Adapter for interfacing a SCSI bus with an IBM system/360/370 I/O interface channel and information system including same
First Claim
1. A data processing system including a plurality of computer systems, the data processing system comprising:
- a first computer system having an IBM System/360/370 I/O interface channel, the first computer system operable to communicate SNA and non-SNA protocol information via the IBM System/360/370 I/O interface channel;
a second computer system having a SCSI bus, the second computer system operable to communicate SCSI protocol information via the SCSI bus; and
an adapter coupled to the IBM System/360/370 I/O interface channel of the first computer system and the SCSI bus of the second computer system, the adapter operable to interface the SCSI bus with the IBM System/360/370 I/O interface channel to allow bidirectional communication between the IBM System/360/370 I/O interface channel of the first computer system and the SCSI bus of the second computer system.

Abstract
An information system (10) including a plurality of computer systems is provided. The information system (10) includes a first computer system (16) having an IBM System/360/370 I/O interface channel (18). The first computer system (16) is operable to communicate SNA and non-SNA protocol information via the IBM System/360/370 I/O interface channel (18). The information system (10) includes a second computer system (40) having a SCSI bus (38). The second computer system (40) is operable to communicate SCSI protocol information via the SCSI bus (38). An adapter (36) is coupled to the IBM System/360/370 I/O interface channel (18) of the first computer system (16) and the SCSI bus (38) of the second computer system (40). The adapter (36) is operable to interface the SCSI bus (38) with the IBM System/360/370 I/O interface channel (18) to allow bi-directional communication between the first computer system (16) and the second computer system (40).
