Msv2 and Mdsv2-series Medium Memory
Applies to: ✔️ Linux VMs ✔️ Windows VMs ✔️ Flexible scale sets ✔️ Uniform scale sets
The Msv2 and Mdsv2 Medium Memory VM Series features Intel® Xeon® Platinum 8280 (Cascade Lake) processor with an all core base frequency of 2.7 GHz and 4.0 GHz single core turbo frequency. With these VMs, customers achieve increased flexibility with local disk and diskless options. Customers also have access to a set of new isolated VM sizes with more CPU and memory that go up to 192 vCPU with 4 TiB of memory.
Msv2 and Mdsv2 Medium Memory VMs are generation 2 only. For more information on generation 2 virtual machines, see Support for generation 2 VMs on Azure.

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).
