Introduction
About this Guide
The SAS expander backplane user’s manual provides the information for functions,
capabilities, configuring and assembly / disassembly of this backplane.
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.
