[Michael Williams] “every knowledgeable person has said they should scrap it and get something new.”
I’d question that opinion. You can easily upgrade your components to have a current system.
Full disclosure: It’s no secret that I’m a HUGE x-SAN fan. We’ve been using them for about five years now. While there are many other economical options out there, few of them can scale the way X-SAN can. If you anticipate much growth in the future, then many of the choices discussed above would seriously limit your ability to add clients. X-SAN’s expansion capability is so high that chances are you’ll run out of real estate before you run out of space on the SAN.
If you’ve already got X-SAN in place, I’d take a careful look at which of the components you have are still viable. You should not underestimate the benefits of a file based system as opposed to a volume based system. The larger your work group, the more important this distinction becomes. I could go on and on, but I’m curious, what’s driving the decision to toss what you’ve got?
By the way, that software version is WAAAAY old now. The current version is 2.2.
