Abstract
Abstract A Fibre Channel to SCSI Addressing method and system is provided. The system associates with a Fibre Channel and a SCSI bus. The system further maintains a Fibre Channel to SCSI routing table (90) and a SCSI to Fibre Channel routing table (92). The system receives a cross bus transfer of data that originates on either the Fibre Channel or the SCSI bus, respectively, and wherein the cross bus transfer is intended for a target on the SCSI bus or Fibre Channel, respectively. The apparatus translates addressing information contained in the cross bus transfer by referencing either the Fibre Channel to SCSI routing table 90 or the SCSI to Fibre Channel routing table 92.

Claim 1
Independent Claim
133 words
A computer implemented Fibre Channel to SCSI addressing method, comprising: maintaining a first table of Fibre Channel to SCSI bus routing information; maintaining a second table of SCSI bus to Fibre Channel routing information; receiving a cross bus transfer, wherein the cross-bus transfer is initiated by a device on a Fibre Channel or a SCSI bus, respectively, and further wherein the cross bus transfer is intended to be delivered to a target device associated with the SCSI bus or the Fibre Channel, respectively, and further wherein the cross bus transfer contains addressing information that specifies a target for the cross bus transfer; and translating the addressing information by comparing the addressing information to either the first table or second table, respectively, such that the cross bus transfer can be delivered to the target.
Claim 2
Dependent Claim
