At least on S10u8 its not that bad. Last time I patched and rebooted a X4500 with ~350 ZFS it took about 10min to come up, a X4600 with a 3510 and ~2350 ZFS took about 20min (almost all are shared via NFS). Shutting down/unshare them takes roughly the same time ... On the X4600 creating|destroying a single ZFS (no matter on which pool or how many ZFS belong to the same pool!) takes about 20 sec, renaming about 40 sec ... - that's really a pain ...
