purchase vs download, SMP and NUMA
We used a set of SuSE products for x86-64 (beginning from SLES8 and then SuSE professional 9). I have few questions about new versions. 1) Currently there are SuSE 10.x instead of SuSE professional 9.x. What is the difference between free downloadable version of 10.x (for example from opensuse.org) and SuSE 10.x DVD media I may purchase from any reseller ? 2) There is SMP kernels in the frames of SuSE 10.x. What is the restriction for number of cores per server (i.e. will it support 8 cores in dual-socket 4-cores Opteron in the next year ?) 3) In old SuSE versions there was special NUMA kernel in addition to SMP. What is about support of NUMA mode in modern kernels from 10.x ? Yours Mikhail Kuzminsky

You get a printed manual, installation support and IIRC some non OSS apps with the purchased version.

We didn't put anything in there to prohibit it at least. So it should work. We'll know for sure once these CPUs are available. Fixes however will be put in the 10.2 codestream rather than 10.1.

The separate kernel is not needed anymore. BB
