6 Getting Started

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

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, Dell EMC recommends 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. The S3 bucket must be created in the same region where the DDVE is running. There must be a separate bucket for each DDVE.

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.

Topics:

Introducing DDVE DDVE features 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 (DD OS), and includes the DD System Manager graphical user interface (GUI) and the DD OS 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 features Resource configurations depend on your DDVE configuration. For features for cloud configurations within the admin guide for your specific cloud provider, see DDVE cloud features on page 8.

The DD OS Administration Guide, DD Boost OST Guide, and DD Boost for Partner Integration Administration Guide provide additional information about the supported protocols and features.

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

Deploying DDVE This chapter includes the following topics:

Topics:

Introducing VMware Cloud on AWS VMC system configuration requirements Deploying DDVE in VMware Cloud on AWS Configuring DDVE in VMC using DD System Manager Supported stream counts VMware Cloud on AWS commands Running system headswap on DDVE in VMC Running system recovery on DDVE in VMC Expand metadata storage

Introducing VMware Cloud on AWS DDVE in VMware Cloud on AWS (VMC) provides a data protection solution that enables you to protect your operational data in the cloud and to backup and restore data into the cloud object store. This section describes first-time setup procedures, and includes how to manage and monitor DDVE in the VMC environment.

VMC system configuration requirements Ensure that your system meets the requirements for VMC configuration.

VMC uses standard/vSAN metadata disks.

The instance type in the following table is for logical significance.

Table 3. VMC System Requirements

Instance Type DDVE Capacity #vCPU, Memory System Disk

Standard_VMC_16 16 TB 4, 16 GB 250 GiB Root disk, 10 GiB vNVRAM disk

Standard_VMC_32 32 TB 4, 24 GB 250 GiB Root disk, 10 GiB vNVRAM disk

Standard_VMC_96 96 TB 8, 64 GB 250 GiB Root disk, 10 GiB vNVRAM disk

Deploying DDVE in VMware Cloud on AWS

Prerequisites

For deploying DDVE in VMware Cloud on AWS (VMC) on S3 object store:

Ensure that you have an AWS account linked to your VMWare cloud account. The SDDC in VMC will be connected to an AWS account during creation. Ensure that the subnet selected in the AWS

account is in the same region as the SDDC. Ensure that you create the AWS S3 bucket that is used by the DDVE in the same region as the SDDC and within the same

AWS account.

3

10 Deploying DDVE

Ensure that the S3 traffic from VMC is routed internally toward the AWS infrastructure. (During the SDDC in VMC setup, you should have already linked your AWS/VPC subnet account to the VMC account.)

Ensure that you create the S3 endpoint so that the object store traffic is routed within the AWS infrastructure.

The VMC documentation provides additional details.

Steps

1. To upload the OVF file, from the vSphere Client navigation pane, under Compute Resource Pool, right-click the DD resource and select Deploy OVF Template.

2. Follow the steps in the Deploy OVF Template wizard:

a. Select the OVF template. b. Select the virtual macnine name and folder where you want to deploy the DDVE instance. c. Select the compute resource pool. It may be one of the nodes in the cluster or a pre-configured resource pool. Ensure

the compatibility checks succeed. d. Review and verify the template details. e. Select the deployment configuration. f. Select the storage for the metadata disks. g. Select the parameters for the network. h. Review the configuration details and exit the wizard.

3. Monitor the progress of the deployment under Recent tasks.

4. While the DDVE instance is being deployed from the AWS console, create an AWS S3 bucket.

NOTE:

To avoid additional costs and potential performance issues, ensure the S3 bucket and DDVE in VMC are available in

the same region.

Do not enable S3 versioning for the bucket that is associated with the DDVE, for the following reasons:

S3 versioning requires more storage and incurs increased storage costs. For example, even though DDVE's

Garbage Collection process deletes the objects that are not needed, those objects still consume storage.

S3 versioning can result in performance issues.

5. From the VMC console, power on the DDVE instance.

6. On the Settings page, select Add New Device and add the metadata storage.

Configuring DDVE in VMC using DD System Manager DD System Manager guides you through DDVE configuration in VMC.

About this task

NOTE:

Recommended metadata storage is 10% of the total capacity.

The default password changeme is set for DDVE in VMC. It is not required to log in to the VM web console to set a

password.

DHCP is enabled on the DDVE system by default. If the DHCP service is available, the DDVE system receives IP

addresses from the DHCP server.

Steps

1. Log in to the DD System Manager by entering the IP address of the DDVE into the web browser.

2. For the Apply your license step, select one of the three license types available in the drop-down menu, and then click Apply:

Pre-install Evaluation: Provides 45 days of limited access to DDVE software for evaluation purposes and may only be used in a non-production environment.

NOTE: If you begin the configuration with the evaluation license, but want to purchase a license later, you need the

Node Locking ID for the DDVE instance. Click Administration > Licenses to view the Node Locking ID.

Deploying DDVE 11

License File: Node locked license (unserved mode) License Server: Served mode license

3. Accept the End User License Agreement (EULA).

4. In the Configuration wizard, select File System and click Yes.

5. To configure the DDVE on S3 storage, select Configure Active Tier > Enable Object Store.

6. Enter the passphrase.

Make note of this passphrase ( you need it later).

7. Enter the S3 bucket name that is created in the same region as the DDVE instance.

8. Import the Baltimore CyberTrust Root certificate to communicate with AWS S3 Object Store.

9. Add the metadata storage.

10. Review the summary and click Submit to create the file system and enable it.

11. Review File System Creation Complete page and click OK.

12. To view the space usage and availability details for the S3 Object storage and local metadata storage, select Data Management > File System.

13. Optional: Configure the following settings:

a. Under System settings, update the sysadmin password or configure Alert and Autosupport email settings. b. Under DD Boost Protocol, create a DD Boost storage unit and assign an owner.

Running system headswap on DDVE in VMC The system headswap command recovers DDVE with head unit failure in VMC.

Prerequisites

Ensure that the vNVRAM disk and metadata disks from system A (original system) are available. If either vNVRAM disk or any metadata disk is not available, use the command system recovery from object-store instead.

About this task

This procedure copies the vNVRAM disk and metadata disks from system A (original instance) to system B (new instance).

Steps

1. Create instance B with head unit (root disk only) with the same instance type as system A.

2. Detach the vNVRAM and metadata storage from the broken head unit. On the Edit Settings page of the broken head unit, remove the vNVRAM and metadata storage.

NOTE: Do not select the checkbox Delete files from datastore.

3. Attach the vNVRAM and metadata storage to instance B head unit.

a. On the Edit Settings page of instance B head unit, select ADD NEW DEVICE > Existing Hard Disk.

b. Select files from the broken head unit and add to instance B head unit one by one.

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

4. Set the system B passphrase to match the system A passphrase.

If the passphrases do not match, the headswap fails.

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

5. 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 with system B.

6. Run system headswap.

NOTE: The system restarts 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.

14 Deploying DDVE

** 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!

7. Ensure that the system is running after the headswap process is complete.

# filesys status The filesystem is enabled and running.

Running system recovery on DDVE in VMC The system recovery command recovers DDVE with a head unit, vNVRAM disk, or Metadata disk failure.

Prerequisites

About this task

If both the vNVRAM disk and the Metadata disks are available, use the system headswap command instead.

Steps

1. Create instance B with the same configuration as instance A, including instance type and metadata disk capacity.

2. Enable object-store.

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

3. Set object-store profile:

a. Set the passphrase to match the system A passphrase. Otherwise, the recovery fails. b. Set the S3 bucket name the same as 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]:

c. Follow the remaining CLI prompts.

4. Add metadata disks to the active tier to match or exceed the capacity of system A.

# storage add dev3 Checking storage requirements...done Adding dev3 to the active tier...done

Deploying DDVE 15

Updating system information...done dev3 successfully added to the active tier.

5. Run 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 the status after the recovery process completes.

# filesys status The filesystem is enabled and running.

Expand metadata storage Expand metadata storage by adding new 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. Observe the recommended increment size of 1024 GiB. Shrinking metadata disk size is not supported.

Steps

1. Log in to the vShpere Client. From the navigation pane, under Compute Resource Pool, find your DDVE, and stop it.

2. Right-click the VM, and select Edit Settings...

3. Select the metadata disk that you plan to expand.

NOTE: You cannot expand the first metadata disk.

4. Increase the size of the selected metadata disk (for example, from 1 TB to 2 TB).

5. Click OK.

16 Deploying DDVE

6. To increase the size of other metadata disks, repeat Step 3 and Step 4.

7. Start the DDVE.

8. To confirm the disk size change, use the Disk show hardware or Storage show all command.

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

10. Expand metadata storage with the filesys expand command.

11. Enable file system with the filesys enable command, and check file system status with filesys status command.

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

Administering DDVE This chapter includes the following topics:

Topics:

Upgrading M5 instance type Adding virtual storage Extensions to DDOS for DDVE DDVE-only commands Modified DD OS commands Unsupported DD OS commands Troubleshooting performance issues

Upgrading M5 instance type

About this task

You can upgrade the DDVE instance from m5-xlarge > m5.2xlarge > m5.4xlarge.

Steps

1. Power off the system using the system poweroff command.

From the AWS console, check that the DDVE instance is in the stopped state.

2. Select Action > Instance Settings > Change Instance Type.

3. Select the new instance type and click Apply.

4. Power on the DDVE from the AWS console.

5. Once the DDVE is powered on, run the command system vresource show to verify the new instance configuration.

Adding virtual storage More virtual storage can be added to the DDVE using the GUI or the CLI.

Using the GUI

In DD SM, click Hardware > Storage > Configure Storage to add the additional devices to the DDVE active tier.

Using the CLI

When you add a new virtual data disk to an existing DDOS file system, use the filesys expand command instead of the filesys create command.

Configuring spindle groups

DDVE 3.1 and above, support 16 spindle-groups. We recommend that virtual disks from the same storage be configured with same spindle-group number. Virtual disks with different storage should be configured with a different spindle-group number. By default, disks are assigned with different spindle-groups. The best practice is NOT to assign spindle-group manually.

perf Extensions to DDOS for DDVE on page 19 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
