Abstract : An improved SCSI controller provides a logical connection between a plurality of host processors using a single SCSI initiator. The controller contains removable host adapters for connection to any type of host processor interface. When a host processor requests status information of a target device, that status information is passed to the requesting processor and subsequently stored in the controller and made available to all other host processors. The advantage to such a controller is the expanded number of host processor connections to a single SCSI initiator whereby each host processor can independently and logically connect through the controller and SCSI initiator to a target without clearing target status information for other host processors. The invention is particularly advantageous when adapted to function in a local area network (LAN) arrangement where a significant number of host processors are requesting data from one mass storage device.
