Table 1. General metro node use cases and benefits
General use cases	Benefits
Mobility	Migration: Move data and applications without impact on users. Virtual Storage federation: Achieve transparent mobility and access within a data center and between data centers.
Availability	Resiliency: Mirror across arrays within a single data center or between data centers without host impact. This increases availability for critical applications.

For all metro node deployments, do the following:

Presents storage volumes from back-end arrays to metro node engines.
Federates the storage volumes into hierarchies of metro node virtual volumes with user-defined configuration and protection levels.
Presents virtual volumes to production hosts in the SAN through the metro node front-end.
