AIX7 is coming!
Just a quick look at the features for AIX7 - which is coming soon. Take a look at AIX7 Preview for an official statement. The two major items for me are 1) Scaling to 256 cores (or CPUs as I have called them for 25 years) Power systems always had lower CPU counts than the competition particularly in the high end machines due to the faster speed of the processor and this benefits batch (single threaded) work, software costs (lower CPU numbers) and is easier for scaling up but now a truly massive POWER7 machine is near and AIX7 is the OS to run...

What is the savings of using WPARs over LPARs?
I was just asked this question by customer and it got me thinking, Items I would include: WPAR takes seconds to create and LPARs minutes LPARs need setting VIOS LV or LUNs but WPARs add simpler NFS mount points, or can just use Global AIX diskspace options LPAR needs 512 to 1GB to boot AIX and a WPAR takes just ~60 MB (yes sixty megabytes) You can share application code say 1 GB in each and every LPAR (40 LPAR = 40 GB) or just one shared read-only copy for all WPARs 40 WPAR = 1 GB).This saves man-power in maintenance, disk space AND memory (if...

AIX7 Open Beta - download yourself a copy today
The AIX 7 Open Beta is available now - this gives you access to the version to be released later this year. Find the summary in a earlier AIXpert blog and then the details at the new AIX7 Open Beta website. I have downloaded the image at just 2.4 GB (watch out for your 1GB default ulimit) for the entire AIX OS and have it running fine. I installed via my VIOS based virtual optical drive. Also included are access to new compilers versions, the AIX7 documentation and support via a Forum.

Things have moved on since AIX 5.2
We needed to install AIX 5.2 in order to create a mksysb for AIX 7 Versioned WPAR testing - this allows you to run AIX 5.2 in a WPAR. First we had endless problems locating media but our Computer Room Manager Mike turned up trumps in the end - he keeps everything and regularly saves the day. So we loaded all 7 CDROMs on to our VIOS to add them to the virtual Optical Library. Second, we booted from the CDROM only to with an immediate halt with a warning the AIX 5.2 can't run in a Shared CPU LPAR - doh! we should have realised that one. It was a... [More]

Step change in POWER7 performance
I just noticed the rPerfs (relative performance numbers) for the four new Entry Level systems (Power 710/720/730/740) and the High End Power 795 are available in the updated "Power Systems Facts and Features" document on the IBM website. My notes: The Entry Level machines are now 16 core/CPU/way (delete as you like to call them). That is a serious machine for the bottom end 2U rack server and it has all the POWER7 virtualisation features built in. These humble machines have the roughly the same performance as the mid-range previous... [More]

Announcing AIX7 & download from 10th Sept 2010 |
Versioned WPAR runs AIX 5.2 on POWER7
With AIX 7 and POWER7, you now have the option to run the old withdrawn AIX version 5.2 within a
WPAR with this new offering - AIX 5.3 Workload Partitions for AIX 7, version 1.1 This will run the same AIX 5.2 OS, same middle-ware and same application
but on right-up-to-date hardware and OS. Then you can remove the old
POWER4 (or older hardware) to: Reduce electricity & heat, Free up floor
or rack space, Reduce hardware maintenance or if you don't have it, reduce your risks, Plus either a
performance boost due to POWER7 or reduced... [More]

Ten Smarter Technologies - coming your way
Hi, I am preparing for a Power Systems Technical University in Las Vegas, USA and Lyon, France in October. I have a session with the title below and I am seeking feedback from technology guru's like yourselves. Which four of the below ten technologies do you think are "most likely to be normal in five years time"? Please comment on this AIXpert (see "Add a Comment" below) with your four top technologies. I will post the overall results as a graph in roughly two weeks time. Below here there should be a large image of the ten... [More]

AIX 5.2 Versioned WPAR - Ideas for a demo, please
We have blogged on this really cool AIX 7 feature in the past - but here is my problem: Once I install the AIX 5.2 mksysb image in to the Workload Partition running on AIX7 it all works fine but ... then what can I show an audience to show off "AIX 5.2 running on top of AIX 7": I need a simple application that only runs on AIX 5.2 . Something simple enough that it does not take hours to install and hopefully that it is something visually interesting to see. I am told we can run Oracle 8 now including the kernel extension but its not... [More]

Prague Technical University - it is not all work
This picture was taken by Shawn Mullen - Security Architect for AIX and cool speaker at the event too. It was taken outside of the Gala Dinner on the Wednesday evening - where we had good food and "interesting" Czech musical entertainment at the beautiful historic Zofin Palace on an island in the main river. From left to right are some of the top speakers at the conference: Ignoring the waiter with the excellent champagne!
