Memory optimized Linux VM sizes

  • The M-Series offers the highest vCPU count (up to 128 vCPUs) and largest memory (up to 2.0 TiB) of any VM in the cloud. It’s ideal for extremely large databases or other applications that benefit from high vCPU counts and large amounts of memory.

  • Dv2-series, D-series, G-series, and the DS/GS counterparts are ideal for applications that demand faster vCPUs, better temporary storage performance, or have higher memory demands. They offer a powerful combination for many enterprise-grade applications.

  • D-series VMs are designed to run applications that demand higher compute power and temporary disk performance. D-series VMs provide faster processors, a higher memory-to-vCPU ratio, and a solid-state drive (SSD) for temporary storage. For details, see the announcement on the Azure blog, New D-Series Virtual Machine Sizes.

  • Dv2-series, a follow-on to the original D-series, features a more powerful CPU. The Dv2-series CPU is about 35% faster than the D-series CPU. It is based on the latest generation 2.4 GHz Intel Xeon® E5-2673 v3 (Haswell) processor, and with the Intel Turbo Boost Technology 2.0, can go up to 3.1 GHz. The Dv2-series has the same memory and disk configurations as the D-series.

ESv3-series

ACU: 160-190

ESv3-series instances are based on the 2.3 GHz Intel XEON ® E5-2673 v4 (Broadwell) processor and can achieve 3.5GHz with Intel Turbo Boost Technology 2.0 and use premium storage. Ev3-series instances are ideal for memory-intensive enterprise applications.

Size table definitions

  • Storage capacity is shown in units of GiB or 1024^3 bytes. When comparing 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 performance is the maximum aggregated bandwidth allocated per VM type across all NICs, for all destinations. Upper limits are not guaranteed, but are intended to provide guidance for selecting the right VM type for the intended application. Actual network performance will depend on a variety of factors including network congestion, application loads, and network settings. For information on optimizing network throughput, see Optimizing network throughput for Windows and Linux. To achieve the expected network performance on Linux or Windows, it may be necessary to select a specific version or optimize your VM. For more information, see How to reliably test for virtual machine throughput.

  • † 16 vCPU performance will consistently reach the upper limit in an upcoming release.
