Advice needed - UnRAID Server build

post #1 of 6
Thread Starter 
Hey everybody, while I am knowledgeable with system builds, besides what I've been reading up on, some things are a bit new for me on the server side, so I figured I'd ask here. I would like the build to serve a couple of different purposes

1 - NAS storage of files and backups, along with running Plex. I don't see Plex being heavily used at the same time, maybe two devices at once at most.
2 - A VM to run 1 instance of Ubuntu. It would be for learning purposes and basic use.
3 - 2 VMs to run an instance of Windows on each one. One copy of Windows would be for in the event a friend comes over and would like to play PC games on this VM. Another VM would be dedicated to streaming content from consoles/my main gaming PC onto Twitch/Youtube with a connected capture card.

I know the Windows VMs require a beefier video card based on their purposes (Ubuntu not so much), but my question is how many CPU Cores and RAM do you think would be required to run it all confidently. While I have an idea of what it would take for the Windows VMs, I'm not sure about the others. Thank you in advance for the help. ^^

Howdy,

 

I currently have my unraid build running on a sandy i7. I run a few docker apps, and 2 windows VM's, one for random crap and one as an ARK server. 

 

Make sure you get yourself an SSD as a cache drive, or run 2 SSD's in a cache drive raid pool, so you have redundancy. All data that gets written to your array, hits the cache drive first, then is moved to the array in the wee hours of the morning via a mover script.

 

If you want to run multiple high performance VM's, I'd go with a current gen i7 (4c/8t), or if you are thinking you need more power, go with a 6 core i7. Just make sure you buy enough ram, I'd go 32GB if you are going to be running 2-3 VM's.

Also, you will want to run the VM's off of the cache drive(s) so you dont have to spin up your array to run the machines and your drives can sleep.

Thanks a lot for the input. I was thinking of going with a 6 Core (12t) i7, but wasn't sure if that would be enough for the VMs I wanted to run along with the OS itself for the NAS & Plex docker.

If you are going to run a gaming VM and a second VM for video capturing/editing then in addition to needing two separate video cards (one for each VM) you will probably want to dedicate 4 vCPUs to each. So yes I'd say a 6-core/12-thread CPU is a good option, certainly no less.

You will also need to ensure that you have at least 3 separate USB controllers (either on board or add-on). One for each VM and one for your UnRAID flash drive.

That should be plenty. 

 

The NAS portion really uses no CPU cycles, and plex is dependent on a few things; What's the media? (h264 etc), How many streams concurrent, and how many streams are transcoding, as opposed to playing directly. Sounds like a 6 core i7 would fit the bill, or, if I were you, I'd find a used sandy bridge xeon 6c/12t or 8c/12t to throw in there (something like this http://www.ebay.com/itm/Intel-Xeon-E5-2670-2-60-Ghz-20-Mb-8-Core-CPU-Processor-SR0H8-115W-/191762219822?hash=item2ca5eb432e:g:d1EAAOSwll1W0DF3)
