text: **11.8.2 IP partnership limitations**
  
  The following prerequisites and assumptions must be considered before IP partnership 
  between two IBM Spectrum Virtualize systems can be established: 
  
  (cid:2) The IBM Spectrum Virtualize systems are successfully installed with V7.2 or later code 
  levels. 
  
  (cid:2) The systems must have the necessary licenses that enable remote copy partnerships to 
  
  be configured between two systems. No separate license is required to enable IP 
  partnership. 
  
  (cid:2) The storage SANs are configured correctly and the correct infrastructure to support the 
  IBM Spectrum Virtualize systems in remote copy partnerships over IP links is in place. 
  
  (cid:2) The two systems must be able to ping each other and perform the discovery. 
  
  (cid:2) TCP ports 3260 and 3265 are used by systems for IP partnership communications. 
  
  Therefore, these ports need to be open. 
  
  (cid:2) The maximum number of partnerships between the local and remote systems, including 
  
  both IP and FC partnerships, is limited to the current maximum that is supported, which is 
  three partnerships (four systems total). 
  
  (cid:2) Only a single partnership over IP is supported. 
  
  (cid:2) A system can have simultaneous partnerships over FC and IP, but with separate systems. 
  
  The FC zones between two systems must be removed before an IP partnership is 
  configured.
