The idea is to provide the "cook book" information to get your started with these new interesting technologies and to answer some basic questions:

  • What is it about?
  • How do I get started?
  • What are a few typical first good uses I could start with?
  • How easy is it to use?
  • How could this save me time or money?
  • Where can I get more information?

Topics include:

  • POWER6 and POWER7 features
  • AIX 6 and AIX 7
  • Systems Director (ISD) for AIX
  • Integrated Virtualisation manager (IVM)
  • Back to POWER Basics for people new to this Virtualisation environment
  • PowerHA SystemsMirror
  • Other "cool or interesting" stuff

We hope you find these movies interesting and let you make a flying start. Currently, the movies add up to 29.1 hours of free education on hot topics

This new generation offers improved price performance. Then there is the new Power 750/760 - a totally new box using some Power 770 parts and offering up to 48 POWER7+ CPU cores, 2 TB of memory, Blind swap PCI adapters, and even the normally high end Capacity Upgrade on Demand for later Permanent activation of CPU cores. We have been testing the hardware and software for three months before the announcement and are very impressed with the performance and features like DPO to unscramble your LPARs for better CPU and memory affinity.


PowerSC - for Extra Power server Security and Compliance

This is new product is a collection of different tools for different security purposes. Currently, there is Trusted Firewall (short-cut), Trusted Logging (audit, syslog and AIX errpt log), Trusted Boot (anti-rootkit), Trusted SC for rolling out aixpert and ARTEX security and performance setting XML profiles can checking compliance, Trusted Patch to check all virtual machines on a VLAN have a minimum AIX level, Trusted Surveyor to document the virtual machines on a VLAN across the whole estate.

  1. PowerSC Trusted Firewall (short-cut) Runtime:18.5 minutes Movie:79 YouTube

    This cool new feature allows you to avoid using external firewall devices when communicating between LPARs on the same machine. This will speed up performance by avoiding many network hops, reduce external network traffic loads and reduce the bandwidth requirements to those external firewalls.For more information check the new PowerSC Wiki page.
  2. PowerSC Trusted Logging on YouTube only Runtime:27 minutes Movie:127

    On Power Systems and the virtual machines (LPAR) it is important to get the audit, system and error logs off the VM to protect against hackers/system crackers that break in. Following their work they would likely remove, edit the logs to hid what they were doing or even trash the disk. With the logs elsewhere you can do postmortem analysis of what happened and how to protect yourself. Trusted Logging does this over a vSCSI interface to the VIOS in a simple and clean way and even allows for Dual VIOS and Live Partition Mobility..For more information check the new PowerSC Wiki page.
  3. PowerSC Trusted Boot (Root-kit protection) on YouTube only Runtime:21 minutes Movie:128

    Trusted Boot is part of PowerSC (Security and Compliance for System Systems) that ensures no one or no thing has been fiddling with your LPAR setup, boot loader or boot images so you can have confidence you are in control of your AIX operating System..For more information check the new PowerSC Wiki page.

  3. Active Memory Sharing Regular Paging - Runtime:19 minutes Movie:58 YouTube

    Active Memory Sharing requires you to understand regular UNIX/AIX virtual memory paging before you start. If you don't understand paging then you are not going to understand AMS. Cover are 1) why do virtual memory? and 2) how the OS paging in and pages out memory to the paging space disks.
  4. Active Memory Sharing Concepts - Runtime:16 minutes Movie:59 YouTube

    Here the concepts of AMS are covered including very briefly the components, the various AMS modes of working to handle various cases which are 1) it all fits, 2) LPARs can co-operate over sharing memory and 3) when that is not enough and AMD has to force pages out.
  5. Active Memory Sharing Setup - Runtime:16 minutes Movie:60 YouTube

    Enough of the theory, this movie covers how to setup the Shared Memory Pool, the backing paging space on the Virtual I/O Server and then setup a Logical Partition (LPAR) to use AMS. It is very simple to setup. We convert a LPAR to AMS, start the LPAR and show how to confirm its using shared memory.
  6. Active Memory Sharing Simple Monitoring - Runtime:11 minutes Movie:61 YouTube

    In this movie we show "topas -C" and "vmstat -h 2" monitoring the simple AMS setup from the previous movie. We see at the whole machine level (with topas -C) the current LPARs use of memory. Both the LPARs using the shared memory pool and dedicated memory LPARs. Then AMS LPARs making room (loaning memory) for a newly starting Logical Partition that needs memory from the shared pool. Then a busy LPAR which is grabbing more memory pages due to high memory demand program takes more memory from the other LPARs. Finally, we watch at the LPAR level (with vmstat -h), it giving up memory for another high memory demand LPAR.
  7. HMC GUI for VIOS commands - Runtime:24 minutes Movie:63 YouTube

    With the May 2009 Hardware Management Console and Virtual I/O Server versions: the HMC can directly setup virtual disks, VIOS networks, Shared Ethernet Adapter, create extra virtual network switches, move physical optical between logical partitions, create and manage the media library (filesystem of .iso images) and assign a virtual optical to logical partitions. In addition you can manage NPIV resources
  8. Shared Storage Pools Introduction (based on SSP1) - Runtime:21 minutes Movie:86 YouTube

    VIOS Shared Storage Pools phase 1 arrived in Dec 2010. It was previously internally called VIOS NextGen. This movie introduces of the pre-reqs, concepts, functions and features available. It allows SAN administration to be rapidly controlled by the VIOS, POWER, AIX Systems Administrators. Its actually very simple to setup and use.
  9. Shared Storage Pools phase 2 Getting Started - Runtime:10 minutes Movie:101 YouTube

    VIOS Shared Storage Pools phase 2 arrived in December 2011. This movie is hands-on Getting started with preparation, cluster create, node add, disk add to the pool and allocating pool space to the virtual disk of a virtual machine. It allows the VIOS administrator to allocate disk space to virtual machines in lets than a second. Its actually very simple to setup and use.

  10. Shared Storage Pools phase 2 Thin Provisioning & Alerts - Runtime:17 minutes Movie:106 YouTube

    VIOS Shared Storage Pools phase 2 has Thin Provisioning as the default virtual disks so disk space gets allocated only when you write to it. This stops unused disk space being spread across all virtual machines (LPARs) but is consolidated in the pool and allows for higher efficiency (i.e. reduce costs). The downside is covered too - you have to monitor monitor the free space as running out will cause big problems. Old fashioned Thick provisioning is available too.

  11. Shared Storage Pools 3 - New Features YouTube

    VIOS Shared Storage Pools phase 3 (SSP3) includes lots of new features including 16 VIOS in a cluster, much higher limits, Better pool stats and IBM Systems Director 6.3.2 now supports SSP3 as a new disk pool type. In addition the larger number of VIOS means much greater flexibility like adopting LPARs and migrating their old style disk space in to a SSP3 and instantly giving Live Partition Mobility whenever you like. This movie is mostly a presentation. New Jan 2013.
  12. Active Memory Deduplication in Theory - Runtime:16 minutes Movie:102 YouTube

    This is a new feature for the Power Systems C models and later, which adds a new feature to the Active Memory Sharing feature that has been available for 4 years. In the back ground the Hypervisor spots and removes duplicate copies of memory pages and then add the release pages back to the free list. This makes much better use of memory and looks like extra free memory. Its actually very simple to setup and use.
  13. Active System Optimiser (ASO) - Runtime:15 minutes Movie:103 YouTube

    This is a AIX 7 and POWER7 performance tuning tool that automatically tunes your logical partition to maximises POWER7 cache affinity and memory affinity. It is like having a level 4 performance tuning genius tuning your machine 24 hours a day. Its actually very simple to setup and use. For a list of useful links Active System Optimizer commands
  14. VIOS Performance Advisor - Runtime:6 minutes Movie:107 YouTube

    The Virtual I/O Server Performance Advisor is very simple to run. A quick download to your workstation, upload the binary to the VIOS and run it during a peak in workload, FTP the output file to your workstation and click on the data file to generate a simple to understand report in a browser. High value advice based on watching the VIOS actually run - get yours here VIOS Performance Advisor wiki page - and "oh yes" - it is totally free to use. Update: this is now part of VIOS 2.2.2+ look for the "part" command.
  15. Java Performance Advisor for AIX - Runtime:9 minutes Movie:109 YouTube

    The Java Performance Advisor for AIX is very simple to run. A quick download to your workstation, upload the files to AIX and run it against your large Java processes, FTP the output file to your workstation and click on the data file to generate a simple to understand report in a browser. You can control how aggressive it will make recommendations based on your skill level and the importance of the workload it looks at your configuration and the resources uses by the Java processes which you point it at.

  16. SDMC to HMC Migration - Runtime:14 minutes Movie:111 YouTube

    The withdrawn Systems Director Management Console - hardware appliance (SDMC) and the Hardware Management Console (HMC) are basically the same machine running different software so migrating from SDMC to HMC is straight forward providing you save some setup information before you boot the HMC install media. This movie steps through the information capture part. Once the HMC is installed and the network details are added back the HMC will discover the machines, LPAR and profiles details from the service processors.
