Sun Solaris, OpenSolaris "Hot on the heals of Oracle's revamp of Solaris support, the licensing agreement for free downloads of Solaris 10 have changed. Here is the bit in question: "...Please remember, your right to use Solaris acquired as a download is limited to a trial of 90 days, unless you acquire a service contract for the downloaded Software". So far the OpenSolaris license has not changed, it's still CDDL."

SPARC vs x86

Truth to be told, the new x86 cpus, AMD and Intel are actually among the fastest in the world.

Four AMD 8-core Magny Cour at 2.3 GHz gives almost 600 specint_2006. If you instead choose 12 core Magny Cour, in best case you will get 50% more performance, that is 900 specint_2006.

Four IBM POWER7 at 3.5GHz gives 1000 specint_2006. The IBM machine with 128GB RAM costs maybe 175.000 USD so you can probably buy 4-5 AMD servers for the same amount.

And the Nehalem-EX will probably be faster than AMDs CPUs.

Ordinary SPARC cpus has the same problem, x86 is faster than the SPARC cpus. However, the niche Niagara SPARC can be many times faster than the fastest x86 on certain work loads (multi threaded light work).

The problem is if you try to run many sockets and many cores with these new x86 CPUs. Linux and Windows does not scale good enough. But Solaris does.

This means that Oracle/Sun wins:
1) Solaris on many sockets Nehalem-EX will be the natural choice, and much cheaper than POWER7 machines, giving a similar performance for a fraction of the cost.
2) Solaris on Niagara will be good for multi threaded work loads, it will be several times faster than x86.

In either case, Solaris wins. No matter which workload you have, Solaris will run it for you. Either on cheap fast x86 or on Niagara.
