Red Hat delivered its latest major operating platform release, Red Hat Enterprise Linux 6, in November 2010, representing a new standard of flexibility, efficiency and control for customers’ commercial open source environments. The release included features applicable to all computing environments from physical to virtual to the cloud – with improvements in performance, scalability and reliability. The platform has been well-received by customers and we announced earlier this week that Red Hat Enterprise Linux 6 has already set a new standard in storage performance based on internal testing by Red Hat engineering.
Today, Red Hat Enterprise Linux 6 takes another step forward with the availability of the beta for the first update to the platform. The beta includes new features, bug fixes and support for new hardware from our key partners. We encourage our customers, partners and the community to install the beta and share your feedback on this latest update to Red Hat Enterprise Linux 6 with us.
