Metro sync DR (Disaster Recovery) provides two-way synchronous data replication between IBM® Spectrum Fusion™ HCI clusters installed at two sites. In the event of a site disaster, applications can be failed over to the second site. The replication between the sites is synchronous, hence, the Metro sync DR solution is only available for metropolitan distance data centers with 40 millisecond latency or less.
This IBM Redpaper Redpaper publication will help you install and configure the new Metro sync DR function (MetroDR). The use case will show the end to end process with the failover and failback of the WordPress application.
