SDSC was awarded a $12-million grant from the National Science Foundation (NSF) to deploy the new Comet system. Comet will be based on next-generation Intel Xeon processors. In addition to the optimized Aeon Computing 7 PB Lustre filesystem, each node will be equipped with two processors, 128 GB (gigabytes) of traditional DRAM, and 320 GB of flash memory. Comet is designed to optimize capacity for modest-scale jobs, with each rack of 72 nodes having a full bisection InfiniBand FDR interconnect, with a 4:1 bisection interconnect across the racks.
This next-generation Lustre file system pushes the limits of Lustre storage performance, and will be an addition to SDSC's Data Oasis Lustre resource. "We welcome Aeon as a partner in the Comet programme", stated SDSC Deputy Director Richard Moore. "Aeon is a key partner in providing hardware and expertise for our Data Oasis parallel file system, which now serves our Gordon and Trestles systems and will support our Comet cluster when it comes on-line in 2015."
"SDSC pushes the envelope in research computing, and their requirements for high performance, affordability, and maintainability fit perfectly with Aeon's product design approach", stated Jeff Johnson, co-founder of Aeon Computing. "Working closely with SDSC's staff and Comet stakeholders we were able to deliver a very affordable solution that meets the rigorous demands of data-intensive computing and support SDSC's Comet initiative of HPC for the 99%."
The new filesystem will be designed around the Intel next-generation Xeon processor and the latest in SAS storage technology, and is heavily based on commercial off-the-shelf (COTS) components.
