There are many, many options for doing this, and each depends heavily on what it is you're trying to do. There is no "magic cluster software" or one size fits all solution. Each thing you want to do will likely have a different set of requirements and each tool a different set of benefits or features. You'll need to clearly define the services your linux machine currently offers (ie http, samba, svn, etc), and then what types of fail over, load balancing, load sharing, or high available you might wish each to have. You also need to consider what your client systems can tolerate (ie, HTTP fail over is quite easy, as is HTTP load balancing, but something like samba fail over may not be so easy). If your system is so important to require fail over or HA, then you may actually want to dedicate a set of servers for each major service offered (since you can then drill deeply into that service's best fail over options rather than trying to pack 5 different solutions for 5 different services). If the actual need is more performance or throughput, then a single larger server with a good backup strategy will likely be far easier to impliment than trying to "cluster" several smaller machines. So, list out some services and perhaps we can point you to some specifics for further reading. -- Ted Deppner http://www.deppner.us/ _______________________________________________ vox-tech mailing list [email protected] http://lists.lugod.org/mailman/listinfo/vox-tech
