I have two installations on ESX 3.5 Update 2 currently in testing, one running on Solaris and the other on Ubuntu, both the 3.0 branch. They are running with no disk cache however, and pointing at parent proxies. I was concerned about how our iSCSI SAN would handle the cache as it is recommended not to run on raid. Though I am planning to test that as well, I just have to get a few other projects finished first. I have ran into no problems with either installation so far. They seem to handle the live migration moves between servers with only a slight slow down in operation during the move. The load when I go into production will be around 500 users as well, though I have only had about 25 users pointed at the test installations. I have considered doing a FreeBSD install as that's what I have been using for a long time on physical hardware, but being that it is not officially supported by VMWare, I have been hesitant to try it for fear that it might hurt the ESX servers performance. I hope this helps you some, I still have a decent amount of testing to do before I would be willing to say it works and performs great, but so far it's been good.

We got about 500 Users, so there shouldn't be that much load on that machine. Maybe someone tested that and could just report how it works. Regards Jens
