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) is a new enterprise RAID solution specifically designed for NVMe SSDs that provides expected reliability, while unleashing the performance of NVMe SSDs. This is made possible 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 HBA cards placed between the drives and the CPU.
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 dual- socket 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 using either a user interface or command line, plus the arrays can be managed locally or remotely through a web-based RESTful agent. |
