6.6 Intel Virtual RAID on CPU (VROC)

Intel Virtual RAID on CPU (Intel VROC) is an enterprise RAID solution for NVMe SSDs
®
directly attached to Intel Xeon Scalable processors. Intel Volume Management Device (VMD)
is an integrated controller inside the CPU PCIe root complex.
•
A single processor supports up to 12 NVMe SSDs and up to 6 RAID arrays.
•
A dual processor system supports up to 24 NVMe SSDs and 12 RAID arrays.
Strip sizes are 4K, 8K, 16K, 32K, 64K, 128K.

Requirements and Restrictions

•
Intel VROC is only available when the system is configured for UEFI boot mode.

•
To enable Intel VROC, a hardware key must be inserted on the motherboard, and the
appropriate processor's Virtual Management Devices must be enabled in the BIOS setup.
•
It is possible to enable Intel VROC without a hardware key installed, but only RAID0 will
be enabled.
•
Intel VROC is not compatible with secure boot. This feature must be disabled.
•
When creating bootable OS RAID1 devices, you must have both devices on the same
CPU, and a VMD on that CPU.
•
Spanning drives when creating RAID devices is not recommended to due to performance
issues, even though it is supported.
