Introducing the SAS Expander

SAS expander expands one SAS address to a number of additional ports. It is an optimal

device for usage in data centers.

The CHENBRO SAS Expander Backplane provides high performance, 24 x 2.5” disk drives

connectivity and flexibility in RM235/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

SAS and SATA transfer rate at 6.0 Gb/s or 3 Gb/s with individual configurations.

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

described in the SAS standard.
