An enterprise, hybrid RAID solution, specifically designed for NVMe SSDs connected directly to the CPU
Intel® VROC is made possible by the new CPU feature Intel® Volume Management Device, Intel® VMD, a new hardware architecture on Intel® Xeon® Scalable Processors. Intel® VMD enhances drive performance as drives are directly connected to the Intel CPU enabling the lowest latency. Intel® VROC capitalizes on Intel® VMD for a simple software RAID solution that requires no additional hardware.

Server Compatibility
Please refer to the platform QuickSpecs to confirm compatibility for Intel VROC for HPE.
Operating Systems
- − Linux
Notes:
− Customers will need to manually inject the driver when doing an O/S install from IP.
− Please see Intel VROC User Guide for Gen11 for more information.

Drivers
Intel VROC is integrated with the HPE BIOS. The Intel VROC solution has two driver components: the pre-boot, or UEFI driver, and the OS driver. The UEFI driver is embedded in the system BIOS and is referred to as the RSTe NVMe UEFI driver, while the OS driver must be loaded at the OS installation time; both contain version numbers. Refer to the Intel VROC User Guide and Installation Instructions for more information.
Notes: On a system with the Windows OS installed and an Intel VROC virtual drive present, the Windows RSTe OS driver version must not be prior to the RSTe NVMe UEFI driver version, otherwise unexpected behavior may occur.
The RSTe OS driver can be downloaded from the HPE Support Center.
