A comparison of virtualization features of HP-UX, Solaris, and AIX
Most IBM AIX administrators understand the virtualization features available to
them on their System p platform through PowerVM, which is also available on the
System p for Linux. But what about the other UNIX hardware platforms? What do
they have to offer and how do some of their features compare to PowerVM? This
article explores all of these topics in detail.

Virtualization in System p
Capitalize on the benefits virtualization can provide to maximize
the usage of your resources. Virtualization is a modern approach and is available on
all System p(TM) servers, starting from POWER4. This article discusses physical
and logical partitioning, with special relevance to how to implement logical
partitioning.

Enterprise-Wide Unique identifiers
Successful implementation of business continuity in large IBM AIX environments
is dependent upon the elimination of resource conflicts on the supporting computer
systems. Many aspects of business continuity -- such as virtualization, high
availability, and disaster recovery -- require unique identification values for many
of the resource parameters involved in system configuration. Provided in this article
is a discussion and mechanism for generating Enterprise-Wide Unique (EWU) identification values for a wide variety of configuration parameters.

Automating deployment and activation of virtual appliances for IBM AIX and Power Systems
Server virtualization enables you to rapidly provision new environments by
using libraries of virtual image templates, or virtual appliances. Automated
provisioning requires the management of operating system, network, and
application-specific customization. This article provides a sample framework for
automating virtual image deployment and activation on Power Systems, with a
downloadable example that demonstrates how to provision a virtual appliance made up
of IBM WebSphere Application Server V7.0 running on AIX V5.3.

Create a WebSphere Application Server 7.0 virtual appliance for AIX
This article describes a process for creating and using a WebSphere Application
Server (Application Server) virtual appliance for AIX logical partition (LPAR)
virtualization technology. It describes a source LPAR environment for building a
Application Server virtual appliance and specifying the steps involved in preparation
of the environment, including installation of Application Server and custom
configuration needed to ensure that the installed version of Application Server can
function as an appliance. To create the appliance, the prepared environment is used as
a source for an image, saved as a binary file and is described using an Open Virtual
Machine Format (OVF) file. The article concludes with a description of alternative scenarios for sharing the appliance, including one where the appliance is shared across the Internet and another where the appliance is shared within a data center.

DB2 and the Live Partition Mobility feature of PowerVM on IBM System p using storage area network (SAN) storage
Learn about Live Partition Mobility, a feature of the System
p virtualization PowerVM Enterprise edition. See how
Live Partition Mobility
can be applied to DB2 deployments, and how it helps you migrate AIX and Linux partitions and
hosted applications from one physical server to another compatible physical server.
Live Partition Mobility allows hardware maintenance, firmware upgrades, system
maintenance, and on-the-fly server consolidation without application outage.
Setup, configuration, best-practices, and performance characterization for Storage Area Network (SAN)
and DB2 are covered.

Transition to AIX from Solaris
You've been working with Solaris for ten years now and, like many other
companies, you have just started a large server consolidation and migration project
to AIX(R) 6.1 from Solaris 10. Many of the commands are similar, but you need to
know how to work with partitioning and virtualization. What are the partitioning
differences between an IBM(R) and Sun server? Furthermore, what do you need to know
about workload partitions (WPARs) to make a successful transition from containers?
What are some of the similarities and differences between WPARs and zones, and how
does the process differ from creating zones and WPARs? Finally, what can you do on
the IBM System p(TM) that you can't do with Sun servers? These are some of the
questions addressed in this article, with the objective of making your transition
easier.

AIX 6.1 Workload Partitions
Workload Partitions (WPARs) are a new virtualization feature of AIX 6.1.
This article helps you decide whether WPARs are right for your AIX workloads, and
then gives you step-by-step guidance on how to learn more about WPARs and begin
using them.

Live Application Mobility in AIX 6.1
The most popular innovation of AIX 6.1 is arguably workload partitioning. Workload partitioning allows you to have fewer operating system images on your managed system, which is accomplished by allowing virtualization of operating system resources. Live Application Mobility is an important component of workload partitioning and provides for increased availability for workload partitions (WPARs). Simply put, it allows you to move WPARs from one logical partition (LPAR) to another while the WPARs are up and running. It provides automatic, policy-based relocation of workload between systems using WPARs. This article explores how and when to use Live Application Mobility and how to configure a system and its applications to run it.

Partition Load Manager logging and monitoring
Accomplish server resource virtualization with the help of the Partition Load Manager. Because the Partition Load Manager reallocates resources dynamically across partitions based on their workload, conventional tools for monitoring and analyzing resources become useless. So, what’s a developer to do? You can use the On-demand Monitoring System (OMS) tool for the Partition Load Manager. It works as an integral component providing real-time and historical utilization and allocation data.

Securing the Hardware Management Console
Get step-by-step instructions for things you should do during installation of the Hardware Management Console (HMC), measures you can take after installation, and maintenance guidelines to ensure that a secure system stays secure. The HMC, which plays a central role in the IBM virtualization strategy, controls hardware, configures logical partitions (LPAR), and assigns both physical and virtual devices. It is vital to systems management in a virtualized environment.

Logical volume management
Volume management is not new in the -ix world (UNIX, AIX, and so forth). And
logical volume management (LVM) has been around since Linux kernel 2.4v1 and
2.6.9v2. This article reveals the most useful features of LVM2--a relatively new
userspace toolset that provides logical volume management facilities--and suggests
several ways to simplify your system administration tasks. Based on reader feedback,
the author has updated Listings 10, 14, 15, and 16. -Ed.
