Hello Shanker, Thanks for the response!
Seems like the biggest concern is storage, and rightly so. I'll actually be using ceph for storage across all of the nodes with a few replica's dropped in for good measure. Since the storage is local to the nodes, if more than a few nodes go out at the same time there is likely some other, larger failure event going on (loss of power or something). The chassis is essentially a blade chassis. IPMI is going to sit on it's own dedicated network, so I'll still have an OOB way to get in, but that costs me money and I'm cheap :) How would I go about piping the management traffic into a VM? Would this have to be done manually? I didn't see the option to attach the management network to an instance.
