Microsoft on Thursday announced some perks and prods for Skype for Business unified communications users, with the aim of moving them to the Microsoft Teams collaboration service instead. Meltdown primarily affects Intel-based machines, while Spectre affects machines with Intel-, AMD- and ARM-based processors. Deploy a simple Linux VM with Accelerated Networking This template allows you to deploy a simple Linux VM with Accelerated Networking using Ubuntu version 18.04-LTS with the latest patched version. It will enable speeds of up to 25Gbps per Virtual Machine. Well, D15v2 with Accelerated Networking enabled able to deliver higher network bandwidth, around 22.8Gbps. In this post I am going to show how we can create VM with AN and verify its actions. This high-performance path bypasses the host from the datapath, reducing latency, jitter, and CPU utilization, for use with the most demanding network workloads on supported VM types. As the Senior Manager of Cloud Solutions at 360 Visibility, Jason has combined his technical and business development backgrounds to expand cloud based services and the company’s infrastructure customer base. Ratings . Coincidentally, this Accelerated Networking capability is arriving just in time to alleviate some potential performance hits that may occur when operating system updates are applied that aim to address Meltdown and Spectre CPU problems. Throughput is unaffected by the following factors: 1. We've worked to optimize the CPU and disk I/O path and are not seeing noticeable performance impact after the fix has been applied. Here is the workaround to enable accelerated networking for existing Linux VM. General availability means it's deemed ready for production use. Enable/Disable Accelerated Networking on Azure VM's Microsoft Azure has the option to enable Accelerated Networking on VM's. Microsoft on Thursday issued a reminder to organizations to ensure that their systems are properly patched for a "Critical"-rated Windows Netlogon vulnerability before next month's "update Tuesday" patch distribution arrives. These Linux and Windows OS updates for Meltdown and Spectre will downgrade system performance, as Intel and other chipmakers have acknowledged. Accelerated Networking is a feature that significantly enhances the performance you get out of a virtual machine. On instances that support hyperthreading, accelerated networking is supported on VM instances with four or more vCPUs… The … This script can be used to enable/disable this feature on your Azure VM's. An early report estimated a 30 percent maximum slowdown possibility for the Meltdown mitigation, but performance is thought to depend on the type of workloads being run. A supported VM size without accelerated networking enabled can only have the feature enabled when it is stopped and deallocated. an "Accelerated Maintenance FAQ" article, Microsoft Warns IT Pros on Windows Netlogon Fix Coming Next Month, Microsoft Nudging Skype for Business Users to Teams, How To Improve Windows 10's Sound and Video Quality, Microsoft Offers More 'Solorigate' Advice Using Microsoft 365 Defender Tools, Microsoft FastTrack Support Extended to Microsoft 365 Defender Solutions, Digital Dialogue: Cloud Video Interop and The New Hybrid Workforce, Managing Insider Threat-as-a-Service with NIST's Contingency Plan, Beyond the Perimeter: Continuous Monitoring With NIST's Zero Trust Security Model, How to Secure Your Remote Workforce with a Microsoft-Powered Solution. The requested VM size is supported by the cluster, but the cluster may not currently have sufficient capacity. The status of Accelerated Networking can be verified under the Network interfaces section of the Compute and Network settings for the replicated virtual machine. Virtual Switch is an important hop in the whole traffic route. This feature can be enabled on VM creation or on an existing VM meeting criteria in the stopped state. Expected outbound throughput and the number of network interfaces supported by each VM size is detailed in Azure Windows and Linux VM sizes. We are also pleased to announce the General Availability (GA) of Accelerated Networking (AN) for Windows with an expanded Public Preview for Linux. Please update the docs content accordingly. Accelerated networking can only be enabled for a new NIC. Beware that if you use a dynamic Public IP address for the VM, the public IP address will change as the VM is redeployed. Best of all, it’s free! list-skus: The number of skus is less than latter … AzureRm.AcceleratedNIC.zip. Accelerated networking is supported on most general purpose and compute-optimized instance sizes with two or more virtual CPUs (vCPUs). Feedback? This feature can be enabled on VM creation or on an existing VM meeting criteria in the stopped state. Accelerated Networking is supported on most general purpose and compute-optimized instance sizes with 2 or more vCPUs. On Jan. 3, Microsoft released Windows security patches in advance of its "update Tuesday" schedule that are designed to mitigate the attack possibilities associated with Meltdown and Spectre, which are said to be capable of tapping the CPUs cache side channel to access OS kernel information. They can be used to surface password and encryption key information from Linux and Windows machines. Accelerated Networking is configured on the Network Interface object itself, which works in conjunction with selected VM sizes and Operating Systems within the Azure Platform. This feature cannot enable in existing VMs. Decreased CPU Utilization: Bypassing the virtual switch in the host leads to less CPU utilization for processing network traffic, leaving more capacity for processing large amounts of data being sent or received. Select a type, such as General purpose, then select a size-series on the resulting page, such as the Dv2-series. If you need to enable this feature after VM creation you will require to do so through powershell as it is not yet supported in the portal. The feature is free but is only available in selective VM sizes. Number of Data Disks Allowed I wanted to change one of my Development VMs to a DS12_v2, but that choice wasn't available: In Figure 1 we have two Virtual Machines deployed in the same Virtual Network. It is also available for most hyperthreading VMs with 4 or more vCPUs. Organizations have to start with a new VM and attach a new network interface card at the time of creation, according to Microsoft's Azure Windows documentation and Linux documentation.
