Scalable RAID for CPU-Attached SSDs

Download the Product Brief

Intel® Virtual RAID on CPU (Intel® VROC) – an enterprise RAID solution for NVMe* SSDs directly attached to Intel® Xeon® Scalable processors.

Today’s data hungry business processes need access to data quicker than ever. Quicker access to data means faster decision making, better productivity, and quicker ROI on IT infrastructure. Therefore, Enterprise data storage solutions are migrating to higher bandwidth and lower latency NVMe*-based SSDs to address the performance bottlenecks of legacy SATA/SAS interfaces. With this transition, enterprises also require RAID data protection for NVMe* SSDs.

Intel® Virtual RAID on CPU (Intel® VROC), a new enterprise RAID solution specifically designed for NVMe* SSDs, provides expected reliability while unleashing the performance of NVMe* SSDs. This is enabled by a new feature in next-generation Intel® Xeon® Scalable processors called Intel® Volume Management Device (Intel® VMD), an integrated controller inside the CPU PCIe* root complex. Because the NVMe* SSDs are directly connected to the CPU, the full performance potential of reduced latency and increased bandwidth can be realized. Intel® VROC enables this benefit without the complexity, cost, and power consumption of traditional hardware RAID host bus adapter (HBA) cards placed between the drives and the CPU.

Over 2.5M Read IOPS in 4-Disk RAID 0 with Intel® Optane™ SSDs.1

Scalable RAID for Growth on Demand
A single Intel® Xeon® Scalable processor using Intel® VROC is capable of supporting up to 12 NVMe* SSDs directly attached to the CPU, and up to 6 RAID arrays.2 On dualsocket system configurations, that amount doubles. In addition, Intel® VROC supports both boot volumes and data volumes, enabling the flexibility to use one array for both system and data volumes, or separating the arrays respectively. Although a boot RAID array needs to be within a VMD controller, data RAID arrays can span across multiple Intel® VMD controllers, or even span across different processors on the same system. With a multitude of supported configurations, Intel® VROC allows NVMe* RAID solutions to start small, then scale simply and cost effectively.

Rich Management Tools for Easy Maintenance
Intel® VROC management tools support today’s modernized data center infrastructure. Intel® VROC allows data center administrators to create and delete RAID volumes in both pre-OS and OS environments. RAID settings can be configured with either a user interface or command line, plus the arrays can be managed locally or remotely through a web-based RESTful agent.

NVMe*-based SSD management has never been easier. With support for surprise hot-plug, there is no need to reboot the server to replace a failed drive. Using the status indicator LED, administrators can visually identify the RAID status (normal, initialization, degraded, or fail), as well as locate a particular drive in hundreds of SSDs. Automatic email notifications are triggered to alert administrators of events requiring attention.

Reliable RAID for Data Protection
For enterprises, it’s critical to protect data when power loss occurs unexpectedly. Intel® VROC takes that a step further. Data remains safe when RAID 5 is in a degraded state and power loss occurs at the same time. Most RAID solutions avoid this problem by requiring a backup power unit, which adds additional cost. Intel® VROC solves this double fault challenge using a patent-pending journaling, without the need of backup power unit.

Note: Intel® VROC RAID 5 double fault protection feature depends on state-of-the-art data center NVMeSSDs with power loss protection.

Unleash the Power of NVMeSSDs Today
Quicker access to data means a more efficient business and upgrading to NVMeSSDs is the first step to a faster storage solution. Unleash the full power of these NVMeSSDs with Intel® Virtual RAID on CPU (Intel® VROC), a complete RAID solution that enables the unprecedented speed of NVMe* SSDs while protecting data required by enterprise applications.
