Dasv6-series sizes

Dasv6-series VMs utilize AMD's 4th Generation EPYC™ 9004 processors that can achieve a boosted maximum frequency of 3.7GHz. These virtual machines offer up to 96 vCPU and 384 GiB of RAM. The Dasv6-series sizes offer a combination of vCPU and memory for most production workloads. The new VMs with no local disk provide a better value proposition for workloads that do not require local temporary storage.

Storage resources

Table definitions

Some sizes support bursting to temporarily increase disk performance. Burst speeds can be maintained for up to 30 minutes at a time.
Storage capacity is shown in units of GiB or 1,024^3 bytes. When you compare disks measured in GB (1,000^3 bytes) to disks measured in GiB (1,024^3) remember that capacity numbers given in GiB may appear smaller. For example, 1,023 GiB = 1,098.4 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.

Networking resources

Table definitions

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).

Note

This VM series will only work on OS images that support NVMe. If your current OS image doesn't have NVMe support, you'll see an error message. NVMe support is available on the most popular OS images, and we're continuously improving OS image compatibility. Some Azure services might refer to this VM series as Dav6 rather than Dasv6. This is a known naming inconsistency and doesn't affect VM capabilities, including Premium Storage support.
