Introduction
This chapter provides information on mass storage, connector pin-outs, accessory guidelines and system
specifications.
Mass Storage
Mass Storage Guidelines
•
General
Guidelines
◊◊◊◊
Use care when unpacking and handling the SCSI disk drives.
◊◊◊◊
◊◊◊◊
The hard disk drives are very susceptible to mechanical shock and can be easily damaged
by a drop as short as one-quarter of an inch. If the drop would crack an egg, it will damage
the drive.
◊◊◊◊
Do not stack drives.
◊◊◊◊
The HP Server is internally limited to 2 mass storage devices.
•
IDE
Devices
◊◊◊◊
The IDE diskette drive and DVD drive are standard on all models of the HP Server. They
are housed in two piece drive carrier assemblies that rest on the chassis surface. They are
accessible when the top cover is removed. See Figures 4-3 and 4-4.
◊◊◊◊
The Legacy I/O board contains the PCI-enhanced IDE interface with two IDE buses. The
primary IDE 0 bus supports the IDE diskette drive and the secondary IDE 1 bus supports the
DVD drive.
◊◊◊◊
Refer to "System Board Layout" in Appendix A, "Specifications."
•
SCSI Device Selection
◊◊◊◊
A Qlogic ISP12160A Ultra3 SCSI chip is a highly integrated bus master, dual-channel SCSI
I/O processor for SCSI initiator and target applications. The chip supports dual channel,
Ultra3 (Ultra 160) SCSI functionality and is pin compatible with QLogic’s ISP12160 Ultra3
SCSI processor as well as QLogic’s ISP1280 dual SCSI processor.
◊◊◊◊
Use only low-voltage differential (LVD) SCSI devices.
◊◊◊◊
Do not use high voltage differential (HVD) devices on either of the SCSI channels or
damage will occur.
◊◊◊◊
The Ultra SCSI controller swupports dual channel Ultra3 functionality and is pin compatible
with Qlogic’s IPS12160 Ultra3 processor and Qlogic’s ISP1280 dual SCSI processor.
◊◊◊◊
Channel B may be used in a duplexing arrangement or to control an external mass storage
solution. At least two SCSI hard disk drives are required if the duplexing option is used.
