Dell EMC Metro node 7.0.1 Product Guide


A metro node is a true cluster architecture. That is, all components are always available and I/O that enters the cluster from anywhere can be serviced by any node within the cluster, while coherency is maintained for all reads and writes.

A metro node cluster provides N–1 fault tolerance, which means that any component failure can be sustained, and the cluster will continue to operate as long as one director survives.

A metro node cluster consists of redundant hardware components.

All hardware resources (CPU cycles, and I/O ports) are pooled.

A two-cluster configuration (Metro) offers true high availability. Operations continue and data remains online even if an entire site fails. It also provides a high availability solution with zero recovery point objective (RPO).
