Ddv4 and Ddsv4-series

The Ddv4 and Ddsv4-series runs on the 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. These new VM sizes will have 50% larger local storage, as well as better local disk IOPS for both read and write compared to the Dv3/Dsv3 sizes with Gen2 VMs.

D-series use cases include enterprise-grade applications, relational databases, in-memory caching, and analytics.

Ddv4-series

Ddv4-series sizes run on the Intel® Xeon® Platinum 8272CL (Cascade Lake). The Ddv4-series offer a combination of vCPU, memory and temporary disk for most production workloads.

The new Ddv4 VM sizes include fast, larger local SSD storage (up to 2,400 GiB) and are designed for applications that benefit from low latency, high-speed local storage, such as applications that require fast reads/ writes to temp storage or that need temp storage for caches or temporary files. You can attach Standard SSDs and Standard HDDs storage to the Ddv4 VMs. Remote Data disk storage is billed separately from virtual machines.

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.

  • If you want to get the best performance for your VMs, you should limit the number of data disks to two disks per vCPU.

  • 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).
