You can delete a data encryption key from a file on the
HDvM - SN computer or from a key management server. This topic provides instructions for deleting data encryption keys from a file or from the key management server.
The VSP Gx00 models and VSP Fx00 models provide a performance-friendly AES-256-XTS encryption capability on the back-end I/O director. This capability protects data at rest on internal storage media (including disk drives and flash drives) attached to those directors. While many levels of encryption are available to the enterprise, protecting data at rest by using the array-level encryption of the storage system provides the following advantages: causes minimal to no performance impact within your operations, remains transparent to existing host servers and switches, shreds storage media by deleting the encryption key, simplifies key management to reduce the risk of the loss of encryption keys and data, and supports logging of encryption and key management events. In addition, many regulations encourage or require encryption of personally identifiable information (PII) and other sensitive data. Array-level encryption handles this type of data as well.
