SCSI Peripheral Host Adapter, Technical Data
For HP 9000 Series 300 DIO-I Computers Product Number 98658A
The Small Computer System Interface (SCSI) is a widely accepted ANSI
standard for connecting host computers to peripherals. SCSI peripherals
available in the market today include floppy and Winchester disks,
cartridge and reel-to-reel tape drives, CD-ROM, WORM drives, helical
scanners, and a wide range of other peripherals. The HP 98658A can
support 7 devices on one interface although performance and cable
restrictions will apply.
The HP 98658A host adapter provides a standard 8-bit SCSI bus for
HP 9000 Series 300 DIO-I* systems and is capable of performing 16-bit
DMA transfers. When connected with the 7957S, 7958S or 7959S SCSI 5.25"
disks from Disc Memory Division, it provides a high performance
solution for direct access storage. By itself, the 98658A provides the
flexibility of an industry standard and allows connection to compatible
peripherals.
Note: HP 9000 Models 310 and 320 are not supported.
Features
o Industry-standard interface
o Fully ANSI X3T9.131-1986 compliant
- Support of bus arbitration
- Full parity across the interface
- Single-ended transceivers
- Disconnect/reconnect
o High-speed throughput:
- asynchronous or synchronous mode
- 16-bit DMA transfers
Note: System level performance is application dependent and may not
reflect the higher I/O rate achievable with SCSI.
o Connects up to 7 devices per adapter
- 1-meter cable ships with the adapter card
- cable uses Alt 2 male connectors on each end
o Up to 6 meters connectivity distance
o Compatible with HP's 7957S, 7958S, and 7959S disks
o Support on HP-UX only, refer to HP 9000 Series 300 Configuration
Guide, P/N 5951-6796, for supported configurations.
o Customer installable

Warranties and Disclaimers
Standard HP 90-day warranty with purchase of the product.
HP fully supports SCSI for use with HP peripherals. Use of the SCSI
adapter with non-HP peripherals is at the users own risk and is not
HP supportable. Hardware and/or software may require modification for
system/peripheral compatibility. Upon modification of the software,
HP waives all responsibility for proper operation including transaction
accuracy and data integrity. Modification of software should only be
taken on by users experienced with HP-UX drivers and SCSI
implementations.
HP specifically disclaims the implied warranties of merchantability
and fitness for a particular purpose. In addition, HP specifically
disclaims all responsibility for the operation of the SCSI interface
software with non-HP products, and for results or data loss in
connection with use of the software.
