Connecting Cluster Cables

The controller cluster interface card provides redundant links through I/O ports that enable two controllers to communicate with each other. See Controller Cluster I/O Ports for details about the cluster interface card.

Cluster cabling must be done before powering on either controller, and all cluster interface card links must be established before configuration can proceed.

Ethernet cables for connecting clustered controllers are supplied. If you supply your own Ethernet cables, ensure the cables are straight-through and the correct length, Category 6A for Oracle ZFS Storage ZS11-2 and ZS9-2 controllers, and Category 5 or better for all other controllers.

The following sections describe how to connect cluster cables for different controllers.
