"....Suspicion has fallen on this chip...."
So, if this is a problem where one chip on one flash card can take down the whole array, regardless of the number of flash cards in use, that implies there is a single point of failure in any FAS6000s using the flash cache cards. Major whoops! If it restarts, do you lose write data in the cache? It would be interesting to know if the chance of the problem increases linearly with the more cards you have, which would seem reasonable if it's a random number of dodgy chips, or whether the problem is software/firmware related and the chances of it happening are much greater the more flash cards you have in operation at once.
What are the legal implications if you have a FAS on support but don't agree to the confidentiality clause, can NetApp really refuse to supply a fix? I know Sun tried this with us in the past and we told them to take a hike, any brave NetApp users out there not toeing the line?
