Ddsv6-series virtual machines run on the 5th Generation Intel® Xeon® Platinum 8573C (Emerald Rapids) processor reaching an all-core turbo clock speed of 3.0 GHz. This new processor features Intel® Turbo Boost Technology, Intel® Advanced-Vector Extensions 512 (Intel® AVX-512), and Intel® Advanced Matrix Extensions. These virtual machines offer up to 192 vCPU and 768 GiB of RAM. Ddsv6-series virtual machines provide better performance for most general-purpose workloads compared to the prior generation with increased scalability, upgraded CPU performance, elevated memory bandwidth, faster NVMe local and remote storage access, and larger local storage capacity.
Ddsv6-series virtual machines offer local storage disks. You can attach Standard SSDs, Standard HDDs, Premium SSDs, and Premium SSD v2 storage to these virtual machines. You can also attach Ultra Disk storage based on its regional availability. Disk storage is billed separately from virtual machines.

Storage resources
Table definitions
- Total local temporary storage is calculated by multiplying the max number of storage disks with the temp disk size. For example, for the Standard_D192ds_v6, the total local temporary storage capacity is
6 x 1,760 GiB = 10,560 GiB.
- Temp disk performance depends on many factors including block size, workload patterns of read/writes, queue depth (QD), and others. Temp disk performance specifications should be viewed as best case performance numbers, assuming 4k block sizes and QD=256 for IOPS, and 256k block sizes with QD=64 for throughput. Read performance specs assume 100% reads, and write performance specs assume 100% writes. Additionally, write performance is heavily impacted by how many blocks in use on a device. Temp disk write performance specs assume a device has a clean slate to enable the best performance. During steady state operations, write performance is expected to be lower than the published specs.
- NVMe temp disks are presented as raw NVMe devices that need to be initialized and formatted before use. For more details on how to format and initialize drives, refer to the NVMe Temp Disk FAQ.
- The IOPS and throughput values shown are the combined performance across all temp disks.
- 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.
- To learn how to get the best storage performance for your VMs, see Virtual machine and disk performance.

- 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.

- 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).
