text: Figure 12-1 shows an encryption example. Encrypted disks and encrypted data paths are 
  marked in blue. Unencrypted disks and data paths are marked in red. The server sends 
  unencrypted data to a SAN Volume Controller 2145-DH8 system, which stores 
  hardware-encrypted data on internal disks. The data is mirrored to a remote Storwize V7000 
  Gen1 system using Remote Copy. The data flowing through the Remote Copy link is not 
  encrypted. Because the Storwize V7000 Gen1 (2076-324) cannot perform any encryption 
  activities, data on the Storwize V7000 Gen1 is not encrypted.
