IBM and Red Hat developers at the Linux labs have collaborated to integrate new technologies in the Linux kernel that will help customers improve efficiency and gain a competitive edge in their industries.
Developers at IBM's Linux Technology Center, which has about 600 engineers in 40 locations worldwide, collaborated with Red Hat's Engineering team to integrate improved virtualisation features, security enhancements, and "Real-Time Linux" capabilities into the Linux kernel.
New virtualisation and security capabilities in the Linux kernel will also be available in the new release of Red Hat Enterprise Linux 5. "Real-Time Linux" technologies are currently being incorporated into the kernel and will be extended to IBM and Red Hat customers in a future offering.
The companies announced IBM is currently testing and certifying RHEL 5 across all of its standards-based middleware and servers and that IBM also plans to provide services and support for RHEL 5 as well.
IBM and Red Hat cited these three key Linux development innovations:
Xen virtualization optimises IT environments
IBM, Red Hat and the open community have now integrated open source Xen virtualisation software with the Linux kernel in addition to hardening the Xen hypervisor. Xen is open source virtualisation software that helps customers increase server utilisation and more efficiently manage Linux-based IT systems. The technologies will be incorporated into Red Hat Enterprise Linux 5 and supported by IBM's Virtualization portfolio of products running on Intel and Opteron processor-based servers and IBM BladeCenter systems.
Security-enhanced Linux for better data protection
Addressing customer demand for features that provide greater data protection, IBM and Red Hat developers collaborated with the open source community to build Security-Enhanced Linux into Red Hat's core operating system to provide Multi-Level Security capabilities. These capabilities enable enterprise customers, particularly those in the government sector, to create a mandatory access control policy that allows information to be classified as top secret, secret, confidential and unclassified. This security underpinning of the Linux kernel compartmentalizes applications and services into distinct security domains, providing a highly secure platform for applications or data for all types of customers. After testing and certification, these features will be available in RHEL 5, and supported by IBM software and systems.
"Real-Time Linux" application development platform
IBM and Red Hat are collaborating to deliver a new "Real-Time Linux" application development and deployment platform providing customers the ability to run systems that can perform at greater processing rates with high levels of reliability. The new platform includes IBM WebSphere Real Time, a real-time J2SE Java Virtual Machine, with a real-time version of Red Hat Enterprise Linux 5 running on IBM System x and BladeCenter AMD and Intel-based servers. This new computing infrastructure also provides a broad community of Java programmers the ability to develop applications that can execute and provide predictable to millisecond granularity execution times.
