Nope, that's not what this product is at all. It's GPFS. You could bang all three of those together fifty ways and not reinvent a distributed filesystem, so I have no idea what you're talking about. (Seriously? Lucene?)
Speaking as (I'm sure) one of the few people in this thread who will have used GPFS: GPFS is actually quite good. You'd be surprised how good it is. It has its downfalls, but it is extraordinarily useful, performs well, and just about hits the holy grail of distributed POSIX. It's also absurdly expensive, but: IBM.
