Peripheral Drive Bays
3.5-inch User Accessible Diskette Drive Bay
The 3.5-inch diskette drive in the vertical 3.5-inch peripheral bay supports
720 KB and 1.44 MB media.
5.25-inch User Accessible Drive Bays
Three 5.25-inch half-height bays provide space for removable media devices
such as tape drives and CD-ROM drives. You can convert any two adjacent
5.25-inch bays to a single full-height bay. We recommend that you do not
use these bays for hard disk drives because they generate EMI, and ESD
susceptibility increases.
3.5-inch Hot-docking Drive Bays
Using industry standard 80-pin SCA connectors, the hot-docking backplane
in the upper bay supports up to five industry standard SCA hard disk
drives. The hot-docking bays accept peripherals that consume up to 11
watts of power and run at a maximum ambient temperature of 55 °C.
You can install an additional hot-docking backplane in the lower
hot-docking bay for five more drives. However, if you do, you must install
an additional power supply in the chassis to support drives in the lower
bay. The upper and lower hot-docking bays, when fully configured with 10
4 GB hard disk drives, provide over 40 GB of hard disk drive space.
The plastic front door on the front of the server covers a removable metal
door. Two spring-loaded captive screws secure the metal door to the
chassis. These doors provide proper air-flow and easy access to the drives
in the upper and lower hot-docking bays. Plastic drive carriers for 3.5-inch
wide by 1-inch high drives allow easy hot swapping of these drives without
shutting down the server.
With the RPX board installed on the system board, RAID software, and
SCSI hard disk drives in the hot-docking bays, you can easily set up RAID
applications.
