Homogeneous queue depth calculation in Fibre Channel hosts

You must set the homogeneous queue depth to a calculated value in Fibre Channel hosts.

Set the queue depth for each volume on the servers by using the following calculation:

• q = ((n * 7000) / (v * p * c))

Where

• q = the queue depth per device path
• n = the number of nodes in the system
• v = the number of volumes that are configured in the system.
• c = the number of hosts that can concurrently access each volume. Few applications support concurrent access from multiple hosts to a single volume. This number typically is 1.
