Specify the number of unswitched node-to-node connections your cluster has. Again, this will depend on which topology you implement, as follows:
Two-node cluster - nonstriped, set
Number of Direct Links in cluster = 1
Two-node cluster - striped, set
Number of Direct Links in cluster = 2
Three- or four-node cluster - either nonstriped or striped, set
Number of Direct Links in cluster = 0
