HARDWARE INSTALLATION

In the backplane solution, SAS/SATA drives are directly connected

to 6Gb/s SAS system backplane or through an expander board.

The number of SAS/SATA drives is limited to the number of slots

available on the backplane. Some backplanes support daisy chain

expansion to the next backplanes. The 6Gb/s SAS RAID controller

can support daisy-chain up to 8 enclosures. The maximum drive

no. is 128 devices through 8 enclosures. The following gure shows

how to connect the external Min SAS cable from the 6Gb/s SAS

RAID controller that has external connectors to the external drive

boxes or drive enclosures.

The following table is the max no. of 6Gb/s SAS RAID controller

supported:
