Protecting your company's assets
The Synology RS3621RPxs is an efficient 12-disk storage server. Its six-core processor allows you to run services that require intensive computing power, while the redundant power supply, ECC memory and the Btrfs file system ensure the protection of vital data. Based on 189,098 4K random read IOPS and 4718 MB/s sequential read speed1, it is an ideal choice for small businesses.

Redundant power supply
The two power supplies provide protection against power supply failure and accidental unplugging of the power cord, while hot-swappable fans can be replaced without shutting down the system.

Close to zero downtime
By pairing two identically designed units, Synology High Availability (SHA) creates an active-passive cluster with failover in minutes.

A new generation of file system
The Btrfs file system uses advanced storage technologies and optimized snapshots to prevent data loss and reduce maintenance costs.

10 GbE compatible
Support for 10 GbE network adapters increases the transmission speed of the unit up to five times using link aggregation (Link Aggregation).

SSD cache
You can increase read/write IOPS up to 16x by enabling SSD cache, using Synology M.2 NVMe adapter cards and SNV3000 series SSD units, or installing one or more 2.5-inch SAT5200 SSD units.

Disk spaces on demand
With minimal intervention, the capacity can be increased to 36 disk slots with two RX1217(RP) expansion units.

Storage for virtualization
Synology iSCSI storage supports popular virtualization solutions, so you can work efficiently with this easy-to-use interface. VMware vSphere 6.5 and VAAI integration help offload storage operations. The Windows Offloaded Data Transfer (ODX) function speeds up data transfer. With OpenStack Cinder support, you can turn your Synology NAS device into a block-based storage component. In addition, Synology Storage Console enables even more simplified storage provisioning and management settings in VMware and Windows environments.
