Epsv5 sizes series

Epsv5-series virtual machines feature the Ampere® Altra® Arm-based processor operating at 3.0 GHz, which provides an entire physical core for each virtual machine vCPU. These virtual machines offer up to 32 vCPU and 208 GiB of RAM and are ideal for memory-intensive scale-out and most Enterprise workloads. Epsv5-series virtual machines support Standard SSD, Standard HDD, and Premium SSD types with no local-SSD support. You can also attach Ultra Disk storage based on its regional availability. Disk storage is billed separately from virtual machines.

Storage resources

Table definitions

¹Some sizes support bursting to temporarily increase disk performance. Burst speeds can be maintained for up to 30 minutes at a time.
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.

Size Name	Max NICs (Qty.)	Max Network Bandwidth (Mb/s)
Standard_E2ps_v5	2	12500
Standard_E4ps_v5	2	12500
Standard_E8ps_v5	4	12500
Standard_E16ps_v5	4	12500
Standard_E20ps_v5	8	12500
Standard_E32ps_v5	8	16000

Networking resources

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).
