Chapter 1: Introduction

Chapter 2: Quick Start Guide

This chapter provides an overview of the initial configurations of Synology DiskStation Manager (DSM). To help you get started with your Synology NAS, perform the following instructions

about drive setup, OS installation, storage initialization, and several built-in services of DSM

management.

2.1 Install drives

As a data storage server, Synology NAS needs at least one 3.5" or 2.5" drive to ensure

functionality. For detailed information on drive installation, please refer to the Hardware Installation Guide via Synology's Download Center.

Back up drives before installation

If your drive comes from an old Synology NAS, please follow the instructions in this article to

perform drive migration. The migration procedures mentioned in the article will help you keep

most of your data. However, we strongly recommend that you back up data on the original

Synology NAS, from which drives are moved, to avoid accidental data loss.

If your drive does not come from a Synology NAS that contains data, you need to back up data

before the installation because the system will format drives and erase all the existing data

during the installation.

Understand RAID types

After the drive installation, you should set up a RAID array to add extra security and

redundancy to your storage space. This section gives you a brief introduction to the RAID

technology and the difference between each RAID type.

RAID (Redundant Array of Independent Disks) is a data storage technology that allows multiple

independent drives to be combined into a RAID array for data redundancy and performance

improvement. In a RAID array, the same data will be stored in different places across multiple

drives to reduce the risk of data loss caused by a drive failure. Moreover, the RAID setup can

boost the read-write performance because data will be striped across drives under certain

RAID configurations.

Different RAID configurations provide different levels of redundancy and performance. The

following is an overview of the RAID types supported by Synology NAS:

Chapter 2: Quick Start Guide

03

Chapter 2: Quick Start Guide

SHR: Synology Hybrid RAID (SHR) is an automatic RAID management system designed

by Synology. SHR provides fault tolerance when there are more than two drives. It is

recommended for novice users because it will automatically deploy drives for the best interest

of your storage space.

Basic: Basic configuration is composed of only one independent drive, so it does not provide

any fault tolerance or performance boost.

JBOD: JBOD (Just a Bunch of Disks) configuration combines all drives into a single drive stack.

Each JBOD drive is regarded as a separate and individual drive volume, so it allows easier

control management of data storage. JBOD configuration does not provide any fault tolerance

or performance boost.

RAID 0: In contrast to JBOD, RAID 0 combines two or more drives and treats them as a single

unit. In RAID 0, data are divided into blocks and split across multiple drives; therefore, the

read-write speed increases with more drives added.

RAID 1: RAID 1 requires at least two drives. In RAID 1, data are mirrored on all drives. Since

the same data exist on all the drives in the array, the volume of the smallest member drive

determines the total capacity of the array. This is the safest option to protect important data,

but the write performance and capacity are relatively limited.

RAID 5: RAID 5 requires at least three drives, and one of the drives is used for fault tolerance.

RAID 5 stripes data blocks across multiple drives and distributes redundancy information,

called parity, across all of the drives in the array. Upon failure of a single drive, the lost data

can be reconstructed with the parity existing on the rest of the drives.

RAID 6: RAID 6 requires at least four drives. RAID 6 features double distributed parity, so it

has better data redundancy than RAID 5. However, because RAID 6 needs to write two parity

blocks on all member drives, the write performance is slower than RAID 5.

RAID 10: RAID 10 requires at least four drives. The drives have to be even because drives are

combined into groups of two in which data is mirrored and striped. RAID 10 features the

performance of RAID 0 and the data protection of RAID 1.

RAID F1: RAID F1 requires at least three drives. Like RAID 5, RAID F1 implements data block

striping and distributes parity data across all member drives. The only difference is that one of

the drives will bear more parity information, so it will age faster, which prevents all the drives

from coming to the end of their lifespan at the same time. RAID F1 is recommended for an all-

flash array.

Notes:

RAID F1 and SHR are only available on specific models. Refer to the specifications of each model for detailed information.

Chapter 4: Storage & Virtualization

4.1 Storage Manager

Storage Manager allows you to organize the storage units on your Synology NAS, monitor

overall storage use, and inspect the health of all your drives.

Key Terms:

Before using Storage Manager, it can help to familiarize yourself with the following terms:

Storage Pool:

Combine one or more drives into a single storage unit called a storage pool. A storage pool can be configured to be protected by a data storage technology known as Redundant Array of Independent Disks (RAID).

RAID:

RAID is a data storage technology that aggregates multiple physical drives into one or more logical units for improved fault tolerance, performance, and storage capacity.

Supported RAID types vary according to your Synology NAS model. For details, refer to this article and the product specs of your Synology NAS.

Volume:

Volumes are created on top of storage pools and provide the basic storage space on your Synology NAS. All of your shared folders, documents, and package data will be stored here.

Chapter 4: Storage & Virtualization

33

Chapter 4: Storage & Virtualization

Storage Pools and Volumes

Create at least one storage pool and volume to start storing data on your Synology NAS. For

more information, refer to the instructions in Chapter 2.7.

You can go to Storage Manager > Overview to find key information about your storage system,

such as overall system status, volume usage, drive information, and scheduled tasks.

View and manage all your storage pools and volumes at Storage Manager > Storage. The actions

you can perform here depend on your Synology NAS model and configurations:

Change the RAID type of a storage pool without losing existing data.

Convert a storage pool from single-volume support to multiple-volume support.

Add or replace drives to expand the capacity of a storage pool and volume.

Enable SSD TRIM to optimize the performance of an SSD-only storage pool.

Perform or schedule data scrubbing on a storage pool to maintain data consistency.

Perform file system defragmentation to improve a volume's file access performance.

Further reading

For more information, refer to the articles under Storage Pool and Volume.

Hot Spare

Hot spare drives are standby drives that allow your Synology NAS to automatically repair

degraded storage pools. You can assign hot spare drives to protect storage pools with a drive

fault tolerance of one or more drives at Storage Manager > Storage > Hot Spare.

When a drive crashes and causes a storage pool to degrade, the hot spare drive replaces the

crashed drive, allowing the storage pool to recover. For more information, refer to this article.

34

Chapter 4: Storage & Virtualization

Notes:

Please note the following requirements and limitations:

The RAID type of the storage pool must have a fault tolerance of 1 or more drives (i.e., RAID 1, RAID 5, RAID 6, RAID 10, RAID F1, and SHR comprising at least two drives).

The capacity of the hot spare drive must be equal to or larger than the capacity of the smallest drive in a RAID 1, RAID 5, RAID 6, RAID 10, or RAID F1 storage pool.

The capacity of the hot spare drive must be larger than or equal to the capacity of the largest drive in an SHR storage pool.

HDDs and SSDs can each only be assigned as hot spares to storage pools of the same drive type. Only SSD hot spares can protect SSD storage pools, and only HDDs can protect HDD pools.

SSD Cache

SSD cache is a cost-effective way to improve the performance of HDD arrays. It improves

random access by storing frequently accessed data on the SSDs of an SSD cache mounted on

a volume or LUN. Note that this feature is only available on specific models. To find out which

Synology NAS models support this feature, refer to this article.

There are two types of SSD cache:

A read-only cache uses one or more SSDs to store frequently read data and accelerate random

read performance. No data loss will occur in the event of SSD failure because this cache

mode only stores copies of data from the volume.

A read-write cache uses at least two SSDs to create a fault-tolerant cache. The read-write cache

first writes data to the SSDs to improve the random read/write performance and accelerate

data access speed.

Both types or modes of SSD cache can consist of up to 6 SSDs and must be comprised of

drives of the same type. For more information on requirements and how to set up an SSD

cache, refer to this article.

If you are unsure what is the best SSD cache size for your use case, we strongly recommend

running an analysis in Storage Manager > Storage > SSD Cache Advisor beforehand.

The SSD Cache Advisor analyzes your current data use patterns and recommends a suitable

SSD cache size for your selected volume. Allow the initial analysis to run for at least seven days

for more accurate results.

For more information about SSD Cache Advisor, refer to this article.

Account Protection from the Control Panel. Proper firewall settings let you control which IP

addresses or services have access to DSM.

The Auto Block and Account Protection features help make sure that your Synology NAS is

safe from brute-force attacks. They block IP addresses or DSM accounts with too many failed

login attempts within a specified period. When there are attempts to sign in to your NAS or

its services from a specific IP with random username/password combinations, Auto Block

prevents users of that IP address from gaining access to the NAS. Account Protection works

the same way but focuses on individual accounts, blocking users' access to specific accounts.

Certificates from Let's Encrypt or other certificate authorities help secure connections to

and from DSM. When you connect to DSM through a web browser, certificates encrypt

the information sent between DSM and the browser to prevent any possible information

interception.

Synology QuickConnect White Paper

DDNS

DDNS (Dynamic Domain Name System) is an efficient way to allow external access to Synology

NAS. It simplifies connections to your Synology NAS over the Internet by mapping a hostname

to its IP address. For example, you can access your Synology NAS using a DDNS hostname (e.g.,

"www.john.synology.me") instead of using an IP address (e.g., "10.17.1.1").

DDNS hostnames can be configured in Control Panel > External Access > DDNS. To learn how to

register a DDNS hostname for your Synology NAS, refer to this article.

9.2 Network Settings

In most cases, you can start exploring services on your Synology NAS right after installing DSM

without the need to configure network settings. If there is a need to customize the settings, go

to Control Panel > Network.

53

Chapter 9: Network

The following introduces some generic network options available in Control Panel > Network >

General:

Change the hostname: A hostname is a unique and absolute label for a device on a network

and is used to identify the device during network communication. To edit the hostname of

your Synology NAS, enter a new name in the Server name field under the General section.

Assign the default gateway: A gateway connects multiple different networks so that the data

from your Synology NAS can be transmitted to other networks. The default gateway will be

the device used if no alternative routes are specified. To assign the default gateway, click the

Edit button beside Default gateway and arrange the priority order of connected gateways.

Specify DNS servers: The Domain Name System (DNS) resolves easy-to-memorize Internet

addresses to the numeric addresses that Internet-connected devices use. When your

Synology NAS connects to a domain name such as "www.synology.com", its DNS server is

responsible for querying the site's IP address "210.61.203.200", allowing your Synology NAS

to access the websites information. Under the General section, you can tick Manually configure DNS server and specify a preferred DNS server along with an alternative one.

Connect via a proxy server: A proxy server functions on behalf of client devices to access

resources on the Internet. To specify a proxy for your Synology NAS, tick Connect via a proxy server under the Proxy section, enter the Address and Port, and then click Apply.

For more information about general network settings, refer to this article.

Chapter 9: Network

Manage network interfaces

A network interface serves as a medium that connects your Synology NAS to local networks

or the Internet. There are three connection types for network interfaces you can configure in

Control Panel > Network > Network Interface, as listed below:

Dynamic IP: Your Synology NAS will obtain a dynamic IP address automatically from a DHCP

(Dynamic Host Configuration Protocol) server (e.g., a router) after DSM has been installed.

If you have changed the connection type of Synology NAS but would like to use dynamic IP

mode again, select the specified network interface, click Edit, and tick Get network configuration automatically (DHCP) at the IPv4 tab.

Static IP: If you already have some fixed IP addresses, you can adopt this connection type

for network interfaces. For enterprise use, we suggest assigning a static IP address to your

Synology NAS because this makes it easier to be managed by IT administrators. To learn how

to set up a static IP address on DSM, refer to this article.

PPPoE: If your Synology NAS connects to the Internet via a DSL or cable modem and you have

purchased a PPPoE (Point to Point Protocol over Ethernet) service from your ISP, you can

adopt this connection type to allow your NAS to directly connect to the Internet without a

router. To learn how to enable PPPoE connections on DSM, refer to this article.

In Control Panel > Network > Network Interface, you can configure more settings related to the

network interfaces of your Synology NAS, including IPv6 connections, VPN client settings, and

Link Aggregation. The following section will briefly introduce these options and guide you on

their configurations.

55

Chapter 9: Network

Set up IPv6 connections

Besides connections to the Internet via the IPv4 protocol, DSM also supports IPv6 address

structure through the following two strategies (they can be adopted simultaneously):

Dual stack: An IPv4/IPv6 dual-stack configuration lets you configure your Synology NAS with

both an IPv4 and an IPv6 address. Use this approach to access resources across IPv4 and

IPv6 network environments.

Tunneling: Tunneling involves transmitting one protocol inside another through

encapsulation. This method allows your Synology NAS to encapsulate IPv6 packets in IPv4

packets and send them across IPv4 networks.

To learn how to set up an IPv6-integrated network interface, refer to this article.

services to prevent latency, congestion, and packet loss. If you wish to limit the traffic of a

specific service, you can specify its guaranteed and maximum bandwidths on the Traffic Control page.

To learn how to create a traffic control rule, refer to this article.

Configure static routes

In Control Panel > Network > Static Route, you can add static routes to the routing table in DSM.

By doing so, service traffic on your DSM can be transmitted via different paths according

to network destinations, which improves the routing efficiency of gateway devices in your

network environment. To learn how to set up static routing, refer to this article.

9.3 Proxy Server

A proxy server acts as a gateway that forwards web requests and data between clients on your

network and servers on the internet.

58

Chapter 9: Network

You can use a proxy server as a firewall, to filter web traffic, manage shared network

connections, and speed up responses for common web requests.

(i.e., domain names such as "www.synology.com") into IP addresses (e.g., "210.61.203.220"),

allowing users to easily access web pages, computers, or other resources across networks.

In DSM, DNS service can be set up via DNS Server. This package is recommended for website

hosting and is necessary for Active Directory domain services. It has the following features:

Master and slave zones: The DNS boundaries that allow granular control of DNS

components. You can store DNS information in one master zone (containing a read/write

copy of data) and multiple slave zones (containing read-only copies of data) to ensure the

high availability of DNS service.

DNS forwarding: An alternative method of DNS resolution that will be used when DNS Server

cannot find matching IP addresses in your zones.

TSIG keys: Safeguard the synchronization of your DNS files with encryption.

Split-horizon DNS: A function that provides each client with customized DNS information;

this can help improve the security and privacy management of DNS zone records.
