AIX6 open beta
Thursday, May 24. 2007
AIX has itīs own beta programm. Itīs open. But no OpenAIX so far. But there is no real kicker in the new version so far: Workload Partitions ? Looks like Solaris Zones. RBAC is in Solaris since Solaris 8. RBAC in LDAP? For years now. Caching of name server requests. This is pretty much state of the art in all operating systems since .... since the last century. Probevue ... there is not much information about it. So i canīt really say anything about it. Looks like idea similar to dtrace.
The more interesting point is: I strongly believe, that IBM is in fear of Solaris. For a long time AIX was something like an unwanted child. Linux was the way to go. Commercial Unix systems lost their appeal in comparision to Linux. But then Sun revived Solaris with Version 10. And now there is a technological advanced enterprise class Unix. It left IBM without a competitive operating system for their high-end-server franchise. AIX 6 looks like a reaction to this. But in most fields Sun has years of advantages. When AIX6 comes to market, even the newest anticipated features in Solaris are in their third and fourth iteration.

I can only see one real advantage in POWER6 and AIX 6, namely the live migraton of LPARs.
Of course this will be possible with Sun LDOMs around next year.
One feature with POWER6 I 've heard rumours about but haven't found any sources, was memory overcommitment for LPARs. Unfortunatly I don't have any more details...

I think you're seriously understating the abilities and performance of AIX in general and AIX 6 in particular.
You compare the Workload Partitions to Solaris Zones, but don't mention that AIX 5 has had hypervisor based virtualisation for years now on power5 equipment, along with Workload Management at the operating system layer. The new partitions just let you do things a third way if you so choose, after all flexibility is good.
You criticise the TPC-C benchmark as well in another post, the cynic in me wonders if that's because Sun don't have a system in the top 10, it's a benchmark dominated by HP and IBM. If Sun could get a machine in that top 10, I have absolutely no doubt they would publish the results.
I thought the high-profile feature of Solaris 10 was ZFS, a purely catchup feature to AIX and even Linux despite the marketing hype, as before ZFS Solaris relied on Veritas to give it an enterprise class Volume manager and filesystem, something AIX has had built-in since the AIX4 days.
Solaris is an excellent Unix operating system, just as AIX is, and HP-UX are, all 3 are more than capable of running pretty much any task you want, though they have different ways of doing it. To me the main differentiator between the 3 over the last couple of years has been hardware, Sun have gone with the "many-core" concept, which works very well under some circumstances, HP went with Itanium which looks to have been a horrible mistake, and IBM have Power5+ and now Power6, which is in raw performance terms, the fastest chip you can get right now.
If you need a machine to give you very high performance without having to buy 128 cores worth of Oracle CPU licences, your choice at the moment is obvious.
