9117-MMA systems that have experienced a failure and auto recovered by rebooting after
Guarding Out the failed CEC enclosures can now have the deactivated enclosure removed so
it can be repaired without powering down the system a second time. Once repaired, the
enclosure can be reintegrated back into the active system without powering down the system
(Cold-node Repair). The resources of the repaired CEC enclosure can then be reassigned to
existing applications or new applications as required. This capability is available to all
9117-MMA systems after upgrading to firmware level EM320_051 or later. With this in mind,
proper planning must be done to ensure that all prerequisites from a server (firmware and
operating system levels) and from an infrastructure (racking, placement, and cabling)
viewpoints are covered.

The POWER6 570 commercial processing workload (CPW) ratings are approximately 70%
higher than equivalent POWER5 systems and approximately 30% higher than equivalent
POWER5+ systems. Improved performance compared to POWER5 and POWER5+ models
is also realized for Lotus® Domino Mail and Calendar Users (approximately 35%
improvement over similarly configured POWER5+ 570 model) and the IBM internal
WebSphere Application Server stock broker benchmark application Trade6 (approximately
45% improvement over similarly configured POWER5+ 570 model). This improvement is
accomplished within the same footprint, electrical power, and cooling parameters as the
POWER5+ system.
With its advanced virtualization technologies, the POWER6 570 can run multiple operating
systems and application environments simultaneously. POWER6 570 shares the following
key characteristics with POWER5+ technology models:
► The ability to run IBM i, Linux, and AIX applications on a single system and to integrate
IBM eServer xSeries® (System x) servers running Windows or Linux
► Advanced Power Virtualization feature for IBM i, AIX, and Linux support
► Micro-Partitioning (up to 10 partitions per processor, 160 per system)
► Simultaneous multithreading (SMT) where a single processor can process multiple
threads
