text: The cost reductions that are achieved through software can facilitate the transition to all Flash 
  storage. Flash storage has lower operating costs, lower power consumption, higher density, 
  and are cheaper to cool. However, the cost of Flash storage is still higher than disk storage. 
  
  With technologies, such as DRP, the cost difference can be reduced to a point where an all 
  Flash solution is feasible. The first benefit of DRP is in the form of storage savings because of 
  deduplication. The deduplication process identifies unique data patterns, and stores the 
  signature of the data for reference when writing new data. If the signature of the new data 
  matches a signature, the new data is not written to disk, but instead a reference to the stored 
  data is written. The same byte pattern can occur many times, which results in the amount of 
  data that must be stored being greatly reduced. 
  
  The second benefit of DRP comes in the form of performance improvements because of 
  compression. Although deduplication aims to identify the same data elsewhere in the storage 
  pool and create references to the duplicate data instead of writing extra copies, compression 
  is trying to reduce the size of the host data that is written. 
  
  Compression and deduplication are not mutually exclusive, one, both, or neither features can 
  be enabled. If the volume is de-duplicated and compressed, data is de-duplicated first and 
  then compressed. Therefore, deduplication references are created on the compressed data 
  stored on the physical domain.
