When enabled, this feature allows an operator to configure fully active-active Metro Volumes across two PowerStore Model T clusters running PowerStoreOS 3.0 or later. The stretched architecture allows workload mobility and cross-site automated load balancing. When a Metro Volume is fully synchronized, it provides concurrent host read and write access to the same Metro Volume on both participating PowerStore clusters. An embedded polarization mechanism protects against a split-brain situation during a failure scenario. After the failure has been corrected, PowerStore starts a self-healing process to turn the Metro Volume back into an active-active state.
