Advantages of fabric-attached MetroCluster configurations

Fabric-attached MetroCluster configurations provide the same advantages of stretch MetroCluster configurations, while also enabling the physical nodes to be physically distant from each other.

The advantages of a fabric-attached MetroCluster configuration over a stretch MetroCluster configuration include the following:

  • The two halves of the configuration can be more than 500 meters apart, which provides increased disaster protection.
  • For fabric-attached MetroCluster configurations with FAS systems, disk shelves and nodes are not connected directly to each other, but are connected to a fabric with multiple data routes, ensuring no single point of failure.
  • For fabric-attached MetroCluster configurations with systems using array LUNs, the storage arrays and nodes are not connected directly to each other, but are connected to a fabric with multiple data routes, ensuring no single point of failure.
