HLRE-3 "Mistral"

The first phase of Mistral, the high performance computing system for Earth system research (HLRE-3), consists of computer components by Atos/Bull, a disk storage system by Xyratex/Seagate and high performance network switches by Mellanox. These components are distributed over 79 racks weighing up to or even more than a ton, which are connected by bundles of fiber fabric.
