Dell Metro node Appliance

Synchronous active-active replication over metro or local distances

Metro node overview

Enable your automated business continuity solution with zero RPO and RTO with the metro node appliance. True active-active synchronous replication over metro distances with multi-site dual access gives organizations full confidence that their data will always be available and accessible, and there is no time associated with recovery. The metro node appliance also supports local configurations for continuous application availability, data mobility to non-disruptively relocate workloads, and enables storage technology refresh without application downtime.

Metro node key features

• Zero RPO and RTO – Metro node is an active-active solution, which means it actively mirrors data across metro distance. Metro node provides a Recovery Point Objective (RPO) equal to zero, meaning there will be zero data loss. Metro node also provides a zero Recovery Time Objective (RTO), which means the time to recover is zero time or immediately.

• Decision Time Objective (DTO) – DTO is how much time is needed to make the decision to failover. With metro node’s Metro Synchronous replication and cluster witness server, RPO, RTO and DTO are equal to zero.

• Automatic Site Failover – The cluster witness server helps mitigate a site failure.

• Active-Active Metro – Metro node provides optimized data access from both sites for increased performance.

• Avoid Degradation to Array Performance – Metro node replication is built-in to the appliance without any array overhead increases.

• No Additional Host Software – Metro node is self-contained and does not require any software to be deployed on the hosts or a host reboot.

• Multi-Platform Support – Metro node enables replication between different Dell arrays and supports many 3rd party arrays.

• Volume/LUN Level Granularity – Metro node allows the replication of specific LUNs for application-level granularity, significantly reducing TCO and improving flexibility by giving customers the choice of which workloads to replicate.

• Non-disruptive Addition of Consistency Groups – Metro node supports consistency group add/delete operations without disruption and provides operational flexibility with zero downtime.
