Accepted Answer

RAID stands for Redundant Array of Independent Disks. It is a data storage technology that combines multiple physical drives into a single logical unit for improved performance, reliability, or both.

RAID is used to enhance data storage performance and/or provide fault tolerance.
There are different RAID levels, such as RAID 0, RAID 1, RAID 5, RAID 10, etc.
RAID 0 offers improved performance by striping data across multiple drives.
RAID 1 provides data redundancy by mirroring data on multiple drives.
RAID 5 combines striping and parity for both performance and fault tolerance.
RAID 10 combines mirroring and striping for improved performance and redundancy.
LVM (Logical Volume Manager) is a software-based approach to manage disk storage in Linux systems.
LVM allows for dynamic allocation and resizing of logical volumes, providing flexibility and ease of management.
Logical volumes can span multiple physical disks and can be resized without disrupting the system.
LVM provides features like snapshots, thin provisioning, and volume mirroring for data protection.
