The Epdsv6-series virtual machines are powered by Azure’s first-generation Cobalt 100 processor, delivering outstanding performance for memory optimized workloads. The Azure Cobalt 100 processor operates at 3.4 GHz and provides an entire physical core for each virtual machine vCPU. These virtual machines offer 8 GiB of memory per vCPU and a wide range of vCPU sizes. These VMs are best suited for memory-intensive scale-out and enterprise workloads, such as relational database servers, large databases, data analytics engines, in-memory caches, and more. Epdsv6-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. For more information, see pricing for disks. Epdsv6-series virtual machines offer up to 96 vCPU, up to 672 GiB of RAM, and up to 5,280 GiB of fast local NVMe temporary storage.
The Epdsv6 VM series will only work on OS images that support NVMe (i.e. NVMe drivers required for the local storage). 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.
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 (R-O) or ReadWrite (R-W). For uncached data disk operation, the host cache mode is set to None.
1These sizes support bursting to temporarily increase disk performance. Burst speeds can be maintained for up to 30 minutes at a time.

Accelerated networking is required and turned on by default on all Epdsv6 machines.
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).
