Which type of MetroCluster is shown in the exhibit?

The exhibit shows a fabric-attached MetroCluster design rather than an IP or stretch design. The output includes FC-VI host adapters, Brocade switch information, FibreBridge devices, and disk shelves connected through FC-to-SAS bridges. Those components are characteristic of a fabric MetroCluster where Fibre Channel switches provide the intersite storage fabric and bridges connect SAS shelves into the FC environment. A two-node stretch MetroCluster would not show the same four-node fabric topology, and MetroCluster IP would use Ethernet-based back-end connectivity rather than FC switches and FC-to-SAS bridges. A four-node stretch MetroCluster would also not use the fabric-switch/bridge arrangement shown in the exhibit. The support engineer must identify topology from the hardware path indicators, not from the node count alone. The presence of FC switches, FC-VI, and ATTO FibreBridge devices makes the topology a four-node fabric-attached MetroCluster.
