I'm thinking about load balancing and redundancy. My LTSP setup is very stable, but catastrophes do happen, and if that server goes down, the whole world is down.
For load balancing, there are two options I am thinking about. 1. MOSIX clustering (www.mosix.org) - this will transparently migrate processes from server to server (or workstation) to balance the load over the available resources. This seems like a cool way to do it because it will spread the load accross multiple boxes automagically. 2. Application servers - In this scenario, you could leave your current stable server running as is (hey, if it ain't broke....), and just use rsh or ssh to run the additional software on the new box. You could add links to the users desktops with the rsh or ssh commands ready to go. The extreme case of this would be to set up a server for each application (star office server, mozilla server, etc.) I'm looking for ideas to provide redundancy, so if my main login server goes down, users could simply log in again to a secondary server. I've been looking at using the XDM chooser to allow users to choose between login servers based on load, but ideally, the users wouldn't have to know that there were multiple servers, they would just log in again and keep on truckin'. Any ideas? As for the dhcp server, you would really only need to run the dhcp server on one machine and then just set the server option to the appropriate machine to boot from. I think the dhcp option is next-server 192.168.0.254 Thanks, Derek ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/ _____________________________________________________________________ Ltsp-discuss mailing list.
