Dell EMC Metro node 7.0.1 Product Guide

Metro node Metro

Metro node Metro consists of two metro node clusters connected by inter-cluster links with not more than 10ms Round Trip Time (RTT). Metro node Metro:

• Transparently relocates data and applications over distance, protects your data center against disaster.

  Manage all of your storage in both data centers from one management interface.

• Mirrors your data to a second site, with full access at near local speeds.

Deploy metro node Metro within a data center for:

• Additional virtual storage capabilities beyond that of a metro node Local.
• Higher availability.

  Metro clusters can be placed up to 100 km apart, allowing them to be located at opposite ends of an equipment room, on different floors, or in different fire suppression zones; all of which might be the difference between riding through a local fault or fire without an outage.

Deploy metro node Metro between data centers for:

• Mobility: Redistribute application workloads between the two data centers.
• Availability: Applications must keep running in the presence of data center failures.
• Distribution: One data center lacks space, power, or cooling.

Combine metro node Metro virtual storage and virtual servers to:

• Transparently move virtual machines and storage across synchronous distances.
• Improve utilization and availability across heterogeneous arrays and multiple sites.

Distance between clusters is limited by physical distance, by host, and by application requirements. Metro node Metro clusters contain additional I/O modules to enable the inter-cluster WAN communication over IP.
