General Unix Prior to the general availability of AIX 6, IBM intends to make a pre-release version of AIX 6 available in an open beta. "AIX is an open, standards-based UNIX operating system that provides the enterprise information technology infrastructure for thousands of clients around the world. IBM intends to take the next step in the evolution of the AIX operating system with the release of the AIX V6.1 OS."

RE[6]: Need more UNIX

Yes you are correct, Solaris has OS virtualization (zones, which is like BSD jails) and hardware partitioning. They are working on getting Xen working in a high quality way on Solaris X86, which would provide X86 virtualization support (for Linux, Windows, etc).

The thing with LPARS is it tied to the IBM hardware hyper visor. As far as I know it runs AIX and Linux, but not Windows (like Xen can). Benchmarks out their show Xen is actually very efficient, and close in many areas to native speed.

Solaris zones also support Linux binary compatibility. So you can run Linux applications right on the Solaris systems without recompile. So basically by using Solaris zones on X86 you can run Solaris applications and Linux applications in virtual zones. How is IBM's hardware solution that runs Linux and AIX tht much better. Does it justify spending that much more $ for their hardware hyper visor? I have used Solaris system with many zones running on them and I can say it is very efficent and very stable.

Why X86? If you have noticed recently even X86 is moving quickly. In the past you could say Intel/AMD sucked compared to Power6 and SPARC, but X86 is catching up quick. AMD64 chips and the Intel chips are nothing to laugh at. They are taking power requirements serious, they are adding virtual environment extensions, and multiple cores. X86 is getting to a point where it can be used efficiently in the Enterprise (unlike in the past).

I know in a previous post you said IT bought a bunch of Dells/HP and tried to run on that, and found out it was junk. I agree with you totally. But yesterdays X86 hardware is just not the same as today’s X86 hardware (like Suns AMD offerings, Dells DL's, HP Proliaents). They are compact, they have management cards built in, they have built in diagnostics, they have multiple cpus (with multiple cores), and the big one being they are power efficient. The huge problem companies saw with the past cheap X86 hardware was it broke a lot, and it used ALOT of power (like P4's). Today, and into the futures trend is a whole new direction for X86.

You use a generic term with Linux. Most serious businesses will use a supported Linux such as Red Hat, Novell SUSE, etc. Have you compared the cost of using Red Hat Enterprise vs Solaris X86, in terms of getting the software and service support? You will be surprised that Solaris X86 is very competitive on price. So I think Solaris X86 can compete very well with supported Linux's in the business market.

So I think Solaris being in the X86 is a VERY smart move, even in the medium to Enterprise business area.
