A small number of systems have a duplex board preinstalled. The duplex board
supports dual-bus mass storage configurations. Duplex hot-swap drive
configurations and SCSI IDs are later in this chapter.
If you are installing the duplex board, refer to the HP NetServer Duplex Kit
Installation Guide that came with the Duplex Board Accessory Kit for other
Mass Storage Guidelines

Selecting SCSI Devices
Hot-swap mass storage comprises either a low profile (1-inch) or half-height
(1.6-inch) drive in a tray. This is called a module. For the hot-swap shelves use
HP Ultra-2 (LVD) or Ultra-3 SCSI 3.5-inch hard disk drives. HP hot-swap drives
are set for LVD SCSI operation and without device ID or termination. Do not
change these settings.
A half-height drive takes most of two slots. You must use a
drive spacer to close up the remaining space.
For the non-hot swap shelves, use 3.5-inch or 5.25-inch single-ended (SE) SCSI
devices. This bay supports either two half-height or three low-profile devices. You
can order HP mounting kits for removable media devices or trays for 3.5-inch
hard disk drives (both low-profile and half-height). You may use narrow/wide
SCSI adapters on these devices.
