When you say "local disk" and "backend storage," I assume you're talking about the local sas/sata disk, and the SAN storage, right? Both of these are a couple orders of magnitude slower than the physical ram, so, if your SAN is faster than your sas/sata disk, why not put your swap on the SAN? _______________________________________________ Tech mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
