The old Red Hat Linux is called Red Hat Linux Red Hat Enterprise Linux is available as ES (most servers), AS (for processors or more), WS (workstation) > I guess SMP is the only reason > to make it different. Is the EL version smp enabled ? > And is the workstation version smp disabled ? All versions of Red Hat Linux, Red hat Enterprise Linux, and Fedora include SMP. The only thing is if you want to buy *support* for, say, four processors or more, you'll need to get AS (if you want to get that support from Red Hat). > And is the workstation version smp disabled ? Nope. They'll all happily work on however many processors on any of seven official architectures (plus a few more unoffical ones). >Any other features > that may be in EL kernel but not in WS ? Yup. Large databases like Oracle need a large amount of not only free RAM, but contiguous free RAM. The kernel shipped in Red Hat Enterprise Linux is tuned for this purpose, taking the maximum amount of contiguous memory from around 1.3GB to 3GB on a 4GB x86 machine. There's a bunch of other performance bits and pieces too, but that's one of the main ones. If you want RHEL Linux, you can purchase it. If you're just interested in the kernel, you can download the kernel-source package from Red Hat's FTP site, rebuild it, and install it on your distro of choice.
