Expansion Unit RXD1215sas

Reliable, scalable SAS storage expansion unit

Massive scalability up to 180 drives

Up to fifteen RXD1215sas can be connected to the dual RC18015xs+ computing nodes, accommodating massive scalability up to 180 drives and maximum raw storage beyond 1PB. The shared storage architecture eliminates the need for data replication over the network, in addition to drastically reducing deployment costs.

Hardware redundancy enhances system uptime

RXD1215sas is equipped with redundant hardware components, such as power supply units, SAS modules, and system cooling fans. In the event of component failure, the system continues operating normally while replacement parts are obtained and installed.
