Just wanted to add something to this thread, which has not been mentioned yet. Sure, most (if not all) SANs are supported vie generic linux kernel drivers for HBAs, something like a QLogic card, or an exported iSCSI LUN. The issue is that you spent tons of money on the SAN and a truck load of money on hardware and software to hook up to that SAN. So you want to have a vender supported OS to go along with these items. If you have performance issues or stability issues, the first things a vender will ask is, what OS are you running, so they can direct you to the correct support group. The support group will want to debug the issue, so you have to generally run something like RHEL or Windows to get support. This might only be a mega corp issue though, since most startups don't have Oracle/Sybase, fiber channel SANs, etc. To sum this up, in the mega corp world, if you are not running a vender supported OS, you likely cannot get support for your device.
