I have recently installed ESXi4 on a new HP DL380 G6 with 12GB of memory. I am running CentOS 5.4 and CentOS 4.8. A few things I have learned.

First, for best I/O performance you should use the Vmware Paravirtualized storage controller driver. It's a little bit of a hassle setting it up. You just have to remake the initrd file. This will give about 10% better disk I/O than using the other emulated controllers.

Does this happen by itself if you've installed vmware tools in the guest and then get a kernel update that triggers an initrd rebuild or do you have to do something to specify the right module to include?
