A compact design for space efficiency
The RS1221+ and its RX418 expansion units are designed to help you save space in compact deployments. At only 30 centimeters, half the length of a typical 2U unit, it fits perfectly snug onto 2-post or shallow rackmount enclosures. The RS1221RP+ with dual power supplies comes in at 38 cm, also fitting most shallow depth enclosures.
- Fits into shallow rackmount enclosures
- Easy-to-install on 2-post racks
Built for reliability
Redundant power
Reduce the chance that power disruptions on a single distribution channel or PDU causes data and service availability degradation.
Maximize service availability
When paired with another identical unit, Synology High Availability enables automatic minute-level failover between two clustered servers in the event of a server failure to minimize service downtime.Learn more
Data integrity and protection
ECC memory and the Btrfs file system bring higher reliability and snapshot capabilities to help prevent data corruption and simplify data protection.Learn more
High performance storage for anything
Up to 2,315/1,147 MB/s sequential read and write throughput and over 100K/54K random read/write IOPS ensures ample performance for demanding workloads.
