Dell MD1000 Daisy Chaining SATA and SAS
Posted on 2009-05-10
Our current environment has a dell 2950 connected to 2 MD1000 shelves via a PERC5/E.
One MD1000 (SATA) is plugged into port 0 and one into port 1 (SATA), both operating in unified mode.
I have been asked to provide more storage space on the array(s) as current capacity has been reached.
My question is this:
Is it possible to add a third MD1000 but with SAS drives? In effect a SAS shelf daisy chained under a SATA shelf which is connected to the raid card?
I understand that each loop can control upto 3 units but am unsure regarding mixing SATA and SAS shelves.
Simple question I know but I cant seem to get a firm answer on this.
