We are in the process of designing an entry level ESXi platform and need assistance with licensing costs.
From my initial understanding ESXi was free, however that was a little naive on my behalf, not realising that was only for a single host, not clustered. And after spending some time trying to get a handle on what I would need to spend (minimum) I found a number of alternatives, none really clear to me.
What we are aiming for is a 5 server ESXi cluster, with redundancy, all storage on a iSCSI SAN. I'm not sure whether HA is the same as redundancy and/or whether v-motion takes part as well (or is outside of scope).
So, do we need virtual center for the above? Will foundation (http://www.vmware.com/products/esxi/buy.html
) cover the above core requirements? Is there another approach (e.g. using MS clustering)?
Apologies for such a rambling question.
