Dependable storage for many scenarios

Synology NAS is a versatile storage platform that fits perfectly in file server, block storage, or application server roles that require high availability, reliability, and leading-edge storage technology.

Multi-purpose NAS storage
Keep digital assets accessible locally or remotely with easy-to-maintain shared file storage, backed by fast SMB file serving, powerful RAID options, efficient backup tools, and granular permission management.

SAN infrastructure for SMBs
Deploy certified block storage with minimal disruption thanks to easy management plugins, and leverage free snapshots paired with built-in high-availability options to maximize service availability.

Versatile business applications
Host business solutions privately and on your own terms, including a powerful backup server to protect all business assets from a centralized platform or a full-fledged surveillance platform to safeguard physical premises with transparent licensing.


Built to maximize uptime

The DS3622xs+ is built to keep mission-critical data and services accessible, so that businesses can continue to perform even when disaster strikes.

Out-of-band (OOB) management
Simplify troubleshooting by managing powered-down devices remotely and accessing critical logs through a dedicated interface.

High-availability solution
Create an active-passive cluster with minute-level failover by pairing the DS3622xs+ with an identical unit using Synology High Availability.

Rise to the challenge

Prepare your DS3622xs+ for the heaviest workloads or upgrade flexibly as your business continues to grow. Use add-in cards to add bandwidth, fast SSD cache, or both.

Maximize bandwidth
Handle heavier I/O and serve more users with dual-port Synology 10 or 25GbE network interface cards. Integrate with any FC SAN using compatible Fibre Channel adapters.

Accelerate storage performance
Enable SSD caching to speed up HDD arrays with an M.2 NVMe SSD adapter card and SNV3000 series SSDs, or install SAT5200 SATA SSDs in drive bays to increase performance.

Do both with one card
Add both 10GbE connectivity and M.2 NVMe SSD slots for SSD cache with a single combination NIC and adapter card.

Out-of-the-box data protection

Protect your data with professional backup software for your Synology NAS, other devices, and applications.
