The rails are also brand new, … Read moreSoon … 12g goodness in new chassis
A 1.2PB single mount point Scalable Informatics Unison system, running an MPI job (io-bm) that just dumps data as fast as the little Infiniband FDR network will allow. Our test case. Write 2TB (2x overall system memory) to disk, across 48 procs. No SSDs in the primary storage. This is just spinning rust, in a … Read moreMassive, unapologetic, firepower: 2TB write in 73 seconds
