If I need disk space, I would attach a persistent volume... in my use cases the SAN storage has already 12 SAS 15k disks and the additional enclosure as well as the disks are expensive well, i have rotating backups of the whole setups too and so at least i have to multiply the storage by 3 or 4 > I'd care much more about memory usage, boot time (you want to spin > things up fast), and cpu usage (cpus are likely the most scarce > resource for me at least) 30 Fedora VM's on a single HP DL 380 average 5% CPU usage that different the usecases are
