* HBAs do not support key management for SEDs; third-party host software is responsible for managing the keys.
** The SSD caching feature has been phased out in the new generation of advanced RAID controllers.
Important: The onboard Intel RSTe is not supported by virtualization hypervisors, including VMware vSphere
(ESXi), Linux KVM, Xen, and Microsoft Hyper-V.
