, select the JSON tab. Replace the text under the JSON tab with the following content. Replace my-bucket-name with the name of the bucket that you created in Create an S3 bucket on page 12.

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "s3:ListBucket", "s3:GetObject", "s3:PutObject", "s3:DeleteObject" ], "Resource": [ "arn:aws:s3:::my-bucket-name", "arn:aws:s3:::my-bucket-name/*" ] } ] }

Create a policy for AWS Gov Cloud:

In the Create policy web page, select the JSON tab. Replace the text under the JSON tab with the following content. Replace my-bucket-name with the name of the bucket that you created in Create an S3 bucket on page 12. For the resource tag below, use arn:aws-us-gov:s3:::my-bucket-name for AWS Gov clouds.

14 Deploying DDVE

{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "s3:ListBucket", "s3:GetObject", "s3:PutObject", "s3:DeleteObject" ], "Resource": [ "arn:aws-us-gov:s3:::my-bucket-name", "arn:aws-us-gov:s3:::my-bucket-name/*" ] } ] }

d. Verify this information, and then click Review policy. e. Provide a name and description for the policy, and click Create policy.

NOTE: Make a note of the policy name. It will be used to attach the policy to the role in the next step.

2. Create the role for S3 bucket access:

a. In the navigation pane of the IAM console, select Roles > Create role. b. On the Create role page:

i. For Select type of trusted entity, select AWS service. ii. For Choose the service that will use this role, select EC2, and then click Next Permissions.

c. On the Attach permissions policies page, select the policy that you created in the previous step. Select Next Tags to create a tag for the role.

Deploying DDVE 15

Figure 2. Creating a role

d. Click Next:Review. In the Review section, provide a name for the role and click Create role.

Next steps

You must attach the role to the DDVE instance before it can be configured. This task can be done during or after deployment.

Deploying DDVE in AWS You can deploy DDVE on AWS in two ways.

About this task

Methods of deployment in AWS: Cloud Formation Template (CFT) from AWS marketplace DDVE Manual Deployment from AWS console

Dell EMC strongly recommends using the CFT method because it automatically creates and attaches NVRAM and metadata disks in the correct order according to Storage best practices.

Deploying DDVE using a Cloud Formation Template

This method is recommended.

Steps

1. Go to the appropriate Website: For deployment in AWS standard cloud, use https://aws.amazon.com/marketplace. For deployment in AWS Gov cloud, use https://aws.amazon.com/mp/govcloud/.

2. Search for PowerProtect DD Virtual.

3. Select Dell EMC PowerProtect DD Virtual Edition (DDVE) and click Continue to Subscribe.

NOTE: Your screen might be different than shown in the following figure.

96 TB M5.4xlarge 16 64 10 x 1 TiB

256 TB M5.8xlarge 32 128 13 x 2 TiB

Override default metadata disks You can choose to override the default number of metadata disks by selecting a value from 1-24. The maximum number of metadata disks that can be attached to a DDVE instance in AWS is 24.

NOTE: Only the number of metadata disks can be overridden. The size of individual disks cannot be changed.

18 Deploying DDVE

DDVE name tag IAM Role for S3 accessType in the correct IAM role to be attached to the DDVE. Key pairSelect an existing key pair from the drop-down list. Subnet ID Security Groups

NOTE: The values in this figure are examples only. Replace them with values from your setup.

9. Continue stack configuration as needed. Click Next.

10. Review the stack configuration and click Create Stack.

11. Check the status of the stack you create on the ddve-stack-test page.

12. When the stack creation is complete, go to the EC2 instances and select the region to deploy the DDVE. Use the DDVE name tag from step 8 and verify that the corresponding EC2 instance is running.

NOTE: Avoid disabling or modifying the primary interface settings. The primary interface in cloud deployments has

the default gateway setting and is the only interface with which the DDVE can connect to the metadata server. The

metadata server is critical for DDVE operation.

Deploying DDVE 19

Deploying DDVE manually from the AWS console

This is an alternate approach for deployment.

Steps

1. Login to AWS console and navigate to the EC2 instances link.

2. Under the EC2 instances tab, select Private Images. Select the AMI image from the region in which you wish to deploy DDVE, and then click Launch.

3. Select the instance type from the three supported instance types. Click Configure Instance Details. For more details, refer to Storage best practices.

4. Select the VPC and subnet in which to deploy DDVE, and select the IAM role that you created in the previous section. Selecting the role during deployment automatically attaches it to this DDVE instance. If you did not previously create the VPC, subnet, or the IAM role, you can create them in this step. When you are done, click Add Storage.

20 Deploying DDVE

5. Add the NVRAM disk and metadata disks as shown below. Then click Add Tags.

a. Add a 10 GiB NVRAM disk (highlighted in red) according to the following configuration table. b. Add the metadata disks (highlighted in green) according to the following configuration table.

NOTE: Add the NVRAM disk before adding the metadata disks. Adding them in a different order causes an unsupported

hardware configuration error. Also, ensure that the EBS volume type is GP3, IOPS is 3000, and throughput is 125 MB/s

for all disks.

Table 3. Recommended configuration

Instance Type Number of metadata disks Size of each metadata disk Object store capacity

M5.xlarge 2 1 TiB 16 TB

M5.2xlarge 4 1 TiB 32 TB

M5.4xlarge 10 1 TiB 96 TB

M5.8xlarge 13 2 TiB 256 TB

Deploying DDVE 21

NOTE: By default, the recommended metadata storage is 10% of the total capacity. This recommendation is based on

a 10x deduplication ratio and a 2x compression ratio. For workloads with higher deduplication ratios, you can add more

metadata disks.

6. Add the tags as shown in the following figure, and then click Configure Security Groups.

Adding tags enables you to easily search for volumes and instances.

7. Select from an existing security group. If you haven't created one previously, you can create it now. Click Review and Launch.

8. Review the configuration details, and then click Launch.

9. Select a key pair value or create a new key pair value for this instance, and then click Launch Instance.

22 Deploying DDVE

10. Click View instances to navigate to the EC2 instance tab. Search for the tag you created in step 6.

NOTE: Avoid disabling or modifying the primary interface settings. The primary interface in cloud deployments has

the default gateway setting and is the only interface with which the DDVE can connect to the metadata server. The

metadata server is critical for DDVE operation.

Adding more metadata disks for the DDVE instance

If required, more metadata disks can be added to the DDVE instance from the AWS console.

Prerequisites

AWS DDVE instances support adding only up to 24 metadata disks. If you reach the limit for adding metadata disks, you can choose to expand the existing metadata disks. See Expand metadata storage on page 26 for details. If you are using GP2, migrate the existing GP2 disks to GP3. For details, see Storage best practices on page 48.

Deploying DDVE 23

Steps

1. Log in to the AWS console.

2. Select EC2 dashboard under services. Navigate to the Elastic Block Store pane and click Volumes.

3. Provide the following details. Then click Create Volume.

Volume Type: Select GP3. Size (GiB): Select 1024 for 16/32/96 TB DDVE instance and 2048 for 256 TB DDVE instance. IOPS: Set 3000 Throughput MB/s: Set 125 Availability Zone (AZ): Choose the same AZ in which the DDVE instance is deployed. Name Tag: Add a name tag for the volume to filter it in searches.

Leave Snapshot ID blank.

4. In the Volumes tab, enter the name tag (created in previous step) for the volume. Select the volume, click Actions, and select Attach Volume.

24 Deploying DDVE

5. In the attach volume window, enter the instance ID and device name:

Instance: Enter the name/instance ID of the DDVE instance, and select the correct instance from the list of instance options.

Device: Based on the instance, a default device name is automatically populated in this field. The device names for existing volumes on this instance can be /dev/sd* or /dev/xvd*. Ensure that the new volume being attached follows the device naming convention for other metadata disks on this instance.

NOTE: You can check the device names for an instance by selecting an instance in the EC2 dashboard and viewing the

block device names for its EBS volumes:

Deploying DDVE 25

6. To create and attach additional metadata disks to the DDVE instance, repeat steps 2 on page 24 to 5 on page 25.

7. To configure the metadata storage using CLI or DDSM, log in to the DDVE instance.

Using CLI: Run the disk show hardware command to verify that the new metadata disk or disks are successfully added to the

DDVE instance. Run the storage add dev command to add the new metadata disk or disks to the active tier.

Run the filesys expand to make the newly added metadata disk or disks available to the filesystem.

Using DDSM:

Alternatively, you can configure the storage using DDSM. Click Hardware > Storage > Configure Storage.

NOTE: Do not manually configure spindle groups. Spindle group configuration occurs automatically.

Expand metadata storage

Expand metadata storage by increasing the size of existing metadata disks.

Prerequisites

It is recommended that you expand metadata storage by adding new metadata disks. When the total number of metadata disks reaches its limit, you can expand metadata storage by increasing the size of existing metadata disks.

Before expanding metadata storage, disable the file system. You cannot expand the first metadata disk. When expanding the size of an existing metadata disk, it is recommended to expand it in 1 TiB increments. Shrinking the metadata disk is not supported.

Steps

1. Shut down the DDVE instance by using the system system poweroff command from the CLI.

2. Log in to the AWS web console.

a. From the Volumes tab, select the metadata disk that you want to expand.

NOTE: The first metadata disk is not available for expansion.

b. Click Actions > Modify Volume. c. Change the size of the metadata disk (for example, from 1024 TiB to 2048 TiB), and click Modify.

3. To increase the size of other metadata disks, if required, repeat step 2 on page 26.

4. From the AWS web console, select the DDVE and start it.

5. Disable the file system with the filesys disable command.

6. Expand metadata storage with the filesys expand command.

7. Enable the file system by using the filesys enable command.

8. To confirm the metadata storage expansion, use the filesys show space tier active local-metadata command.

By default, DDVE uses Amazon Time Sync Service for time synchronization through a chrony client. DDVE does not require Internet access or configuration of security group rules to use this time synchronization service. Dell EMC recommends using the Amazon Time Sync Service.

Method 2 - Configuring NTP server (not recommended)

To override the default, you can configure an NTP server on the DDVE: a. Select Administration > Settings. b. Select More Tasks > Configure Time Settings. c. Under More Tasks, select NTP > Manually Configure and add the NTP servers as

0.amazon.pool.ntp.org.

NOTE: To switch to the default service (Amazon Time Sync), select Administration >

Settings > More Tasks > Configure Time Settings > Choose None.

Results

The DDVE configuration is complete.

Updating the configuration

If you modify the object-store profile or make other changes after the initial DDVE configuration, you will need to relaunch the configuration wizard.

3. Select Data Management > File System to view object store local metadata storage.

Using the CLI to configure the DDVE

You can log in through SSH to configure the DDVE using the command line interface (CLI). Authentication using EC2 key access pair and username and password are supported.

Steps

1. Log in to the DDVE instance to configure the system. The default login credentials for the DDVE instance are: Username: sysadmin AWS default password: Default sysadmin password is the EC2 instance-id for the DDVE.

# ssh sysadmin@ EMC DD Virtual Edition Password:

Welcome to Data Domain OS 7.2.0.5-xyz sysadmin@myddve0#

2. During the first login, users are prompted to accept the EULA and change the password.

3. The configuration wizard launches.

4. Follow the steps in the wizard to add elicenses and configure object store.

NOTE:

If an elicense file cannot be found in /ddr/var, the license can be pasted directly in the wizard.

The System Passphrase is required to encrypt the object store credentials. If file system encryption is enabled, the

System Passphrase is also used to encrypt keys.

For AWS, the profile creation requires that you import the Baltimore CyberTrust Root certificate to communicate

with the object store.

For AWS GovCloud, profile creation has an additional option to enable the FIPS endpoint.

Recovering DDVE with system headswap A system headswap recovers a DDVE instance from a head unit failure. The head unit is the DDVE root disk.

Prerequisites

System headswap between the same DDOS versions is recommended. When the same DDOS version is not available, system headswap can be done with a later DDOS version. The DDOS version compatibility rules are the same as the RPM upgrade.

Ensure that the vNVRAM disk and metadata disks from system A (original system) are available for attaching to the new instance B. If either the vNVRAM disk or any metadata disk is unavailable, use Recovering the DDVE instance on page 36.

A static IP address that is configured using DDVE interfaces (CLI or UI) is not recommended. If a static IP address is configured on the network interface in the original DDVE, the same configuration is restored on the new head. This scenario might cause a network disconnection.

Generally, instead of configuring a static IP address using DDVE interfaces, configure it in the cloud provider environment. The DDVE uses DHCP to obtain the static IP address that you configure in the cloud environment.

If you are already using a static IP address that is configured within DDVE, and a disconnection occurs after following these steps, power off the DDVE. Then add an additional network interface to the new DDVE, and login using the IP address of this interface. Finally, enable or reconfigure the primary network interface on the new head, preferably using DHCP.

About this task

Follow these steps only to recover DDVE with a head unit (root disk) failure.

Steps

1. Create instance B with Head Unit (root disk only) with the same instance type as instance A.

2. Attach the same role to instance B as that of instance A.

3. On instance A, make a note of the vNVRAM disk name (usually sdb). Use the same name when attaching the vNVRAM disk to instance B.

4. Detach the vNVRAM and metadata disks from the failed head unit.

34 Completing Initial DDVE Configuration

5. Attach the vNVRAM disk to instance B. While attaching the vNVRAM disk, ensure that the name of the disk on instance B is same as that on instance A.

NOTE: Ensure that the vNVRAM disk is attached before attaching the metadata disks.

6. Attach the metadata disks to instance B.

7. Set the system passphrase.

NOTE: Set the passphrase to match system A, otherwise, the headswap fails.

# system passphrase set Enter new passphrase: Re-enter new passphrase: Passphrases matched. The passphrase is set.

8. Before running the headswap command, ensure that system A is powered off. This step is required to detach the bucket from system A and make it available to be attached to system B.

9. Run system headswap.

NOTE: The system reboots during the headswap process.

# system headswap This command returns the system back to its prior operational conditions. The system will be rebooted before resuming normal operations. ** If system passphrase was set on the old head, you will need to do one of the following after headswap completes: - unlock the filesystem if you have encrypted data, or - set the system passphrase if you don't have encrypted data Are you sure? (yes|no) [no]: yes ok, proceeding. Please enter sysadmin password to confirm 'system headswap': Restoring the system configuration, do not power off / interrupt process ... Broadcast message from root (Mon Apr 30 13:44:10 2018): The system is going down for reboot NOW!

10. After the headswap process completes, verify the file system status.

# filesys status The filesystem is enabled and running.

NOTE:

If an unserved-mode license is used, you might be required to re-activate licenses on the new instance.

Use the elicense check-out and elicense check-in commands to obtain licenses from the DDVE.

If you experience an invalid key magic issue after a headswap, set the passphrase on the new DDVE system, and

run the headswap ddboost user revoke token-access sysadmin command.

If the DDVE was attached to an AV-server and you experienced a certificate authentication issue after a

headswap, detach and re-attach the DD from the AV-server. The AV-server regenerates the certificate and

imports it to DD.

Completing Initial DDVE Configuration 35

Recovering the DDVE instance The system recovery procedure recovers a DDVE instance from failure of the head unit, NVRAM disk, metadata disks, or any combinations of these components. The head unit is the DDVE root disk.

Prerequisites

System recovery between the same DDOS versions is recommended. When the same DDOS version is not available, system recovery can be done with a later DDOS version. The DDOS version compatibility rules are the same as the RPM upgrade.

A static IP address that is configured using DDVE interfaces (CLI or UI) is not recommended. If a static IP address is configured on the network interface in the original DDVE, the same configuration is restored on the new head. This scenario might cause a network disconnection.

Generally, instead of configuring a static IP address using DDVE interfaces, configure it in the cloud provider environment. The DDVE uses DHCP to obtain the static IP address that you configure in the cloud environment.

If you are already using a static IP address that is configured within DDVE, and a disconnection occurs after following these steps, power off the DDVE. Then add an additional network interface to the new DDVE, and login using the IP address of this interface. Finally, enable or reconfigure the primary network interface on the new head, preferably using DHCP.

About this task

If both vNVRAM disk and metadata disks are available, use Recovering DDVE with system headswap on page 34.

Steps

1. Create instance B with the same configuration as instance A. It must include the same memory size, maximum capacity, metadata disk capacity, and role. The instance type can be a new generation type that the DDOS version supports.

2. Enable object-store:

# storage object-store enable Object-store is enabled.

3. Set object-store profile:

a. Set the passphrase to match system A, otherwise, the recovery fails to proceed. b. Set the same s3 bucket name from system A:

# storage object-store profile set A passphrase needs to be set on the system. Enter new passphrase: Re-enter new passphrase: Passphrases matched. The passphrase is set DDVE is running in AWS. Role-based access will be used to access s3. Enter the bucket name: Object-store endpoint needs the Baltimore CyberTrust Root certificate to be imported. Do you want to import that certificate with below fingerprint? D4:DE:20:D0:5E:66:FC:53:FE:1A:50:88:2C:78:DB:28:52:CA:E4:74 (yes|no) [yes]:

Profile is set.

# storage object-store profile set

c. Follow the rest of the CLI prompts.

4. Add EBS volumes to the active tier:

NOTE: Add EBS volumes to match or exceed the capacity of system A .

# storage add dev3 Checking storage requirements...done Adding dev3 to the active tier...done Updating system information...done dev3 successfully added to the active tier.

36 Completing Initial DDVE Configuration

5. Run the system recovery precheck:

# system recovery precheck from object-store Recovery precheck passed. Use start command to start the recovery.

6. Run the recovery:

# system recovery start from object-store System recovery has started. Use status command to check the status.

7. Check the recovery status:

# system recovery status System recovery is running: stage 2 of 6 (attaching object-store)

NOTE: The system reboots during the recovery process.

8. Check that the filesys status after the recovery process completes:

Troubleshooting performance issues You can check DDVE performance statistics as follows:

With native tools in AWS

You can also use the following to monitor benchmark performance:

perf Extensions to DDOS for DDVE on page 39 provides more information about commands.

CPU Performance

The two key statistics for CPU performance are:

CPU usageCPU usage as a percentage during the interval CPU readyThe percentage of time that the virtual machine was ready, but could not get scheduled to run on the physical

CPU. This counter might not be displayed by default.

If these counters are high, there may be a performance problem on the hypervisor host.

Memory Performance

Memory swappingThe key statistic for memory performance, which is the current amount of guest physical memory swapped out to the virtual machines swap file.

Virtual Disk Performance

The key statistics for virtual disk performance are:

I/O throughputA decrease in these values indicates a performance issue. I/O latencyAn increase in read and write latency values indicates a performance problem. Failed commandsAn increase in the average number of outstanding read and write requests indicates a performance problem.

Best Practices for Working with DDVE in the Cloud

This chapter includes the following topics:

Topics:

ASUP configuration AWS licensing Storage best practices Security best practices

ASUP configuration We recommend enabling AutoSupport (ASUP) in DDVE. Although Experience, Secure Remote Services (ESRS) is not yet supported in AWS, you can use the email transfer server to transfer ASUP files.

About this task

Set up the following items to ensure that ASUPs and alert emails from the DDVE instance are sent to Dell EMC. 1. Administrator: Specify a password and email address for the administrator. 2. Email/location: Specify the mail sever to use to send outgoing alert and ASUPs to recipients. Recipients are subscribers to

groups. A default group is created that contains the email addresses of the administrator and a Dell EMC email address, autosupportalert@autosupport.datadomain.com. The location field is for information only.

3. Review the summary carefully. The default email address for alerts and autosupport emails is autosupportalert@autosupport.datadomain.com. A detailed autosupport and an alert summary are scheduled to run daily at 6:00 AM system time.

AWS licensing A DDVE license is node-locked, which means the same license cannot be used on multiple DDVE instances. To facilitate DDVE license management, if multiple DDVEs are being deployed, use served-mode licenses .

NOTE:

A DDVE license might become invalid after removing the first NIC ethV0.

If there is a head swap, a license continues to work on a new DDVE instance if served-mode licenses are used.

Otherwise, you must re-activate the license.

You can create a new DDVE instance from an AWS snapshot. For served-mode licenses, a license is automatically

checked out from the license server on the new instance if the license server has sufficient licenses. Otherwise, you

must re-activate the license.

Storage best practices

Use the appropriate storage type

Use GP3 EBS volumes for the root disk, NVRAM disk, and metadata disks.

A

48 Best Practices for Working with DDVE in the Cloud

Migrate from GP2 to GP3

Amazon EBS Elastic Volumes enable you to modify the volume type from GP2 to GP3 without detaching volumes or restarting instances, which means that there are no interruptions to your applications during modification.

To modify an Amazon EBS volume using the AWS Management Console:

1. Open the Amazon EC2 console. 2. Choose Volumes, select the volume to modify, and choose Actions, Modify Volume. 3. The Modify Volume window displays the volume ID and its current configuration, including type, size, IOPS, and throughput.

Set new configuration values as follows: Volume Type: Select GP3 IOPS: Set 3000 Throughput (MB/s): Set 125

4. Select Modify. When prompted for confirmation, select Yes.

NOTE: The recommended IOPS and throughput values for a GP3 volume are 3000 and 125, respectively. These values

represent the baseline performance of a GP3 volume. If you set higher IOPS and throughput values, an additional fee is

charged: $0.005 per IOPS per month over 3,000, and for throughput, $0.04 per MiB/s per month over 125 MiB/s.

Object storage specifications

The following table lists the supported instance types and their storage configuration for object storage.

Metadata disk storage is recommended to be 10% of the total capacity. Each metadata disk is recommended to be 1 TiB.

256 TB M5.8xlarge 250 GiB 10 GiB 2048 GiB 1-13

NOTE:

If the incorrect instance type is used, the system displays an alert for an unsupported virtual hardware configuration.

The metadata requirements that are listed above are based on a 10x deduplication ratio and a 2x compression ratio. For

workloads with a higher deduplication ratio, more metadata storage is required.

The maximum number of metadata disks that you can add to a DDVE instance in AWS is 24.

Block storage specifications

The following table lists the instance types and storage types that are required for block storage.

Metadata disk storage expansion notes

Dell EMC recommends to use 10% of the system capacity as the metadata storage, where each metadata disk size is one TiB. This metadata storage recommendation is based on 10X deduplication ratio and 2X compression. For workloads with a higher deduplication ratio, more metadata storage may be required. If metadata storage usage exceeds 80%, an alert is generated. Add a metadata disk to the DDVE immediately to avoid running out of space.

The DDOS Administration Guide provides a procedure for expanding storage. Dell EMC recommends that you always use 1 TiB metadata disks.

50 Best Practices for Working with DDVE in the Cloud

Spindle group

You are not required to specify a spindle group when adding metadata disks. The spindle group assignment is balanced automatically when adding storage. Do not set or change the spindle group settings manually. Run the storage show all command to verify that each data volume is assigned to a different spindle group.

Object storage bucket configuration notes

The bucket that is provided during file system creation must be empty, otherwise file system creation fails. When the file system is destroyed, the associated bucket and the objects it contains are not automatically deleted or

removed. The bucket must be intentionally deleted to avoid incurring the cost for the content stored in the bucket. Do not enable S3 versioning on the bucket. Doing so incurs additional cost because older versions of the objects are

retained, although they are removed by the GC cycles. Do not configure any life-cycle policy on the bucket as it might result in loss of critical data.

Converting from evaluation to production

Rather than convert an evaluation version of DDVE to a production version, Dell EMC recommends a fresh deployment. If you decide to convert from an evaluation version to production version, Dell EMC recommends that you:

Destroy the existing file system Delete any small data disk (not the root or NVRAM disks) Configure new disks according to the recommendations in this guide

Security best practices

Avoid Public IP address

To prevent brute force attacks on the DDVE, it must not be configured with a public IP address.

Secure access

The following table illustrates the different authentication methods that are supported by DDVE.

Table 10. Access Types and Authentication

Access Type Authentication Methods

GUI username/password X509 certificates

SSH username/password

SSH key pair

REST API username/password X509 certificates

For better security, we recommend you disable the username/password based user authentication. If the username/password based authentication is desired, we recommend that you configure a stronger password.

NOTE: Password based login should not be disabled if you want to configure Avamar Virtual Edition, NetWorker, or other

backup software to connect to DDVE in AWS, because password authentication is used for communication between them.

Because AWS is a public cloud, pay attention to the security in your deployment. We suggest these best practices:

Use public key based authentication for SSH access Use certificate based authentication for DDSM access Do not configure public IP for DDVE in AWS, if possible Use external KMIP server to store encryption keys Enable encryption for DDFS and replication

Best Practices for Working with DDVE in the Cloud 51

After a DDVE deployment from the market place, DDVE SSH login with a username and password is enabled. The default password for the sysadmin user is the EC2 instance ID of the DDVE instance. At the first login, a password change is required. The EC2 key access pair associated with the sysadmin user is an optional alternative to username and password authentication.

IP Tables feature

After protecting the DDVE using secure setup, within the DDVE you can filter the network traffic that enters by using the iptables feature. For more configuration information, see the DDOS 6.2 Command Reference Guide's Net Filter section.

Security rules settings

Since the DDVE in AWS is always running in a VPC, the VPC should be configured so that only required and trusted clients have access to the DD system. The following tables show the TCP and UDP ports that are used by the DD system for inbound and outbound traffic, and which service makes use of them. Consider the following information when configuring VPC firewall rules. For additional information, see Amazon EC2 Security Groups for Linux Instances.

Inbound rules

The following are the inbound ports used by DDVE.

Table 11. Inbound ports used by DDVE

Port Service Description

TCP 22 SSH Used for SSH (CLI) access and for configuring DDVE.

TCP 443 HTTPS Used for DDSM (GUI) access and for configuring DDVE.

TCP 2049 DD Boost/NFS Main port used by NFS - can be modified using the nfs set server-port command which requires SE mode.

TCP 2051 Replication/DD Boost/ Optimized Duplication

Used only if replication is configured (run replication show config command on DD system to determine). This port can be modified using replication modify.

TCP 3009 SMS (system management) Used for managing a system remotely using DDSM. This port cannot be modified. This port will also need to be opened if you plan to configure replication from within the DDSM, since the replication partner needs to be added to the DDSM.

Depending on the protocol that is used to backup data to DDVE, additional ports are enabled with inbound firewall rules.

Outbound rules

The following are the outbound ports that are used by DDVE.

Table 12. Outboard ports used by DDVE

Port Service Description

UDP 123 NTP Used by the DD system to synchronize to a time server.

TCP 443 HTTPS Used for DDVE to be able to communicate with outside services.

TCP 2049 DD Boost/NFS Main port used by NFS - can be modified using the nfs set server-port command which requires SE mode.

TCP 2051 Replication/DD Boost/ Optimized Duplication

Used only if replication is configured (run replication show config on DD system to determine). This port can be modified using replication modify.

Networking Best Practices for DDVE in the Cloud

This chapter includes the following topics:

Topics:

Network setup in AWS Network infrastructure setup

Network setup in AWS Network configuration requirements and recommendations are provided.

VPC Architecture

It is recommended that you use a public or private subnet architecture to deploy the DDVE in a private subnet. This architecture secures the DDVEs (VMs) with the appropriate use of various VPC components such as route tables, access control lists, security groups, and so on.

Public IP address

To protect the DDVE from potential attacks over the open Internet, do not expose the DDVE by using a public IP address directly over the Internet. It is recommended that you use VPN connections between different geographical regions (VPCs). For example, the replication between different VPCs, different cloud regions, cloud to on-premises, and on-premises to cloud can occur over the secure VPN connection.

Network interfaces

You can add multiple network interfaces to the DDVE instance. The maximum number of network interfaces varies by instance type. See Elastic network interfaces for more information.

Custom primary private IP address

If you want to assign the network interface with a custom private IP address, follow the steps in Create a network interface, choose Custom when adding a private IP address, then attach it to the DDVE instance.

Within DDVE, there is no requirement to configure the interface to a static IP address. Configuring the network interface using DHCP, which is enabled by default, is recommended.

Object store connectivity

The DDVE object store feature must connect to its object storage, for example, to the S3 bucket. The object store communication is over HTTPS, so the outbound security group setting must allow communication over port 443. Different ways to enable DDVE connectivity to the object store are available. Out of the following three options, only the third option (using VPC endpoint) is recommended.

Public IP address from the public subnet - Do no use.

B

54 Networking Best Practices for DDVE in the Cloud

Network Address Translation (NAT) - If the private subnet is configured to use NAT, the DDVE can communicate to object store over NAT.

VPC endpoint for accessing the Amazon S3 - VPC does not require the DDVE to have a public IP address to communicate to S3. It uses the private IP address instead. (In this case, an Internet gateway, NAT, or virtual private gateway are not required to access S3.) Using VPC endpoint allows the traffic to the S3 endpoint to stay within the Amazon network and is routed internally to S3.

NOTE:

See to Role based access for S3 object store for configuring the DDVE to access the S3 bucket securely.

The S3 bucket that is created for DDVE use, must be in the same region that the DDVE is in.

For information, see AWS documentation.

Network infrastructure setup This section describes security group restrictions for AWS.

Security groups

The security groups restrict access to an instance based on

1. Port 2. IP range 3. Security group (its own or another)

Inbound control

The security groups are stateful which means that the responses to the inbound traffic will be allowed to go out regardless of outbound rules. The following are the inbound ports that are allowed for DDVE.

Table 13. DDVE Inbound Ports

Port Service Description

TCP 22 SSH Used for SSH (CLI) access and for configuring DDVE.

TCP 443 HTTPS Used for DDSM (GUI) access and for configuring DDVE.

TCP 2049 DD Boost/NFS Main port used by NFS - can be modified using the nfs set server- port command which requires SE mode.
