Intel® Virtual RAID on CPU (Intel® VROC)
Intel® VROC is an enterprise RAID solution that unleashes the performance of NVMe SSDs, enabled by a feature in Intel® Xeon® Scalable processors called Intel® Volume Management Device (Intel® VMD), an integrated controller inside the CPU PCIe root complex. Intel® VROC enables these benefits without the complexity, cost, and power consumption of traditional hardware RAID host bus adapter (HBA) cards placed between the drives and the CPU.
Intel® VROC Is a Complete RAID Solution, Including:
- High performance due to direct connect of SSDs
- Platform integrated storage controller functions provided by Intel® VMD
- Boot and Data RAID
- Scalable to many devices and RAID arrays
- Support for SATA and NVMe RAID arrays
Powered by Intel® Xeon® Processors
As processing power continues to scale, high-bandwidth access to low-latency storage is critical to realizing the true potential of the CPU. Intel® VMD and Intel® VROC are features of Intel® Xeon® processors that enable a seamless transition to fast NVMe storage to maximize CPU access to data, without a disruption in storage functionality.
Performance Highlights
Intel® VROC is an integrated RAID solution that scales with NVMe SSDs to deliver extraordinary performance, over 5.7M IOPS. Intel® VROC performance is consistently better than RAID HBA, delivering up to 66% more IOPS, up to 40% lower latency and up to 62% better power efficiency.1

Features

Isolate Error Handling
Intel® VMD isolates SSD error and event handling from the operating system to help reduce system crashes and reboots.

Enterprise Reliability
Increased protection from data loss and corruption in various failure scenarios such as unexpected power loss, even when a volume is degraded.

Extended Management Tools
Pre-OS and OS management includes HII, CLI, email alerts, and a Windows GUI, all supporting NVMe and SATA controls.

Boot RAID
Redundancy for OS images directly off the CPU with pre-OS configuration options for platform set-up.

High Performance Storage
Connect NVMe SSDs directly to the CPU for full bandwidth storage connections.

Out Of Band Management
Retrieve drive inventory, monitor drive/RAID volume state and trigger RAID create/delete and LED management

SED Key Management
Secure sensitive data volumes with Self Encrypting Drives and boot from a RAID volume or a single drive
