Synology Rack Station 12-Bay Rack Mount Expansion Unit (RXD1215sas)

The Synology RXD1215sas is a 12-bay rack mount expansion unit designed specifically for the Synology RC18015xs+ high availability cluster. It functions as a shared storage pool between the two computing nodes in the cluster, eliminating the need for data replication across nodes. This design significantly reduces energy consumption and optimizes rack space by consolidating storage resources into a centralized unit.

Equipped with snapshot SSD cache support, the RXD1215sas enhances data protection by enabling efficient point-in-time copies of data. This feature is crucial for maintaining data integrity and facilitating quick recovery in case of accidental deletion or corruption. The unit supports scalability by allowing multiple RXD1215sas expansion units to be added to the HA cluster. Up to 15 such units can be integrated, enabling the system to scale up to a total of 180 hard disk drives.

With this configuration, the maximum raw storage capacity can exceed one petabyte, making it highly suitable for environments requiring large-scale data storage and high availability. The modular design ensures flexibility in expanding storage capacity as business needs evolve without disrupting existing operations.

The RXD1215sas is an essential component for organizations that prioritize both performance and scalability in their storage infrastructure. Its integration with the RC18015xs+ allows for efficient resource utilization while ensuring robust data protection through advanced features like snapshot caching and centralized storage pooling. Whether used in enterprise environments, media production, or data-intensive research, this expansion unit provides a reliable and future-proof solution for growing storage demands.
