Features of 11i question

We are thinking of upgrading from 11.0 to 11i. I just began reading the features available on 11i and noticed that it can be segregated into seperate systems. Does this work only with certain hardware, ie. an Itganium based system? Is it possible to have one partition 11i and the other 11.0? I could be way off base but I thought I had read something about this.
Thanks
Any Ideas?

Correct.

Here's a overview of supported environments in virtual partitions.

Re: Features of 11i question

Hi Gerry,

What you are refering to is called partitioning. There are two methods to partition a server - hard partitions (npars) where the partitions are completely isolated from another, or virtual partitions (vpars) where the vpars are located within an npar. In this could npar could mean the full server complex.

Both partition options are only available on certain system (this is from memory) :

npars : rp7410, rp8400, Superdome
vpars : the above + rp5470 (and more)

I think npars is only available on those systems as it needs a server with more than one system bus.

You will be able to have partitions running different OS's but they will all be 11i or greater - 11.00 does not support this. Also you can run linux or Windows on different npars.

For full information please see the 11i page on the documentation server :

Re: Features of 11i question

Hi:

Release 11i is certainly the upgrade path to choose. Not only does 11.0 now have a "discontinuance" date, but 11i is much more feature-rich.

http://www.software.hp.com/RELEASES-MEDIA/history/slide2.html

11i supports both PA-RISC and Itanium although slightly different releases are needed:

HP-UX 11i version 1.0 (11.11) PA-RISC
HP-UX 11i version 1.6 (11.22) IPF

If I recall correctly, the to-be-announced HP-UX version 2 (HP-UX 11.23) will support both PA-RISC and IPF (Itanium).

Regards!

Re: Features of 11i question

HP 11i(11.11) runs on a wide array of hardware. Its more reliable.

If you wish, you can install 11.00 into another boot disk and boot off that.

Its not a really good idea though.

HP-UX 11i v2 has just been announced. It is supposed to be the unified OS that works both on PA-RISC and Itanium.

Re: Features of 11i question

Hi,

Release 11.23 has indeed just been announced :

http://www.hp.com/products1/unix/operating/choice/hpux_itanium.html

James & Steven, you were right to think that but its been changed I'm afraid, 11.23 is now an Itanium only release. I _think_ you could have Itanium and PA-RISC processors in a npartition capable system that supports both, i.e. a superdome.

There is another level to partitioning now, called rpars I believe. Basically this is defined as psets and the like, I think it means resource partitions. Not really relevant here but thought I'd add it.

Regards,

James.

Re: Features of 11i question

Just to complete the picture, the is HyperPlex - hard partitions with multiple nodes as the highest degree of separation.
Also HP-UX WLM (workload manager) is an automatic goal-based resource allocation via set SLOs.

Re: Features of 11i question

Hi James M.

Thanks for the link and the notation that 11.23 is Itanium-only. The "word" had been that 11iv2 was to be a coalescence...oh well.

Kudos to HP for the 60% more dynamically tunable kernel parameters. HPWorld 2001 had promised that and here's the proof.

Kudos too for the new ITS (Install Time Security)!

Warmest Regards!

Re: Features of 11i question

Hi James,

I think you can safely say the next release will be the convergence. Shouldn't be too long either.

The 11.23 has a lot of new stuff, _most_ of which is documented in the release notes (when they appear). A few of interest :

Unified Page/Buffer Cache
Posix compliant NFS ACLs
DLKM IO patching
10 Gig Ethernet Support
NO Kernel rebuilds - you just relink
Cell local memory - this can be tuned by SAs

Thats just a few off the top of my head. Expect the number of tunables to rapidly increase per release too. No more nflocks/dbc issues.....bliss! :-)

Cheers,

James.

Re: Features of 11i question

Hi

Nice thread.... I was under the impression that 11.3 will be the convergence for 11i PA-RISC & Itanium. I was told (no documents!!!) that this would be out early 2004. 11.2x is purely 11i fot Itanium.

The main reason for saying this is it seem the "market" is waiting for a common OS to before embracing Itanium. Anyway that is the impression I got
