	LPAR Overview
		Dynamic logical partitioning (LPAR) is a system architecture approach that promises to revolutionize corporate IT infrastructures by enabling the capability to virtualize hardware resources that can be shared by multiple independent operating environments.
		LPAR on eServer i5 is supported by i5/OS and AIX 5L - IBM operating systems, and by the Linux operating system available from one or more Linux distributors.
		These clients have taken advantage of LPAR to benefit from the growing industry trend and the desire to optimize IT investments and resource virtualization through consolidation of hardware, software, networks, data centers, and more importantly skills.

		LPAR (Logical Partition) ermöglicht die Aufteilung eines Großrechners in mehrere virtuelle Systeme, auf denen sogar verschiedene Betriebssysteme installiert werden können.
		LPAR Mode = Hardwareressourcen werden in "logische Partitionen" aufgeteilt
		Mit AIX Version 5.2L können die LPARs dynamisch (ohne Reboot) repartioniert werden.

	IBM Redbooks \| pSeries - LPAR Planning
		For AIX 5L Version 5.1, the number of LPARs larger than 16 GB is limited to two in a system with 64 GB of installed memory, because of the memory alignment in AIX 5L Version 5.1.
		LPARs that are larger than 16 GB are aligned on a 16 GB boundary.
		In this scenario, when the second LPAR is installed using all the internal SCSI devices, you must be careful to not override the disks of the first LPAR.

	IBM p690 Configuration Experiments (Site not responding. Last check: )
		Eight of the 32GB nodes are partitioned into four 8-processor/8GB "virtual" (LPAR) nodes, for a total of 32 8-processor nodes.
		As each node will have a maximum of two interfaces into the network when we install the Colony switch, the use of LPAR nodes will increase network bandwidth available to each processor in a partitioned p690 by a factor of four over that of a processor in an unpartitioned node.
		The LPAR nodes partition memory as well as processors, and each runs its own OS, which also impacts memory usage.

		LPAR Tuner is very flexible and lets you set your own policies, or Business Rules, to control the movement of resources during the day.
		LPAR Tuner automatically optimizes every partition for better response times and more reliable operations, without the need for operator intervention, using an advanced, powerful decision-making mathematical algorithm.

	Logical partitioning in the System p5 environment
		Logical partitioning (LPAR) is the ability to logically slice up a single system's CPU, memory, and other resources to create multiple and separate servers.
		Capped prohibits the LPAR from using more processing units than is currently allocated to it.
		If an LPAR is allocated 1.5 processing units but the workload requires 2.2 units, the LPAR would not be allowed access to the additional units, even if they were available in the shared processor pool.

	Curia Vista - Atti parlamentari (Site not responding. Last check: )
		Come dimostra l'esaustivo rapporto sulla valutazione dell'efficacia della LPar, recentemente pubblicato, tale legge non ha raggiunto i suoi obiettivi, ovvero l'effettiva parità tra donna e uomo, in particolare negli ambiti della discriminazione salariale e delle molestie sessuali sul posto di lavoro.
		Sarebbe difficilmente comprensibile perché un licenziamento abusivo ai sensi della legge federale sulla parità dei sessi (LPar) dovrebbe comportare il versamento di un'indennità decisamente superiore a quella prevista in caso di licenziamento ai sensi del Codice delle obbligazioni.
		Infine l'autrice della mozione ritiene che se i datori di lavoro fossero confrontati con multe molto severe, in caso di violazione rispetterebbero in misura maggiore le disposizioni legali.

	IBM: Reconciling CPU Utilization in an LPAR Environment
		Therefore, it is skewed when running in an LPAR when the partition is using shared processors.
		The other difference is that the PRF017 value is of a 100% maximum or total, while the RTM physical processor value is out of N*100% maximum or total, where N is the number of logical processors.
		However, in an LPAR or second level where the processor can be taken out from under VM the logical %CPU can be misleading because the sum used in the denominator (US + EM + SY + WT) can be less than wall clock time.

	Installing Debian GNU/Linux on a p630 LPAR
		Due to the way the LPAR was configures, we had to boot from the second ethernet interface.
		During out first trials we ran into trouble because the kernel could not find a console: we had not compiled in the hvc_console driver due to its dependencies on the magic sysrq key option, which was in the same general configuration section as the kernel debuggers.
		The base system was installed via nfs: since the LPAR had no CD-ROM, we mounted the Debina CD on a remote machine and exported it via NFS.

		LPAR allows workloads from multiple systems to be consolidated to a single iSeries machine, thus significantly cutting IT costs while minimizing risk.
		LPAR involves a single iSeries system’s resources (processors, memory, etc.) being divided to create multiple independent iSeries systems within the same system.
		Each iSeries partition can then be used for different purposes, such as database operation or to separate test and production environments, and can communicate with the other partitions as if they were each in a separate machine.

		While IBM provides facilities to set up and manage logical partitioning (LPAR) through iSeries Navigator (formerly Operations Navigator) and System Service Tools, it does not provide many options for the automation of those tasks on a day-to-day basis, says Tom Huntington, vice president of technical services for Help/Systems.
		Additionally, many companies are hesitant to allow their administrators to manually adjust their logical partitioning resource settings for fear of making a mistake and causing a disruption to a program, he says.
		The utility is composed of two main components: LPAR Manager, which must run in the server's primary partition, and LPAR Explorer, the Java-based user interface where administrators can adjust how Robot/LPAR behaves.
