That's true about SANs in general. You don't buy a SAN because it'll
cost less than just buying the disks and a controller. You buy a SAN
because it'll let you make managing it easier. The break-even point has
more to do with how many servers you're able to put on the SAN and how
often you need to do tricky backup and upgrade procedures than it
doeswith the hardware.
