I have a functioning HP MSA1000 SAN. It currenlty has 14 - 300 GB SCSI U320 drives filling the drive cabinet. This is a Fibre channel SAN with a built in switch.
I would like to expand this SAN to increase my storage capacity. Since my inital cabinet is full, I will need to purchase and expansion cabinet. I would like to know if I have to stick with SCSI U320 drives in this expansion cabinet or is the any way to use SAS drives in this SAN. I would also like some details on cabling required to attach the new cabinet to the existing SAN and HP model numbers for the expansion cabinet.
