I would use some sort of SAN (fibre, iscsi, AoE, whatever) RAID so the disk is not physically tied to the blade. And perhaps use Xen for migration so the OS isntance is not physically tied to the blade either. Now you can replace disks AND blades without ever having downtime. -- Tracy R Reed http://copilotconsulting.com -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
