The server pool is just a load-balancing and security thing. When a user starts up a Sage session, Sage selects on of the entries in the server pool (using random or round-robin load balancing, I think) and uses that to start the user's session. At least, that's how it was used to work. I don't know if the new notebook code changed things. In general, there is no connection between the number of notebook users and the number of server pool entries. The nice security thing about having lots of server-pool entries even when on the same server is that you can make each a separate unix account. Then simultaneous logins likely won't be running on the same unix account, and so can't mess with each other's files in a malicious (or nonmalicious) way. At least, I think permissions are set up so the workspace is not writeable by other people.
