Virtual Machine Device Queues
An Integral Part of Intel® Virtualization Technology for Connectivity that Delivers Enhanced Network Performance
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 virtual machine monitor software to the network silicon.
Summary
More processing power provides opportunity for greater consolidation in IT data centers; however, the impact to I/O cannot be forgotten. Virtual Machine Device Queues offload the data packet sorting overhead from the hypervisor switch to hardware in the network silicon. Data packet sorting in the network silicon, plus individual queues for each VM, free more CPU cycles for application processing instead of network I/O processing. In a benchmark study, the addition of VMDq to Intel network silicon more than doubled the throughput on a virtualized platform.
