Supported fabric-attached MetroCluster configuration with disks and array LUNs

When configuring a MetroCluster configuration with disks and storage arrays, you need to follow the best practice recommendations for how to connect the hardware components.

The key points to remember about connections in a fabric-attached MetroCluster configuration with disks and storage arrays are as follows:

  • You use the same switches to connect a Data ONTAP system to the FibreBridge 6500N bridges and the storage array.
  • You use different switch ports for the connections to the FibreBridge 6500N bridges than for the connections to the storage array.
  • You use different FC initiator ports on the Data ONTAP system for the switch ports connecting to the FibreBridge 6500N bridges than for the switch ports connecting to the storage array.

    If your system does not have enough FC initiator ports for separate connections to the bridges and storage array, you must add some FC initiator ports.

The Interoperability Matrix at support.netapp.com contains information about the hardware components that are supported for a MetroCluster configuration with storage arrays. Configuring a MetroCluster system with SAS disk shelves and FibreBridge 6500N bridges contains information about the connections between the FibreBridge 6500N bridges and the disk shelves.

The following block diagram shows a fabric-attached MetroCluster configuration that uses only array LUNs:

The following block diagram shows the same fabric-attached MetroCluster, but with disks as well. Notice that the same switches are used for access to the storage arrays and the FibreBridge 6500N bridges, but different switch ports are used for the bridges and the storage arrays. Also notice that different FC initiator ports are used for the two types of storage:
