cluster servers

[3dp]

anyone here any experience or knowledge of running and setting up a group of servers as a cluster network i'm going to adding some rack servers shortly for more horsepower but in the same way that i use network rendering and or frame splitting renders in max i'm wondering if it's the way to go for number crunching in radiosity calcs by throwing 20+ processors at a project to calculate it and render it

that is if i understand the cluster process correctly as 2-300 meg rad solutions cause hell on the network to the point they are not viable to render and if they are taking 1-2 hours to calculate

then again i think i need to clone my workstation drive across the rendernodes to minimise network traffic thats got to help
