room to store the following number of CCBs internally; that is, they can

internally queue and manage this many active commands on the SCSI bus

Depth should be set to the Mailbox Count, rather than the Host Adapter

Queue Depth (internal CCB capacity), as it is more efficient to have the

queued commands waiting in Outgoing Mailboxes if necessary than to block
