  3. 
  In the Licensed Functions pane, you can view or set the licensing options for the IBM 
  Storwize V7000 for the following elements (limits are in TiB): 
  
  – External Virtualization 
  
  Specifies the number of enclosures of external storage systems that are attached to 
  your IBM Storwize V7000. Data can be migrated from storage systems to your system 
  that uses the external virtualization function within 45 days of purchase of the system 
  without purchase of a license. After 45 days, any ongoing use of the external 
  virtualization function requires a license for each enclosure in each external system. 
  
  The system does not require an external virtualization license for external enclosures 
  that are being used only to provide managed disks for a quorum disk and are not 
  providing any capacity for volumes. 
  
  – Remote Mirroring Limit 
  
  The remote-mirroring function configures a relationship between two volumes. This 
  function mirrors updates that are made to one volume to another volume. The volumes 
  can be in the same system or on two different systems. 
  
  The remote-mirroring function is licensed per enclosure. It allows the use of 
  remote-mirroring functions on the total number of enclosures that are licensed.
