Hi Friend,
1. Just go through these QUEUE terminologies given below and then read KB again :
- AQLEN
The storage adapter queue depth. This is the maximum number of ESX Server VMKernel active commands that the adapter driver is configured to support.
- LQLEN
The LUN queue depth. This is the maximum number of ESX Server VMKernel active commands that the LUN is allowed to have. (Note that, in this document, the terminologies of LUN and Storage device can be used interchangeably.)
- WQLEN
The World queue depth. This is the maximum number of ESX Server VMKernel active commands that the World is allowed to have. Note that this is a per LUN maximum for the World.
Not sure on remaining questions, let me dig out .
