To test the connectivity from the host to the FlashArray, you can use D ISKSPD for a basic plumbing test. DISKSPD is a storage load generator/performance test tool from the Microsoft Windows, Windows Server, and Cloud Server Infrastructure Engineering teams.

Using the DISKSPD utility is not advised to do performance testing. In the use case mentioned here, it is to simply test the connectivity and plumbing.

Note:

DISKSPD is not recommended for performance testing. The use case mentioned here is to simply test the connectivity to the FlashArray.

Running diskspd with the below example command line will generate I/O to evaluate connectivity. The <DRIVE_LETTER> in the command line should be the drive letter of the newly connected volume. To learn how to set up a drive letter for a newly connected volume see Working with Volumes on a Windows Server Host.


 .\Diskspd.exe -b8K -d3600 -h -L -o16 -t16 -r -w30 -c400M <DRIVE_LETTER>:\io.dat

The results of the plumbing test should generate similar output as below.

The host can also be monitored using the Purity CLI with the below command.


pureuser@myarray-ct0:~# purehost monitor --balance
