Synology RackStation RS3621xs+ SPECIFICATIONS

Reliability first

Service continuity is at the core of the Synology RackStation RS3621xs+ 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
