I would ask DDN this, but my guess is that even if the drives work, you
would run into support headaches proving that whatever problem you're
running into isn't the result of 3rd-party drives. Even with supported
drives, we've run into drive firmware issues with almost all of our storage
systems (not just DDN, but Isilon, Hitachi, EMC, etc.); for supported
drives, it's a hassle to prove and then get updated, but it would be even
worse without support on your side.
