Cabling the FC-VI adapter and ISL in a shared-switches configuration
Cabling in a shared-switches configuration involves cabling the FC-VI and HBA ports to the Brocade switches, and cabling the FibreBridge 6500N bridges to the Brocade switches and the SAS disk shelves.
In a shared-switches configuration, four nodes join together to form two fabric-attached MetroCluster configurations. In the illustration, FMC1-1 and FMC1-2 form one fabric-attached MetroCluster configuration, FMC1. FMC2-1 and FMC2-2 form another fabric-attached MetroCluster configuration, FMC2.
The following illustration shows the shared-switches configuration:
Connect the ports of the FC-VI adapter to primary and secondary switches for both the storage systems in the MetroCluster configuration.
In the illustration, the FC-VI adapter from storage system FMC1-1 connects to primary switch S1 and secondary switch S2 through port 0.
The FC-VI adapter from storage system FMC2-1 connects to primary switch S2 and secondary switch S1 through port 1.
Connect the ports of the HBA to the primary and secondary switches.
In the illustration, the HBA from storage system FMC1-1 connects to primary switch S1 and secondary switch S2 through ports 2 and 8.
The HBA from storage system FMC2-1 connects to primary switch S2 and secondary switch S1 through ports 3 and 9.
If you are using the FibreBridge 6500N bridge, complete the following steps:
For details about installing FibreBridge 6500N bridge as part of your MetroCluster configuration, see Configuring a MetroCluster system with SAS disk shelves and FibreBridge 6500N bridges, available at the NetApp Support Site.
- Connect the FibreBridge 6500N bridge to the switches.In the illustration, the FibreBridge bridge FB1-1 of the FMC1-1 connects to switch S1 through port 5.
- Connect the FibreBridge 6500N bridge to the disk shelves.
- Repeat steps 1 through 3 at another site.
When cabling at both the sites are complete, connect an ISL cable to a port on each switch.
In the illustration, the fabric containing switches S1 and S3 has two ISLs and the fabric containing switches S2 and S4 also has two ISLs.
The switch S1 connects to switch S3 and switch S2 connects to switch S4 through ports 17 and 18.
Configure the traffic isolation zone on the switches. In the illustration, FCVI_TI_S1S3 refers to the traffic isolation zone created using ports 0, 1, and 17 of switches S1 and S3. Similarly, FCVI_TI_S2S4 refers to the traffic isolation zone created using ports 0, 1, and 17 of switches S2 and S4.For more information, see the Fabric-attached MetroCluster Systems Brocade Switch Configuration Guide.
After cabling the shared-switches configuration, you must define the preferred primary port.
