NetApp Aggregate Encryption (NAE) in ONTAP
Previously in a post I explained how to set up an encrypted volume using an encryption key manager (KMS) specifically from the company HyTrust . In this specific case each volume is encrypted individually using independent keys. A disadvantage of this method is that it affects the possibility of increasing the efficiency levels of data reduction such as compression, compaction and de-duplication (cross-volume-dedupe). To eliminate this disadvantage the NetApp gurus came up with the idea of applying the encryption feature at the aggregate level by allowing volumes residing within the same aggregate to share the encryption key....
