Cabling the cluster adapters

Cluster cabling differences

Your cluster arrives with one of four different types of cluster adapters, depending on the configuration you are installing. The following table lists the different supported cluster adapters and the major differences between them.

See the System Configuration Guide at http://now.netapp.com for current information about supported cluster adapters for specific storage systems.

Cluster adapter type	General characteristics
Cluster interconnect adapter	No longer shipped with new systems. Does not support mirrored clusters.
IB cluster adapter	Uses an optical cable up to 500 meters long. Requires two SC/SC cables and GBICs for distances over 30 meters (purchased separately).
VI cluster adapter (Rev B)	Uses an optical cable up to 500 meters long. Requires an LC/LC cable for distances over 30 meters (purchased separately).
VI-MC cluster adapter	Connects directly to Fibre Channel switches. Requires two SC/SC cables (purchased separately).

Cabling the IB cluster adapter

To cable the IB cluster adapters, complete the following steps.

Step	Action
1	Plug one end of the optical cable into one of the local node's IB cluster adapter ports, then plug the other end into the partner node's corresponding IB cluster adapter port. Attention You must not cross-cable the cluster interconnect adapter. Cable the local node ports only to the identical ports on the partner node.
2	Repeat Step 1 for the remaining port on the cluster adapter.
3	Gently pull on the cable ends to ensure that they are properly seated.
4	Go to Chapter 4, Configuring a Cluster.

Cabling the VI cluster adapter

To cable the VI cluster adapters, complete the following steps, using the diagram for reference.

Step	Action
1	Plug one end of the optical cable into the GBIC of the local node's VI cluster adapter, then plug the other end into the partner node's corresponding VI cluster adapter. Attention You must not cross-cable the cluster interconnect adapter. Cable the local node ports only to the identical ports on the partner node.
2	Go to Chapter 4, Configuring a Cluster.

Step

Action

Plug one end of the optical cable into the GBIC of the local node's VI cluster adapter, then plug the other end into the partner node's corresponding VI cluster adapter.

Attention
You must not cross-cable the cluster interconnect adapter. Cable the local node ports only to the identical ports on the partner node.
