Dimitris Krekoukias writes that NetApp was able to deliver a 1 Terabyte/sec storage solution to LLNL for the pending Sequoia supercomputer by leveraging the Lustre file systems and Engenio disk technology acquired from LSI.
Clearly, if your requirements are big enough, you end up spending a lot less money and needing a lot less rack space, power and cooling by going with a highly performance-dense solution. However, given the requirements of the LLNL, it’s clear that you can’t use just a single E5400 to satisfy the performance and capacity requirements of this use case. What you can do though is use a bunch of them in parallel… and use that massive performance density to achieve about 40GB/s per industry-standard rack with 600x high-capacity disks (1.8PB raw per rack). For even higher performance per rack, the E5400 can use the faster SAS or SSD drives – 480 drives per rack (up to 432TB raw), providing 80GB/s reads/60GB/s writes.
