The CHENBRO SAS Expander Backplane provides high performance, 24 x 3.5” disk drives

connectivity and flexibility in RM418/RM417 . It is a valuable solution to other expansive

and complex topologies. The SAS expander is ideal for high availability, scalable server

clustering environments, front-end storage subsystems used in clusters, SANs and NAS

environments.

The CHENBRO SAS Expander Backplane is based on LSI SAS2 X36 IC that enables the

connection of 24 drives in directly attached SAS or SATA HDD. This Backplane performs

The SAS expander IC supports the Serial SCSI Protocol (SSP), SATA Tunneled Protocol

(STP) and Serial Management Protocol (SMP). Those are based on SAS protocol and
