I have a number of ESX servers hosting VM's, all but one of these works ok, however one server has a problem where any guests on not contactable over the network.

The ESX hosts is contactable, is integrated int VCenter, and you can even live migrate VM's to and from this server, but any VM's on that server are unable to talk to the rest of the network.

The VM's NIC is shown as Up and has the right IP configuration, and as soon as you move it back to another host it works fine.

What kind of storage do people actually use for VMware ESX servers?

as seen on Server Fault - Search for 'Server Fault'
VMware and many network evangelists try to tell you that sophisticated (=expensive) fiber SANs are the "only" storage option for VMware ESX and ESXi servers. Well, yes, of course. Using a SAN is fast, reliable and makes vMotion possible. Great. But: Can all ESX/ESXi users really afford SANs? My theory… >>> More
