Adaptec - AHAUW-OF
Queuing Registers - Allows queuing of new transactions without pausing the sequencer. The SCB contains all of the information required by the controller to process a transaction.
The chip feature table lists the Adaptec AHA-3940UW PCI SCSI of SCBs that can be stored in on-chip memory. Using the SCBs in a straight forward manner would only allow the driver to handle as many concurrent transactions as there are physical SCBs. To fully use the SCSI bus and the devices on it, requires much more concurrency.
The solution to this problem is SCB Paging, a concept similar to memory paging. SCB paging takes advantage of the fact that devices usually disconnect from the SCSI bus for long periods of time without talking to the controller.
The SCBs for disconnected transactions are only of use to the controller when the transfer is resumed. When the host queues another transaction for the controller to execute, the controller firmware will use a free SCB if one is available.
