How to use VMWare PVSCSI driver in Windows Virtual Machine – Tyler Woods

Unless the VM is really busy, you won’t see much difference. Click OK to save your changes. With all of the different variations of virtual controllers now available in VMware, I wanted to perform a simple test of disk performance benchmarks when using all three controllers on the same virtual machine to see if the controllers performed as expected and if there is actually performance improvements in using the new NVMe controller vs the PVSCSI or ParaVirtual SCSI controller with a virtual machine that is truly backed with an NVMe drive.

Is this for both the AD server and the clients? The virtual machine was powered down, controller changed, booted back up, and allowed to login and sit for a couple of minutes to make sure no processes would be competing for disk performance.


These controllers are best suited for high-performance storage environments. Make sure you previously mounted the “Windows. Paolo Maffezzoli posted an update 22 hours, 4 minutes ago.

Vmwarw step is to change the default Network adapter type which is E by default. It will be interesting as well for VMware to update some of the documentation comparing the various virtual controllers from their perspective. Perhaps another post with a test, clarifying this, would help. This disk is not a system disk, so the VM will boot normally, and the Windows operating system will automatically find the drivers it can use to install this VMware Paravirtual controller.

Result — minimum differents.

Or only for certain cases such as DB servers? Please ask IT administration questions in the forum. To access boot disk devices attached to a PVSCSI controller, verify that the virtual machine has a Windows or Windows guest operating system. Are you doing some specific supported optimization to your VMs within your ovscsi ESXi and vCenter Server 5.

Windows Server 2016 Install VMware Paravirtual SCSI controller

The driver path will display within the setup window. After running all three tests with the different controllers, I had some very interesting results when comparing between the three. Are you an IT pro? In some operating systems, before you change the controller type you need to create a virtual machine with an LSI Logic controller, install VMware Tools, then change to paravirtual mode.

Instead, you can add them via the Settings app or by using PowerShell.
