The 'M' family of VM size series are one of Azure's ultra memory-optimized VM instances designed for extremely memory-intensive workloads, such as large in-memory databases, data warehousing, and high-performance computing (HPC). Equipped with substantial RAM capacities and high vCPU capabilities, the M-family VMs support applications and services that require massive amounts of memory and significant computational power. High resource allocation makes the M-family particularly well-suited for handling tasks such as heavy SQL Server and other RDBMS workloads, complex scientific simulations, real-time data processing, and large-scale enterprise resource planning (ERP) systems, ensuring peak performance for the most demanding data-centric applications.
Workloads and use cases
SQL Server workloads with high memory needs: The M-family is particularly effective for running SQL Server machines with high memory requirements, such as for online transaction processing (OLTP) or data analytics.
In-memory databases: The M-family is particularly effective for running in-memory databases that require large amounts of RAM like SQL Server, or SAP HANA.
Big data applications: The M-family is ideal for handling big data applications that need to process and analyze huge datasets in memory, improving performance and reducing the time to insights.
Data warehousing: M-family VMs provide the performance and memory needed for data warehousing applications, facilitating faster queries and better handling of large volumes of data.
Enterprise applications: The M-family supports large-scale enterprise applications, including ERP and CRM systems, which benefit from having more memory to manage larger datasets and more complex transactions efficiently.
Heavy workloads in virtualized environments: The M-family is well-equipped to handle heavy virtualized environments, offering substantial memory for hosting multiple virtual machines and applications on a single physical server.
Series in family
Msv2 and Mdsv2 Medium Memory 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.
