Mdsv3 Very High Memory Series
The Mdsv3 Very High Memory (VHM) series, powered by 4th generation Intel® Xeon® Platinum 8490H (Sapphire Rapids) processor with an all core base frequency of 1.9 GHz and 3.5 GHz single core turbo frequency, are the next generation of memory-optimized VM sizes delivering faster performance, lower total cost of ownership and improved resilience to failures compared to the previous generation. The Mv3 VHM sizes offer 32TB of memory, up to 8 GBps of throughput for remote storage, and provide up to 185 Gbps of networking performance with the current VHM generation.

1VHM VM Sizes are virtual machine sizes that are Isolated to a specific hardware type and dedicated to a single customer.
2The Standard_m896ixds_32_v3 VM comes without Simultaneous Multithreading (SMT), meaning a vCPU is mapped to a full physical core.
It's also important to note that these VMs are compatible with only certain generation 2 Images. For a list of images that are compatible with the Mdsv3-series, please see below
- Windows Server 2022 Datacenter Edition latest builds
- SUSE Linux enterprise Server 15 SP4 and later
- Red Hat Enterprise Linux 8.8 or later
- Ubuntu 23.10 or later
Important
Please contact your Azure Account Manager to inquire about accessing these VHM VM sizes.
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).
