Client-side Flash Caching for Cloud Systems

Dulcardo Arteaga, Ming Zhao
2014 Proceedings of International Conference on Systems and Storage - SYSTOR 2014  
Client-side flash-based caching has the potential to improve the performance of cloud VM storage by employing flash storage available on the client-side of the storage system to exploit the locality inherent  ...  in VM IOs.  ...  Although the non-volatile nature of flash storage allows writes to be served directly from the cache, how to synchronize the cache with the server has implications on both IO performance and data durability  ...
