I'm about to build a render farm with about 40 nodes using a beowulf-like architecture for the cluster. My problem is, I'm not sure about the topology of the network I'll have to use. Is it a good idea to use a NAS? And if yes, is it ok to connect it to just the network switch,or should I connect it to every node seperately? And moreover, am I going to need an extra server node apart from the master node of the cluster?
Excuse me if some of my questions are silly but I'm completely new to all of this.
Thanks in advance
(p.s budget is about 60.000 euros without including cooling system and power costs)
