Mass Storage Guidelines

· General Guidelines
o Use care when unpacking and handling the hard 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.
o Do not stack drives.
o The Server is internally limited to 6 mass storage shelves.
The flexible disk drive and CD-ROM drive, which are standard on all models of the HP Server
tc2110, occupy shelves 1 and 2 respectively. The first four mass storage shelves may also be referred
to as common trays, or drive trays. See Figure 3-5.
· IDE Devices
o The embedded IDE controller is an Enhanced-IDE dual channel controller and provides two
connectors (IDE-1 and IDE-2) for IDE devices.
Refer to "System Board Layout" in Chapter 9, "Specifications."
o The IDE CD-ROM uses one connector on the cable from the IDE-2 connector, leaving one
connector for an optional third hard drive or IDE device on the IDE model. The CD-ROM is
configured as the master device, unless a third HDD is installed, which should be configured as the
master device.
For the SCSI model the second IDE-2 connector could be used for any additional IDE device, such
as IDE hard drive.
o The primary IDE connector (IDE-1) and cable is used for the first or standard hard IDE drive and the
second optional hard drive, but this cable is not provided for the SCSI model.
The bundled IDE CD-ROM and hard disk drive were put on separate IDE connectors to improve
performance.
· SCSI Devices
o Use only low-voltage differential (LVD) SCSI devices.
o Do not use high voltage differential (HVD) SCSI devices in the Server or damage to the controller
and other devices may occur.
