Sun Uniboard CPU/Memory boards with 1.05-GHz UltraSPARC III Cu processors for Sun Fire 3800, 4800, 4810, 6800, 12K and 15K servers provide more power to data center and technical computing customers.With the introduction of 1.05-GHz Uniboards, Sun customers can capitalize on the unique ability to mix CPU speeds in the same Dynamic System Domain in the same server. The combination of Uniboard technology and mixed-speed CPU support with Sun's Dynamic Reconfiguration and Dynamic System Domain technologies means investments in IT infrastructure can be preserved and compute resources can be flexibly provisioned where needed most, resulting in dramatically lower total cost of ownership (TCO) across the IT organization.
