SSD/HDD testing help request


Hey all

I'm wondering if anyone would be so kind as to spin up a VM on their AHV system and run a CrystalDiskMark (6.1) test (9 pass / 50mb) on the hard drive in the VM?

The back story here is we are seeing much better I/O to our 4 year old ESXi system then we are seeing with the brand new 4 node AHV cluster we have. It seems to be grossly affecting one of our Oracle DB's abilities, and we have been trying to figure out if something is very wrong in our setup. Nutanix support says Dell has to deal with this, but Dell doesn't have a lab to run the test and give us a comparison.

So if someone would want to run a quick 9 pass 50mb test on Crystal I could at least know if this was a standard NTNX thing, or if we really have a serious problem.

Thanks

Hi @it-erthcorp

I ping the team and you should have someone reach-out to you shortly. 👍
Hi Aluciani,
we have not heard anything yet.

we are looking to see if the issue is with our configuration or our testing.

we want a single threaded test done with 9 passes, of a 50 meg file, on random writes. we are seeing what we would call sub par performance.

i do not know if this is still relevant or not but i wanted to share my result on 4 node NX-3060-G5 running Vmware ESXi 6.5 so you can compare it with your result and if you can share yours so i can have an idea about my PoC performance
