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.
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.
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.
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.

In details are N Port Id Virtualisation (NPIV), virtual DVD and virtual tapes, Heterogeneous Multipathing and improved VIOS CEC level monitoring of virtual disks and virtual networks.
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.
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.
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.
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.
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
