Short Description

The Synology RX1223RP is a 12-bay rackmount expansion unit designed for compatible Synology storage systems that need significantly more capacity without replacing the host server.

With hot-swappable bays, online expansion and redundant power, it provides a business-focused route to increasing storage while maintaining availability.

Why Choose This Synology

Add 12 Bays at a Time

Each RX1223RP adds twelve additional SATA drive bays, making it well suited to organisations managing rapidly growing storage requirements.

Expand Without Interrupting Services

Synology's online storage expansion allows supported volumes to be expanded or new volumes created without shutting down normal host services.

Redundant Power for Better Availability

Dual power supplies help keep the expansion unit online if one PSU or power source fails.

Built for Easier Maintenance

Hot-swappable drive trays and replaceable system fans help reduce the impact of routine hardware maintenance.

Managed from the Host NAS

The RX1223RP integrates with Synology DSM, so storage management remains centralised rather than introducing another independent system.

Best For

• High-capacity business storage
• Compatible RS2423 Series RackStations
• Synology SA6400 environments
• Growing backup repositories
• Surveillance storage
• Large shared data sets
• Businesses requiring redundant power
• Enterprise storage expansion

Product Description

The Synology RX1223RP provides twelve additional drive bays for compatible Synology storage systems.

It supports compatible 3.5-inch SATA HDDs and 2.5-inch SATA SSDs, with hot-swappable bays allowing drive replacement without powering down the system.

A Mini-SAS HD expansion connection links the unit to the compatible host system, while Synology DSM provides centralised RAID and storage management.

Redundant 550W power supplies help reduce the risk of storage interruption caused by a single PSU failure.

For supported high-capacity systems, multiple RX1223RP units can be deployed to create very large-scale storage configurations.

The RX1223RP requires a compatible Synology host system and compatible storage drives.
