VMware Virtual SAN Stretched Cluster - Performance and Best Practices

Version 1

    This white paper examines the performance aspects of a Virtual SAN stretched cluster deployment. Specifically, it examines the overhead of synchronously replicating data across two geographical sites by benchmarking against a regular, single site Virtual SAN cluster deployment. Failure scenarios of a single hard disk and entire site failure are considered. The Virtual SAN stretched cluster can handle both failure scenarios robustly.
