VM running off of single, dedicated disk...

I have a W10 VM that I use (try to use, anyway...) to render videos in Adobe.  It's just on the array and the disk speeds are SO...INCREDIBLY...SLOW...that it takes an unbelievably long time to render.  I stopped a render yesterday after over 2 hours because it was BARELY making progress...my flaccid dual core laptop did the entire render in that same amount of time.  At the rate the server was going, it would seriously have taken 10 hours?...maybe 12?  I don't even know.  It's INCREDIBLY slow and, when I look at resource manager, I notice the disk access is pegged.  Disk speeds seem to be the culprit. 

 

So...I have a spare Samsung 860 Evo laying around.  This got me thinking, how could I install it and dedicate it to the VM?  What I'm wondering is, is it possible to assign that disk ONLY to that VM?  Maybe using "unassigned devices"?  Also, would it be possible to move the VM onto the SSD after I install it or will I have to create a new VM?  No big deal if I have to reroll a new VM.

 

Thank you!!

What do you mean by that? Do you mean that the VM's vdisk is on the array? If not, where is it? Or do you mean that the source and destination files for the render are on the array?

Yes, the vdisk and the source files are on the array.  I'd like to dedicate an SSD to the VM so the VM can run off of it and I could put the source files on there for rendering.  I'm hoping that would make the thing render as fast as it should.

Maybe I could just install the SSD and put the source files on it...maybe that would help.  How would I "attach" that disk to the VM?

No wonder the performance is atrocious. Install your SSD in your server and when your start it up allocate it as the cache disk. Then you can change the system and domains shares to cache:prefer (that's the default, anyway) and run the mover (make sure the VM service is temporarily disabled first).

I have an NVMe SSD in the server that was intended to be the cache drive but I'm having trouble getting the BIOS to recognize it as it's installed via PCIe. 

 

The extra SSD I have is SATA.  Would I be able to assign it to the VM somehow?

There are three components to running your rendering VM (the system files, the VM boot disk and the data files) and at the moment you are running them all from the array. If you set your SSD as a cache you can move all three of those components onto it. The system files are in the system share, the VM boot disk is in the domains share. Once you've done that you can choose where you locate the input/output files for your renders. For example, there might be enough space on the VM's vdisk C : drive, or you might want to add a D : drive to accommodate them. (I had to put a space before the colons otherwise a stupid smiley is substituted - 😄 😧 )

I have a NVME SSD and it for the last year and worked great, till about 3 months ago, on a power off it does not come up on most boots under unassigned devices.  I have an AMD processor and an ASRock AB350 Pro4. Is anyone else having issues with NVME disks not being found?

This has nothing to do with this thread so start your own topic and include your diagnostics zip file (Tools -> Diagnostics).

Got ya.  I'll give it a shot this weekend.  Thanks!
