RackStation RS815+/RS815RP+
High-performance NAS server optimized for intensive tasks and encryption

Features:

Quad-core CPU brings high performance

Powered by a quad-core CPU running at 2.4 GHz, RS815+/RS815RP+ delivers average 389.03 MB/s reading and 361.33 MB/s writing.1 With this superior performance and a RAM module expandable to 6GB (2GB by default), RS815+/RS815RP+ is a powerful 1U NAS server for mission-critical tasks of SMBs.

Ideal encrypted data transmission with AES-NI

RS815+/RS815RP+ features a hardware encryption engine, which offloads encryption calculation tasks away from the main CPU. That means files and folders are encrypted on the fly without compromising the performance ─delivering encrypted data transmission speeds over 388.66 MB/s reading and 158.9 MB/s writing.

Robust scalability up to 8 drives

When your data storage is nearing its limits, RS815+/RS815RP+ can be connected to a dedicated RX415 expansion unit, letting you easily scale up to 8 drives for additional storage on the fly. With a RX415 connected through an eSATA cable with specially-designed locking connectors, raw capacity can be as high as 48TB.

Optimize storage management

With Synology's Storage Manager, RS815+/​RS815RP+ 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.

SSD cache technology

RS815+/RS815RP+ enables the combination of hard drives and SSD cache, boosting throughput efficiently while minimizing cost per gigabyte. With full SSD cache support, RS815+/RS815RP+ offers a significant reduction in I/O latency without crippling your budget. With only a small upfront investment, businesses can benefit from significant server performance enhancement.

Award winning OS - DiskStation Manager

Synology DiskStation Manager (DSM) is a sleek, browser-based operating system running on every DiskStation and RackStation, which makes managing your Synology NAS a breeze. Featuring an intuitive user interface, DSM makes accessing and sharing your data smarter and simpler. Synology's Package Center lets you download and install useful add-on packages designed specifically for individual or business needs, meaning you can enjoy more entertainment in your life or better productivity at work.

Fit into business environments easily

With the support of Windows AD, LDAP, and Domain Trust, RS815+/​RS815RP+ 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 RS815+/​RS815RP+ allows IT administrators to fine tune access controls and set up privileges to files and folders on RS815+/​RS815RP+ through the familiar Windows user interface. With compatibility for major protocols, RS815+/​RS815RP+ can eliminate server configuration overhead and enhance IT administrators' efficiency.

Seamless storage solution for virtualization environments

RS815+/​RS815RP+ provides seamless storage solutions for virtualization environments, including VMware, Citrix, and Microsoft Hyper-V. With VMware vSphere® 5 & VAAI integration, RS815+/​RS815RP+ 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.

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.

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. Businesses can enjoy efficient backup performance with "Point-in-time copy" technology for data consistence and incremental backup to speed up processing time.

Increase business productivity with cloud solutions

With comprehensive cloud solutions, RS815+/​RS815RP+ 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.

Secure your data

RS815+/​RS815RP+ offers advanced security measures to protect you from potential security holes. Security Advisor analyzes system settings, password strength, network preferences and removes any possible malware. AppArmor blocks malicious programs from accessing unauthorised system resources. You can also customize the trust level in Package Center to avoid installing packages from untrusted sources, safeguarding your NAS from unknown or tampered files. In addition, RS815+/​RS815RP+ provides other security add-ons, such as AES encryption, 2-Step verification, IP block & allow list, Antivirus packages, firewall, and DoS attack prevention.
