Red Hat has launched Red Hat Enterprise Linux (RHEL) version 4 at this week's Linuxworld conference, and has aimed it squarely against Sun’s Solaris operating system, which is now going open source.

"Red Hat Enterprise Linux version 4 proves that Linux solutions can effectively eliminate the need for Solaris in the enterprise," claimed Red Hat.
Paul Cormier, Red Hat executive vice-president of engineering, said RHEL in 2002, marked the entrance of Linux in the enterprise. He claimed the second version one year later put it on par with Unix in terms of reliability and ahead in terms of value.
RHEL version 4, he said, "has the performance, scalability, security, and application portfolio needed to make Linux the sensible choice for every enterprise deployment".
Version 4 supports the latest Linux 2.6 kernel and can support both 32- and 64-bit computing. The system is also bundled with the increasingly popular open-source Firefox browser from the Mozilla Foundation.
Dell, Hitachi, EMC, HP, IBM and Intel have all said that they support RHEL’s introduction and intend to support the operating system in their products.
