Re: small i & power systems (disk performance)

running our end of month processing.

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 :)
