VMware recommends to use the VMware Paravirtualized SCSI (PVSCSI) Controller as the virtual SCSI Controller for data and log VMDKs.
"The PVSCSI Controller is the optimal SCSI controller for an I/O-intensive application on vSphere allowing not only a higher I/O rate but also lowering CPU consumption compared with the LSI Logic SAS. In addition, the PVSCSI adapters provide higher queue depth, increasing I/O bandwidth for the virtualized workload"
