# What Is a Logical Partition A logical partition, often abbreviated as LPAR, is a virtual division of a physical server or mainframe computer into multiple independent computing environments. Each partition functions as its own entity with its own operating system, memory, and processing resources, while sharing the underlying hardware. In a logical partitioning setup, the physical server's resources are divided and allocated to each LPAR, allowing multiple operating systems to run concurrently on the same hardware platform. This concept is used in server virtualization to optimize resource utilization, enhance system availability, and improve overall efficiency. The term "logical" refers to the fact that these partitions are software-defined and not physically separate from the hardware. The operating system within each LPAR believes it has exclusive access to the resources, even though they are shared among multiple instances. The hypervisor, or virtualization layer, manages the allocation and isolation of resources, ensuring that one partition's activities do not affect the performance of others. Logical partitions are commonly used in data centers, where high server utilization and workload flexibility are crucial. They enable administrators to scale resources up or down, migrate workloads between partitions, and perform maintenance without disrupting other running applications. This makes LPARs an effective solution for managing diverse workloads, consolidating servers, and improving overall IT infrastructure management.

When a hard disk is partitioned into different sections, it is divided into Primary and Extended partitions. The Extended partition can, in turn, be further divided into multiple Logical partitions.

Definition: A logical partition divides a hard drive into distinct, independent sections that can hold files and, in some cases, applications as well. It is a kind of partition created within an extended partition on a hard drive.

History: The idea of logical partitioning can be traced back to the early days of computing when computers relied on hard disks for data and program storage. In the early 1980s, IBM introduced the concept of extended partitions and logical drives, enabling users to split a single hard drive into multiple smaller segments or partitions.

Previously, hard drives were restricted to having no more than four primary partitions, constraining the number of operating systems or applications that could be installed on a single computer. The advent of extended partitions and logical drives enabled users to create extra partitions within the extended partition, providing more space for data storage and non-bootable programs.

Hardware Partitioning: Also referred to as physical partitioning, this is the process of dividing a computer's hardware resources, such as memory and processing capacity, into distinct, self-contained segments that can be utilized by different applications or operating systems independently.

Hardware partitioning is frequently employed in large, enterprise-scale systems to enable the concurrent execution of multiple applications or operating systems on a single piece of physical hardware without any interference or resource conflicts. It also facilitates virtual environments for testing and development purposes, as well as isolated environments for enhancing security or meeting compliance requirements.

What's the Difference Between Logical, Primary, and Extended Partitions

In this section, let me briefly explain to you what a Primary Partition and an Extended Partition are:

What is a Primary Partition? A primary partition is a specific type of partition in a computer's hard drive or solid-state drive (SSD) that is used to organize and allocate storage space. In the context of disk partitioning, it is one of the fundamental ways to divide a disk into distinct sections, allowing multiple operating systems or different data storage areas to coexist on the same physical drive. When you first format a hard drive, you can create up to four primary partitions, depending on the disk layout and the file system being used. In the older Master Boot Record (MBR) partitioning scheme, this limit is fixed, while the newerGUID Partition Table (GPT) allows for a significantly higher number of primary partitions. Each primary partition can function as an independent unit, with its own file system and volume label. They can be formatted with various file systems like NTFS, FAT32, or exFAT, depending on the operating system and requirements. A primary partition can also be designated as the active or bootable partition, which contains the necessary files to start the computer. If you need more than four partitions on an MBR disk, you can create an extended partition, which acts as a container for one or more logical drives. However, note that extended partitions cannot be bootable, and they are not directly equivalent to primary partitions. In summary, a primary partition is a crucial component of disk organization, enabling users to divide their storage into separate areas for different purposes or to accommodate multiple operating systems.

The primary partition on a hard drive is the one that can be designated as active for the BIOS to locate, and it is where the Windows operating system and other data can be stored. In simpler terms, a primary partition is essential for booting up a computer. Typically, a hard disk drive is restricted to having three primary partitions and one extended partition, or a maximum of four primary partitions in total.

What is an Extended Partition?

A partition that is further divided into logical disks is referred to as an extended partition. Unlike a primary partition, you don't need to assign it a drive letter or format it with a file system. Instead, you can expand the partition by creating multiple new logical drives within the operating system.

Comparison Logical Partition Primary Partition Extended Partition
Importance Enables it to run its copy of the operating system and related programs Can only boot the legacy MBR bootloader from a primary partition Can add more logical drives by using the operating system
Bootable or Not Windows cannot boot from a logical partition It is bootable, and you cannot boot your PC without it Not bootable
Translation:
Comparison Logical Partition Primary Partition Extended Partition
Significance Allows it to run its own operating system and associated programs Can only boot the legacy MBR boot loader from a primary partition Can create additional logical drives using the operating system
Bootable or Not Windows cannot boot from a logical partition It is bootable, and your PC cannot start without it Not bootable

You can only have one primary partition on your drive, so there isn't a better choice between a primary or logical partition. Your computer won't be able to start otherwise. There's no difference in storage capacity between the two partition types. It's best to create logical partitions on your drive if you need more than four partitions on an MBR (Master Boot Record) disk.

What Is a Logical Partition FAQs

If you have more questions regarding logical partitions, refer to the following frequently asked questions and their corresponding answers:

1. What does logical partition mean? Logical partition refers to a method of dividing a computer's physical resources, such as memory and processing power, into separate, independent sections, each functioning as a virtual machine or an individual operating system. This is often done in mainframe and server environments to optimize resource utilization, improve efficiency, and enable multiple workloads to run concurrently on a single physical hardware system. Each logical partition, or LPAR, has its own CPU, memory, and storage resources, which can be allocated and adjusted independently without affecting other partitions.

A logical partition is a section of a PC's hardware resources that have been virtualized to appear as a separate PC. There can be an unlimited number of logical partitions on a disk.

2. Why do we use logical partitions? We use logical partitions for several reasons, primarily to optimize the utilization and management of storage resources in a computer system. Here are some key benefits: 1. **Resource Allocation**: Logical partitions allow you to divide a physical hard drive into multiple, independent sections, each with its own file system and operating system. This enables better allocation of resources, as different partitions can have varying amounts of space assigned to them. 2. **Flexibility**: With logical partitions, you can run multiple operating systems on the same machine, providing flexibility for software testing, development environments, or simply having separate workspaces for different tasks. 3. **Isolation and Stability**: By separating different applications or data sets into distinct partitions, you can minimize the risk of one component affecting the stability or performance of another. For instance, a crash in one partition won't affect the others. 4. **Ease of Management**: Logical partitions make it easier to manage disk space. You can resize, format, or backup individual partitions without impacting the entire drive. This allows for more efficient organization and maintenance. 5. **Security**: Partitioning can provide an additional layer of security by isolating sensitive data in a separate partition that can be encrypted or have restricted access. 6. **Performance**: In some cases, logical partitions can improve system performance by allowing the operating system to better manage resources like memory and I/O operations. Overall, logical partitions offer a more organized, flexible, and manageable approach to storage, enhancing the overall functionality and efficiency of a computer system.

A logically partitioned server can reduce the number of physical servers needed within an organization. Multiple servers can be combined into a single system with logical partitions. This eliminates the need for additional hardware and associated costs. Each resource group can be managed separately, with its own operating system and applications.

3. Should I use a primary or a logical partition?

There isn't a clear winner between logical and primary partitions. Both are quite similar. While a hard drive can have an unlimited number of logical partitions, it can only support up to four primary partitions.
