A provider has ran some IOPS test on our VM (without notice) via a script in toad!?  
Is this a known application that is adequate for testing iops over VM's using local storage?

Are there alternatives?

Thanks

All of them!

We use IOMeter, but this may be too complicated, otherwise quick and easy CrystalDiskMark

ok, crystal sisk mark running, what should i be looking at?
also i assume this won't really help with esxi hosts, but standalone servers?

IOPS?

Disk Read and Write specs

it's difficult to generate IOPS for the ESXi hosts, but all your IOPS are in VMs on the datastore!

I would ask Why and How, based on what?

Oh should now, I thought they had evidence to suggest that they had tested, and it go this value.

You've done the calculations, and proved, that your theoretical limit is approx 2000 IOPs, with 16 disks in RAID 6.

In the real world with VMware, ALL I/O is virtualised, so you will get less than the value calculated.

To Increase IOPS, you would need to change RAID type, increase disk speed, and add more disks.

Was a leftover snapshot on the host causing the iops issue.  Was 90, with snapshot deleted ran at 4000.
