RAID10 Config Recommendations - P408i-a and 8 x Toshiba PX05SRB192

[xwebnetwork]

Hey all! Currently have 8 x Toshiba PX05SRB192's installed in our Proliant DL360 G10 connected to HPE Smart Array P408i-a w/ 2GB cache. Current RAID Array config:

RAID 10
Stripe: 256kb
Block Size: 512b
Write Cache Enabled
HPE Smart Path Enabled

Will be using this server as an ESXi host for a variety of VMs, so mixed use. I've been playing around with different stripe sizes, caching preferences, but figured I would throw it out here too for any recommendations in terms of achieving an optimal, balanced performance. I have yet to try disabling Smart Path, but will do that next and retest.

Anyways, current performance metrics at the above config are below. I feel like it is not performing nearly as well as it should to be honest, especially considering a single drive is rated for 270,000 IOPS Read and 25,000 IOPS write.

There are various factors which we need to take in account here. The drive is non HPE so these Toshiba drives have not been tested with HPE Firmware.
Hence we recommend you to keep the controller F/w and driver of the controller updated to the latest. 
Since you are testing these hence you can try using these drives on a different controller 'if available' to isolate.
Secondly you can try the same controller with an HPE drive and check the IOPS. IOPS does depend on stripe size as well so you can also test with different stripe size to get the best output.
For non HPE drives we request you to check with the manufacturer of the drive also to isolate the issue.
