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.

All-in-one server
With just one RS815+/-‹RS815RP+, it's possible to handle a vast amount of tasks. RS815+/-‹RS815RP+ 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 RS815+/-‹RS815RP+ act as a VPN server to access company’s resources remotely, and more.

Ensuring business continuity
Uninterrupted availability is a critical goal for all businesses. RS815+/-‹RS815RP+ 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, RS815+/-‹RS815RP+ also ensures redundancy in the event of unexpected network failure.

Powerful backup solutions to enhance efficiency
Backup & Replication feature allows you to back up data from one RS815+/-‹RS815RP+ to another DiskStation, or rsync-compatible servers. It also provides the flexibility to restore the server to any particular point in time, and back up modified blocks to optimize storage and processing time. In addition, RS815+/-‹RS815RP+ offers you the capability to back up iSCSI LUNs with no extra charge.
