Safeguard your business assets

Synology RS3621RPxs is a powerful 12-bay storage server. Its 6-core processor enables compute-intensive services while its redundant power, ECC memory, and Btrfs file system safeguard mission-critical data. Capable of delivering 189,098 4K random read IOPS and 4,718 MB/s sequential read throughput, it is ideal for small businesses.

Compute

Intel^® Xeon^® D-1531 6-core 2.2 GHz

Throughput

4,718 MB/s seq. read 189,098 4K random read IOPS¹

Expandability

Dual PCIe slots for 10GbE or NVMe cache

Scalability

Up to 36 drive bays with RX1217(RP)

Reliability first

Service continuity is at the core of the RS3621RPxs design.

Redundant power

Dual PSUs provide protection against a PSU failure or accidental cord removal while hot-swappable fans can be replaced without powering down the system.

Near-zero downtime

Synology High Availability (SHA) pairs two identical units together creating an active-passive cluster with minute-level failover.

Next-generation file system

Btrfs prevents data corruption and reduces maintenance overheads with advanced storage technologies and optimized snapshots.

Customize to suit

The two built-in PCIe slots allow users to customize the RS3621RPxs to satisfy unique performance, networking, and storage requirements.

10GbE ready

Support for 10GbE NICs expands the throughput of the unit by up to 5x times using link aggregation.
SSD cache

Boost read/write IOPS by up to 16 times by enabling SSD cache via our Synology M.2 NVMe adapter cards and SNV3000 Series SSDs or by installing one or more 2.5" SAT5200 SSDs.
On-demand drive bays

Expand to 36 drive bays using two RX1217(RP) expansion units with minimal intervention.

License-free backup solutions

Keep disaster at bay

Hyper Backup

A comprehensive backup and recovery solution for securing data stored on Synology servers. Backup data locally, to another Synology device, rsync server, or cloud-based storage such as Google Drive, Dropbox, S3-compatible destinations, and Synology C2. Deduplication, integrity checks, and incremental transfer technology reduce bandwidth and storage used.

Snapshot Replication

Easily schedule flexible point-in-time backups of shared folders and iSCSI LUNs with an RPO as low as 5 minutes and recovery in seconds. Set up replication and failover to other Synology storage systems for fast RTOs and minimal service disruption.

Active Backup Suite

Enables administrators to easily backup the entire IT infrastructure to their NAS, including Windows & Linux workstations and servers, file servers, VMware and Hyper-V virtual machines, and Microsoft 365 and Google Workspace accounts. Backups benefit from deduplication, multiversioning, and optimizations to reduce bandwidth and storage used.
