NAS Synology RackStation RS1221RP+

The Synology RackStation RS1221RP+ is a compact 2U rack-mounted NAS designed for small and medium businesses that require reliable, high-performance storage in space-constrained environments. Powered by a Ryzen Embedded V1500B processor and 4 GB DDR4 memory, it delivers strong sequential throughput and high random IOPS for data-intensive workloads. The RS1221RP+ model includes redundant power supplies for increased availability and supports expansion with RX418 units to grow capacity up to 12 drives.

Advantages

The RS1221RP+ combines a shallow-depth chassis with enterprise-grade features: redundant power supplies reduce the risk of outages, ECC memory and the Btrfs file system improve data integrity, and Synology High Availability provides automatic failover when paired with a second unit. The system supports SSD caching and 10GbE connectivity options to boost I/O performance and can be expanded with RX418 expansion units for additional drive bays. DiskStation Manager delivers integrated data protection apps such as Hyper Backup, Snapshot Replication and the Active Backup suite for comprehensive backup and recovery.

Suitable for

• Small and medium business file storage and sharing
• Backup and disaster recovery targets (Hyper Backup, Snapshot Replication)
• Virtualization storage for VMware/Hyper‑V and OpenStack Cinder
• Centralized office backup with Active Backup for Business
• Multi‑site high-availability clustering

How to use

Install the RS1221RP+ into a compatible shallow-depth 2-post or standard rack and connect network and power. Configure storage volumes and RAID arrays using Synology DiskStation Manager, enable ECC and Btrfs features for data integrity, and set up backup tasks with Hyper Backup or Snapshot Replication. For higher availability, pair two identical units and enable Synology High Availability to allow automatic failover. Optionally install NVMe or SATA SSDs for caching and add a RX418 expansion unit if additional drive bays are needed.

Recommendations

Use redundant power distribution and UPS protection to maximize uptime; schedule regular snapshots and off-site backups via Hyper Backup or cloud destinations; enable SSD cache and 10GbE connectivity where higher I/O and lower latency are required.
