GROWTH ENABLEMENT - Connectivity Improvement:
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.

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.
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.
