text: **2.6 Business continuity**
  
  Business continuity and continuous application availability are among the top requirements 
  for many organizations. Advances in virtualization, storage, and networking have made 
  enhanced business continuity possible. 
  
  Information technology solutions can now manage planned and unplanned outages, and 
  provide the flexibility and cost efficiencies that are available from cloud-computing models. 
  
  **2.6.1 Business Continuity with HyperSwap**
  
  The HyperSwap high availability feature in the IBM Spectrum Virtualize software allows 
  business continuity in the event of hardware failure, power failure, connectivity failure, or 
  disasters, such as fire or flooding. The HyperSwap feature is available on the IBM SAN 
  Volume Controller, IBM Storwize V7000, IBM Storwize V7000 Unified, and IBM Storwize 
  V5000 products. 
  
  The HyperSwap feature provides highly available volumes accessible through two sites at up 
  to 300 km (186.4 miles) apart. A fully independent copy of the data is maintained at each site. 
  When data is written by hosts at either site, both copies are synchronously updated before the 
  write operation is completed. The HyperSwap feature automatically optimizes itself to 
  minimize data transmitted between sites and to minimize host read and write latency.
