Epsv6 sizes series

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

Important

Azure Virtual Machine series Epsv6 is currently in preview. See the Supplemental Terms of Use for Microsoft Azure Previews for legal terms that apply to Azure features that are in beta, preview, or otherwise not yet released into general availability.

For more information and to sign up for the preview, please visit our announcement and follow the link to signup.

The Epsv6-series virtual machines are powered by Azure’s first-generation Cobalt 100 processor, delivering outstanding performance for memory optimized workloads. The Azure Cobalt 100 processor operates at 3.4 GHz and provides an entire physical core for each virtual machine vCPU. These virtual machines offer 8 GiB of memory per vCPU and a wide range of vCPU sizes. These VMs are best suited for memory-intensive scale-out and enterprise workloads, such as relational database servers, large databases, data analytics engines, in-memory caches, and more. Epsv6-series virtual machines support Standard SSD, Standard HDD, and Premium SSD disk types. You can also attach Ultra Disk storage based on its regional availability. Disk storage is billed separately from virtual machines. For more information, see pricing for disks. Epsv6-series virtual machines offer up to 96 vCPU and 672 GiB of RAM. These VMs come without local disk, providing a better value proposition for workloads that don't require local temporary storage.

Table definitions

• ¹These sizes support bursting to temporarily increase disk performance. Burst speeds can be maintained for up to 30 minutes at a time.
• ²Special Storage refers to either Ultra Disk or Premium SSD v2 storage.
• 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.
• 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.
• To learn how to get the best storage performance for your VMs, see Virtual machine and disk performance.

Network

Network interface info for each size:

Size Name	Max NICs (Qty.)	Max Bandwidth (Mbps)
Standard_E2ps_v6	2	12500
Standard_E4ps_v6	2	12500
Standard_E8ps_v6	4	15000

Networking resources

• Virtual networks and virtual machines in Azure
• Virtual machine network bandwidth

Note

Accelerated networking is required and turned on by default on all Epsv6 machines.

Table definitions

• 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).
