Management Ip Address Considerations; Service Ip Address Considerations - IBM Storwize V5010 Manual

2.5.1 Management IP address considerations

Because Ethernet port 1 from each node canister must connect to the LAN, a single
management IP address for the clustered system is configured as part of the initial setup of
the IBM Storwize V5000 Gen2 system.
The management IP address is associated with one of the node canisters in the clustered
system and that node then becomes the configuration node. If this node goes offline (planned
or unplanned), the management IP address fails over to the other node's Ethernet port 1.
For more clustered system management redundancy, you need to connect Ethernet port 2 on
each of the node canisters to the LAN, which allows for a backup management IP address to
be configured for access, if necessary.
Figure 2-10 shows a logical view of the Ethernet ports that are available for the configuration
of the one or two management IP addresses. These IP addresses are for the clustered
system and associated with only one node, which is then considered the configuration node.

2.5.2 Service IP address considerations

Ethernet port 1 on each node canister is used for system management and for service
access, when required. In normal operation, the service IP addresses are not needed.
However, if a node canister problem occurs, it might be necessary for service personnel to log
on to the node to perform service actions.
