'big data' is essentially an attempt to do real-time analytics on un-structured and semi-structured data. It is akin to the the ETL (extract, transform, load) Data Warehouse operations with queries that break the performance of row oriented schemas and many column oriented ones.
To do this, storage, network, and compute all need a generous boost in performance.
I don't consider 'Big Data' as hyper, it's already produced a lot of revenue generating applications.
But to be more than an arms supplier, which is failing to compete in this area, you really need the skills of a data scientist in statistics and similar skills to make sense of these new data streams; twitter, facebook, etc...
I wouldn't expect Cray to have anything of note to say unless it full filled the above needs.
oh and btw, a key tenant is big CHEAP in Big Data. I don't see Cray being that.
