Thx for the link. Looks like there are some limitations when I get it
in the correct way: with Linux only two nodes are supported.

How many do you want to connect?

Actually, up to four (4) nodes are supported.  We have three (3) nodes, all connected to form a single, multinode host, with 12 six-core processors (72 cpus, in total) and 384GB of RAM. It (bigone) runs RHEL/5.4, and will soon be connected to a NexSan SATAbeast w/14TB of storage.
