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 :-( Also seen this from HPE: http://www8.hp.com/h20195/v2/GetPDF.aspx/c05821090.pdf And this from Intel: https://software.intel.com/en-us/articles/intel-xeon-processor-scalable-family-technical-overview /Peter K
