Data at Rest Encryption (D@RE)

  • D@RE provides hardware-based, on-array, back-end encryption, and data reduction is performed as an inline process. Data is passed through data reduction hardware before being sent through the encryption hardware. Therefore, data is compressed, deduplicated, or both before being encrypted. On a D@RE enabled system, data encrypted on disk has already been compressed, deduplicated, or both.
