Yes, you can.  You just install Virtual Center and add the ESX hosts
(provided you can enough licenses to add all your [physcial] hosts).
For 30 servers I'd *guess* that would be around three physical hosts.

True;  but at the last VMworld they did announce they are going to
refactor Virtual Center [which sucks, Windows or not, currently] to be
cross platform.

The toolset, documentation, and support/community are really important
to successful virtualization;  VMware easy trumps other solutions in all
those categories IMO.
