9 Working with maxCrypto™ Devices
Microchip Smart Storage Controllers support an advanced controller-based encryption (CBE) technology called maxCrypto™. It provides an enterprise-class encryption solution that protects sensitive data on storage connected directly to your controller.

maxCrypto supports two roles for managing encryption services:
A Crypto Officer (Admin) role that can perform all encryption operations
A User role with reduced privileges
maxCrypto allows you to selectively encrypt arrays and logical drives, regardless of RAID level; create storage spaces with mixed encrypted and plaintext volumes; and convert plaintext volumes to encrypted volumes.
Note: Encryption of non-RAID volumes (such as physical, raw, or
pass-through devices) is not supported. Consequently, HBAs and
controllers operating in HBA Mode do not support maxCrypto.
