RAMCloud: Scalable High-Performance Storage Entirely in DRAM

October 3, 2011

Update: missed this tech talk? We've got you covered. Check out the video here.

Come by LinkedIn Headquarters on Wednesday, October 12 for a public tech talk "RAMCloud: Scalable High-Performance Storage Entirely in DRAM". John Ousterhout, Professor of Computer Science at Stanford University, will be presenting. If you are planning to attend, please RSVP here.


In recent years DRAM has played a larger and larger role in storage systems, driven by the demands of large-scale Web applications. However, DRAM is still used primarily in limited or special-purpose ways, such as a cache for some other backing store. In this talk I will describe RAMCloud, a general-purpose storage system where all data lives in DRAM at all times and large-scale systems are created by aggregating the main memories of thousands of commodity servers.

RAMCloud provides durable and available DRAM-based storage for the same cost as volatile caches, and it offers performance 10-100x faster than existing storage systems. By combining low latency and large scale, RAMCloud will enable a new class of applications that manipulate large datasets more intensively than has ever been possible.


John Ousterhout is Professor (Research) of Computer Science at Stanford University. His current research focuses on infrastructure for Web applications and cloud computing. Ousterhout's prior positions include 14 years in industry where he founded two companies (Scriptics and Electric Cloud), preceded by 14 years as Professor of Computer Science at U.C. Berkeley. He is the creator of the Tcl scripting language and is also well known for his work in distributed operating systems and file systems.

Ousterhout received a BS degree in Physics from Yale University and a PhD in Computer Science from Carnegie Mellon University. He is a member of the National Academy of Engineering and has received numerous awards, including the ACM Software System Award, the ACM Grace Murray Hopper Award, the National Science Foundation Presidential Young Investigator Award, and the U.C. Berkeley Distinguished Teaching Award.
