Testing All Flash SAN Storage large amount of luns at the same time

[alpeshpice]

Hi Robin,

Great work on this tool. Really appreciate your amazing tool.
I was reading thru all the documentation and trying to utilize a tool to benchmark a POC project for my personal project.
I am trying to test All flash SAN storage from windows machine .. I am trying to

simulate small amount of controlled IOPs per disk ... 50-100 IOPS (provided as input .. Mix of random read/write - (30/70) going to almost 500 disks at the same time .

Can you please suggest if any script I can utilize to generate this load as one single job spawning multiplane threads per disk ?

Do I have to use Cygwin or any PowerShell scrip can be utilized?

Hi, Thanks for using dt! The easiest way to test multiple disks or file systems, is by using an external script to create a dt script. This script is executed by dt via the script=FILE option. The dt commands can be per disk or comma separated. When using multiple dt command lines, say one per disk,the enable=async option is required to create jobs. @HPE, we developed a Python script which used dt, spt, and Powershell commands, but that script belongs to HPE. I trust you found the options to control IOPS's, and read/write percentage, right? Please review built-in dt workloads for helpful examples via "dt workloads" I'm now retired, as of January 18th, so have limited access to actual storage hardware. But I can provide some examples and guidance, if desired. Cheers, Robin
