ESX 3.5 patch 10 – what’s that?

According to the vSphere 4.0 release notes (http://www.vmware.com/support/vsphere4/doc/vsp_esx40_vc40_rel_notes.html)

vCenter Server 4.0 becomes unresponsive in large environments if managing ESX Server 3.5 hosts prior to ESX 3.5 patch 10
vCenter Server 4.0 can become unresponsive in large environments after 30 days if it manages any ESX Server 3.5 hosts prior to ESX Server 3.5 patch 10.
Workaround: Upgrade to ESX Server 3.5 Update 4 if you are running ESX Server 3.5 with vCenter Server 4.0.

What exactly is “patch 10”?   How do you know what build level qualifies?  Is there a single patch that can be applied?

If you upgrade to vCenter 4 and things become unresponsive after 30 days, patching all your disparate ESX servers isn’t going to be something that most large organizations can do quickly.  I’d say this is an important one.

I posed the question to my local SE, and several VMware contacts I have, but know one seems to know.  Can anyone out there on the tubes clarify this one?

Welcome to vReference

I’ve moved. vmreference.com is so old school.  I’ve decided to “keep up with the Joneses”, and become hip with the new vReference moniker.  After VMware decided to rename everything (again), I thought it might be a good idea to go with the flow.
It was also a good chance to update my website.  Hopefully I haven’t single handeldly broken those interwebz tubes, but let me know if any of the links haven’t come across properly.  I’ll keep the old URL, and permanently forward the DNS entry in the next couple of days, but please update your blogrolls and any links to my site or the ESX3 reference card.  The new RSS feed is simply:

http://www.vReference.com/feed

I’m currently working my way through all the vSphere4 documentation, and hope to have the vReference reference card for version 4 ready in the coming weeks.  I plan to create a brand new one, and maintain them both separately.  In the meantime, you might want to check out my growing vSphere4 notes .

I’m always looking for feedback, so if you have any, pop over here and let me know.

I for one welcome our new vReference overlords!
