8.1.2 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.
