Dalsv6 and Daldsv6-series (Preview)

  • Article

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

Important

Azure Virtual Machine Series Dalsv6 and Daldsv6 are currently in PREVIEW. See the Supplemental Terms of Use for Microsoft Azure Previews for legal terms that apply to Azure features that are in beta, preview, or otherwise not yet released into general availability. 

The Dalsv6-series and Daldsv6-series utilize AMD's 4th Generation EPYCTM 9004 processor in a multi-threaded configuration with up to 320 MB L3 cache. The Dalsv6 and Daldsv6 VM series provides 2GiBs of RAM per vCPU and are optimized for workloads that require less RAM per vCPU than standard VM sizes. The Dalsv6-series can reduce costs when running non-memory intensive applications, including web servers, gaming, video encoding, AI/ML, and batch processing. 

Note

The new Dalsv6 and Daldsv6 VM series will only work on OS images that are tagged with NVMe support.  If your current OS image is not supported for NVMe, you’ll see an error message. NVMe support is available in 50+ of the most popular OS images, and we continuously improve the OS image coverage. Please refer to our up-to-date lists for information on which OS images are tagged as NVMe supported.  For more information on NVMe enablement, see our FAQ.

The new Dalsv6 and Daldsv6 VM series virtual machines public preview now available. For more information and to sign up for the preview, please visit our announcement and follow the link to the sign-up form. This is an opportunity to experience our latest innovation.

Dalsv6-series

Dalsv6-series VMs utilize AMD's 4th Generation EPYCTM 9004 processors that can achieve a boosted maximum frequency of 3.7GHz. These virtual machines offer up to 96 vCPU and 192 GiB of RAM. These VM sizes can reduce cost when running non-memory intensive applications. The new VMs with no local disk provide a better value proposition for workloads that do not require local temporary storage. 

Note

For frequently asked questions, see Azure VM sizes with no local temp disk.

Dalsv6-series virtual machines do not have any temporary storage thus lowering the price of entry. You can attach Standard SSD, Standard HDD, and Premium SSD disk types. You can also attach Ultra Disk storage based on its regional availability. Disk storage is billed separately from virtual machines. See pricing for disks.

Daldsv6-series

Daldsv6-series VMs utilize AMD's 4th Generation EPYCTM  9004 processors that can achieve a boosted maximum frequency of 3.7GHz. These virtual machines offer up to 96 vCPUs, 192 GiB of RAM, and up to 5,280 GiB of fast local NVMe temporary storage. These VM sizes can reduce cost when running non-memory intensive applications.  Daldsv6-series virtual machines support Standard SSD, Standard HDD, and Premium SSD disk types. You can also attach Ultra Disk storage based on its regional availability. Disk storage is billed separately from virtual machines. See pricing for disks.

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).
