In WebSphere land at least, a cell is a group of computer systems, a node is one computer, a server is one instance of WebSphere. A cell can have one or more nodes, a node can have one or more servers. I'm not sure if cell == cluster necessarily. My old team said clone (noun) instead of server. We had a cell of 3 computers with 2 nodes each for six clones. Just to confuse things, the "computers" are now virtual.

This very brief WebSphere Architecture page is as close as I found to a reference on this.

A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
