Red Hat has released the fourth update to its Red Hat Enterprise
Linux 5 platform, Red Hat Enterprise Linux 5.4, which lays the
foundation for the Red Hat Enterprise Virtualization portfolio of
Red Hat Enterprise Linux 5.4 delivers expanded virtualization
capabilities with the inclusion of kernel-based virtual machine (KVM)
technology and Intel Virtualization Technology for Directed I/O (Intel
The new virtualization technology enables multiple virtual machines
in an Intel Xeon Processor 5500 Series-based platform to directly share
I/O devices. The new release also features improved I/O throughput and
the inclusion of additional tools for developers. Red Hat announced Red
Hat Enterprise Linux 5.4 at the Red Hat Summit 2009 in Chicago
on Sept. 2.
"Red Hat Enterprise Linux plays a significant role in Red Hat's
virtualization strategy, and the availability of Red Hat Enterprise
Linux 5.4 with the same virtualization technology base as Red Hat
Enterprise Virtualization today is a significant step in our delivery
of virtualization to the market," said Scott Crenshaw, vice president
of the Platform Business Unit at Red Hat. "The release also features
advances in performance, security and storage that span virtual and
physical environments. With this update release, Red Hat Enterprise
Linux aims to raise the bar once again, offering compelling software
technologies with impressive quality and reliability."
At the processor chipset level, the new Red Hat release includes
optimizations for Intel Xeon Processor 5500 Series platforms as well as
AMD Istanbul platforms. Network advancements include Generic Receive
Offload (GRO) that utilizes new processing components in advanced
network adapters to offload portions of the receive stack. Fibre
Channel over Ethernet (FCoE) performance enhancements and hardware
support are also included.
"Red Hat and Intel have long collaborated on technology advancements
to provide joint customers with reliable, high-performance and
cost-effective technology for their IT infrastructures that runs great
on Intel Xeon processor based platforms," said Doug Fisher, vice
president of the Intel Software and Service Group and general manager
of the company's System Software Division. "With today's update of the
Red Hat Enterprise Linux 5 operating platform, customers can take
advantage of the latest Intel processor and chipset advances in
physical and virtual environments. It's clear that the combination of
Intel Xeon Processor 5500 Series and Red Hat Enterprise Linux using
Intel VT-d and SR-IOV removes I/O virtualization bottlenecks to deliver
increased performance, efficiency and scalability with high performance
Meanwhile, new developer support includes enhancement to the
Systemtap performance monitoring toolset, including support for
profiling and monitoring C++ applications, as well as inclusion of a
large number of static kernel tracepoints to simplify performance
observation for the highest profile kernel subsystems, the company said.
"Red Hat Enterprise Linux 5.4 is certified on the Cisco Unified
Computing System," said David Lawler, vice president of the Product
Management, Server Access and Virtualization Business Group for Cisco.
"We continue to work closely with Red Hat to optimize both the Red Hat
Enterprise Linux and Red Hat Enterprise Virtualization platforms for
the scalable Cisco Unified Computing System to help enable our
customers to grow their virtualized environments, improve business
agility and provide coherent security and network policies."
IBM, HP and Dell also expressed support for the Red Hat Enterprise Linux 5.4 platform.
"IBM is pleased to support the availability of Red Hat Enterprise
Linux 5.4 with the inclusion of KVM technology for our clients," said
Daniel Frye, vice president, IBM Systems Software Development and Open
Systems Development Executive, in a statement. "KVM is an important
emerging open virtualization environment that IBM has contributed to
and will support."
"As companies continue down a path of server consolidation, there is
an increasing desire to derive cost savings from virtualization," said
Paul Miller, vice president of marketing for enterprise storage and
servers at HP, in a statement. "The combination of HP BladeSystem and
Red Hat Enterprise Linux, now with the performance of KVM
virtualization, provides customers with the low-cost, high-performance
combination customers demand, backed by two industry leaders."
"Red Hat and Dell continue to deliver joint solutions to reduce
complexity and lower operational costs for enterprises," said Judy
Chavis, director of business development in Dell's Enterprise Product
Group. "With today's delivery of the foundation of Red Hat Enterprise
Virtualization with Red Hat Enterprise Linux 5.4, certified with Dell
PowerEdge servers, joint Red Hat and Dell customers are offered
expanded scalability and performance, as well as the next generation of
