Management

A powerful operating system requires powerful controls, especially when shared among multiple users. DSM helps you configure, maintain, and monitor your NAS in a meticulous manner - and it doesn't take an IT professional to figure out how.

Accounts and Privileges

Sharing a DiskStation easily and securely

DSM's native account management functions let you extend the benefits of a DiskStation to family and friends - exactly the way you want. Assign specific storage quotas, speed limits, and access rights to individual users, or divide accounts into groups so that you can manage them all with ease and speed. Each person may share files with other designated users, yet keep his private "Home" folder away from prying eyes. Enterprises and power users, moreover, can draw on the advantages of the following features:

Application privileges

Access to applications and packages can be controlled based on individual account, user group, or IP address. Not only does this boost efficiency and consistency when managing permissions, but you are also able to restrict the use of certain applications to people in the local network only.

Windows ACL

Support for Windows ACL offers IT administrators the ability to achieve file-based granular access control via an intuitive user interface. Enterprises can allocate read, write, or administration permissions to its different departments, or even delegate their managers to determine the access rights to specific files or folders, ensuring flexibility and a high level of security at the same time.

Windows AD and LDAP

For companies that have established domain user accounts through Windows Active Directory (AD) or LDAP, there is no need to maintain two sets of credentials - DSM integrates with your existing account system seamlessly. A Synology NAS can even act as an LDAP server itself.

Network Management

Remotely accessing your data center

You might be commuting or travelling every day, and want to connect to your personal storage center on the go. DSM offers a variety of options and services that make connecting to your Synology NAS the most intuitive, painless, and flexible — benefiting NAS beginners and professional administrators alike.

Link aggregation

Link Aggregation allows you to tailor the behavior of your network ports in terms of network reliability and performance, unlocking potentially higher transfer speeds and failover support for environments with multiple clients, such as small or medium offices. DSM supports the following modes: Adaptive Load Balancing, Active-standby, 802.3ad dynamic, and Balanced XOR. Adaptive Load Balancing allows outgoing and incoming traffic to be distributed evenly on each network interface without special switch configuration required, thus reducing operation expenditure.

QuickConnect

Synology QuickConnect provides a comprehensive solution to access everything you would ever need, wherever you are, from any browsers or mobile devices - without having to configure your router at all. Better yet, it's completely free. Sign up for a QuickConnect ID and start enjoying anywhere access right away! Learn more

DDNS

For those who prefer to set up port-forwarding and do everything themselves, Synology also provides free DDNS services so you can pick your own domain name and easily connect from anywhere. Say goodbye to entering your DiskStation's IP address every time.

IPv6

DSM services are compatible with IPv6, the next-generation Internet protocol, making sure your DiskStation is ready for the future.

Service-based static routing

Administrators familiar with their network infrastructure may manually configure the optimal static route for specific services to boost routing efficiency.

Maintenance

Routine work made smart and automatic

Servers used to require constant attention. DSM, however, is not only equipped with an easy-to-use interface, but also strives to centralize and automate as many tasks as possible. It intelligently gathers and organizes all information required for maintenance, saving your time for the real emergencies.

Resource Monitor

Keep an eye on the performance of a DiskStation's CPU, memory, disks, and volumes in real-time. View all running and idle tasks. Or view and manage which users are currently connected and using system resources.

Storage Analyzer

It helps you visualize the massive streams of data generated on your NAS. You can see how volumes and shared folders are used, who the heavy users are, and the disk usage trends overtime, as well as identify and delete duplicated files.

S.M.A.R.T. test

S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) test can detect and report irregularities in your hard drives. Schedule regular tests so that you can replace or repair them in time, and protect your DiskStation from unexpected hard drive failure.

Traffic Control

Schedule, prioritize or designate speed limits for users and groups. Reserve network bandwidth for certain DSM services, and apply limits to others.

SNMP

Support for Simple Network Management Protocol (SNMP) allows you to efficiently monitor connected DiskStations using a network management system (NMS). Download

Notifications

Choose what you wish to be notified of from more than 60 types of events. Many mechanisms are available: desktop notification, SMS, Email, as well as Push Notification on your mobile devices.

Additional security

UPS

Always have a backup power supply ready in case of a blackout. Set up a local, network, or SNMP UPS (Uninterruptible Power Supply) device to serve a specific DiskStation or any server in the network.

Securely erasing hard drives

Sometimes deleting files is simply not enough. Before you dispose of old hard drives, DSM can help you overwrite all their data with only a few clicks, eliminating any possibility of data theft.

Synology Central Management System (CMS)

Single-pane-of-glass management for all NAS servers

DSM has streamlined NAS management to the simplest form possible, but managing multiple DiskStations is still tedious work. With CMS, you can easily manage multiple Synology products by automating tasks and setting up policies to apply settings to groups of servers, thus reducing the marginal cost of maintenance to the minimum. A single dashboard provides access to relevant information and settings of all DiskStations, so abnormal behavior is promptly noticed.

Centralized monitoring

The system status, disk health, storage usage, logs as well as real-time resource consumption of your entire fleet of DiskStations are consolidated into a single console. This makes it easy for IT personnel to pinpoint where a problem originates as well as identify bottlenecks and plan for future system upgrades.

Centralized configuration

A distributed enterprise may set up servers for each of its offices. With CMS, you can define precise policies to be applied to server groups. When a NAS joins a group, it automatically adopts its rules and becomes properly configured, without requiring you to tweak the settings one by one. Packages on individual servers are also accessible from the central interface, giving you the flexibility to fine-tune them afterwards.

Centralized notification & updates

CMS aggregates notifications coming from each NAS to the host server. You can select whether and how you wish to be notified for more than 90 types of events, ranging from hardware malfunctions to insufficient storage space or cancelled tasks. DSM and package updates can be installed from the same portal as well - in one click, for all the servers you own.
