Linux render slave
show user profile  9krausec
I'm going to be setting up a farm and to avoid OS licensing costs I'm thinking of running Linux on my slaves. The workstation I will be using will be running Windows 10.

There are a few guides to setting a linux render box up, but I wanted to ask here to see if it was an alright idea. Anyone with experience? Is setting a farm up with Linux a solid idea or is it more trouble then it's worth? (I have zero Linux experience).

Software for slaves -

Vray 3.4
Maya 2016 (2017 eventually)
Potentially Deadline in the future

Many thanks for any input on this. New ground and I'm all about learning from people that have experience with something before I spend a substantial amount of time to find out it won't work or is more trouble than it's worth.

I don't have experience using Linux for VRay rendering on my own, but a few thoughts crossed my mind:

I remember a guy stating on facebook that he pretty much renders all his stuff on demand using Amazon nodes with the help of some custom scripts. If having a local farm is not a necessity, rendering in the cloud may be a viable option to you, maybe you want to shoot him a mail

On the other hand there is also this blog post you may find useful:

EDIT: Sorry didn't see you are using Maya, but it boils down to VRay standalone + Deadline so may still be worth reading.

never get low & slow & out of ideas

Thanks man.

I just picked up 5 Dell Poweredge 1950 III servers. My logic is this-

For medium sized animations that aren't for a hard deadline (or extra large stills) I'll render locally on my mini-farm.

For projects that are massive and would take forever to render even with my setup, I'll using the Amazon cloud service (eventually when it gets setup). Servers were at a good rate and software licenses are still needed for the cloud so it's not a waste to get the slaves setup with the appropriate software licenses.

Thank you though. I'll read through the articles.

Linux is the only way to go. It's really not that hard to get done...

What shocked me was finding out how much faster rendering under Linux was using Blender than using Windows.

What shocked me more was that doing the same render on Windows and a VM with a Linux distro saw the VM rendering faster than running naively on Windows.

What shocked me most of all was that using a Virtual Machine with Linux (mint) running the Windows version of Blender under WINE was still faster than doing the same render on native Windows.

So, rendering emulated Windows in a virtual linux machine was faster than just rendering in Windows. This is crazy.

This was CPU only rendering, obviously.

speaking of software costs, did you purchase more Vray nodes.

People often forget that the software limits your core uses until you render on farm.

I guess that was vague do to my sunday funday whiskey
I mean you have to pay for more render nodes.
You just can't make a farm and hit go i think Vray regular license is 1 workstation nodes, he'll have to pay to put it on his server blades.

At least that's what I had to buy at a job couple years back.

I manage, run technical support and deal with operating costs of the Vray farm at the office. ;) Since Vray 3.0, nodes are no longer free and I'm well aware of this.

I alway thought the whole node costs was just evil and greedy.

I'd rather pay for nodes to cover the overhead of getting so much with each updated version of Vray for "free" over not getting those updates.

Not saying that paying for nodes and the updates have a correlation (although I'm sure they do somewhere), but I do not mind paying those additional costs to Chaosgroup for what they are providing.

Now Realflow charging on a per core basis is just stupid in my opinion. It could be way worse if Vray decided to license per core. Chaosgroup wants/needs to turn a profit, but I hardly would consider them greedy. (not saying you were calling out Choasgroup specifically, but I am as Vray is the only renderer I use).

I'm interested to see how AD is going to integrate pricing for Arnold into 3ds/Maya.

The way I see it:

It's like a pencil company that charges you for each piece of paper you can write on.
