    This IBM® Redpaper™ publication is a comprehensive guide that covers the IBM Power 795 server that supports IBM AIX®, IBM i, and Linux operating systems. The goal of this paper is to introduce the innovative Power 795 offering and its major functions:

    • IBM POWER7® processor, available at frequencies of 3.7 GHz and 4.0 GHz with TurboCore options of 4.25 GHz and 4.31 GHz
    • Specialized POWER7 Level 3 cache that provides greater bandwidth, capacity, and reliability
    • IBM PowerVM® virtualization, including PowerVM Live Partition Mobility and PowerVM IBM Active Memory™ Sharing
    • TurboCore mode that delivers the highest performance per core
    • Enhanced reliability, accessibility, and serviceability (RAS) features that are designed for maximum availability
    • Active Memory Expansion that provides more usable memory than what is physically installed on the system
    • IBM EnergyScale™ technology that provides features such as power trending, power-saving, capping of power, and thermal measurement
