Thinking about moving my UnRaid to ESXi 6.7

Hi all

 

I've just finished building my hardware upgrade for UnRaid, from a Gen8 MicroServer to:

 

Fractal Design Define R6 Case

Intel Xeon E5-2650L v3 (10 core / 20 threads)

ASUS X99-WS/IPMI

32 DDR4 Memory

4 x 6TB drives and a 240GB SSD for cache.

 

One of the reasons for upgrading is for to be able to run some VM's (Windoze, GNS3 and Hackintosh) I'm having issues trying to get GNS3 working which lead me to a thought of running UnRaid as a Guest in ESXi 6.7. From reading here quite a few people has done it but as a general question how stable is it?

 

I've never hammered  my currently setup, I use Plex, Sonar, OpenVPN, backing up the family pics etc, the usual stuff.

 

My thoughts are: I used a IBM ServeRaid M1015 flashed in IT mode in the Gen8. I'm thinking about passing this through to the Unraid as a guest so the drives should work as they do now. I'd like to use maybe something Plop to boot the USB and then if I need decide its not for me I can still boot UnRaid as host .

 

I've been reading the sticky's here and I think it's a better fit for my needs moving forward. Is Plop still the best usb bootable app? How much memory should I assign? 8GB seems to be my thinking.  I don't use much transcoding so would 2 maybe a 4 core for UnRaid be OK?

 

As for ESXi I have a 120GB SSD which I can add to the motherboard's Sata as the host OS.  One of the reasons using the Low power Xeon and having the drives power down when not needed is to keep it low power consumption as possible, will ESXi keep everything running max or  will I be able to ram up and down as needed? Any other useful tweaks?

 

Thanks

i'm running my two unraid as VMs on top of ESXi for years.

i'm using PlopKExec without problems.. https://download.plop.at/plopkexec/plopkexec.iso

if you don't run any VMs, 4GB would be reasonable, but you can add more latter if you want. but according transcoding - you should just run some tests to see, how much it eats your CPUs, start with 4 vCPU. Free version of ESXi have a 8 vCPU limitation. i'm trying avoid any transcoding in my plex server. but you can go new unraid nvidia route and transcode with your GPU - check the plugin forum page.

if you pass your IBM 1015 to unraid VM, then ESXi has nothing to do with it and drives connected to it - unraid manages spindowns of these drives. and according SSDs attached to host - i have two in my server and never noticed any problems with them.

Hi Uldise

Thanks a lot for the really useful reply. Funny enough I have already download PlopKExec.iso :)

So I've been running UnRaid as a guest for about a week. Mostly it's working great, I do have an issue with network host mode (think I've messed up my routing table)

 

Should I look to install VMware Tools? Apart from Esxi shutting down UnRaid gracefully does it do anything else?

 

Also is there anyway to fix:

 

"Your CPU is running constantly at 100% and will not throttle down when it's idle (to save heat / power). This is because there is currently no CPU Scaling Driver Installed. Seek assistance on the unRaid forums with this issue"

i think, that's the only reason i have Open VM tools installed. look at this thread from the end, and you will find download for your unraid version.

i see this message on my server too. but if your CPU is running fine, and you see no CPU usage at idle on host/unraid VM, then you are fine. cos unraid under ESXi is not officially supported.

I have an updated, much simpler, VMWare tools.  I will try to post it tomorrow.
