Metro node overview
Metro node virtualizes data that is on storage arrays to create dynamic, distributed, and highly available data centers.
Use metro node to:
● Move data nondisruptively between Dell EMC PowerStore, Unity XT and other third-party storage arrays without any
downtime for the host.
Metro node moves data transparently, and the virtual volumes retain the same identities and the same access points to the
host. There is no need to reconfigure the host.
● Protect data in the event of disasters or failure of components in your data centers.
With metro node, you can withstand failures of storage arrays, cluster components, an entire site failure, or loss of
communication between sites (when two clusters are deployed) and still keep applications and data online and available.
With metro node, you can transform the delivery of IT to a flexible, efficient, reliable, and resilient service.

Metro node addresses these two primary IT needs:
● Mobility: Metro node moves applications and data between different storage installations:
○ Within the same data center or across a campus (metro node Local)
○ Within a geographical region (metro node Metro)
● Availability: Metro node creates high-availability storage infrastructure across these same varied geographies with
unmatched resiliency.
