Abstract

High speed networks allow machines to access remote memory faster than local disks. Cooperative Caching exploits this phenomenon, using I/O caches of remote workstations as an extra level of memory hierarchy. Most research has focused on improving the read performance of Cooperative Caching, resulting in disk writes becoming a performance bottleneck. We propose a write-back mechanism called "Distributed, Efficient and Reliable (DEFER) Cooperative Cache" that uses replication and logging to improve reliability and performance. We present three strategies based on this architecture, and evaluate their performance using simulations. The simulations indicate a maximum speedup of 11.5x over the write-through baseline.
