  4. Storage network provides communication link between the server and the storage array.
  5. Storage array receive command from the server and it perform necessary operation to store the data on physical disks.
The Key Characteristics are as follows:
  1. Availability
  2. Security
  3. Scalability
  4. Performance
  5. Data integrity
