Sun's Uniboard CPU/Memory board, which is common throughout the entire Sun Fire Midframe and high-end server family, is a differentiated offering that enables customers to provision resources where they need. Hot CPU capabilities and support for mixed-speed CPUs enable customers to upgrade to the USIII Cu processors without a reboot, which increases availability, enables seamless re-allocation of compute power and eliminates planned downtime for these upgrades - a common occurrence in IT environments running data-intensive applications.
