There's a very nice story in the latest issue of the Communications of the ACM (CACM) about Moneta, Onyx, and the future of storage performance. It features discussions with both Steve and Rajesh as well as our good friend Allan Snavely from the San Diego Supercomputing Center. It does a great job of laying out the future for Moneta-like systems and what they mean for software.
Laura Grupp is the lead author on our FAST paper that describes the future of scaling for enterprise-class SSDs. Based on the scaling trends, reliability requirements, and the economic constraints, the paper paints a picture of how SSD capacity will continue to increase (or not) as further pressure on flash density reduces performance and reliability.
The paper was in collaboration with John Davis at Microsoft Research.
Well done, Laura!
Lawrence Livermore National Laboratory's (LLNL) Lawrence Scholar Program (LSP) is a competitive program that provides graduate students with the opportunity to work closely with LLNL researchers.
Arup will be working with Maya Gokhale's group to understand the role of non-volatile memories in data-intensive computing problems. It's going to be a great opportunity to strength ties between the two labs!
Way to go, Arup!
