Solution

Summaries and Symptoms

VMware ESX 3.5 update 4 introduces an adaptive queue depth algorithm that adjusts the LUN queue depth in the VMkernel I/O stack. When congestion is detected, VMkernel throttles the LUN queue depth. VMkernel will attempt to gradually restore the queue depth when congestion conditions subside. By default, this algorithm is disabled. You can enable it by following the instructions in KB article 1008113 at http://kb.vmware.com/kb/1008113.

Patch ESX350-200903201-UG is also required to complete this fix.

Deployment Considerations

None beyond the required patch bundles and reboot information listed in the table, above.

Patch Download and Installation

See the VMware Update Manager Administration Guide for instructions on using Update Manager to download and install patches to automatically update ESX Server 3.5 hosts.

To update ESX Server 3.5 hosts when not using Update Manager, download the most recent patch bundle from http://www.vmware.com/download/vi/vi3_patches_35.html and install the bundle using esxupdate from the command line of the host.
