Supported Intel® Virtual RAID on CPU (Intel® VROC) NVMe* Features on the Intel® D50TNP Module Family

The Intel® D50TNP Module family supports the following Intel® VROC (VMD NVMe* RAID) features:

• I/O processor with controller (ROC) and DDR4.
• Protected write-back cache.
• Isolated storage devices from operating system for error handling.
• Protected R5 data from operating system crash.
• NVMe* SSD hot plug and surprise removal on CPU PCIe* lanes.
• LED management for PCIe* attached storage.
• 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 and RAID 1 on all Intel® D50TNP Modules, plus RAID 5 and RAID 10 on Intel® D50TNP Storage Modules only.

• 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® D50TNP Modules as shown below:
