[Xen-users] Xen (SLES) vs VMWare Enterprise Plus and Essentials Plus

[James Pifer <jep@xxxxxxxxxxxxxxxx>]

Our company currently uses Xen on SLES11. Many people are pushing for 
VMWare. I've done some searching, including this matrix here:
http://www.virtualizationmatrix.com/matrix.php?category_search=all&free_based=1

This matrix doesn't specifically cover xen/sles11 but does have Redhat 
and XenServer, which are comparable. We also currently use a third party 
application for central management of all servers, which provides HA, as 
well as granular administrator assignments for support people, among 
other things.
If cost was not a factor, are there any technical real reasons to NOT go 
with VMWare vSphere? For example, using Enterprise Plus at the data 
center and Essentials Plus at remote facilities. As far as I know VMWare 
does not have a central management feature, where you can manage the 
whole environment from one point, but I've heard that's coming?
I was hoping to hear from the experts on this list that have experience 
with both. I honestly love my xen environment, at the same time, it does 
have shortcomings, that I'm guessing VMWare would cover a lot better, 
such as snapshots.
Anyway, if anyone is willing to comment I would appreciate it.

Thanks,
James
