Typically SvSAN cluster deployments reside in a single physical location either in the same rack, equipment room or site, with cluster nodes usually separated by a relatively short distance. However, it is possible to separate the cluster nodes over greater distances while maintaining synchronous data replication, effectively creating a “stretched” cluster configuration. Stretched clusters introduce another level of resiliency, protecting against site failures such as fire, flood, theft, power loss, etc. as well as protection from server and storage failures. How far can the SvSAN nodes and the neutral storage host (NSH) be separated though before performance is significantly impacted?
