Jul 07,  · 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 Author: softininc.org This behavior does not mitigate the overall performance gain of using VMware Paravirtual SCSI controllers as compared to other SCSI controller options. If you have virtual machines with VMware Paravirtual SCSI controllers, those virtual machines cannot be part of an MSCS cluster. Feb 07,  · VMware Paravirtual (aka PVSCSI) – this vSCSI controller is virtualization aware and was been designed to support very high throughput with minimal processing cost and is therefore the most efficient driver. In the past, there were issues if it was used with virtual machines that didn’t do a lot of IOPS, but that was resolved in vSphere
