Using Ultra SCSI in your HP NetServer
Starting October 1996, HP began shipping Ultra SCSI capable disk drives. Ultra SCSI is a new
industry standard that allows for data transfer rates of up to 40 Mb per second. In order for Ultra
SCSI to work properly, all affected components (SCSI controller, cabling, disk drive, and SCSI
terminator) must be Ultra SCSI compliant. If any of these components are not Ultra SCSI
compatible, Ultra SCSI must be disabled for the SCSI channel, to avoid potential data corruption.
NOTE: The drives on a SCSI bus may be a mixture of Ultra SCSI capable and non Ultra SCSI
drives. The controller negotiates the bus mode with each drive, depending on the drive's individual
capabilities.
The following matrix shows the support of Ultra-SCSI in HPs current NetServers:
NetServer Platform Ultra SCSI ready? SCSI controller default
LXe Pro and LX Pro systems shipped between July
96 and November 96
Yes Ultra SCSI
LXe Pro and LX Pro systems shipped after
November 96 or with Navigator CD release ver.
G.00.00
Yes Fast-Wide SCSI
LH Plus, LH Pro Yes Fast-Wide SCSI
HP Storage System/6 No*
LC, LH, LS, E Series No
* The HP Storage System/6 does not support Ultra SCSI because of the cable length limitation of Ultra
SCSI. Customers must set the NetServers integrated SCSI controller channel to fast-and-wide
SCSI if they wish to connect the SCSI channel to the HP Storage System/6. When a SCSI channel set
to Ultra-SCSI mode is connected to the HP Storage System/6 with Ultra SCSI drives, the Ultra SCSI
channel and drives will automatically try to communicate in Ultra SCSI mode, but data integrity is not
guaranteed over the long cable between the server and the external storage unit.
HPs overall strategy is to ship NetServers with Fast-and-Wide SCSI as the default setting and
Ultra-SCSI as an easy-to-turn-on feature. The reason for keeping Fast-and-Wide SCSI as the
default setting is that we want to prevent problems that may occur if customers connect a SCSI
controller set to Ultra-SCSI mode to an external HP Storage System/6. THE HP STORAGE
SYSTEM/6 DOES NOT SUPPORT ULTRA SCSI BECAUSE OF CABLE LENGTH
LIMITATION OF ULTRA SCSI.
HP sells 3 Ultra SCSI capable disk drives:
- 2.1GB Hot Swap Ultra SCSI disk drive (D3582C), and
- 4.2GB Hot Swap Ultra SCSI disk drive (D3583C)
- 9.1GB Hot Swap Ultra SCSI disk drive (D4289A) [available November 1996].
These drives are supported in HP NetServer LH, LH+, LH Pro, LS, LXe, LX, and Storage
System/6. They are compatible with Fast SCSI for those systems that do not support Ultra SCSI.
They will provide Ultra SCSI functionality on LH+, LH Pro, LXe, and LX only.
