Dv4 and Dsv4-series

  • Article

Applies to: ✔️ Linux VMs ✔️ Windows VMs ✔️ Flexible scale sets ✔️ Uniform scale sets

The Dv4 and Dsv4-series run on Intel® Xeon® Platinum 8473C (Sapphire Rapids), Intel® Xeon® Platinum 8370C (Ice Lake), or Intel® Xeon® Platinum 8272CL (Cascade Lake) processors in a hyper-threaded configuration, providing a better value proposition for most general-purpose workloads. It features an all core Turbo clock speed of 3.4 GHz, Intel® Turbo Boost Technology 2.0, Intel® Hyper-Threading Technology and Intel® Advanced Vector Extensions 512 (Intel® AVX-512). They also support Intel® Deep Learning Boost.

Dv4-series

Dv4-series sizes run on Intel® Xeon® Platinum 8473C (Sapphire Rapids), Intel® Xeon® Platinum 8370C (Ice Lake), or Intel® Xeon® Platinum 8272CL (Cascade Lake). The Dv4-series sizes offer a combination of vCPU, memory and remote storage options for most production workloads. Dv4-series VMs feature Intel® Hyper-Threading Technology.

Remote Data disk storage is billed separately from virtual machines. To use premium storage disks, use the Dsv4 sizes. The pricing and billing meters for Dsv4 sizes are the same as Dv4-series.

Note

After a restart, a file named Data_loss_warning.txt might be appear beside drive C (the first data disk attached from the Azure portal). In this scenario, despite the file name, no data loss has occurred on the disk. In general, the Data_loss_warning.txt file usually is copied on the temporary drive. If you're using a VM that doesn't have a temp drive, WindowsAzureGuestAgent incorrectly copies the file to the first drive letter. In v4 VMs, the first drive letter is a data disk.

A resolution for this issue was applied in the latest version (version 2.7.41491.999) of the VM agent.

Size table definitions

  • Storage capacity is shown in units of GiB or 1024^3 bytes. When you compare disks measured in GB (1000^3 bytes) to disks measured in GiB (1024^3) remember that capacity numbers given in GiB may appear smaller. For example, 1023 GiB = 1098.4 GB.

  • Disk throughput is measured in input/output operations per second (IOPS) and MBps where MBps = 10^6 bytes/sec.

  • Data disks can operate in cached or uncached modes. For cached data disk operation, the host cache mode is set to ReadOnly or ReadWrite. For uncached data disk operation, the host cache mode is set to None.

  • To learn how to get the best storage performance for your VMs, see Virtual machine and disk performance.

  • Expected network bandwidth is the maximum aggregated bandwidth allocated per VM type across all NICs, for all destinations. For more information, see Virtual machine network bandwidth.

    Upper limits aren't guaranteed. Limits offer guidance for selecting the right VM type for the intended application. Actual network performance will depend on several factors including network congestion, application loads, and network settings. For information on optimizing network throughput, see Optimize network throughput for Azure virtual machines. To achieve the expected network performance on Linux or Windows, you may need to select a specific version or optimize your VM. For more information, see Bandwidth/Throughput testing (NTTTCP).
