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 figure 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
