Our test indicates that the maximum I/O that a customer can drive from multiple clients, against a single Azure NetApp Files volume is around ~317K 8KiB IOPS.
Our sequential test was done using the exact same tests and procedures. In this
Our tests show that Azure NetApp Files performs at minimal latency regardless of whether the Azure virtual machines are in the same Azure Data Center or Campus as the ANF storage system or not (i.e adjacent or non-adjacnet). An Azure NetApp Files volume is able to generate ~319,000 IOPS at only 1.5ms latency for adjacent virtual machines and ~290,000 IOPS below the 2ms latency mark for non-adjacent virtual machines.

The graph shows Oracle database performance when using Azure NetApp Files on the Oracle SLOB benchmark. Running a mixed read/write Oracle workload in a single Standard D64s_v3 Linux VM instance is able to drive 71,000 file system IOPS at sub-0.5 msec latency in a single NFS volume, and up to 218,000 IOPS while still below 2.5 msec. Adding a 2nd Azure NetApp Files data volume enables scaling performance even higher to 310,000 IOPS and beyond while latency remains well below 2 msec.
