I can give you the most accurate info on OpenBSD. SMP Support for AMD64 and i386 has been available since 3.6, 3.7 is the current release, 3.8 comes out the first of November, although Austin over at openBSD has told me he that has already shipped me my order. So I should have 11 copies arriving soon. I digress, anyway. I have it running on a dual processor Opteron and it worked out of the box.
As far as FreeBSD goes, after FreeBSD released the framework for SMP and threading under FreeBSD 5, there was a conflict between the developers, several developers felt that the SMP and threading model used by FreeBSD 5.x would lead to crap performance, so FreeBSD Forked. Matt Dillion created Dragonfly BSD which continues to use the 4.11 framework but uses Light Weight kernel Threading and his implementation of SMP. I don't follow NetBSD, so I have no idea how their SMP implementation is going at the moment. MaxOS X also supports SMP, which is based on Darwin - which is the mach kernel with a 4.4 BSD wrapper. As far as hard drive and storage scaling, UFS is limited to two Tb, in 2003 UFS 2 was released which allowed storage to a much greater capacity. In my humble opinion I think that SMP is still pretty young in the BSD community. However clustering is old hat. daN -- _____________________________________________________________ " They that can give up liberty to obtain a little temporary safety deserve neither liberty nor safety.
