Synology Rackstation RS1221RP+
 
Overview
A powerful storage solution for businesses and IT enthusiasts with redundancy 
and service continuity features.
Compact and reliable
The RS1221+/RS1221RP+, at only 30 to 38 centimeters deep, is built for 
space-sensitive deployments. Boasting over 100K 4K random read IOPS and 2,315 
MB/s sequential read1, the RS1221+/RS1221RP+ is equipped to handle heavy 
workloads in data-intensive environments. The RS1221RP+ additionally features an 
extra level of protection with redundant power supplies.
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.
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.
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.




Fully certified storage virtualization 
solutions
Synology iSCSI storage fully supports mainstream virtualization solutions to 
enhance work efficiency with an easy management interface. VMware vSphere 6 and 
VAAI integration helps offload storage operations. Windows Offloaded Data 
Transfer (ODX) speeds up data transfer. OpenStack Cinder support turns your 
Synology NAS into a block-based storage component. Additionally Synology Storage 
Console enables even more simplified storage provisioning and management options 
in VMware and Windows environments.

Works best with Synology drives
Engineered to handle intensive 24/7 workloads, Synology drives consistently 
deliver top-grade performance.
