The Cray brochure for this system has more information, including detailed specs: http://www.cray.com/Assets/PDF/products/cs/CrayCS-Storm.pdf http://www.cray.com/Assets/PDF/products/cs/CrayCS-Storm.pdf A few fun points from the brochure: - The internal network ("interconnect") is Infiniband in either a torus or fat tree topology - Up to 512 GB RAM per node - Power usage is up to 63 kW per rack - You have the option of including liquid-cooled rear door heat exchangers, if your datacenter air cooling isn't up to the task ;-) - Compute nodes can have disks installed, but the system supports diskless booting - Each compute node weighs 88 lbs One thing to remember about these machines is that the internal high-bandwidth, low-latency network is a big part of why they get such good performance. Most applications that run on these machines are long-running computations consisting of many processes spread across the entire machine, with lots of inter-process communication throughout the lifetime of the job. Think weather prediction, simulations of fluid dynamics, or complex mechanical systems. (I work on similar systems to these every day. Huge amounts of fun, but quite different needs than your typical web service, or even most Hadoop-ish data analysis problems.)
