Regarding the DL585 etc boxes from HP, they seem to require external JBOD or
SCSI/SAS enclosures.  Does anyone have any particular preference on how these
units should be configured or speced?  I'm guessing I'll use the onboard SCSI
RAID 1 with the onboard drives for the OS, but will need 2 external channels
for the data and xlog.  Any recommendations there?

Sincerely,
Kenji
