Abstract

In past years, several important storage technologies have emerged and play a vital role in today's cloud services. Two particularly important ones are key-value store and objectbased
cloud storage. In both systems, caching is a crucial component and essential to system performance and user experience.

In this talk, we will present our recent works on optimizing caching efficiency as well as performance in such scenarios. We will first introduce our research efforts on optimizing memory efficiency and exploiting hardware potentials for caching a huge amount of key-value data in flash. Then we will present a cost-aware caching scheme for object-based cloud storage, aiming for improving performance and lowering cost. Our studies show that by carefully exploiting the unique device and workload properties, we can significantly enhance the efficiency and performance of caching for providing high-speed data services at a low cost.
