Oracle and SUN "Several of the concerns about Oracle's acquisition of Sun have revolved around how Unix technologies led by Sun would continue under the new ownership. As it turns out, Solaris users might not have much to worry about, as Oracle executives on Wednesday affirmed their commitment to preserving the efforts. In the case of Solaris, Oracle had already been a big supporter of the rival Linux operating system. Oracle has its own Enterprise Linux offering, based on Red Hat Enterprise Linux. For Oracle CEO Larry Ellison, the idea that Linux and Solaris are mutually exclusive is a false choice."

Laggard AIX has something truly "enterprise" that trendy Solaris hasn't: good virtualization.


I suppose you are talking about capabilities of System p hardware, not AIX. Btw SPARC machines have virtualization capabilities too.

SUN changed their virtualization plans every year!


Citation needed.

Containers/Zones and LDOMs are good but can't compete with AIX's LPARs (or VMware ESX or even Xen).


First of all, you are totally confusing hardware virtualization and OS-virtualization. Technologies you named are different tools for different purposes. Second, with zones you can have hundreds of virtual environments on single server, how many can you have with VMWare, LPARs or Xen? Third, Solaris does run on Xen as dom0 and domU.

You have to do black magic to run RHEL or Solaris 8/9 using "Branded Zones"... that's not "high end", that's not "Enterprise"... that's a complete joke.


That's not a joke, that's how OS-virtualization works.

ZFS and Dtrace are amazing, I love 'em, but They're pretty new technologies! You don't have ZFS in every Solaris box out there! (in fact VxVM and SVM are much more common).


What? Solaris 9 was EOLd long time ago, and there is already eighth update of Solaris 10 (which includes ZFS) available. You expect ZFS to be backported or what?

AIX have LVM since 1991 or so, and Linux since 1998.


What's yor point? Solaris has Disksuite a VxVM for very very long time. (I'm not going to google for exact time.) Btw. Linux's LVM is practically useless.

Solaris is really good, but It isn't more "high end" than RHEL, AIX or any other Enterprise *nix. That's a complete marketing bullshit.


Linux on servers is x86 (== low end) OS, that's all. Term "enterprise Linux" is an oxymoron and is not in the same category as Solaris and AIX.

All of your points are very good and it's true that most of the virtualization in AIX is hardware based but just like Zones, AIX has OS virtuailzation as well. It's called WPAR (as in work partition). In the end though, both platforms rely mostly on hardware when it comes to true virtualization with POWER having the added advantage of hardware virtualization support built in from the low end all the way up and having inherited all the tech from the mainframe.

The two things that AIX is missing are obviously DTRACE and ZFS, the latter of which anybody would have to admit is a trully superb filesystem, but if I wanted serious hardware virtualization and had the choice, I'd go for AIX any day. The ability to add and extract servers from a virtualized pool, live migrate from one server to another and do all this through an extremely simple to use web interface without needing to resort to the command line puts pretty much anything Sun has to shame, for the moment.

Addendum: I wouldn't go so far as to call Enterprise Linux an oxymoron. I've installed SLES on POWER for a TSM backup server and Linux uses the inherited low downtime capabilities of the POWER platform just as well as AIX does. Thanks to the tools IBM have developed for LoP (Linux on POWER), it is just as totally trivial to swap out CPUs, memory and expansion cards as it is using AIX. If the kernel couldn't handle hot-swapping, then I'd think you'd have a point, but that is demonstrably not the case.

I agree that AIX+POWER probably has better virtualization capabilities than Solaris+SPARC. After all IBM has all the mainframe know-how. I wouldn't say that Sun should be ashamed, as most of things which you outlined can be done with other tools, like Sun Cluster (as for live migration).

I'm still waiting for Linus to acknowledge the need for stable kernel API and ABI. Until that day, I can't take Linux seriously, sorry.
