Remember the Cray XK6 at the University of Illinois that drives the National Science Foundation's Blue Waters project? Well, it looks like it's getting a little memory upgrade, sorta. We're not talking a slick new SSD here, or even a sweet NAS, all that computational power requires nothing less than... tape. Okay, so it's actually a full storage infrastructure, and some of it -- 25 petabytes no less -- will be disk-based. The rest -- a not insignificant 380 petabytes -- will be the good old magnetic stuff. The idea is that the disk part will be used for instant access, with the tape section serving as "nearline" storage -- something between an archive and online solution. Spectra Logic is providing the tape, and says it'll take a couple of years to implement the whole lot. Once complete, the system will support the supercomputer's lofty tasks, such as understanding how the cosmos evolved after the Big Bang and, y'know designing new materials at the atomic level. And we thought we were excited about out next desktop.
