Interestign article.
Nothing specific that hasn't been seen before - but putting this together
at rack scale is very impressive.
A petabyte of data available with extremely low latency.

I have to say though - the fibrechannel is looking like an increasingly
limited technology.

The point could be made that fibrechannel has the ability to cope with
failure, and multipathing should a controller or HB fai - I wonder how
riobust PCIe is to failures.
But darn it to heck - we are in high performance computing. My take is that
you will tolerate some fragility to get that sort of performance.
