Before deploying workloads on PowerStore, it is a good idea to validate the I/O path between the server and the array. Running a large block sequential read test using small files should saturate the path between the server and the array. This test verifies that all paths are fully functional and can be used for I/O traffic. Run this test on an isolated server and PowerStore. Running this test in a production environment could cause significant performance issues for active workloads. To validate the I/O path, run a large block sequential read test using the following guidelines:
If the displayed throughput matches the expected throughput for the number of HBA ports in the server, the paths between the server and PowerStore are set up correctly.
