Well, yes, ... that's sort of why I'm asking the question :-)

The question implies that I don't see a possibility for this.

Personally, I would create a storage cluster and a VM cluster,
allowing for epxansion of the virtual nodes later if time/budget

That's what I've done. Overall throughput is quite good, but seems to
suffer a bit on small writes.

Which leads to two follow-up questions:

1. Can I assume that you're both suggesting a 4-node storage cluster,
and a 4-node VM cluster - running on the same 4 computers? If so, that's
sort of what I'm aiming for.

No, we're suggesting two 2-node clusters, one for storage, one for virtualization.

2. What software are you running for your storage cluster?

I'm running IET. Next project I would try AoE though.
