After you understand certain criteria for nonhomogeneous queues, you
can calculate their queue depth in Fibre Channel hosts.
Nonhomogeneous queues must meet one of the following
criteria:
- One or more servers must be allocated more resources so that they can queue more commands.
- Volumes must not be distributed evenly among the I/O groups in the clustered system.
Set the queue depth for each volume on the servers by using the following parameters:
- For each volume, consider each server to which that volume has a mapping. This consideration
results in a set of server/volume pairs.
- If the sum of the server and volume queue depth for all of the pairs is less than 7000, the
server does not experience problems due to a full queue.
