Hot off the press!
One of the most notable feature announcements of VMware Virtual SAN 6.1 is the availability of stretched cluster deployment. This allows the Virtual SAN customer to configure two geographically located sites, while synchronously replicating data between the two sites. This provides high availability and protection against a single site failure.
This white paper provides an in-depth performance analysis 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.
We hope you will enjoy reading and learning more about stretched clusters as much as we do!
