text: Figure 3-9 Example of host connectivity 
  
  In Figure 3-9, the optical distance between Storwize V7000 Node 1 and Host 2 is slightly over 
  40 km (24.85 miles). 
  
  To avoid latencies that lead to degraded performance, avoid ISL hops whenever possible. In 
  an optimal setup, the servers connect to the same SAN switch as the Storwize V7000 nodes. 
  
  **Note:**Before attaching host systems to Storwize V7000, review the Configuration Limits 
  and Restrictions for the IBM System Storage Storwize V7000 at this IBM Support web 
  page.
