 == Introduction ==
People need powerful computing resources to resolve complex problems. A important issue is how to easy build cheap and effective computing resource. We use DRBL and Kerighed to build SSI cluster. It quick to deploy your cluster environment. You just install them in one machine (Server), clients don't install any OS. Client only setup PXE (network boot) in BIOS, when client finish network booting that your cluster is OK!

*DRBL
||Diskless Remote Boot in Linux (DRBL) provides a diskless or systemless environment for client machines. It works on Debian, Ubuntu, Mandriva, Red Hat, Fedora, CentOS and SuSE. DRBL uses distributed hardware resources and makes it possible for clients to fully access local hardware. It also includes Clonezilla, a partitioning and disk cloning utility similar to Symantec Ghost.
