Leading energy efficiency: average $100K in annual savings for 10 Tflps compute power.
Enhanced serviceability, blade based platform that is monitored and managed at the blade, chassis, rack levels.
Fully redundant system components, hot-swappable blades.
SGI Platform Manager (name TBD) provides multi-level management across complete Carlsbad system.
SGI “out of the box” deployment, backed by SGI world-class support and service, for immediate productivity.
10 Tflp of compute power “up and running” user apps in a day
Standards-based – Intel Xeon Processor technology, certified Linux, Microsoft Windows CCS
