yes - you are correct. I was confused, most likely due to low caffiene levels.<br>We've piloted both Centos and the free Vmware Server package along side of the paid "ESX" for that particular customer, on the production hardware (white boxes with supermicro main-boards). <br>
Still - we're awaiting the customers decision and have strongly urged him to consider purchasing ESX for production servers mainly for the support. As far as our pilot is concerned, the performance for both configurations (CentOS/Vmware server free vs. ESX) was satisfactory.<br>
<br>I think our biggest mistake from this case study was the whitebox hardware...it was cheap and the customer wanted 2 servers per location with one acting as a hot spare. This actually worked quite well with custom scripting to snapshot the vm's and rysnc them across both physical machines....so that's something to keep in mind.<br>
<br>One last thought about the latest versions of Vmware server, they changed the GTK based GUI mangement application to a web-based application and removed an number of the command-line tools, which I found disappointing. The web based GUI management application is slick and has new features (esp regarding snapshots), but it's slow and cumbersome over WAN lines that aren't up to par.<br>

Hi all,<br>
<br>
Hey John, what do you mean moving to CentOS and ESX? If you're running<br>
ESX, there is no host OS -- ESX *is* the base OS. The only OSes you<br>
install are in the VMs themselves.<br>
<br>
As for Ubuntu, it's listed in the VMWare Server Admin Guide as being a<br>
supported host OS. In addition, you can actually install vmware server<br>
on ubuntu straight from the Canonical commercial software repository.<br>
When it comes to VMWare, I really do advocate looking at all of the<br>
documentation even before you purchase the product, because there's a<br>
lot of information to digest, and if you don't read it, especially for<br>
hardware and host OS compatibility, you're likely to make an error in<br>
your deployment plan that'll cost you a lot of time (at least).<br>
<br>
If you have some budget for this project, I would *strongly* recommend<br>
going with ESX for production boxes, perhaps using the free server for<br>
prototyping and testing new VM builds that can then be migrated to an<br>
ESX server and launched into production. I'll leave out the VMotion<br>
details, since that requires an enormous budget and probably hardware<br>
purchases on top of that :)<br>
<br>
My experience with ESX has been unbelievably good, and all of you who<br>
know me know I don't say that much. ;-P They release updates in a<br>
timely manner and performing updates in my experience has been dead<br>
easy, and flawless, and has never affected the stability of anything<br>
running on it. I've run both Windows and Linux on ESX (on the same<br>
hardware, in fact). It "just works".<br>
<br>
Good luck!<br>
<br>
<br>
