Throughput for each individual host may be affected by the selected AVS SKU. The AV64 SKU has 100-Gigabit Ethernet (GbE) network interface cards (NICs). The other SKUs have 25 GbE NICs. Individual network flows (such as NFS mounts) may be limited by the 25 GbE NICs.

The following graphs compare the throughput of a single virtual machine on a single Azure NetApp Files datastore with the aggregated throughput of eight VMs, each on their own Azure NetApp Files datastores. Similar throughput can be achieved by a smaller number of VMs with additional VMDKs spread across the same number of datastores.

Traffic latency from AVS to Azure NetApp Files datastores varies from sub-millisecond (for environments under minimal load) up to 2-3 milliseconds (for environments under medium to heavy load). The latency is potentially higher for environments that attempt to push beyond the throughput limits of various components. Latency and throughput may vary depending on several factors, including I/O size, read/write ratios, competing network traffic, and so on.

In a single AVS host scenario, the AVS to Azure NetApp Files datastore I/O occurs over a single network flow. The following graphs compare the throughput and IOPs of a single virtual machine with the aggregated throughput and IOPs of four virtual machines. In the subsequent scenarios, the number of network flows increases as more hosts and datastores are added.
