10 Hot-swappable SCSI Hard Disk Drives:

Installing/Hot Swapping

Hot-docking Bays

Two 3.5-inch hot-docking bays provide space for 3.5-inch wide by 1-inch high single connector
attachment (SCA) SCSI hard disk drives. You can install up to 2 industry-standard wide/fast-20
SCSI III SCA-type hard disk drives in these bays.
The power supply fans provide cooling for the hot swap drives. A system with two power supplies
is capable of cooling most drives that would be installed into the system, however drives which
dissipate a large amount of power may require three power supplies to be installed into the system
to insure proper cooling. Refer to the product specifications to determine if the particular drive to
be installed needs the additional cooling provided by a third power supply.
Carriers for 3.5-inch wide 1-inch or 1.6-inch height drives allow easy hot-swapping of drives in
and out of these bays without shutting down the server.
By installing a Redundant Array of Inexpensive Disks (RAID) controller board on the PHP I/O
baseboard, RAID software, and SCSI hard disk drives in the hot-docking bays, you can easily set
up RAID applications.

Equipment Log
