interruption. If interruption occurs, the remaining cluster node will assume the
other node has gone down and initiate a failover. A second cluster heartbeat path
is often recommended as a redundant path. The redundant path is often done over
one of the remaining network segments and is not dedicated.
The client data segments of a cluster must reside on identical network segments
for each node. As illustrated in
, Eth2 from both nodes is shown on the
same segment. This co-location on the same segment allows cluster resources
such as file shares to failover to the second node and continues to provide
availability to the resources. The failed resource will have the same IP address
after the failover and therefore must have a port corresponding to the identified
subnet of the IP address present on both nodes.
The NAS e7000 v2 supports the use of NIC teaming in clustered configurations.
All previous caveats from the NAS e7000 v2 single node deployment on networks
section still apply.
