Deep inside tape storage
With the capacity of completing in excess of a quadrillion calculations per second on a sustained basis -- and ten times that at peak performance -- Blue Waters was meant to be ideal for providing the scientific community with the processing speed, data storage, memory, and communication necessary to take on many of the most complex computing tasks.
The supercomputer comprises 22,640 Cray XE6 nodes and 3,072 Cray XK7 nodes with NVIDIA graphics processor acceleration. The XE6 nodes have 64 GB of memory per node, while the XK7s each have 32 GB of memory. Blue Waters also boasts a quick online storage capacity of 26 petabytes, and 380 petabytes of longer term tape data storage.
This is a look inside one of the Spectra T-Finity cabinets that make up the 380 petabytes of long term storage.
