Hi! I have a problem that I was hoping I could get some advice on. In particular, where to start looking...
I inherited a Rocks Cluster which I am trying to make semi-usable. There are 31 nodes in the cluster, so in order to create the cluster network, two Dell switches are used -- a PowerConnect 5224 and a PowerConnect 5324. The head node and most of the computer nodes are plugged into the 5224, and the rest are plugged into the 5324 which then is plugged into the 5224. The problem that I'm having is that the clients on the 5324 cannot be PXE booted properly. If I plug them into the 5224, let them boot and install, and then plug them back into the 5324, they work correctly, until the next time I need them to reboot (to add a package, or something). I assume there is some kind of packet that is not being properly forwarded by the 5324 (or not being allowed by the 5224). What I would like is to convince the two switches that they are really one big(ger) switch, so they don't block anything from going around. Unfortunately, I really don't know much about networking beyond the basics -- in particular, I don't know the terminology. Looking at the configurations of the switches, I see things like "spanning-tree", "bridging", "trunks", etc. What should I be looking at? I tried to Google various things, but I'm not convinced I even know where to start -- at least, nothing I've found seems to address my question, or at least make sense to me.
