This IBM® Redpaper™ publication is a comprehensive guide covering the IBM Power 770 (9117-MMC) and Power 780 (9179-MHC) servers supporting IBM AIX®, IBM i, and Linux operating systems. The goal of this paper is to introduce the major innovative Power 770 and 780 offerings and their prominent functions, including:

  • The IBM POWER7™ processor available at frequencies of 3.3 GHz, 3.44 GHz, 3.72 GHz, and 3.92 GHz, and 4.14 GHz
  • The specialized IBM POWER7™ Level 3 cache that provides greater bandwidth, capacity, and reliability
  • The 1 Gb or 10 Gb Integrated Multifunction Card provides two USB ports, one serial port, and four Ethernet connectors for a processor enclosure and does not require a PCI slot
  • The new Active Memory™ Mirroring (AMM) for Hypervisor feature that mirrors the main memory used by the firmware
  • IBM PowerVM™ virtualization including PowerVM Live Partition Mobility and PowerVM Active Memory™ Sharing
  • 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
  • Enterprise-ready reliability, serviceability, and availability

Professionals who want to acquire a better understanding of IBM Power Systems™ products should read this paper.

This paper expands the current set of IBM Power Systems documentation by providing a desktop reference that offers a detailed technical description of the 770 and 780 systems.
