We have a lot of clusters in our company. Many have two IP addresses in an application, one for prod and one for backup, each on a different adapter. E.g we have SQL instances like this.
Looking at the failover cluster manager, some applications have two ip subnet addresses in the network name resource(in the ip addresses section)
Some applications have the second backup ip address in as in ip address resource, located in the other resources section.
It made me wonder, what is the difference between putting two IP subnets addresses in the network name resources ip addresses section, versus putting the second IP address in as an IP resource in other resources. Both seem to work. Is there actually any difference, or is it purely cosmetic/graphical?
This distinction was never seen on older 2003 clusters, as every ip address was just an ip resource, with the network name having dependency on it.
