Advanced Virtualization I/O Queuing Technologies: An Intel-Microsoft Perspective
Enhanced Queuing Technologies for Improved Network Performance in Virtualized Servers
With the increase in the adoption of server virtualization and consolidation in data centers, there has been a continuous evolution of virtualization technologies in server components to improve the overall performance of the system and achieve the Service Level Objectives (SLOs) as defined. To improve the I/O performance of these virtualized servers, Intel has developed a breakthrough technology, Virtual Machine Device Queues (VMDQ). VMDQ helps off load network I/O data processing from the hypervisor software to the network silicon. Microsoft has developed VMQ technology, available in Windows Server* 2008 R2 Hyper-V*. These two technologies work together to improve I/O throughput for faster, more efficient networking.
Bigger Burdens for Hypervisors
Deploying virtualized environments is a growing practice among IT departments in order to consolidate server workloads and reduce data center footprints. Today’s more powerful servers allow for greater virtual machine (VM) density per virtualized server than ever before, yet this consolidation does not necessarily mean more efficient network throughput in the virtual environment. In fact, it can have a significant impact on system and application performance as workloads increasingly depend on network I/O. A balance between system performance and networking capabilities is required to achieve optimal application services from consolidation.
In the Hyper-V environment today, the virtual switch in the Management OS filters data based on VLAN tags and MAC addresses, copies the data, and then routes the data to the respective VMs via the VM Bus. The overhead associated with the virtual switch and the data copies impact a system’s overall network I/O performance, including both CPU utilization and throughput.
The solution provided by Microsoft and Intel with their complementary queuing technologies, VMQ and VMDq, reduces this impact to improve system performance.
