The M25 will support the 8 SAS drives in the CAC AND the additional 12 SAS
drives in the 12S expansion disk draw. It doesn't matter if you have one or
two processors turned on.
The M15 will only support the 8 SAS drives in the CEC.

The BP has collected performance data and suggested 12x 4327 in CEC and
5095 w/5583 (5777 w/cache). I've asked for more details on the analysis.
The 525 will only do 8 drives in the CEC (CPU) so I'm guessing that they
are suggesting 4 in the CEC with Raid5 and 8 in the 0595 or 2 mirrored
in the CEC and 10 in the 0595. either way the bulk of the disk space is
outside the CEC.
The M25 only uses SAS drives in the CEC and you need a dual core model
to support the SAS Expansion unit. You could do 4 SAS drives in the CEC
and 8 SCSI (4327s) in the 0595. In any case the drives and controllers
will way out perform you old stuff :)
