Hot-plug SCSI hard drive options
When adding SCSI hard drives to the server, observe the following general
guidelines:
• Hot-plug hard drives must be Ultra320 SCSI drives for optimum
performance. Mixing Ultra320 SCSI drives other drive types degrades the
overall performance of the drive subsystem.
• When drives are groups together into the same drives array, drives must be
the same capacity to provide the greatest storage space efficiency.
Removing a hard drive blank
CAUTION: To prevent improper cooling and thermal damage, do
not operate the server unless all bays are populated with either a
component or a blank.
