Red Hat, Inc. (NYSE: RHT), the world’s leading provider of open source

solutions, today announced the availability of the fifth update to the Red Hat

Enterprise Linux 5 platform, Red Hat Enterprise Linux 5.5. Adding features

designed to operate across physical, virtual and cloud deployments, the update

offers enhanced virtualization and interoperability capabilities combined with

support for important new hardware platforms. As with all Red Hat updates,

application compatibility and certification with the Red Hat Enterprise Linux 5

platform is fully maintained, meaning the broad portfolio of certified

applications for Red Hat Enterprise Linux applies to the new update. Red Hat

Enterprise Linux 5.5 is available to subscribing customers via Red Hat Network

today.

 

In addition to overall platform enhancements and bug fixes, this update provides

support for new platforms being delivered by several Red Hat partners, including

AMD, Dell, HP, IBM and Intel. Newly supported platforms include Intel Nehalem

EX, AMD Opteron (TM) 6000 Series (formerly codenamed “Magny Cours”) and IBM

Power 7. This allows Red Hat customers to take advantage of some of the

industry’s most powerful new servers.

 

“Red Hat Enterprise Linux and AMD platforms together provide our customers with

compelling datacenter reliability and flexibility,” said Margaret Lewis,

director, Software Solutions Marketing at AMD (NYSE: AMD). “The latest

technology enhancements in Red Hat Enterprise Linux 5.5 combined with our new 8-

and 12-Core AMD Opteron 6000 Series platforms offer customers improved

performance while still maintaining low power consumption, helping to lower

total cost of ownership.”

 

“Through the combination of Dell PowerEdge servers and Red Hat Enterprise Linux,

customers are offered a scalable, high-performance, affordable solution,” said

Sally Stevens, vice president of Enterprise Platform Marketing at Dell. “New

technology advancements in Red Hat Enterprise Linux 5.5, coupled with Dell’s

11th generation of servers, give users a robust platform for running their

mission-critical applications on an industry-standard x86 architecture.”

 

“Rising operational costs are driving clients to seek higher performance

technology solutions at a lower cost,” said Scott Farrand, vice president,

Infrastructure Software & Blades at HP. “The combination of Red Hat Enterprise

Linux 5.5 on energy-efficient HP ProLiant servers and HP BladeSystem with

Virtual Connect Flex-10 technology provides clients a high-performance, low-cost

platform to run demanding Linux workloads in virtualized environments.”

 

“IBM’s new eX5 hardware combined with Red Hat Enterprise Linux 5.5 brings new

levels of flexibility and scalability to the enterprise, particularly with the

additional memory capabilities of the new platform,” said Jean Staten Healy,

head of IBM’s Linux strategy. “eX5 together with Red Hat Enterprise Linux and

Red Hat Enterprise Virtualization provide a powerful technology foundation for

today’s mission-critical infrastructures.”

 

“With today’s delivery of new technologies from both Red Hat and Intel, we are

continuing to help define the datacenter of the future,” said Doug Fisher, vice

president of the Software and Services Group and general manager of the Systems

Software Division at Intel Corporation. “The combination of Red Hat Enterprise

Linux and the Intel Xeon processor 7500 and 5600 series delivers powerful

performance, energy efficiency, scalability and reliability across physical and

virtual systems that brings new opportunities for our joint customers.”

 

In the fourth update to the Red Hat Enterprise Linux 5 platform, delivered in

September 2009, Red Hat introduced the Kernel-based Virtual Machine (KVM)

hypervisor alongside the Xen hypervisor. Today’s Red Hat Enterprise Linux 5.5

update provides a number of virtualization enhancements. Support for the large

memory systems of new servers allows a larger number of virtual machines to be

deployed on each physical server. With greater guest density customers have an

opportunity to achieve higher levels of consolidation and reduce costs. Huge

page support is now automatic and extended to virtual guests, improving the

performance of memory-intensive applications. Support for Single Root I/O

Virtualization (SR-IOV) offers virtual guests an improved ability to share PCI

hardware resources and more efficient access I/O devices. As a result, Red Hat

Enterprise Linux is one of the first operating systems designed to be capable of

hosting a virtual guest that can saturate a 10 Gigabit Ethernet. Further I/O

optimizations, which enable easier device reassignment, can help improve

flexibility when migrating virtual guests across physical systems. In

combination, these enhancements aim to allow large-scale, I/O bound, enterprise

applications to be readily virtualized.

 

Red Hat Enterprise Linux 5.5 also offers Microsoft Windows 7 interoperability

enhancements and extends Active Directory integration, allowing improved user

and group mapping, while simplifying filesystem management across platforms.

 

“We believe that Red Hat Enterprise Linux continues to drive the evolution of

the operating platform forward with new technology that delivers performance,

reliability, scalability and affordability results for our customers,” said Tim

Burke, vice president, Engineering, Platform Engineering at Red Hat. “Red Hat

Enterprise Linux provides a powerful foundation for physical, virtual and cloud

deployments, and for many, continues to be the platform of choice for their most

demanding mission-critical workloads.”
