For frequently asked questions, refer to Azure VM sizes with no local temp disk.

Ev4-series

Ev4-series sizes run on Intel® Xeon® Platinum 8473C (Sapphire Rapids), Intel® Xeon® Platinum 8370C (Ice Lake), or Intel® Xeon® Platinum 8272CL (Cascade Lake). The Ev4-series instances are ideal for memory-intensive enterprise applications. Ev4-series VMs feature Intel® Hyper-Threading Technology.

Remote Data disk storage is billed separately from virtual machines. To use premium storage disks, use the Esv4 sizes. The pricing and billing meters for Esv4 sizes are the same as Ev4-series.

1 Esv4-series VMs can burst their disk performance and get up to their bursting max for up to 30 minutes at a time.

2 Constrained core sizes available).

3 Instance is isolated to hardware dedicated to a single customer.

4 Accelerated networking can only be applied to a single NIC.

5 Attaching Ultra Disk or Premium SSDs V2 to Standard_E80is_v4 results in higher IOPs and MBps than standard premium disks:

  • Max uncached Ultra Disk and Premium SSD V2throughput (IOPS/ MBps): 120000/1800
  • Max burst uncached Ultra Disk and Premium SSD V2 disk throughput (IOPS/ MBps): 120000/2000

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).
