Most decent storage equipment meant for SANs has redundancy everywhere. Double powersupplies, double storage processors with mirrored memory/cache, and naturally the possibility to configure the disks in a fully redundant manner. It's easy to make the connection from the hosts to the storage redundant, too - just use two HBAs and two switches, and make sure both of the switches are connected to all the other end points (both SP's on the storage and both servers). In my opinion using a SAN is perfectly adequate for HA needs (it has not failed me, at least!), but it's your call of course. :-) Kind regards, -- Tore Anderson --- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
