Expansion Unit RXD1215sas

Reliable, scalable SAS storage expansion unit

Features
Specs

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.

Notes:

Two RC18015xs+ and at least one RXD1215sas expansion unit are required to configure and operate. Additional RXD1215sas Expansion Units can be purchased separately.
Raw storage capacity varies depending on hard drive model and individual settings. Hard drives are purchased separately. Learn more about the compatibility of hard drives, please click here.

Notes:

Model specifications are subject to change without prior notice.
The figures are based on Synology internal testing. Each performance test is done individually. No other services or applications are processed at the same time.
The actual performance may be lower than lab testing figure due to differences in server configuration, deployment, and the number of active operations.
If usage requirements exceed the specifications above, please contact our regional partners for professional advice.
