Hot-swap Hard Disk Drive and Peripheral Device Bays
The hard disk drive and peripheral device bays can accommodate the following devices:
Ten 1-inch hot-swap Ultra320 SCSI hard disk drives
One ½-inch optical drive (installed with base system)
Two half-height or one full-height 5¼-inch SCSI tape device
Note:
Cooling and EMI constraints do not allow installation of an IDE hard disk drive in
the tape device bay.
The SCSI Backplane Board supports Low Voltage Differential (LVD) SCSI drives only.
Single-ended (SE) devices are supported off the secondary external SCSI channel on the
Server Board Set SE8500HW4 Mainboard. SE devices are not supported in the hot-swap
hard disk drive bays in the front of the system, or validated by Intel.
The optical drive and SCSI tape device(s) are not hot-swap devices. System power must be
turned off when installing or removing these drives.
Because hard disk drives have different cooling, power, and vibration characteristics, Intel
will validate specific hard disk drive types in the Server Platform SR6850HW4. See the Intel
Server Board Set SE8500HW4 Tested Hardware and Operating System List
for the qualified
drives.
The hard disk drive carriers supplied with the system accommodate 3½-inch x 1-inch SCSI
hard disk drives. The hard disk drive is attached to the carrier with four Phillips*-head
screws. The carrier is retained in the chassis by a locking handle.
The SCSI Backplane Board contains a dual color LED for each hard drive to display status.
The LED signal is transmitted to the front of the system via a light pipe integrated in the hard
drive carrier.
Due to the required cable length and bus performance, the Server Board Set SE8500HW4
Mainboard contains a Serial ATA (SATA) connecter instead of a Parallel ATA (PATA)
connector. The optical drive connects to the SATA-to-IDE Converter Board, which converts
the SATA signal to an IDE signal for the 1/2-inch optical drive. The optical drive is installed
in a sheet metal bracket and then installed in the Server Platform SR6850HW4.
See Chapter 7 for a description of the SCSI Backplane Board. See Chapter 9 for
descriptions of the SATA-to-IDE Converter Board.
