  **11.6.12 Global Mirror features**
  
  IBM Spectrum Virtualize Global Mirror supports the following features: 
  
  (cid:2) Asynchronous remote copy of volumes that are dispersed over metropolitan-scale 
  distances. 
  
  (cid:2) IBM Spectrum Virtualize implements the Global Mirror relationship between a volume pair, 
  with each volume in the pair being managed by an IBM Spectrum Virtualize system. 
  
  (cid:2) IBM Spectrum Virtualize supports intracluster Global Mirror where both volumes belong to 
  the same system (and I/O Group). 
  
  (cid:2) An IBM Spectrum Virtualize system can be configured for partnership with 1 - 3 other 
  
  systems. For more information about IP partnership restrictions, see 11.8.2, “IP 
  partnership limitations” on page 550. 
  
  (cid:2) Intercluster and intracluster Global Mirror can be used concurrently, but not for the 
  
  same volume.
