Hi Guys,

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.

Cheers.

For those interested, yes it is fully supported to use SATA and SAS so long as they are in their own shelf. ie. SATA in one shelf and SAS in the other.

To get best performance place the SAS shelf at the top of the loop with slower drives below.

Cheers.
