Hi again Vladan, was hoping you could answer my second question as well. Is vSAN considered DAS as it's directly connected to the chassis or SAN because that's how it's presented to the ESXi hosts?

Good point!

I just tested it using JEA configuration and it worked great!

Thank you!

PVSCSI and LSI Logic Parallel/SAS are essentially the same when it comes to overall performance capability.  PVSCSI, however, is more efficient in the number of host compute cycles that are required to process the same number of IOPS. If you have a very storage IO intensive virtual machine, this is the controller to choose to ensure you save as many cpu cycles as possible that can then be used by the application or host.

IMHO you can test it. Clone the VM, change the controller,  and check the stats, CPU usage, IOPS etc. Unless the VM is really busy, you won't see much difference. Either on SAN or DAS.

Great article!

I have a similar issue and want to change to Paravirtual but currently running on DAS, what is the reason why paravirtualization is not recommended for DAS?

Thanks!

Thanks for the insight - it is very helpful.

Just so you know, the reason the download function doesn't work in a remote session is because of the 'double-hop' restriction in the default configuration of powershell endpoints.

If you properly configure a Just-Enough-Administration (JEA) endpoint, you can do the whole thing without resorting to scheduled tasks. The JEA endpoint needs to be configured to RunAsVirtualAccount and would need either the "FullLanguage" LanguageMode, or have the commands wrapped in a module/visible functions.
