Red Hat Enterprise Linux
on Power Systems
Capitalizing on the benefits of IBM Power Systems
is now easier than ever

New technologies
are driving change
• Increased demand for big
data analytics, cloud, mobile,
social and security solutions
might require you to rethink
your enterprise infrastructure.
• Responding to market shifts
requires innovation.
Together, IBM and
Red Hat have led the
way in contributing
to the open communities
that are powering these
innovative new solutions.

• Reliability: Reduce risks with
a tested, proven, predictable
and secure open platform.
• Flexibility: Tailor your Linux
infrastructure and adapt
to changes.
• Ecosystem: Connect with a
large ecosystem of partners,
customers and experts.
Why do organizations choose
Red Hat Enterprise Linux?

Red Hat® Enterprise Linux is the world’s
leading developer and supplier of open
source software for enterprise IT.
• 70% of the enterprise
Linux market
• 90% of Fortune 500
companies use
Red Hat products
and solutions1

Now more than ever, IBM®
Power Systems™ is a compelling
platform for your Linux environment:
• Greater choice and flexibility: Red Hat Enterprise
Linux 7.1 now supports little endian mode for
the newest Linux-only Power Systems servers
equipped with IBM POWER8™ technology.
Capitalize on enterprise Linux and next-generation
Power Systems with both little endian and big
endian applications.
• Fast time to value, more solutions: Accelerate
innovation by removing application portability
barriers. Take advantage of the vast Red Hat
ecosystem of certified applications originally
developed for x86 architecture.

Why little endian
support matters
• Big endian and little endian operating modes
allowed application developers to maximize
application performance by exploiting differences
in processor architectures.
• Proprietary-minded vendors also capitalized on the
reduced application portability: applications were
more tightly tied to speciﬁc platform architectures.
• The pressures of open computing forced
a change.
• Today, Power Systems can accommodate
both big endian and little endian applications
in one box.

Migrate to Power Systems without
software development.
Wait less. Innovate more.
It’s easy to make the move to Power
Systems. Why?
• Red Hat Enterprise Linux for Power Systems runs a
wide array of Linux solutions.
— IBM adds value by offering integrated solutions
that draw on deep industry expertise and a
broad ecosystem of partners and alliances.
• Red Hat Enterprise Linux 7.1 introduces support for
both big endian and little endian modes on IBM
POWER8 processors.
— Migrate existing commodity applications
and capitalize on the advantages of IBM
Power Systems—with little to no additional
development work.
An enterprise-grade solution
Run Red Hat Enterprise Linux 7.1 on Power
Systems for a truly enterprise-grade solution.
Enterprise applications + enterprise Linux +
robust, open enterprise server architecture

Power Systems with POWER8 technology offers:
• Up to eight threads per core
• Large internal bandwidth
• Large caches
The result: Power Systems delivers industry-
leading application performance on a variety
of key enterprise workloads, including big
data, analytics and business intelligence.
Designed for big data
“Big data work requires lots of processors,
cores and threads to spread out the
queries for parallel analysis. These
workloads also need large cache and
memory spaces to provide the best
context for business insights. And whether
it be in the cloud or on-premises, network
bandwidth with lower latency is critical
to these new demands.”
—Doug Balog, General Manager, IBM Power Systems

Built-in capabilities help Power Systems
provide strong reliability for mission-
critical applications:
• Redundant bits in the cache area
• Innovative error-correcting code (ECC) memory algorithm
• Self-diagnosis during runtime
• Automatic reconfiguration processes
Strong reliability
for mission-critical
applications

• Low acquisition costs: Cut the costs
of new investments.
• More users, more transactions per
core: Achieve faster time to value
and maximize investments with
high hardware utilization.
• Reduced operational costs: Control
power, cooling, administration and
maintenance expenses.
• Scalability: Scale to accommodate
new workloads and build new
cloud environments while keeping
expenses in check.

IBM together with Red Hat continues
to build on this open server platform:
• IBM has a strong road map for ongoing Power
Systems improvements.
• Innovation drives greater performance per watt
through virtualization, advances in memory and
I/O acceleration.
• IBM is also a founding member of the OpenPOWER
Foundation—a consortium dedicated to
facilitating collaborative innovation on the
IBM POWER® platform.
