While clusters have revolutionised High Performance Computing, the standardisation of operating systems has also made an impact. Linux deployment has seen worldwide acceptance aiding its growth and integration. To accomodate this market requirement, VA Technologies has a wealth of experience in Linux Clustering and can preload systems with all of the major Linux distributions. In addition, system management becomes a factor in data centres due to the large number of systems involved in a cluster. This introduces a new category of underlying problems, including load balancing and hot-swap systems cooling and power consumption. VA Technologies specialise in making recommendations and designing solutions to meet these challenges.
