system with 1 Terabyte of memory, which previously may
have consumed a full rack, can now be configured in a
single 4U form factor, and can deliver improved perfor-
mance at a much lower cost. Red Hat Enterprise Linux also
includes low-level kernel optimizations aimed at providing
full application performance while in the lowest possible
power states.
Red Hat Enterprise Linux continues to regularly set new
standards in the industry on workload benchmarks as
diverse as ERP, Business Intelligence, TPC, and SPEC. See
why Red Hat solutions are preferred for getting the most
out of hardware and applications. Visit spec.org, tpc.org

Virtualization. Red Hat is a driving force behind the
development of open source virtualization technology.
Red Hat's approach to virtualization is easy to adopt,
because it is delivered as an integral part of the Red Hat
Enterprise Linux platform. The original release of Red Hat
Enterprise Linux 5 in early 2007 incorporated an enter-
prise-hardened implementation of the Xen-based hyper-
visor technology. With Red Hat Enterprise Linux 5.4,
Red Hat also introduced the newest virtualization technol-
ogy, Kernel-based Virtual Machine (KVM), which is inte-
grated into the Linux kernel and leverages the newest
hardware virtualization capabilities provided by Intel
and AMD processor platforms. The modular design of
Red Hat Enterprise Linux allows customers to choose when
and where to use virtualization within the context of their
deployment. For additional flexibility, customers can deploy
both Red Hat Enterprise Linux and Microsoft® Windows®
as fully supported guests. Red Hat Enterprise Linux sup-
ports multiple virtualization use cases, from hardware
abstraction for existing software stacks, to datacenter
consolidation, to virtualized clusters and private clouds.
Security. Security for Red Hat Enterprise Linux begins
with a core feature known as Security-Enhanced Linux
(SELinux). Co-developed with the U.S. Government's
National Security Agency, SELinux provides for a strong
and flexible MAC framework to enforce role-based access
control and multi-level security. In addition to SELinux,
Red Hat Enterprise Linux includes system firewalls, audit
capabilities, and system package and file integrity verifica-
tion tools for a complete security architecture that covers
deployment models ranging from Internet-facing servers to
trusted computers. Backing up the core technology is the

Red Hat Security Response Team, recognized as industry
leaders for addressing security vulnerabilities. In summary,
Red Hat Enterprise Linux provides an unmatched security
environment for customers and their applications. View
redhat.com/security for more detail.
High availability. An integrated high-availability clustering
capability allows customers to easily deploy and manage
high-availability applications. Scaling from two to 16 nodes,
application high availability can be managed through pol-
icy definitions. Integrated application failover agents are
included for SAP, Sybase, and Oracle, and customers may
customize the Red Hat-supplied resource agents for other
applications.
Manageability. Deploying and managing a Red Hat
Enterprise Linux environment is enabled by Red Hat
Network (RHN). RHN is a highly scalable management
platform for provisioning, updating, and controlling
Red Hat Enterprise Linux environments. RHN and its on-
premise version, RHN Satellite, provide organizations and
their administrators with tools to lower their per-system
deployment and management costs by automating and
centralizing routine tasks and creating a consistent envi-
ronment, resulting in less unexpected downtime due to
human error.

Storage. Red Hat Enterprise Linux includes sophisticated
disk and logical volume management capabilities that
support numerous enterprise features, including high-
resiliency via multi-pathed storage devices, the ability to
combine physical devices into logical units, RAID capabili-
ties, online device addition, dynamic volume expansion,
and online filesystem growth. All storage management
functions are available online, without impacting applica-
tion availability.
