Intel FAQ had the following nugget of info but I've yet to try it
myself..
What is the difference between Intel® VROC and Linux* MD RAID?
Intel® VROC for Linux* is built upon MD RAID, and the Intel VROC team
has an MD RAID maintainer on the team. However, Intel VROC has the
following extra features:
* Provides UEFI HII and UEFI Shell command line RAID management
* Provides webpage-based, remote RAID management and RESTful APIs
* Fully validated and supported with Purley platform and
industry-select
* SSDs Provides hotfix/patch to specific customer issue on supported OS
Seems a mess of licensing and enabling too :-(
