PowerStoreOS versions 3.0 and later support synchronous block replication with the Metro Volume feature. You can use Metro Volume for disaster avoidance, application load balancing, and migration scenarios. This feature provides active-active I/O to a Metro Volume spanned across two PowerStore clusters. It supports FC- or iSCSI-connected VMware ESXi hosts. When Metro Volume is implemented, you can see the details in the PowerStore Manager > Protection > Metro page, as shown in the following figure. You can use this page to monitor, end, pause, and set the local preferred role.
