      Hi Aru,

      Changing the queuedepth in ESX 4 is quite similiar to changing the queue depth in ESX 3.5. For the example I used the popular qlogic qla2300_707 driver

      1. Open a connection to the service console.
      2. Issue the command: vicfg-module -s ql2xmaxqdepth=64 qla2300_707
      3. Reboot the system.

      With ql2xmaxqdepth=64 setting the queue depth to 64

      The vSphere SAN guide list also how to change the QD of an emulex , it’s listed on page 70/71. http://www.vmware.com/pdf/vsphere4/r40/vsp_40_san_cfg.pdf

      Good luck!
