Storage Upgrade: DDN SFA770X

The UNT HPC team has deployed another high-speed parallel filesystem affectionately named scratch2. It is running Lustre 2.5.2 on a DDN SFA7700X storage appliance. The SFA7700X is a hybrid flash storage appliance, purpose-built for Big Data requirements that enables our researchers to continue solving bigger problems. This filesystem has 1.4PB total available and can sustain speeds of up to 10GB/s over FDR Infiniband. For more info see: http://www.ddn.com/products/lustre-file-system-exascaler/
