Msv2 Medium Memory sizes series

The Msv2 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.

Storage resources

Attaching Ultra Disk or Premium SSD v2 disks to Standard_M192is_v2 results in higher IOPs and MBps than standard premium disks:
- Max uncached Ultra Disk and Premium SSD v2 throughput (IOPS/ MBps): 120000/2000
- Max burst uncached Ultra Disk and Premium SSD v2 throughput (IOPS/ MBps): 120000/4000

¹Some sizes support bursting to temporarily increase disk performance. Burst speeds can be maintained for up to 30 minutes at a time.
²Special Storage refers to either Ultra Disk or Premium SSD v2 storage.
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.

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).
