The Intel® VROC family of products is comprised of several components that provide a complete platform solution. The following is a list of the key features that are supported on the Intel® VROC (Non-VMD NVMe* RAID) sub-product. To learn about the key features supported by other Intel® VROC sub-products, refer to the following resources:
The Intel® VROC family of products includes RAID support for Intel NVMe* drives on platforms outlined in the Intel® VROC (SATA RAID) Platform Support Matrix section available in the Intel® Virtual RAID on CPU (Intel® VROC) Platforms and Chipsets Support List. This support is provided by the Intel® VROC (Non-VMD NVMe* RAID) package. The Intel® VROC (Non-VMD NVMe* RAID) package provides a data RAID solution on Intel NVMe* Solid-State Drives (SSDs) plugged into a PCIe slot managed by an Intel CPU that does not contain Intel® Volume Management Device (Intel® VMD) technology.
| Note | Intel® VROC (Non-VMD NVMe* RAID) is no longer included in the Intel® VROC software package for Windows*. If support for this sub-product is required, use the Intel® VROC 7.x release family. |
The Intel® VROC (Non-VMD NVMe* RAID) package provides support for Intel NVMe* SSDs in the following usages:
The Intel® VROC (Non-VMD NVMe* RAID) package does not support booting from a RAID volume, so Intel® VROC (Non-VMD NVMe* RAID) does not contain a Pre-OS UEFI driver. It is not required, nor it is needed.
The Intel® VROC installation utility will only install Intel® VROC (Non-VMD NVMe* RAID) on those platforms outlined in the Intel® VROC (SATA RAID) Platform Support Matrix section available in the Intel® Virtual RAID on CPU (Intel® VROC) Platforms and Chipsets Support List.
The Intel® VROC (Non-VMD NVMe* RAID) package provides a private API that allows user-space applications to send and execute NVMe* commands to remapped PCIe NVMe* devices. This new API is based on the new IOCTL definition to implement NVMe* pass-thru channel.
This is the list of supported Intel NVMe* SSDs included with the Intel® VROC (Non-VMD NVMe* RAID) release. This list only applies to Intel® VROC (Non-VMD NVMe* RAID). It does not apply to Intel® VROC (VMD NVMe* RAID). Consult the Intel® Virtual RAID on CPU (Intel® VROC) NVMe* Drives Support List for a list of supported NVMe* SSDs in Intel® VROC (VMD NVMe* RAID).
The Intel® VROC (Non-VMD NVMe* RAID) package provides support for the creation of RAID volumes across multiple Intel NVMe* SSD controllers when attached to PCIe slots managed by the CPU. When installing the Intel® VROC (Non-VMD NVMe* RAID) package, ensure that there are no Intel NVMe* SSDs attached to PCIe slots managed by the Platform Controller Hub (PCH) (refer to the platform's vendor documentation for details). When there are Intel NVMe* SSDs attached to the PCH, the Intel® VROC (Non-VMD NVMe* RAID) installation process will install the Intel® VROC (Non-VMD NVMe* RAID) driver against those devices. Those devices will show up in the Intel® VROC Graphical User Interface (GUI) application. The Intel® VROC (Non-VMD NVMe* RAID) package should not impact the operation of these devices in this configuration.
Intel® VROC (Non-VMD NVMe* RAID) does not support spanning NVMe* RAID volumes across CPU and PCH PCIe slots.
The Intel® VROC (Non-VMD NVMe* RAID) package has the following feature limitations:
