VMware has just released ESX Update 4. You can find the release notes here. I’ve picked a couple of bullets which I think are important, please read the release notes for the other improvements and known issues!

vSphere 4.0 Quick Start Guide
Hi Duncan, I’m curious about the LUN Queue depth throttling. Tell if i’m wrong : ESX received from the storage array a BUSY or QUEUE FULL status so the VMkernel throttles the LUN queue depth. What’s the benefice effect of this algorithm ?
Thanks.
Applying the U4 update will knock the newly HCL-certified Intel Gigabit ET Dual Port Server Adapter (E1G42ET) off-line. I’ve already burned several hours on this and am currently waiting on VMware support.
If you have any of the new Intel third-gen NICs like the E1G42ET, I recommend you tread carefully so as not to waste time like me!
FYI: The ESX 3.5 U4 update problem is fixed. If the E1G42ET driver is installed prior to U4, U4 will overwrite it with the older v1.0.0-82663 version, a version that does not support the E1G42ET. Furthermore, attempting to reapply the E1G42ET patch with “esxupdate update” or even “esxupdate –force update” does not work.
Here’s what we did to fix it:
1. rpm -qa|grep “igb”
Output: VMware-esx-drivers-net-igb.350.1.0.0-82663
[This is the old driver that U4 installed]
2. rpm -e VMware-esx-drivers-net-igb.350.1.0.0-82663
[Uninstall the old driver]
3. mount the E1G42ET Driver CD: ‘ESX 3.5 Driver CD for driver “igb” version 1.3.8.6.3′: umount /dev/cdrom /mnt/cdrom
4. rpm -ivh /mnt/cdrom/VMupdate/RPMS/VMware-esx-drivers-net-ibg-350.1.3.8.6.3-i386.rpm
[Install the new driver]
5. reboot
Back on-line!
Andre at VMware Support said that he’ll write up a KB on this. Cheers,
