Yes. It's that easy.
Freedom of Choice We recognize that the choice of GNU/Linux distribution is yours. Although we highly recommend SUSE Linux, there are times when other distributions are desired or required. All our cluster management software tools are designed to be easily adaptable to most GNU/Linux distributions*. Run your cluster with your preferred OS, without the inconvenience of learning yet another flavor of GNU/Linux.
Open and Modern Our cluster systems incorporate cutting-edge, open-source software tools including Ganglia and unionfs. Supplemental management and monitoring tools provided by Rocketcalc are also completely open source, and in some cases work in conjunction with Ganglia.
