Better virtual controller for True/FreeNAS Boot drive

[Alex_K]

(old) Guides on virtualizing FreeNAS say we should use LSI Logic Parallel, no explanation.
Checked up 5 virtualized FreeNAS instances I maintain, and on all of them I used LSI Logic Parallel. I _do not remember why_. Its possible just followed guides.

But just now as I tentatively decided to give 12* another look, and maybe LSI Logic SAS is now better, somehow?

It does not install onto Paravirtual, and Bus Logic is "not recommended for that OS", leaving two equal options, at the 1st glance.

LSI Logic Parallel
LSI Logic SAS

Or not equal?

I assume Free/TrueNAS may try to do _things_ with LSI Logic SAS assuming the SAS is real, like M1015, and VMware may frown at that. But that only intuitive speculation.

If someone with undersatning could elaborate, which is better for TrueNAS 12*, and possibly how different it goes for 13* and FreeNAS, and how, that would be appreciated.

Also if answer would be different between 6.0 and 7.0 ESXi.

I don't think spending time thinking about it is productive... the boot media and virtual controller connecting it need only be selected due to having a supported driver in TrueNAS.

As far as I can tell, both would equally be covered by existing drivers.

Which is better from a VMware perspective may further guide a selection, but I imagine it's a complete waste of time in terms of any benefit you will see compared to time spent working it out.

+1 to what @sretalla says. I have run TrueNAS CORE on Vmware for years (since the 9.x days). My setup uses the LSI Logic SAS virtual SCSI adapter for the boot drive. It works fine with no noticeable performance issues.

Also, there probably isn't anything the iX folks can do about support for paravirtual SCSI as that is definitely a FreeBSD thing and would depend on the FreeBSD and/or VMware folks developing FreeBSD drivers for the VMware paravirtual SCSI adapter
