Mainframe hardware: Logical partitions (LPARs) - IBM
Logical partitions (LPARs) are, in practice, equivalent to separate mainframes. Each LPAR runs its own operating system. This can be any mainframe operating system; there is no need to run z/OS®, for example, in each LPAR. The installation planners may elect to share I/O devices across several LPARs, but this is a local decision.

Logical partition - Wikipedia
LPARs (with sufficient certification) safely allow combining multiple test, development, quality assurance, and production work on the same server, offering advantages such as lower costs, faster deployment, and more convenience.

What is logical partition (LPAR)? | Definition from TechTarget
The ability to create and move logical partitions (LPARs) is one of the key features of IBM PowerVM enterprise-grade virtualization product that runs AIX, IBM i and Linux. It combines hardware, firmware and software to serve as a foundation for virtualizing CPU, storage and network resources.

How to create Logical partition (Lpar) using HMC v10 - Tech2Fun
This guide gets you started with a typical creation for a logical partition (LPAR) using HMC v10. The Create Logical Partition wizard on the Hardware Management Console (HMC) guides you through the procedure of creating logical partitions and partition profiles on your server. To create a partition, complete the following steps: In the navigation area, click Resources, and then select All ...

Monitor LPARs and regions - Dynatrace Docs
Dynatrace can help you to achieve such a cost-effective IBM Z configuration by providing infrastructure metrics for LPARs (represented as Hosts) and regions (represented as Processes). All metrics listed below are provided by the zDC subsystem as builtin metrics.

Difference between sysplex and lpar? - Mainframe, MVS and zOS Discussion
LPARs came about as a result of the need to split processing resources to keep workloads separate whereas the sysplex is about joining resources together in order to spread the workload across multiple LPARs/machines to improve resilience and scale capacity.

Configuring LPARS to Optimize Performance - Pivotor
So when we total up the LPARs and come to 325GB we do wonder if the rest of that memory could be put to effective use! If you have a plan for using this (e.g. you’re planning on standing up some additional LPARs), then fine.

Mainframe Architecture for Beginners: What are LPARs and Plexes? - LinkedIn
Now, imagine a group of those apartments working together as a single hotel staff. That is a Plex (Parallel Sysplex). A Plex is a cluster of multiple LPARs that act as a single logical unit.

What is LPARs? Competitors, Complementary Techs & Usage
LPARs, or Logical Partitions, are a feature of IBM mainframe and Power Systems servers that allows a single physical server to be divided into multiple virtual servers. Each LPAR operates as an independent system with its own operating system, resources (CPU, memory, I/O), and security domains.

IBM licensing in IBM LPAR infrastructures - ServiceNow
IBM LPARs support both dedicated and shared processor pools. If you are using a dedicated processor pool, in which processor cores are assigned to only one dedicated LPAR, you must license each dedicated processor core that is assigned to the LPAR on which you install or run an IBM software product.
