Mass Storage
The HP Server tc3100 comes standard with an IDE CD-ROM and a flexible disk drive with some
configuration of SCSI hard disk drives and an optional SCSI tape backup drive. The internal mass storage can
hold up to five SCSI hard drives with cabling provided.
This section describes how to install the internal mass storage devices, including the internal SCSI hot swap
hard drives and the optional tape backup (DAT) drive.
Guidelines
· General Guidelines
o Use care when unpacking and handling the 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 Do not use high voltage differential (HVD) SCSI devices on any of the SCSI channels or damage
will occur. Use only Single-Ended (SE) or Low-Voltage Differential (LVD) devices.
o The server is internally limited to 5 hard disk drives.
The flexible disk drive and CD-ROM drive, which are standard on all models of the HP Server
tc3100, occupy shelves 8 and 7 respectively. See Figure 3-5 and Figure 3-6.
o If a backup tape drive is used, it occupies shelf 6, leaving five 3.5-inch devices available for shelves
1-5, and at least one is required for the boot drive.
· IDE Devices
o The embedded IDE controller is an Enhanced-IDE single channel controller. Refer to "System Board
Layout" in Chapter 9, "Specifications."
o The IDE CD-ROM uses only one connector on the cable from the IDE channel (IDE2) connector.
· SCSI Device Selection
o Ensure the SCSI devices you install in both non-hot swap and hot swap-drive bays do not have
terminations installed. The non-hot swap SCSI drives are connected to a terminated cable and the hot
swap cage provides the termination for any unused slots in the cage.
o Use only HP LVD SCSI 3.5 inch hard disk drives for the cold swap and hot swap drive cages.
The HP cold swap and hot swap drives come set for LVD SCSI operation and without device ID or
termination. Do not change these settings.
o Use the supported 5.25 inch SCSI devices for the common tray (5.25") shelves.
The available space in the 5.25" common tray shelves supports two half-height (1.6 inch) devices.
You can order HP mounting kits for removable media devices. You may use narrow/wide SCSI
adapters on these devices.
o The embedded dual-channel Ultra-3 SCSI controller includes connectors for SCSI channels A
and B.
o Channel A can be used for internal tape backup or to connect to external mass storage devices or to
external backup tape devices. Channel A is connected to the optional internal tape drive.
An additional cable kit is required for external mass storage devices or connecting the optional tape
backup drive. Refer to the appropriate topic later in this chapter.
o Channel B typically is used for cabling the factory installed hard disk drives, which may consists of
five SCSI drives (including an optional tape drive). The standard SCSI cable has five 68-pin, high-
density connectors for the SCSI devices and has a terminator on the end of the cable.
