Setup Utility and the SCSI Select Utility. Refer to Chapter 8,
"Configuring the HP Netserver," for more information.
Installed Mass Storage Devices
Table 3-1 lists the number and types of mass storage devices that may be installed
in the HP Netserver LP 2000r.

Installed Devices
and Addresses
Flexible disk drive 1 Factory installed flexible disk drive
IDE-1 1* Factory installed CD-ROM drive
(Primary IDE connector)
Ultra-160M SCSI
Channel A up to 6 **
•
Up to 6 Hot Swap SCSI hard
disk drives (address = ID 0, 1,
2, 3, 4, 5)
•
Embedded SCSI controller
(address = ID 7)
Ultra-160M SCSI
Channel B up to 15 **
•
Control of up to 15 external
SCSI devices
* The primary IDE (IDE-1) cable is connected to the factory-installed CD-ROM drive. A
secondary IDE connector (IDE-2) is available on the system board, but not supported by
Hewlett-Packard.
** Both SCSI channels (A and B) can each support up to 15 devices; however, there are
only enough internal storage slots for six Hot Swap SCSI hard drives. Channel B is used to
control external SCSI devices, typically a SCSI tape backup device.
Hardware Mirroring
You may choose to mirror hard drives (RAID 1) in the HP Netserver’s hot swap
slots. Hardware mirroring can help speed up disk access time.
To mirror hard drives, you need to install the HP NetRAID Controller board and
use an additional SCSI cable to connect the NetRAID board to the SCSI
backplane connector. If you do not use HP’s NetRAID Controller board, be sure
to use a DAC with an LVD interface.
