Storage Workload Characterization and Consolidation in Virtualized Enviornments

Version 1

    This paper presents workload characterization study of three top-tier enterprise applications using VMware ESX

    server hypervisor. We further separate out different components (for example data, index and redo log in a database)

    of these workloads to understand their behavior in isolation.  We find that most workloads show highly random access

    patterns. Next, we study the impact of storage consolidation on workloads (both random and sequential) and

    their burstiness.
