  Although systems can have up to three partnerships, volumes can be part of only one remote 
  copy relationship, for example A → B. 
  
  **System partnership intermix:**All of the preceding topologies are valid for the intermix of 
  the IBM SAN Volume Controller with the Storwize V7000 if the Storwize V7000 is set to the 
  replication layer and running IBM Spectrum Virtualize code 6.3.0 or later.
