Supported Intel® Virtual RAID on CPU (Intel® VROC) for NVMe* Features on Intel® Compute Module D40AMP


Install & Setup



The Intel® Compute Module D40AMP supports the following Intel® Virtual RAID on CPU (Intel® VROC) features:

  • Bootable RAID
  • Self-encrypting drive (SED) key management in UEFI
  • Integrated caching with Intel® Optane™ SSDs
  • RAID 5 power loss protection for degraded volumes (double fault protection)
  • Isolated storage devices from operating system for error handling
  • NVMe* SSD hot plug and surprise removal on CPU PCIe* lanes
  • LED management for PCIe* attached storage
  • Hot-spare and auto-rebuild
  • Bad block management
  • Email notification for RAID events
  • Configurable strip sizes (4k, 8k, 16k, 32k, 64k, and 128k)
  • RAID/storage management using representational state transfer (RESTful) application programming interfaces (APIs)
  • Graphical user interface (GUI) for Windows* and Linux*
  • 4K native NVMe* SSD support

Intel® VROC (VMD NVMe* RAID) offers several options for RAID to meet the needs of the end user. Supported RAID levels include:

  • RAID 0: Uses striping to provide high data throughput, especially for large files in an environment that does not require fault tolerance.
  • RAID 1: Uses mirroring so that data written to one disk drive simultaneously writes to another disk drive. This is good for small databases or other applications that require small capacity but complete data redundancy.
  • RAID 5: Uses disk striping and parity data across all drives (distributed parity) to provide high data throughput, especially for small random access. A minimum of three drives is required.
  • RAID 10: A combination of RAID 0 and RAID 1 on four drives, it consists of striped data across mirrored spans. It provides high data throughput and complete data redundancy, but it uses a larger number of spans.

Enabling Intel® VROC (VMD NVMe* RAID) support requires the installation of an optional upgrade key (iPC – VROCSTANMOD or iPC – VROCPREMMOD) in the Intel® Compute Modules D40AMP as shown below:
