What is logical partition (LPAR)? | Definition from TechTarget
WEBA logical partition (LPAR) is a subset of a computer's processor, memory and I/O resources that behaves much like a physical server. A computer can host multiple LPARs, each one running independently of the other.
Mainframe hardware: Logical partitions (LPARs) - IBM
WEBLogical 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
WEBA logical partition (LPAR) is a subset of a computer's hardware resources, virtualized as a separate computer. In effect, a physical machine can be partitioned into multiple logical partitions, each hosting a separate instance of an operating system.
What is LPAR? | Webopedia
WEBMay 24, 2021 · LPAR – logical partitioning. Short for logical partitioning, a system of taking a computer’s total resources – processors, memory and storage — and splitting them into smaller units that each can be run with its own instance of the operating system and applications. Logical partitioning, which requires specialized hardware circuits, is ...

WEBApr 6, 2023 · Logical partitioning is the ability to make a server run as if it were two or more independent servers. When you logically partition a server, you divide the resources on the server into subsets called logical partitions.
What is a Logical Partition? - Computer Hope
WEBUpdated: 10/11/2017 by Computer Hope. A logical partition, also known as LPAR, is a portion of a computer's hardware resources that is set aside and virtualized as an additional computer. A single computer can have multiple logical partitions, each with its own operating system and hardware resources to utilize.
What is an LPAR? - Tech-FAQ
WEBLPAR (Logical Partitioning) is a way of subdividing all of a computer's resources, including the memory, storage, and processors, and splitting them up into smaller logical units that can each be run as a separate part of the operating system (OS).

Logical Partitioning and Dynamic LPAR - IBM
WEBIn a static LPAR configuration, individual processors, 256 MB memory blocks, and I/O adapter slot resources are placed under the exclusive control of a given logical partition. One of the main advantages of the LPAR implementation is that it gives fine-grained allocation control over these individual resources, allowing them to be combined in ...
