Generally Available: Ebsv5 and Ebdsv5 NVMe-enabled VM sizes

Published date: May 03, 2023

The Ebsv5 and Ebdsv5 VM series are the first Azure VM series to support NVMe storage protocol.  NVMe support enables these series to achieve the highest Disk Storage IOPS and throughput of any Azure VMs to date.  NVMe is a high-performance storage interface that is faster and more efficient compared to other traditional storage protocols like SCSI, which is the only other protocol that most Azure VMs use currently.  With NVMe interface supported, customers can now use these VMs to achieve even higher VM-to-disk throughput and IOPS performance per core, with up to 8,000 MBps and 260,000 IOPS.  This means these VMs can provide up to three times higher remote storage IOPS and six times higher remote storage throughput performance compared to the previous Ev4 generation.  This enables customers that process extremely data-intensive workloads to process more data on fewer core compute resources, potentially saving them money on infrastructure and commercial software licensing costs.   

These NVMe-enabled Ebsv5 and Ebdsv5 VMs are compatible with all of Azure’s Disk Storage offerings.  NVMe support is available for all sizes and provides performance benefits at 48 vCPU sizes and above. Along with this announcement, two new Ebsv5 and Ebdsv5 NVMe-enabled sizes are generally available as well: 96 and 112i.  The 112 isolated size only supports NVMe protocol. 

NVMe is supported for Ebsv5 and Ebdsv5 VMs in 13 Azure regions: US North Southeast Asia, West Europe, Australia East, North Europe, West US 3, UK South, Sweden Central, East US, Central US, West US 2, East US 2, South Central US. More regions will be added soon.
