I seem to recall...
I seem to recall that EMC undertook that if they ever dropped Centera that its code base would become open sorced. I hope this is still the case.
Also, 1.5PB seems rather a low number for the total data stored in centera, especially considering that its generally used for image stores, telephone voice recording or the like.
Finally, the company I work for has _a_ _lot_ of centera and EMC hardware in general, I hope for our account manager's sake that they aren't stopping the centera line because he'll be on the end of a savage beating with a big stick labelled IBM.
