Queuing Registers - Allows Adaptec AHA-3960D Ultra160 PCI 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 number 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 Adaptec AHA-3960D Ultra160 PCI controller. The SCBs for disconnected transactions are only of use to the controller when the transfer is resumed. The solution to this problem is SCB Paging, a concept similar to memory paging.

When the host queues another transaction for the controller to execute, the controller firmware will use a free SCB if one is available. Otherwise, the state of the most recently disconnected and therefore most likely to stay disconnected SCB is saved, via dma, to host memory, and the local SCB reused to start the new transaction.
This allows the controller to queue up to transactions regardless of the amount of SCB space. Since the local SCB space serves as a cache Adaptec AHA-3960D Ultra160 PCI disconnected transactions, the more SCB space available, the less Adaptec AHA-3960D Ultra160 PCI bus traffic consumed saving and restoring SCB data.
Controllers with this problem have a 42 MHz clock crystal on them and run slightly above 10MHz.
