text: **Tip:**Create an alias for the I/O Group port set. This step makes it easier to correctly zone 
  hosts to the correct set of I/O Group ports. It also makes host group membership visible in 
  the FC switch configuration. 
  
  The use of this schema provides four paths to one I/O Group for each host, and helps to 
  maintain an equal distribution of host connections on Storwize V7000 ports. 
  
  **Tip:**To maximize performance from the host point of view, distribute volumes that are 
  mapped to each host between both I/O Group nodes.
