Synology RS2821RP+ 3U Rack 16 Bay Diskless NAS with Redundant Power

Synology RS2821RP+ 3U Rack 16 Bay Diskless NAS with Redundant Power

High-performance, general purpose storage solution for small to medium sized businesses.

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*1, and can be upgraded with SSD cache and 10/25Gb Ethernet*2 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.*1

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 brings higher system reliability, while the Btrfs file system helps prevent data corruption, supports snapshot technology, and simplifies data protection.

Customize to suit

Easily adapt RS2821RP+ to any business environment by adding faster networking, local SSD cache, or storage capacity.*2

10/25GbE ready - Support for 10/25GbE NICs lets you boost maximum network throughput using Link Aggregation (bonding).

SSD cache*3 - Boost read/write IOPS over HDD-only arrays by up to 16 times or more with NVMe or SATA SSD Cache

Storage expansion - Expand to 24 drive bays with a RX1217(RP) expansion unit

Back up your NAS to other devices

Hyper Backup - Back up files, iSCSI LUNs, installed applications, and system configurations to destinations including Synology C2 Storage, public cloud platforms, USB devices, file servers, local folders, or other Synology NAS.
Set and forget backup tasks with regular schedules, enhance security with fine-grained user permissions and encryption, keep backup sizes small with built-in deduplication*4, and restore data flexibly with multi-versioning.

Snapshot Replication - Snapshot Replication enables flexible point-in-time snapshots of shared folders and virtual machines with an RPO as low as 5 minutes and recovery within seconds.

Consolidate backups to your NAS

Active Backup Suite - Securely back up Windows clients and servers, Microsoft 365 and Google Workspace accounts, file servers, and VMware and Hyper-V virtual machines with the Active Backup Suite.
Leverage built-in deduplication*4 technology to reduce backup sizes and multi-versioning to allow flexible restoration.

Serving remote workforces

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

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.
