Intel® Virtual RAID on CPU (Intel® VROC) is an enterprise RAID solution that unleashes the performance of NVMe* SSDs. Intel® VROC is enabled by a feature in Intel® Xeon® Scalable processors called Intel® Volume Management Device (Intel® VMD), an integrated controller inside the CPU PCIe root complex. NVMe* SSDs are directly connected to the CPU, allowing the full performance potential of fast storage devices to be realized. Intel® VROC enables these benefits without the complexity, cost, and power consumption of traditional hardware RAID host bus adapter (HBA) cards placed between the drives and the CPU.
Intel® VROC is a complete RAID solution that includes:
Intel® VROC Product Brief | Read the product brief to learn more about Intel® VROC. |
The Intel® VROC family of products provides enterprise RAID solutions for both NVMe* and SATA devices for the enterprise servers, workstations, and some high-end desktops. The product family includes the following three products:
Intel® VROC is a high-level blanket product reference for Intel® VROC (VMD NVMe* RAID), Intel® VROC (SATA RAID) and Intel® VROC (Non-VMD NVMe* RAID). Although these three products are provided in a single product package, they can be installed and used independently. For example (unless otherwise restricted by the platform itself), Intel® VMD is not required to enable and use Intel® VROC (SATA RAID). Likewise, Intel® VROC (VMD NVMe* RAID) can be enabled and used without Intel® VROC (SATA RAID).
The Intel® VROC software installer will automatically detect the hardware (CPU/chipset) present on a system and enable the applicable sub-products.
Intel® VROC Family Notes |
|
Intel® VROC provides RAID management through the BIOS that will allow for creation of RAID volumes using SATA or NVMe* drives as the vendor equipment allows. Configuration for each will be specified more directly within the documentation provided by the system vendor. The Intel® VROC Command-Line Interface (CLI) tools, as well as the Intel® VROC Graphical User Interface (GUI) for Windows*, enable the management of RAID volumes on NVMe* SSDs attached to PCI Express slots managed by the Intel® VMD controller via Intel® VROC (VMD NVMe* RAID) on Intel® VMD supported platforms, as well as RAID management provided for SATA drives connected to the Intel® PCH in RAID mode via Intel® VROC (SATA RAID).
Support on Intel® X299 HEDT Platforms | Intel® VROC (VMD NVMe* RAID) support on Intel® X299 High-End Desktop (HEDT) platforms is restricted to Intel NVMe* SSDs only. This is a platform limitation. As a result, when Intel® VROC is installed onto an Intel® X299 HEDT platform, the user will only see Intel NVMe* SSDs plugged into the platform. Using Intel® VROC on Intel® X299 HEDT platforms is not recommended. See details in Announcement: Intel® Virtual RAID on CPU (Intel® VROC) Support on X299 Platforms. |
As processing power continues to scale, high-bandwidth access to low-latency storage is critical to realizing the true potential of the CPU. Intel® VMD and Intel® VROC are features of Intel® Xeon® processors that enable a seamless transition to fast NVMe* storage to maximize CPU access to data, without a disruption in storage functionality.

Intel® VROC is an integrated RAID solution that scales with NVMe* SSDs to deliver extraordinary performance, over 5.7M IOPS. Intel® VROC performance is consistently better than RAID HBA, delivering up to 66% more IOPS, up to 40% lower latency and up to 62% better power efficiency.
Intel® VROC supports several SSDs and system configurations. See more details in the Intel® Virtual RAID on CPU (Intel® VROC) Supported Configurations.

What you should know about the Intel® VROC package | System vendors may customize the Intel® VROC package for their specific platforms. Reference your OEM for a full list of available feature sets. If any of the information in these resources conflict with the support information provided by the platform OEM, the platform documentation and configurations take precedence. Customers should always contact the place of purchase or the system/software manufacturer with support questions about their specific hardware or software configuration.
