MetroCluster configuration

About MetroCluster configurations  Top

This section discusses how to configure your gateway in a MetroCluster configuration. The MetroCluster configuration expands on the switch-attached cluster configuration.

Also included in this section are rules for zoning switch ports, which is required for MetroCluster configurations.

Supported gateways  Top

The following gateways support the MetroCluster configuration:

Required adapters and hardware for connectivity  Top

You need the following adapters for a MetroCluster:

Connecting a gateway  Top

Configuration A

The following diagram provides an example of how the GF825 and GF940 connect to your storage subsystem for maximum capacity.

Port-to-port connectivity  Top

The following port-to-port scheme supports a maximum of 448 LUNs for the GF940 and a maximum of 512 LUNs for the GF960 in a redundant configuration.

Configuration B

The following diagram provides an example of how the GF960 connects to your storage subsystem for a maximum of 672 LUNs.

Note
HBA connections must never share the same zone as VI-MC connections. Zoning individual HBA connections is not required.

The following illustration shows a MetroCluster configuration with two cluster nodes. Gateways 1 and 3 are partner nodes and gateways 2 and 4 are partner nodes.

Caution
You can attach a standard cluster to either the first or second pair of MetroCluster gateways, but not to both pairs.
