pSeries Operating Systems
The Linux operating system (OS) has earned a
reputation for flexibility and cost effectiveness, resulting in rapid growth of
the number of supported applications—both custom-built and ISV packages. More
and more companies are turning to Linux applications—and more of these
applications are becoming integral to their success. IBM offers an
enterprise-class Linux on POWER™ server solution for business-critical
applications by combining a Linux OS from a Linux distributor with an IBM System
p™ server or BladeCenter® blade server.
IBM Power Architecture™ servers have a well-earned reputation for high
performance and superior RAS (reliability, availability, serviceability)
features, a reputation that is proven by IBM System p server and BladeCenter
blade leadership in the UNIX® and Linux marketplaces. The foundation is advanced
IBM POWER5+™, POWER6™ and PowerPC® processor technology. With these advanced
64-bit chips, IBM servers lead challengers in many key benchmarks1. The Linux on
POWER operating system can take advantage of this high-performance architecture.
In addition, IBM has enabled a wide range of RAS features on these servers for
the Linux operating system, offering a platform to keep business-critical
applications up and running. To complete the solution, these servers offer the
extraordinary efficiency available with advanced virtualization technologies.
System p and BladeCenter platforms offer options for logical partitioning and
available IBM Micro-Partitioning™ technologies, allowing the allocation of
system resources to match the needs of a business.
IBM is working with Red Hat, Inc., Novell SUSE Linux and ASIANUX (in China,
Japan and Korea) as Linux Distribution Companies to deliver tested Linux
operating systems supporting System p and BladeCenter platforms. IBM provides
the ability to order a full distribution of Red Hat Enterprise Linux (RHEL)
Versions 4 or 5 or SUSE Linux Enterprise Server (SLES) 9 or 10 in conjunction
with new System p and BladeCenter server purchases.2 By bringing these servers
together with the Linux operating system, you get the best of both worlds: the
enterprise-class capabilities of the System p or BladeCenter platforms and the
flexibility and cost advantages of the Linux OS.
