High Performance Render Farm networking


Jun 22, 2014
Hey Guys,

I have a render farm with 150 clients and it keeps getting larger over time.
My main server where all the clients are working off of has a 10gbps Mellanox X2 card.
But all the bandwidth of that card is used up. I want to add more clients but the server network connection is the bottleneck.
What are the cheapest options with used equipment in which i can somehow get like a 40gbps connection out of my server to a switch with a 40gbps connection?
Then i would like to take a 10gbps connection from the 40gbps switch to switches at each rack with the render clients.
All ideas are welcome.
