A company has three Dell EMC Isilon X2000 nodes and needs to configure two subnets on the cluster. The production subnet will only use a 10 GigE-1 port from each node. The second subnet will use both ext-1 and ext-2 ports on each node. The company will access each subnet with its SmartConnect zone name.
Given that the second subnet is isolated with no route to the DNS server, how many IP addresses are needed for each subnet to accommodate the requirements?
