    Title

    IBM SCSI-2 Fast/Wide Adapter/A, IBM SCSI-2 Differential Fast/Wide Adapter/A, IBM 2GB SCSI-2 Fast/Wide Disk Drive

    Abstract

    The IBM SCSI-2 Fast/Wide Adapter/A is a dual ported fast and wide (two bytes wide) SCSI-2 Micro Channel adapter that provides synchronous SCSI bus data rates of up to 20 megabytes per second for attachment of SCSI disks, CD-ROMs, tape devices, read/write optical devices and storage subsystems on many of the RISC System 6000/(TM) family of processors. The internal and external port are each capable of addressing up to seven single ended (SE) SCSI devices providing a maximum of 14 devices per adapter. The number of physical devices attached to each port is limited by SCSI bus cabling restrictions. (See the Limitations section of this Announcement for these restrictions.)

    The IBM SCSI-2 Differential Fast/Wide Adapter/A is a dual ported fast and wide (two bytes wide) SCSI Micro Channel adapter that provides synchronous SCSI bus data rates of up to 20 megabytes per second for attachment of Differential SCSI disks, disk subsystems, tape devices and read/write optical subsystems on many of the RISC System/6000(TM) family of processors. The internal single ended (SE) port is capable of addressing up to seven single ended (SE) SCSI devices and the differential external port is capable of addressing up to seven differential SCSI devices providing a maximum of 14 devices per adapter. The number of physical devices attached to each port is limited by SCSI bus cabling restrictions. The external differential port has the capability of supporting a total cable length of 25 meters (82 feet).

    Additional system, subsystem and high availability connections are also now available with the differential system-to-system and Y-cable features.

    The 2GB SCSI-2 Fast/Wide Disk Drive is a 2GB disk drive for attachment to the SCSI-2 Fast/Wide Adapter/A and cables which feature a 16-bit interface. (TM) Trademark of International Business Machines Corporation

    Description

    IBM SCSI-2 Fast/Wide Adapter/A

    IBM SCSI-2 Differential Fast/Wide Adapter/A

    GROWTH ENABLEMENT - Connectivity Improvement:

    IBM SCSI-2 Fast/Wide Adapter/A (FC#2415)

    The IBM SCSI-2 Fast/Wide Adapter/A is a dual ported fast (10 Mhz) and wide (2 bytes wide) SCSI-2 Micro Channel Adapter that can provide synchronous SCSI bus data rates of up to 20 megabytes per second. It provides high performance attachment to single ended (SE) SCSI disks, CD-ROMs, tape devices, read/write (R/W) optical devices and storage subsystems. The maximum data rate is dependent on the maximum data rate of the devices.

    The IBM SCSI-2 Fast/Wide Adapter/A has one usable internal SE port and one external SE port. Each SE port is capable of addressing up to seven SE SCSI devices. The number of physical devices attached to each port is limited by SCSI bus cabling restrictions. (See the Limitations section of this Announcement for these restrictions.) The internal port of this adapter supports either 8-bit or 16-bit devices via a 8-bit or 16-bit connector. Only one of these two connectors may be used at one time. (Devices of different bus attachment widths cannot be connected/used at the same time.) External cabling may be up to 6 meters (19.6 feet) when attached to the IBM 9334-010 or 9334-500, 3 meters when attached to anything else and is supplied by the attaching device.

    Characteristics:

    IBM SCSI-2 Differential Fast/Wide Adapter/A (FC#2416)

    The IBM SCSI-2 Differential Fast/Wide Adapter/A is a dual ported fast (10 Mhz) and wide (2 bytes wide) SCSI-2 Micro Channel Adapter that can provide synchronous SCSI bus data rates of up to 20 megabytes per second. The SCSI-2 Differential Fast/Wide Adapter/A provides high performance attachment to Differential SCSI disks, disk subsytems, tape devices and read/write optical subsystems. The maximum data rate is dependent on the maximum data rate of the device. The IBM SCSI-2 Differential Fast/Wide Adapter/A has one usable internal single ended port and one external Differential port. The internal port is capable of addressing up to seven single ended devices, the external port is capable of addressing up to seven differential devices. The number of physical devices attached to each port is limited by SCSI bus cabling restrictions. (See the Limitations section of this Announcement for these restrictions.) The internal port of this adapter supports either 8-bit or 16-bit devices via a 8-bit or 16-bit connector. Only one of these two connectors may be used at one time. (Devices of different bus attachment widths cannot be connected/used at the same time.) The external Differential SCSI bus is capable of supporting cable lengths of 25 meters (82 feet).

    Additional system, subsystem and high availability connections are also now available with the differential system-to-system and Y-cable features.

    Product Positioning

    These SCSI-2 Fast/Wide Adapters are IBM's high performance SCSI connections to the wide range of RISC System/6000 storage devices and subsystems, and conform to the latest SCSI standard used in the open systems marketplace. By contrast with the previous SCSI-1 and SCSI-2 Controllers and Adapters for the RISC System/6000, they offer:
    - Double the maximum synchronous data transfer rate, from 10 MBps to 20 MBps
    - Greater flexibility in physical planning due to the increased SCSI cable lengths possible with the Differential adapter
    - Double the number of devices, from 7 to 14. These new adapters also offer upward compatibility with existing IBM devices. As before, however, note that single-ended SCSI devices and controllers cannot be mixed with differential SCSI devices and controllers on the same SCSI bus. Since these adapters provide this new capability at the same price as the predecessor SCSI-2 and SCSI-1 adapters, new and current RISC System/6000 customers should choose the new SCSI-2 Fast/Wide Adapters rather than the older products when selecting a new SCSI controller. There may be some isolated exceptions, noted in the Limitations section.

    Cable length restrictions

    The maximum length guideline for SCSI fast operation is typically three meters unless specialized cableing and termination are utilized as in the case for the IBM SCSI-2 Controller implementations. These tuned configurations extend operation of IBM-supported devices up to six meters, provided that IBM-supported cables and terminators are used.

    Additional information about cable length restrictions can be found in the document ANSI Doc X3T9.2/86 rev 10h.

    Programming Requirements

    The IBM SCSI-2 Fast/Wide Adapter/A and IBM SCSI-2 Differential Fast/Wide Adapter/A require updates from the initial release of AIX 3.2.5. Customers ordering systems with AIX 3.2.5 will receive these updates on the system or media. Customers ordering hardware separately must ensure access to the latest update of AIX 3.2.5. See Programming Announcement ZP940264 (RFA 22727) dated May 24, 1994 for more information.
