They're actually buying constant-sized chunks of virtual storage, which
is provided through a pool of SAN-based disk space. This means that
we're always going to have a certain number of logical pools of storage
space to manage that are expanded in fixed-size chunks; the question is
whether to manage them as separate ZFS pools or to aggregate them into
fewer ZFS pools and then use quotas on sub-hierarchies.
(With local storage you wouldn't have much choice; the physical disk
size is not likely to map nicely into the constant-sized chunks you sell
to people. With SAN storage you can pretty much make the 'disks' that
Solaris sees map straight to the chunk size.)
