Why in god's name would your DB server be on the same subnet as your wireless network? Never mind having some sort of arp-protection in place (ie if the local DHCP server didn't assign it's IP don't listen to it).

Let's be honest here, nobody in America ever cares about facts.

There's not a vCPU limit in HA as of at least ESXi 4.1 (or if there is it's really high). Maybe your're thinking of FT? That has some strange limitations.

Couple of corrections. HA (high availability) works without vCenter, if a host running vCenter dies HA will restart it on another host like any other VM. A vDS will continue to function you just can't connect VMs to the distributed switch. Lastly vCenter Heartbeat has been around for at least a year and can run in a few configurations. You can run it with two VMs (active/passive), maybe on different hosts/data stores or even buildings. You can also run it with the active vCenter on a physical machine that'll failover to a VM if need be.

Wait.. BSD isn't dead?

Or the main difference in that you manually have to make a choice and switch to opendns?
