If your Windows VM supports Accelerated Networking, enabling that feature would be the optimal configuration for throughput. 1. To get the latest optimizations, first install the latest supported version of 18.04-LTS, as follows: After the creation is complete, enter the following commands to get the latest updates. For all other Windows VMs, using Receive Side Scaling (RSS) can reach higher maximal throughput than a VM without RSS. Azure virtual machines are priced per second, and can be used in one of two ways: either on a pay as you go basis, or on a reserved basis. A network virtual appliance (NVA) is a virtual appliance primarily focused on network functions virtualization. Intel® AVX-512 instructions are new on Intel Scalable Processors. Compute optimized Azure VM types offer a high CPU-to-memory ratio. Leverage free manageability to simplify SQL Server administration and Performance Optimized Storage configuration to boost SQL Server performance on Azure VMs by creating a new SQL VM through Azure Portal or registering with SQL VM RP today. Part one covered the basics of creating a VM, and setting up networking, backup and monitoring before deploying VMs. The throughput optimization is in LIS, starting from 4.2.2-2, although later versions contain further improvements. To gain max performance, run eight jobs per device to match. Released on Friday, the technology is available for use with both Linux- … The Fsv2-series runs on 2nd Generation Intel® Xeon® Platinum 8272CL (Cascade Lake) processors and Intel® Xeon® Platinum 8168 (Skylake) processors. Azure’s GPU optimized VMs are designed for specialized workloads which run NVIDIA’s graphical processing units (GPUs). With the same test repeated with SQL server data and log files on Ultra Disk, we got up to 1,489 TPS and utilized all VM resources at peak (the CPU is consumed at 92%). Azure virtual machines (VM) have default network settings that can be further optimized for network throughput. Summary: Note that the Virtual Network stack isn't inherently inefficient because it fragments packets at 1,400 bytes even though VMs have an MTU of 1,500. If your Windows VM supports Accelerated Networking, enabling that feature would be the optimal configuration for throughput. Fsv2-series Lower Latency / Higher packets per second (pps): Removing the virtual switch from the datapath removes the time packets spend in the host for policy processing and increases the number of packets that can be processed inside the VM. 2. These steps also work for VMs currently running the Ubuntu Azure kernel. The default MTU for Azure VMs is 1,500 bytes. A Reconnecting dialog box appears during the connectivity loss. VM availability is critical to our customers’ success on the azure platform, and machine learning and live migration are pivotal to Azure’s commitment to this customer promise. Azure ultra-disks deliver high throughput, high IOPS, and consistent low latency disk storage for Azure VMs. RSS may be disabled by default in a Windows VM. Performance-optimized storage configuration capabilities for virtual machines (VMs) registered with SQL VM Resource Provider are now available. In the following example output returned from the Get-NetAdapterRss, RSS is not enabled. For all other Windows VMs, using Receive Side Scaling (RSS) can reach higher maximal throughput than a VM … VM Bandwidth. Microsoft's Accelerated Networking technology for Azure virtual machines (VMs) is now production-ready. A typical network virtual appliance involves various layers four to seven functions like firewall, WAN optimizer, application delivery controllers, routers, load balancers, IDS/IPS, proxies, SD-WAN edge, and more. Azure virtual machine sizes naming conventions. The command changed NIC settings, causing temporary connectivity loss for about one minute. Connectivity is typically restored after the third attempt. Windows VM. Confirm that RSS is enabled in the VM by entering the Get-NetAdapterRss command again. Reduced jitter: Virtual switch processing depends on the amount of policy that needs to be applied and the workload of the CPU that is doing the processing. Significant throughput performance can be achieved by upgrading to the Azure Linux kernel. In tunnel mode traffic to be optimized needs to be routed to the Wanos VM. Linux kernels released since October 2017 include new network optimisations options that enable a Linux VM to achieve higher network throughput. There are a few catches to using Accelerated Networking, though. It features Intel® Deep Learning Boost Technology, Intel® Advanced Vector Extensions 512 […] In other words, they're really fast for any computational workload. The S in a VM name means the VM can use Premium Storage (SSD based), an R stands for RDMA networking and an M stands for memory optimized, for instance the Standard_H8m has eight vCPUs but the m indicates that the memory multiplier is higher (14x) for 112GB of memory, max data disks of 32 (4x) and max vNICs of four (0.5x). Misconfigured virtual machines cause security vulnerabilities and availability issues, although users familiar with Azure can leverage the platform’s tools to optimize both. Optimizing Azure costs begins with knowing your current Azure expenditures. This is the third and final part in a series where I look at Infrastructure-as-a-Service (IaaS) virtual machines (VMs) in Microsoft Azure.
