Question 5
A customer wants to set up a Windows 2008 cluster with three nodes, with application data presented from a fifteen module XIV Gen3. All three nodes will run applications under normal operating conditions. Each node has a single dual- port Fibre Channel host bus adapter.
Assuming a dual fabric SAN, how should the cluster nodes be zoned to the XIV within each SAN?
A. ports for all three nodes should be grouped together into a single zone, along with a single XIV port from each available XIV interlace module
B. each host port should be zoned to a single port from two XIV modules, ensuring that the host ports from the remaining two nodes are zoned to different XIV modules
C. each host port should be zoned to a single port from three XIV modules, ensuring that the host port on the second fabric is zoned with a single port from the remaining three XIV modules
D. each host port should be zoned to a single port from one XIV module, ensuring that no other host ports are zoned to the same module
