What is redundant array of independent disks in SAP BC-DB - Database Interface, Database Platforms?

SAP Term: redundant array of independent disks

• Component: BC-DB

• Component Name: Database Interface, Database Platforms

• Description: A hardware-based technology that supports disk redundancy by using disk mirroring. RAID systems contain an array of disk spindles sharing a common controller that distributes data on the disks in a way transparent to the user. Most RAID systems include internal error checking to keep data available even if single disks fail. There are different RAID levels, characterized by the methods of distributing dataand check bits on the disks in the system. Another technique to achieve disk mirroring is the software-based LVM technology Logical Volume Manager.

• Key Concepts: 
  Redundant Array of Independent Disks (RAID) is a storage technology that combines multiple hard drives into a single logical unit. It is used to increase the performance, reliability, and capacity of a storage system. RAID can be used with any type of storage device, including hard disks, solid-state drives, and optical drives. RAID is commonly used in enterprise-level storage systems.
  
  How to use it: 
  RAID can be used to increase the performance of a storage system by allowing multiple drives to be accessed simultaneously. This can improve the speed of data access and reduce latency. RAID can also be used to increase the reliability of a storage system by providing redundancy in case one or more drives fail. Finally, RAID can be used to increase the capacity of a storage system by combining multiple drives into a single logical unit.
  
  Tips & Tricks: 
  When using RAID, it is important to choose the right RAID level for your needs. Different RAID levels offer different levels of performance, reliability, and capacity. It is also important to ensure that all drives in the array are compatible with each other and that they are configured correctly. Finally, it is important to regularly monitor the health of the array and replace any failed drives as soon as possible.
  
  Related Information: 
  RAID is commonly used in enterprise-level storage systems, but it can also be used in consumer-level systems. For more information on RAID levels and how to configure them, please refer to the official documentation from your storage device manufacturer or consult an IT professional.
