"深入理解RAID存储技术基础：概念、原理及应用"

RAID Arrays are a fundamental aspect of storage technology, providing redundancy and performance enhancements for data storage systems. This module, titled "RAID Arrays", aims to provide a comprehensive understanding of RAID and its various levels. In this module, the basic concepts of RAID are explained, including the needs it addresses and the principles on which it is built. RAID, or Redundant Array of Independent Disks, is a technology that involves grouping multiple disks together to create a single logical unit. By distributing data across multiple disks, RAID offers increased reliability, fault tolerance, and performance. One of the key objectives of this module is to compare and contrast common RAID levels. RAID levels refer to different configurations of disk arrays, each offering a unique balance of performance, reliability, and storage capacity. The module discusses popular RAID levels such as RAID 0, RAID 1, RAID 5, and RAID 10, outlining the characteristics and trade-offs of each. Overall, this module serves as a valuable resource for IT professionals seeking to enhance their knowledge of storage technology. By understanding RAID arrays and their implications, professionals can make informed decisions when designing and managing storage systems. Copyright © 2006 EMC Corporation.
