Ebdsv5 and Ebsv5 series

Applies to: ✔️ Linux VMs ✔️ Windows VMs ✔️ Flexible scale sets ✔️ Uniform scale sets

The memory-optimized Ebsv5 and Ebdsv5 Azure virtual machine (VM) series deliver higher remote storage performance in each VM size than the Ev4 series. The increased remote storage performance of the Ebsv5 and Ebdsv5 VMs is ideal for storage throughput-intensive workloads. For example, relational databases and data analytics applications.

The Ebsv5 and Ebdsv5 VMs offer up to 120000 IOPS and 4000 MBps of remote disk storage throughput. Both series also include up to 512 GiB of RAM. The Ebdsv5 series has local SSD storage up to 2400 GiB. Both series provide a 3X increase in remote storage performance of data-intensive workloads compared to prior VM generations. You can use these series to consolidate existing workloads on fewer VMs or smaller VM sizes while achieving potential cost savings. The Ebdsv5 series comes with a local disk and Ebsv5 is without a local disk. Standard SSDs and Standard HDD disk storage aren't supported in the Ebv5 series.

The Ebdsv5 and Ebsv5 series run on the Intel® Xeon® Platinum 8370C (Ice Lake) processors in a hyper-threaded configuration. The series are ideal for various memory-intensive enterprise applications. They feature:

Ebdsv5 series

Ebdsv5-series sizes run on the Intel® Xeon® Platinum 8370C (Ice Lake) processors. The Ebdsv5 VM sizes feature up to 512 GiB of RAM, in addition to fast and large local SSD storage (up to 2400 GiB). These VMs are ideal for memory-intensive enterprise applications and applications that benefit from high remote storage performance, low latency, high-speed local storage. Remote Data disk storage is billed separately from VMs.

Note

Accelerated networking is required and turned on by default on all Ebdsv5 VMs.

Accelerated networking can be applied to two NICs.

Note

Ebdsv5-series VMs can burst their disk performance and get up to their bursting max for up to 30 minutes at a time.

Ebsv5 series

Ebsv5-series sizes run on the Intel® Xeon® Platinum 8272CL (Ice Lake). These VMs are ideal for memory-intensive enterprise applications and applications that benefit from high remote storage performance but with no local SSD storage. Ebsv5-series VMs feature Intel® Hyper-Threading Technology. Remote Data disk storage is billed separately from VMs.

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).
