Probably only me... but we have seen a higher latencies when using VMWare, also i think it depends on the H/W and VM configuration.... I have to figure out why (You might also try to mix the application's which runs on the hw).... i think there are people who run it on Amazons EC.

So, what I want to do is something like a private cloud storage solution.
I belive the http servers and application servers should be set up on virtual VMs, but what about the Cassandra and Hadloop servers, should their be set up on VMs or directly on physical machines? If they should be set up on VMs, the data of Cassandra and Hadloop should be stored in local storage or a Storage Repository?

Thanks,
Dennis
