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.

Backplane

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

SAS and SATA transfer rate at 6.0 Gbit/s or 3 Gbit/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.

Features

General

• To expand one Mini-SAS port (SFF-8087) to 24 x SATAII/SAS 3.5” HDD

• Support HDD Failure / Activity Indication and HDD ID Mapping

• Support RM418/RM417 only

High-Speed I/O

• 6.0 Gbit/s or 3.0 Gbit/s operations

• Automatic negotiation of linking speed

Application

• SAS / SATA HDD NAS storage sever or enclosure

• Security system

• Video streaming / editing workstation

SAS expander Backplane must be used only with SAS RAID card

The supported HDD quantity is depended on the capability of the

SAS RAID card in the system.
