Breakthrough Technology: Virtual Machine Device Queues (VMDq)

Intelligent Queueing Technologies for Virtualization: An Intel-VMware Perspective: Enhanced Network Performance in Virtualized Servers

Introduction

As server virtualization continues to grow in IT departments—from small businesses to enterprises—virtualization technologies continue to evolve, improving system throughput for virtual machines and enhancing performance in virtual environments. Virtual Machine Device Queues (VMDq) is another breakthrough technology from Intel that helps offload network I/O data processing from the hypervisor software to the network silicon. When combined with VMware’s network multi-queue technology (NetQueue*), VMDq improves I/O throughput for faster, more efficient networking.

Bigger Burdens for Hypervisors

Deploying virtualized environments on more powerful platforms is a growing practice among IT departments in order to consolidate server workloads and reduce data center footprints. However, this practice can have a significant impact on system and application performance as workloads increasingly depend on network I/O. While IT managers are adding greater processing power and reducing the infrastructure footprint, this kind of consolidation does not necessarily mean more efficient network throughput in the virtual environment. A balance between system performance and networking capabilities is required to achieve optimal application services from consolidation.

In virtual environments today, the hypervisor manages network I/O activities. With more virtual machines (VMs) and increased traffic through the platform, the hypervisor requires more CPU cycles to sort data packets and route them to the correct VM, reducing CPU capacity available for applications. Intel’s VMDq is a breakthrough technology that reduces the burden on the hypervisor while improving network I/O performance through the virtualized platform.
