Rapid Data Locking (RDL)

Some environments require external key management for locking down a forward-deployed array. The Pure Storage FlashArray KMIP RDL solution enables you to use the CryptoHub for this purpose.

​
KMIP RDL

KMIP RDL introduces a secondary user-controllable key that enables unlocking the flash modules of the array. You remotely access the KMIP keys from a KMIP server (such as CryptoHub). Without access to the server, the flash modules cannot be unlocked on power-on.
You can enable RDL during installation or at any time after that. After you enable it, RDL is permanent. It applies to all the SSDs of an array, including those added later.
