INTRODUCTION

Note:

It is rare for both Fibre/SAS/iSCSI to 6Gb/s SAS RAID

subsystem to fail simultaneously. However, if this occurs, the

RAID subsystem can not issue critical or non-critical event

alarms for any subsystem component.

1.5 Expansion Connection

The Fibre/SAS/iSCSI to 6Gb/s SAS RAID subsystem is a device

that contains one expander port. Expander port may support be-

ing attached to SAS initiator ports, SAS and/or SATA target ports,

and to other expander ports. The Fibre/SAS/iSCSI to 6Gb/s SAS

RAID subsystem can connect up to 7 expander enclosures to the

host system. The maximum drive no. is 122 through this RAID

subsystem with 7 expander enclosures. Enclosures installed with

SAS disks or SATA disks can be included in the same dasiy-chain.

The following gure shows how to connect the external Mini SAS

cable from the Fibre/SAS/iSCSI to 6Gb/s SAS RAID subsystem

to the external SAS JBOD enclosure. Daisy-chains longer than

the limitation of subsystems are not supported even if it may be

workable.
