Hi, I get several machines, some of them are old (actually, not that old, just 2 to 3 years). I would like to build a big cluster like this: I'll divide those machines into three groups, computing, storage, backup storage. As their name, the computing group would be a cluster of physical machines which is responsible to run application. Best of all, the computing cluster would run several virtual machines across the cluster. Thus, the server of the computing cluster would run vmware or xen, and hosting serveral virtual machines inside (note: the no. of virtual machines may more then physical machines). The other machines in the cluster would be diskless (all storage goes to the storage and backup storage cluster), and act as the processing power supplier and the being the terminal to the virtual machines. As I know, such similar architecture can be constructed by using EnSpeed (another OSS project on clustering, http://www.enspeed.com) easily, but one of the requirement for me is hard to fulfill - they require all CPUs of the cluster nodes support VT, and that is not possible in my situation. I've notice that another project, Kerrighed (http://kerrighed.org) do also fit the needs of my computing cluster, I might try it later. So, can I build a such cluster by using GlusterHPC + GlusterFS? or do I need to combine another solution(s)? -- Best Regards. Alsan Wong
