Well, here’s the thing:
I had a Windows 10 vm that received an NVMe SSD drive as passthrough. Windows was installed on it and performance was native like, as expected.
Then, realizing that 1TB for C drive of Windows is a complete waste of precious fast storage and since I had to reinstall the damn thing anyway, I stopped passing the drive through as a pcie device and created a data store on it instead.
When specifying a drive of 250GB for Windows, I saved it, eagerly zeroed, on the NVMe store.
I don’t know what I was expecting but 1,6 GB/s is not it. I was getting 3,5GB/s on metal.
Is this a normal situation or is there something I’m missing?
The P900 has all the performance needed BUT I DID shrink the CPU’s count a bit from the previous installation, from 12 vcpu’s to 8… could that be it?
EDIT: syntax and some new details, the drive is Logic SAS, not Parallell and certainty not Paravirtual. Could this make a difference? I have VMWare tools installed. Can I change the controller type with Windows having the drivers and expect it to wake up again?
