Intel will continue to offer VMD and VROC on existing and future platforms. Please contact your OEM for support and SKU-specific information. Learn more here.

Intel® Virtual RAID on CPU (Intel® VROC)

Intel® VROC is an enterprise RAID solution that unleashes the performance of NVMe SSDs, 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. 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, Including:

  • High performance due to direct connect of SSDs
  • Platform integrated storage controller functions provided by Intel® VMD
  • Boot and Data RAID
  • Scalable to many devices and RAID arrays
  • Support for SATA and NVMe RAID arrays

英特尔® VROC 利用 Intel® 支持 VMD 的 PCIe 通道可直接管理 NVMe SSD。给定 CPU 上 VMD 域的数量是 PCIe 通道数量的函数。每 16 个 PCIe 通道，有一个 Intel® VMD 域可用。

  • 48个 PCIe 通道 = 3个 Intel® VMD 域
  • 64个 PCIe 通道 = 4个 Intel® VMD 域
