Leadership POWER6 performance
The leadership performance of the POWER6 processor—the
world’s fastest chip—makes it possible for applications to run
faster and be more responsive which can result in business
advantages and higher customer satisfaction. In addition, a single system can now run more applications and can reduce the
number of required servers and reduce infrastructure costs. The
improved performance with POWER6 technology also enables
clients to get more processing power with fewer processors
resulting in lower per core software licensing costs.
Application availability
The IBM Power 520 Express is designed with capabilities to
deliver outstanding application availability and allow more work
to be processed with less operational disruption. The Power 520
Express capabilities include recovery from intermittent errors or
failover to redundant components, detection and reporting of
failures and impending failures, and self-healing hardware that
automatically initiates actions to effect error correction, repair
or component replacement. In addition, the Processor
Instruction Retry RAS feature provides for the continuous
monitoring of processor status with the capability to
restart a processor if certain errors are detected. If required,
workloads can be redirected to alternate processors, all without
disruption to application execution. In combination with the
optional PowerVM Enterprise Edition with Live Partition
Application Mobility, the Power 520 delivers near-continuous
application availability.
Flexibility and choice of operating
environments
The flexibility to use leading-edge AIX, IBM i, Linux for Power
and x86 Linux applications in a rack-mount or deskside form
factor broadens the application offerings available and increases
the ways clients can manage growth, complexity and risk.
Leverage these easy-to-manage, easy-to-secure and highly
reliable operating environments to run thousands of proven
industry solutions that are sure to fit the needs of almost
any business.

Improved utilization and energy
efficiency
As the price of energy increases and resources are limited,
energy efficiency through better utilization has become more
important. The leadership performance of the IBM Power 520
Energy Manager™ software exploits POWER6 processorbased EnergyScale technology which monitors power/
thermal utilization and conserves energy by enabling power
management features for improved system utilization and
energy efficiency.
Express translates into greater available computing power for
applications and allows you to leverage PowerVM Editions and
virtualize your infrastructure to improve server utilization and
energy efficiency. Supported by the AIX, IBM i and Linux
operating systems. PowerVM Editions provide an innovative set
of comprehensive systems technologies and services designed to
enable you to easily aggregate and manage virtualized resources.
Micro-partitions enable the Power 520 to be split into a flexible
and highly utilized system. IBM Systems Director Active
Integration and simplicity
With IBM i, the Power 520 Express becomes a highly scalable,
virus resistant server that integrates a trusted combination of
relational database, security, web services, networking and storage management capabilities. The preintegration and testing of
the IBM i operating system is a key factor in enabling companies to deploy applications faster and maintain them with fewer
staff. Running applications based on this IBM i operating
system has helped companies over many years to focus on
innovation and delivering new value to their business.
