IBM System p5 520 and 520Q Technical Overview and Introduction
Table 1-6 Hot-swappable disk drive options
You can install any combination of the following DVD-ROM and DVD-RAM drives in the two
slim-line bays:
򐂰 DVD-RAM drive, FC 1993
򐂰 DVD-ROM drive, FC 1994
A logical partition running a supported release of Linux requires a DVD-ROM drive or
DVD-RAM drive to provide a way to run the diagnostics CD for hardware diagnostics.
Concurrent diagnostics, as provided by the AIX 5L
diag command, are not available on the
Linux operating system at the time of writing.
You can install supplementary devices in the half-height media bay, such as:
򐂰
Internal 4 mm 36/72 GB LVD tape drive, FC 1991
򐂰
IBM 80/160 GB internal tape drive VXA, FC 1992
򐂰
IBM 160/320 GB internal tape drive with VXA-3 technology, FC 1892
򐂰
IBM 200/400 GB LTO2 tape drive, FC 1997
DVD devices installed in the slim-line bays must be assigned as a group to a single LPAR on
a partitioned system.
A dual-channel RAID enablement daughter card is also available (FC 1907).
1.3.4 USB diskette drive
The externally attached USB diskette drive provides storage capacity up to 1.44 MB
(FC 2591) on high-density (2HD) floppy disks and 720 KB on a double density floppy disk. It
includes a 350 mm (13.7 in.) cable with standard USB connector. This super slim-line and
lightweight USB V2-attached diskette drive takes its power requirements from the USB port.
The drive can be attached to the integrated USB ports or to a USB adapter (FC 2738). A
maximum of one USB diskette drive is supported per integrated controller/adapter. The same
controller can share a USB mouse and keyboard.
1.3.5 I/O drawers
The p5-520 and p5-520Q have six internal PCI-X slots — three long slots and three short
slots. If you need more PCI-X slots to extend the number of LPARs and partitions, you can
connect up to four 7311 Model D20 drawers to the optional RIO-2 ports (FC 2888) that are
provided on the rear of the system in a minimum configuration.
The 7311 Model D20 I/O drawer is a 4U full-size drawer, which must be mounted in a rack. It
features seven hot-pluggable PCI-X slots and, optionally, up to 12 hot-swappable disks
arranged in two 6-packs. Redundant, concurrently maintainable power and cooling is an
optional feature (FC 6268). The 7311 Model D20 I/O drawer offers a modular growth path for
a system with increasing I/O requirements. When a p5-520 or p5-520Q is fully configured with
