In the News In a move that would certainly shake up the computer industry quite a bit, IBM is reportedly in talks with Sun Microsystems about the possibility of IBM acquiring Sun. Sun is going through hard times at the moment, and has been actively looking for someone to be acquired by.

I think I even overestimated Linux. Maybe 32 cores max. But enlighten me, show me a link to x86 server with more than 32 (okay, maybe 48) cores.

I'm not entirely sure why you're talking about 'cores', but if it's actually SMP systems you're talking about (it can't be anything else) then I think you've been living in the dark ages somewhere. Either that or you believe Sun's marketing literature.

Trust me, it's been done and people are running stuff with an awful lot more than 32 'cores' in them. Have been for years. To post links would be fruitless and would merely insult your ability to use Google. If that's beyond you however then SGI have been doing the really big stuff, and that's with kit with >= 1024 CPUs in them. They're enormous:

Certainly at the time that that thread was posted Solaris had never ran on anything like a 1024 CPU system. To top it off, Solaris doesn't do RCU locking either:

Linux not scalable? Solaris more scalable? More 'solid'? I Wouldn't call it FUD. It's just outright desperation, but hey, that's why Sun are in trouble.

I could tell you stories from experience how "unbrekable" Oracle Linux is on 8 core AMD server.

Dunno. There's umpteen people doing it, so maybe it's just you? I could tell you many stories about Solaris's exceptionally buggy drivers, many of them IDE drivers that Sun is only now finding out about by using ZFS as a debugging tool, how difficult it is to get software actually installed on Solaris and how it has had to be explained to Sun's consultants that no, we aren't going to make SPARC faster by recompiling our open source software in Forte.

However, if you chose Oracle Linux then you probably don't know what you're doing anyway so it's all academic really.
