If you are not satisfied with the performance of your Emulex adapter, you can change its maximum queue depth.

You can adjust the maximum queue depth for an Emulex HBA using vSphere CLI.

1

Verify which Emulex HBA module is currently loaded by entering the vicfg-module --server server -l | grep lpfc command.

2

Run the following command.

The example shows the lpfc820 module. Use the appropriate module based on the outcome of Step 1.

vicfg-module --server server -s lpfc0_lun_queue_depth=16 lpfc820

In this example, the HBA will have its LUN queue depth set to 16.

3

Reboot your host.
