the -really- hard part is maintaining write cache coherency across
redundant storage servers. thats what seperates the pros from the toys.
btw, the product that the OP was asking about, the Quantum StorNext, I

Quantum is selling it as a "Data Sharing and Archive" software, its not

Quantum acquired it when they picked up ADIC, who in turn had bought the
original company that had developed it.
