Definitely. In fact one of our volume groups has 55 LV's:
# vgs
VG #PV #LV #SN Attr VSize VFree
t0core 1 55 0 wz--nc 4.08T 3.63T
This is a clustered LVM too, shared among 4 dom0 hosts.
You could accomplish the same creating as many LUNs on your SAN, but it
tends to be more work and the volume labels are not as clear. The only
advantage I see is that you won't have to work around the limitations of
a CLVM (e.g. single-host snapshots).
(It'd be nice too if the Xen tools handled automatic LV
activation/deactivation when bringing up a domU or migrating.)
