3.2.2 IBM N62x0 MetroCluster / gateway models

This section gives a brief description of the MetroCluster feature. For more information, see
Chapter 8, "MetroCluster" on page 101.
Supported MetroCluster N62x0 configuration
The following MetroCluster two-chassis configurations are supported:
Each chassis single-enclosure stand alone
• IBM N6210 controller with blank. The N6210-C20 with MetroCluster does ship the
• IBM N6240 controller with IOXM
Two chassis with single-enclosure HA (twin)
• Supported on IBM N6240 model
Fabric MetroCluster requires EXN4000 disk shelves or SAS shelves with SAS FibreBridge
(EXN3000 and EXN3500)
Gateway Models are supported on both models, but have these requirements:
A 4 port/4 Gb FC adapter required for IBM Gateway N6240 array attach
N6210 Gateway is limited to one LUN group from a single array
FCVI card and port clarifications
In many stretch MetroCluster configurations, the cluster interconnect on the NVRAM cards in
each controller is used to provide the path for cluster interconnect traffic. The N60xx and
N62xx series offer a new architecture that incorporates a dual-controller design with the
cluster interconnect on the backplane.
The N62x0 ports c0a and c0b are the ports you need to connect to establish controller
communication. Use them to enable NVRAM mirroring after you set up a dual-chassis HA
configuration (that is, N62xx with IOXM). Those ports are not capable of running standard
Ethernet or the Cluster-Mode cluster network.
second chassis, but does not include the VI card any more.
