With the support of Windows AD, LDAP, and Domain Trust, DS1815+ enables seamless account integration. The User Home feature can automatically create a "home" folder for every user account to minimize the administrator's effort in repeatedly creating "home" folders for all accounts. Windows ACL support on DS1815+ allows IT administrators to fine tune access controls and set up privileges to files and folders on DS1815+ through the familiar Windows user interface. With compatibility for major protocols, DS1815+ can eliminate server configuration overhead and enhance IT administrators’ efficiency.

Fit into business environments easily

Seamless storage solution for virtualization environments

DS1815+ provides seamless storage solutions for virtualization environments, including VMware, Citrix, and Microsoft Hyper-V. With VMware vSphere® 5 & VAAI integration, DS1815+ helps offload specific storage operations and optimizes computation power in VMware environments. Windows ODX support speeds up data manipulation as the data transfer is offloaded. iSCSI also lets SMB users consolidate storage into data center storage arrays while providing hosts with the illusion of locally-attached disks.

Seamless storage solution

Synology CMS (Central Management System)

For enterprises with more than one Synology NAS server, CMS offers the flexibility and convenience for IT administrators to manage all of them from a single point of entry. Through a simple interface, you can obtain a clear overview on resource consumption and logs, helping you identify any issue right away. With group policies, CMS can do much more for your daily tasks. Once a NAS joins a group, it will automatically adopt its rules and behave as intended, without extra configuration.

Synology CMS

Optimize storage management

With Synology's Storage Manager, DS1815+ allows for flexible storage deployment and utilization. You can optimize RAID configuration with Synology Hybrid RAID (SHR) while providing redundant data protection. Other features such as multiple volumes on single RAID and Global Hot Spare also greatly enhance management efficiency and fit deployment of any kind.

Optimize storage management

All-in-one server

With just one DS1815+, it's possible to handle a vast amount of tasks. DS1815+ helps your company gain a competitive edge by acting as your multi-function server. Directory Server provides LDAP service, while DNS and DHCP packages allow you to host a domain name server and automate network IP assignment at no extra cost. With Synology's Proxy Server, you can regulate content access and monitor who can access which website while saving bandwidth. You can host up to 30 websites with Web Station, safeguard the office environments with Surveillance Station, send and receive mails using your own email domain with Mail Station, share printing capability with Printer Server, make DS1815+ act as a VPN server to access company’s resources remotely, and more.

All-in-one Server

Ensuring business continuity

Uninterrupted availability is a critical goal for all businesses. DS1815+ supports Synology High Availability (SHA) technology which combines an active and passive server into one cluster, the former always mirrored to the latter. The Heartbeat mechanism detects regular "heartbeats" between the two servers. If the main server encounters unexpected downtime, the passive server immediately takes over. With multiple LAN ports, DS1815+ also ensures redundancy in the event of unexpected network failure.

Ensuring business continuity

Effective backup solution

Synology DS1815+ can serve as a centralized backup target. Whether you are a Windows or Mac user, you can back up everything on your computer directly to Synology NAS using Cloud Station. Whenever you modify a file, the changes are backed up to DS1815+ automatically. Mac users also enjoy native Apple® Time Machine support. You can also back up data from your DS1815+ to another DiskStation, rsync servers, external drives, or even Amazon® S3, Glacier cloud service, Microsoft Azure, SFR, and hicloud. "Backup & Replication" allows you to schedule backup tasks and restore the server to any particular point in time, while minimizing storage consumption and processing time by saving only the specific data block that has been changed between versions.

Powerful Backup Solutions

Increase business productivity with cloud solutions

With comprehensive cloud solutions, DS1815+ lets you create your own private cloud easily. Cloud Station is the perfect package to sync files across multiple devices. Files can be edited in offline mode and later synced to Cloud Station, which keeps up to 32 historical versions, allowing you to restore a file back to previous version or recover deleted files. With the mobile app DS cloud, any change made to a file is automatically synced to your smartphones and tablets. For distributed enterprises, Synology's 2-way sync between different DiskStations ensures employees at different locations share the same information in real-time. IT administrators can handpick individual folders that they want to sync to different devices, manually or automatically based on file format and size. Folders synced by Cloud Station can be encrypted on DSM — no one will be able to access its content without your private key.

Increase business productivity with cloud solutions
