DCsv3 and DCdsv3-series

  • Article

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

The DCsv3 and DCdsv3-series Azure Virtual Machines help protect the confidentiality and integrity of your code and data while they're being processed in the public cloud. By using Intel® Software Guard Extensions and Intel® Total Memory Encryption - Multi Key, customers can ensure their data is always encrypted and protected in use.

These machines are powered by the latest 3rd Generation Intel® Xeon Scalable processors, and use Intel® Turbo Boost Max Technology 3.0 to reach 3.5 GHz.

With this generation, CPU Cores have increased 6x (up to a maximum of 48 physical cores). Encrypted Memory (EPC) has increased 1500x to 256 GB. Regular Memory has increased 12x to 384 GB. All these changes substantially improve the performance and unlock entirely new scenarios.

Note

Hyperthreading is disabled for added security posture. Pricing is the same as Dv5 and Dsv5-series per physical core.

There are two variants for each series, depending on whether the workload benefits from a local disk or not. You can attach remote persistent disk storage to all VMs, whether or not the VM has a local disk. As always, remote disk options (such as for the VM boot disk) are billed separately from the VMs in any case.

DCsv3-series instances run on a 3rd Generation Intel® Xeon Scalable Processor 8370C. The base All-Core frequency is 2.8 GHz. Turbo Boost Max 3.0 is enabled with a max frequency of 3.5 GHz.

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).
