You must configure each of the Brocade switch fabrics in the MetroCluster configuration.
Before you begin
- You must have a PC or UNIX workstation with Telnet or Secure Shell (SSH) access to the FC switches.
- You must be using four supported Brocade switches of the same model with the same Brocade Fabric Operating System (FOS) version and licensing.
NetApp Interoperability Matrix Tool
In the IMT, you can use the Storage Solution field to select your MetroCluster solution. You use the Component Explorer to select the components and ONTAP version to refine your search. You can click Show Results to display the list of supported configurations that match the criteria.
- The four supported Brocade switches must be connected to two fabrics of two switches each, with each fabric spanning both sites.
- Each storage controller must have four initiator ports available to connect to the switch fabrics. Two initiator ports must be connected from each storage controller to each fabric.
Note: You can configure
FAS8020,
AFF8020,
FAS8200, and
AFF A300 systems with two initiators ports per controller (a single initiator port to each fabric) if all the following criteria are met:
- There are fewer than four FC initiator ports available to connect the disk
storage and no additional ports can be configured as FC initiators.
- All slots are in use and no FC initiator card can be added.
About this task
- You should enable Inter-Switch Link (ISL) trunking when it is supported by the links.
Considerations for using TDM/WDM equipment with fabric-attached MetroCluster configurations
- All ISLs must have the same length and same speed in one fabric.
Different lengths can be used in the different fabrics. The same speed must be used in all fabrics.
- Metro-E and TDM (SONET/SDH) are not supported, and any non-FC native framing or signaling is not supported.
Metro-E means Ethernet framing or signaling occurs either natively over a Metro distance or through some time-division multiplexing (TDM), multiprotocol label switching (MPLS), or wavelength-division multiplexing (WDM).
- TDMs, FCR (native FC Routing), or FCIP extensions are not supported for the MetroCluster FC switch fabric.
- Certain switches in the MetroCluster FC switch fabric support encryption or compression, and sometimes support both.

- The Brocade Virtual Fabric (VF) feature is not supported.
- FC zoning based on domain port is supported, but zoning based on
worldwide name (WWN) is not supported.
