Target mode refers to the ability of some SCSI host adapters to respond on the SCSI bus as if they were a SCSI target (device) instead of an initiator (host) which is the usual behavior. Using target mode two hosts can communicate with each other over the SCSI bus at high speeds. Although most SCSI chips can be used in target mode, not all host adapters support it. Here are some that do: Adaptec 2940UW (http://www.adaptec.com/) The documents that describe how target mode works for the 2940/2944 are called: Designer Book AIC-7880 SCSI Chip Specification Adaptec TARGET mode firmware programming guide (I don’t think any of these is available anymore) NexiTech provides target mode software for the 2940 adapter. (http://www.nexitech.com/) Virtual SCSI has software that works with their own cards. (http://www.virtualscsi.com/) Qlogic QLA-1040 (http://www.qlc.com/) cards support target mode also.
