Synology RackStation RS2821RP+ NAS/storage server Rack (3U) AMD Ryzen V1500B 4 GB DDR4 DiskStation Manager Black

Versatile and scalable storage
Synology RS2821RP+ is a 3U 16-bay storage server designed to accommodate a diverse set of business requirements. Scalable to 28 drives, the unit provides powerful backup and restoration functionality for the SMB sector. It delivers 2,200 MB/s sequential read and 105K 4K random read performance, and can be upgraded with SSD cache and 10/25Gb Ethernet options.

High performance storage for anything
Over 105K/59K random read/write IOPS and up to 2,220/1,164 MB/s sequential read/write throughput ensure ample performance for demanding workloads.

Built for reliability
Redundant power
Reduce the possibility of power disruptions on a single distribution channel or PDU adversely impacting data and service availability.

Near-zero downtime
Pair two identical devices with Synology High Availability and enable automatic minute-level failover between both devices in the event one server fails.

Data integrity and protection
ECC memory prevents data corruption, while the Btrfs file system brings higher reliability, snapshot technology, and simplified data protection.

Customize to suit
Easily adapt the RS2821RP+ to any business environment by adding faster networking, local SSD cache, or storage capacity.

10/25GbE ready
Support for 10/25GbE NICs lets you boost server throughput up to five times using Link Aggregation (bonding).

SSD cache
Boost read/write IOPS over HDD-only arrays by up to 16 times or more with NVMe or SATA SSD Cache

Serving remote workforces
Keep your remote workforce connected with powerful out-of-the-box solutions for collaboration, file sharing, and communication.

Synology Office
Create documents, spreadsheets, and slides in a multi-user environment. Real-time collaboration and automatic saving make remote work sessions a breeze.

Synology Chat
Chat and collaborate with colleagues using secure end-to-end encryption on with mobile, desktop, and browser clients.

Storage for virtualization
DSM streamlines provisioning for and management of virtual machines with full certification for VMware vSphere, Microsoft Hyper-V, Citrix XenServer, and OpenStack virtualization environments.
Synology Storage Console for VMware or Windows platforms lets you manage storage directly from your hypervisor. VMware VAAI integration and Windows ODX help offload storage operations and speed up data transfer.
