Engineered to deliver high throughput and robust data protection, its 8-core processor and built-in dual 10GbE ports enable it to handle even the most demanding of workloads in modern business environments. DiskStation Manager (DSM) provides comprehensive software solutions covering file management, data protection, surveillance, collaboration, virtualization and more.

Built to Handle Intensive Workloads

Synology RackStation RS3621xs+ is built to deliver exceptional performance, flexibility, and scalability to meet the requirements of businesses.

  1. Up to 238,273 4K random read IOPS and 5,819 MB/s sequential read performance for demanding workloads
  2. Featuring 12 drive bays supporting both SATA HDD/SSD 2.5/3.5" drives, expandable to 36 bays using two Synology RX1217(RP) expansion units

Optimized for Data Protection and Integrity

Powered by Synology DSM, our unified data management operating system, and built upon the Btrfs file system, data stored on the RS3621xs+ is safely guarded by modern data protection technologies.

  1. Advanced snapshot technology provides schedulable and near-instantaneous data protection of shared folders and LUNs
  2. File and folder-level data restoration enables restoration of specific files or folders
  3. Flexible storage quota system helps admins effortlessly manage available space by specifying storage limits for shared folders
  4. File self-healing detects and recovers corrupted files using mirrored metadata and RAID configurations
  5. Inline compression compresses data before writing it to the drive, reducing write commands and optimizing storage space

Virtualization and Certified Storage

DSM streamlines the provisioning and management of storage for virtual machines (VM). Certified for VMware® vSphere™, Microsoft® Hyper-V®, Citrix® XenServer™, and OpenStack, it integrates with your virtualization platform of choice through iSCSI or NFS protocols. Install Synology Storage Console on VMware or Windows platforms for additional management convenience and functionality right in the hypervisor.

Synology Virtual Machine Manager (VMM) is a hosted hypervisor for virtual machines running Windows®, Linux®, or virtualized versions of DSM with recovery mechanisms that ensure data protection on each VM.
