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.
