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.
The following white paper provides an analysis of RAID performance and describes:
- The mathematics behind RAID performance.
- The specific RAID implementations of Intel® Virtual RAID on CPU (Intel® VROC).
- How operating systems, storage devices, and other components impact performance output.
|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 documents conflict with the support information provided by the platform OEM, the platform documentation and configurations take precedence.
