text: **10.2 Thin provisioned volumes**
  
  In a shared storage environment, thin provisioning is a method for optimizing the usage of 
  available storage. It relies on the allocation of blocks of data on demand versus the traditional 
  method of allocating all of the blocks up front. This method eliminates almost all white space, 
  which helps avoid the poor usage rates (often as low as 10%) that occur in the traditional 
  storage allocation method where large pools of storage capacity are allocated to individual 
  servers but remain unused (not written to). 
  
  Thin provisioning presents more storage space to the hosts or servers that are connected to 
  the storage system than is available on the storage system.
