    Intel® Xeon® D-1541 8-core 2.1 GHz


    Built-in dual-port 10GbE


    8 GB ECC DDR4 Up to 64 GB


    Up to 36 drive bays with RX1217(RP)

    Storage you can trust

    The RS3621xs+ keeps your data protected while you concentrate on delivering the best results to your customers - even when disaster strikes.

    Redundant power

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

    Maximize service availability

    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.

    Tailored to your business

    The RS3621xs+ includes two PCIe slots for performance, networking, and storage upgrades enabling it to adapt to any business environment.

    Double bandwidth

    Upgrade network bandwidth in minutes by 2x or more with Synology's range of 10GbE NICs.

    SSD cache

    Boost read/write IOPS by up to 16 times by enabling SSD cache with our Synology M.2 NVMe adapter cards and SNV3500 SSDs or by installing one or more 2.5" SAT5200 SSDs.

    Storage expansion

    Quickly and easily scale up to 36 drives with two RX1217(RP) expansion units.

    License-free data protection

    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.
