- 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

- 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.
