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.

Storage resources
Table definitions
1These sizes support bursting to temporarily increase disk performance. Burst speeds can be maintained for up to 30 minutes at a time.
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.

Networking resources
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).
