Abstract
A Fibre Channel (FC) controller shareable by a plurality of operating system domains (OSDs) within a load-store architecture is disclosed. The controller has a FC port that obtains a plurality of FC port identifiers for association with respective ones of the OSDs. A load-store bus interface is the target of a load-store transaction on a load-store bus from each OSD. The load-store transaction includes a command to perform an I/O operation with a remote FC device. Association logic populates an S_ID field of a FC frame with the FC port identifier associated with the respective OSD that initiated the command. The FC port transmits the FC frame on the FC port to the remote FC device. In one embodiment, the controller interfaces to an Advanced Switching fabric to receive packets encapsulating load-store transactions from the OSDs. Each packet includes an identifier identifying the OSD initiating the transaction.
