text: IBM Spectrum Virtualize includes the following key features: 
  
  (cid:2) Simplified storage management by providing a single management interface for multiple 
  storage systems, and a consistent user interface for provisioning heterogeneous storage. 
  
  (cid:2) Online volume migration. IBM Spectrum Virtualize enables moving the data from one set 
  of physical drives to another, in a way that is transparent for the storage consumers and 
  without over-straining the storage infrastructure. The migration can be done within a 
  specific storage system (from one set of disks to another), or across storage systems. 
  Either way, the host that uses the storage is not aware of the operation, and no downtime 
  for applications is needed. 
  
  (cid:2) Enterprise-level Copy Services functions. Performing Copy Services functions within the 
  IBM Spectrum Virtualize removes dependencies on capabilities and intercompatibility of 
  the virtualized storage subsystems. Therefore, it enables the source and target copies to 
  be on any two virtualized storage subsystems. 
  
  (cid:2) Improved storage space usage because of pooling of resources across virtualized storage 
  systems. 
  
  (cid:2) Opportunity to improve system performance as a result of volume striping across multiple 
  
  virtualized arrays or controllers and the benefits of cache that is provided by IBM 
  Spectrum Virtualize hardware.
