The FXmdsv2-series Virtual Machine (VM) runs on the 5th Generation Intel® Xeon® Platinum 8573C (Emerald Rapids) processor in a hyper threaded configuration. FXv2-series VMs features an all-core-turbo frequency up to 4.0 GHz. These virtual machines offer up to 96 vCPU, up to 1832 GiB of RAM and up to 6x880 GiB fast local SSD storage. The FXmdsv2-series benefits workloads that are ideal for memory-intensive enterprise applications requiring a high memory to CPU ratio, high performance, high CPU clock speed, higher remote storage IOPs and throughput. Typical use-cases for FX-series are the Electronic Design Automation (EDA) and SQL workloads.
FXmdsv2-series virtual machines support local storage. You can attach Standard SSDs, Standard HDDs, Premium SSDs, and Premium SSD V2 disk 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.

- 1Temp disk speed often differs between RR (Random Read) and RW (Random Write) operations. RR operations are typically faster than RW operations. The RW speed is usually slower than the RR speed on series where only the RR speed value is listed.
- 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.
- To learn how to get the best storage performance for your VMs, see Virtual machine and disk performance.

1Some 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 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.

- 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).
Accelerator (GPUs, FPGAs, etc.) info for each size
Note
No accelerators are present in this series.
Note
FXmdsv2-series VMs provision the ephemeral storage in a RAW state, which must be manually formatted and configured before installing SQL Server, when using the ephemeral storage for the tempdb database as dictated by best practices.
The ephemeral storage resets to RAW when the VM is deallocated or resized, which impacts some automation by preventing SQL Server from starting. For more information, see How to format and initialize temp NVMe disks and the SQL Server support guidance.
