Just try to boot linux with pvscsi driver.
but i didn’t notice speed/cpu utilization difference.
my real scsi card is lsi ultra320.
vmware said pvscsi won’t suit DAS systems.
maybe they are correct. it seems not worth to use it in DAS.

It may only work with RHEL5, according to the KB article… You probably have to build a custom kernel for your specific distribution otherwise. I would install a single drive for the OS volume non-PVSCSI(Windows or Linux), then put my application data on a 2nd PVSCSI attached drive (Exchange, SQL, MySQL) to get the most performance for my application.

I’ve got boot PVSCSI working fine in Microsoft’s newer OSes but have not figured out how to get linux to boot on PVSCSI. Funny that’s so much harder. Why would I not want the fastest (virtual) drivers for the OS?
