The idea behind LTSP is to support thin clients and unfortunately, redundancy is extremely hard to implement because the expectations aren't compatible. There is no standard way to pick one server over another during a network boot that I know of.
Another issue, what specifically does one go the next version of LTSP for? What is lacking in the current version that you need from the next version? Sometimes, it is better to patch an older version that works than it is to move to a newer version with new bugs. One option, you need a host OS on the server that doesn't run LTSP and an emulated Linux environment(s) that does. This is a possible way to fire up one server or the other so that the server you want is the one you are running. Problem is, how do you test the new server while you let your clients use the old? The immediate appeal of running LTSP on the server under emulation is that you don't have to reboot. The downside, well you have to have a hefty enough computer and you have to understand emulation on top of understanding LTSP. If you can emulate a subnet or if you can run a second subnet and a test client on that secondary subnet... You should be able to emulate both LTSPs as long as one runs on one subnet and the other runs on another subnet. DHCP could be a problem though if you give out random IP addresses. Maybe on the secondary subnet you can do static configuration??? So I'm saying do static configuration on your test subnet and dynamic configuration on your production subnet. Looks like this can work. BTW: If you have two physical subnets and you partition the servers between them, both can be dynamically configured. Network cards are pretty cheap these days and memory/hard disk space/processing power is getting pretty cheap too. Only when you share media for two different IP subnets does dhcp become problematic. ------------------------------------------------------------------------------ Using storage to extend the benefits of virtualization and iSCSI Virtualization increases hardware utilization and delivers a new level of agility.
