However, it has been made available for a couple of Virtual Machine series and sizes where there is a real need for Network performance and those VMs are meant for high CPU utilization tasks. Reduced jitter: Virtual switch processing depends on the amount of policy that needs to be applied. Another option in the ethtool is look activity in the the virtual function using the command: ‘ethtool -S eth0 | grep vf_’. Another benefit of receive side scaling (RSS) is that all TCP connection is shared across multiple processor cores. We should see the Mellanox ConnectX being listed as depicted in the image below.

You may have noticed that I said should support, as you are aware, Microsoft Azure is dynamic and it is continuously changing. On devices with … Before we explore what Accelerated Networking is let us try to understand how Azure Virtual Machines communicate with each other in a virtual network. googletag.defineSlot('/40773523/TG-Sponsored-Text-Link', [848, 75], 'div-gpt-featured-links-tg-spon-2').addService(googletag.pubads()).setCollapseEmptyDiv(true); i.e. Use only every second interface in boxnet (e.g., eth0, eth2, eth4). When using the accelerated networking feature, the traffic goes straight from the VM to the physical NIC (network interface card). For Accelerated Networking in Azure, it just supports the size series D/DSv2 and F/Fs, D/DSv3, E/ESv3, Fsv2, and Ms/Mms. It will create a datapath directly from VM to the Mellanox network card on Azure hosting infrastructure. This feature cannot enable in existing VMs. There are a couple of quick verification steps you can perform this depends also the operating system you deployed of course. Azure CLI can be used as well to enable Accelerated Networking either during creation or afterwards. We’re still on the ‘beyond CPUs’ theme today, with a great paper from Microsoft detailing their use of FPGAs to accelerate networking in Azure. Step 1 - Select a Virtual Machine with a supporting Operating System. We can also check if any given network interface attached to a virtual machine to see if the accelerated network is enabled. The rule of thumb is that general-purpose and compute-optimized with two or move vCPUs should support the feature. If you want to automate this process on a VM basis, I wrote the following PowerShell script to perform the entire process. googletag.defineSlot('/40773523/TG-Sponsored-Text-Link', [848, 75], 'div-gpt-featured-links-tg-spon-5').addService(googletag.pubads()).setCollapseEmptyDiv(true); AN provides consistent ultra-low network latency via Azure's in-house programmable hardware and technologies such as SR-IOV.
