Paravirtual SCSI (PVSCSI) adapters Local Storage VS SAN
Hi,
According to the document :
https://kb.vmware.com/s/article/1010398
PVSCSI adapters are not suitable for DAS environments.
PVSCSI adapters are best for environments, especially SAN environments
If I setup a new server with Local Storage ex : SSD Drive RAID 10 setup and I created a VM with PVSCSI boot disk and data disk.
My questions :
Why it is not suitable for local storage ? I will not see any significant gain of performance ?
Any technical issue we might expect ?
Not suitable means not functional or not supported ?
Thanks,

Hi,
I Agree with your comment but I still do not understand why VMware add a comment it’s not suitable for DAS and it’s more for SAN. I’m trying to understand why thoses comments are there especialy ?
What can be the issue with DAS? Number of
VMs?
Thanks

PVSCSI adapters are high-performance storage adapters that can result in greater throughput and lower CPU utilization. PVSCSI adapters are best for environments, especially SAN environments, where hardware or applications drive a very high amount of I/O throughput. The VMware PVSCSI adapter driver is also compatible with the Windows Storport storage driver. PVSCSI adapters are not suitable for DAS environments.

You can try it, but it really depends on the workload in the VM, if you see any performance increase!
If there is a driver for the VM, it's supported. Whether it gives you the performance you require is only a matter of testing.
