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
– Fits into shallow rackmount enclosures
– Easy-to-install on 2-post racks
BULIT 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
– 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
