Re: [Linux-cluster] VMware over GFS?

I've not used ESX yet, my servers are VMware Server 2.0 so far. I'm wondering if I should be looking at Xen for example rather than trying out ESX. I have a handful of win machines and the rest will always be linux. The VM server itself will also always be linux.

Maybe I missed it in your message but did you mention which versions of windows this runs on? Does the VM environment work well under win? I'm so used to win being bloated, slow, sluggish, it takes huge amounts of hardware resources to counter that usually.

I do have centralized storage of various protocols so would be ok there.

The organization I'm helping doesn't have the budget which is why I've been using open source, free tools as much as possible. They wasted so much money on useless things in the past, I'm trying to help them save money and get back on track.

Cost is always an issue, not for everything but sometimes, for the things we do need.
