[Beowulf] EMC PCIe flash storage

[Lockwood, Glenn]

This is the technology that TACC will be deploying this year and putting into production in January 2015:

We'll see how it stacks up for uses in HPC then.

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.
