Curious on which one I should install. This is going to be installed on an HP ProLiant DL380 G7, which did come with the HP Insight Ctl Mdl/DL Bdl. With this being the case should I install the HP customized offering? Not certain what the U1 means...or should I just go with the base ESXi 4.1 Installable.

Go with the 4.1 installable - there's plenty enough HP-specific stuff already in the generic version already, sure you miss out on knowing a few temperatures sensor readings but 4.1 is really worth the effort, loads of cool new stuff in there - we've moved all of our ~8,000 hosts over already.

Sounds good...what does that U1 represent anyways...? Hopefully not a reversal of the rack sizing 1U, 2U...:) – Aaron McIver Dec 2 '10 at 15:50
@Aaron U1 is Update 1, VMware label the major sub version releases as Update X, e.g. ESX 3.5 Update 4 etc. I'd also vote for the VMware sourced package - updates on the vendor specific variants have been very slow and the benefits are limited. – Helvick Dec 2 '10 at 16:24
@Helvick, makes sense...thanks... – Aaron McIver Dec 2 '10 at 16:25

ESXi 4.1 is the latest offering on VMware for Enterprise Virtualization. ESXi 4.0 U1 (Update 1) is the older version of ESXi. Update 1 is like SP1 for ESXi 4. One of the main improvements in ESXi 4.1 is pass through USB support.

You will get the HP customized version of ESXi 4.1 here. Click on Receive for Free >>.

You will need a HP account(free to create) to download. The page is for VMware ESXi 4 and higer. So select ESXi 4.1 for the list of items.
