Port assignments for FC switches

You need to verify that you are using the specified port assignments when you cable the FC switches.

Ports that are not used for attaching initiator ports, FC-VI ports, or ISLs can be reconfigured to act as storage ports. However, if the supported RCFs are being used, the zoning must be changed accordingly.

If the supported RCFs are used, ISL ports might not connect to the same ports shown here and might need to be reconfigured manually.

Configurations running ONTAP releases should use the port assignments shown here.

Overall cabling guidelines

You should be aware of the following guidelines when using the cabling tables:

The Brocade and Cisco switches use different port numbering:
- On Brocade switches, the first port is numbered 0.
- On Cisco switches, the first port is numbered 1.
The cabling is the same for each FC switch in the switch fabric.
AFA DM7000F and DM7000H storage systems can be ordered with one of two options for FC-VI connectivity:
- Onboard ports 0e and 0f configured in FC-VI mode.
- Ports 1a and 1b on an FC-VI card in slot 1.
AFA DM7100F and DM7100H storage systems use ports 2a and 2b for FC-VI connectivity.
If you have two MetroCluster configurations sharing ISLs, use the same port assignments as that for an eight-node MetroCluster cabling.
The number of ISLs you cable may vary depending on your site's requirements.
See the section on ISL considerations.

Brocade port usage for controllers in a MetroCluster configuration

The following tables show port usage on Brocade switches. The tables show the maximum supported configuration, with eight controller modules in two DR groups. For smaller configurations, ignore the rows for the additional controller modules. Note that eight ISLs are supported only on the Lenovo B6510 FC SAN switch, DB620S, DB630S, and DB720 switches.

Note

Port usage for the Lenovo B6505 FC SAN switch and Lenovo ThinkSystem DB610S 32G FC SAN switch switches in an eight-node MetroCluster configuration is not shown. Due to the limited number of ports, port assignments must be made on a site-by-site basis depending on the controller module model and the number of ISLs and bridge pairs in use.
