Design Tradeoffs in Applying Content Addressable Storage to Enterprise-scale Systems Based on Virtual Machines

This talk presents an analysis of usage data from a live deployment of an enterprise client management system based on virtual machine (VM) technology. Over a period of seven months, twenty-three volunteers used VM-based computing environments hosted by the system and created over 800 checkpoints of VM state, where each checkpoint included the virtual memory and disk states. Using this data, we present the design tradeoffs in applying content addressable storage (CAS) to such VM-based systems. In particular, we explore the impact on storage requirements and network load of different privacy properties and data granularities in the design of the underlying CAS system. This study demonstrates that relaxing privacy can reduce the resource requirements of the system, and identifies designs that provide reasonable compromise between privacy and resource demands.

Partho Nath is a PhD student working with Dr. Anand Sivasubramaniam at Penn State University. His research interests include high performance storage systems, file-systems and virtual machines. He is currently exploring benefits of applying content addressable storage (CAS) to the above areas.
