5.1.2 Number of Tags Reserved for Each Host-LUN
Connection
Each nexus has 32 (the default setting) tags reserved. When the host
computer sends 8 I/O tags to the controller, and the controller is too
busy to process them all, the host might start to send less than 8 tags
during every certain period of time since then. This setting ensures
that the controller will accept at least 32 tags per nexus. The
controller will be able to accept more than that as long as the
controller internal resources allow - if the controller does not have
enough resources, at least 32 tags can be accepted per nexus.
