CenOs下 RAID:廉价磁盘冗余阵列(Redundant Array of Independent Disks)部署,程序员大本营,技术文章内容聚合第一站。
RAID全称是独立磁盘冗余阵列(Redundant Array of Independent Disks),基本思想是把多个磁盘组合起来,组合一个磁盘阵列组,使得性能大幅提高。 RAID分为几个不同的等级,各个不同的等级均在数据可靠性及读写性能做了不同的权衡。实际工作中根据自己的业务需求选择不同的RAID方案。 RAID 的实现方式: 外接式磁盘阵列:通过...
RAID ( Redundant Array of Independent Disks )即独立磁盘冗余阵列,通常简称为磁盘阵列。简单地说, RAID 是由多个独立的高性能磁盘驱动器组成的磁盘子系统,从而提供比单个磁盘更高的存储性能和数据冗余的技术。 RAID 是一类多磁盘管理技术,其向主机环境提供了成本适中、数据可靠性高的高性能存储。 SNIA 对 RAID 的...
磁盘阵列(DiskArray)是由'一个硬盘控制器'来控制'多个硬盘的相互连接',使多个硬盘的'读写同步',减少错误,增加效率和可靠度的技术。 2.什么是RAID? RAID是RedundantArrayof Inexpensive Disk的缩写,意为廉价冗余磁盘阵列,是磁盘阵列在技术上实现的理论标准,其目的在于减少错误、提高存储系统的性能与可靠度。常用的等...

独立硬盘冗余阵列(RAID, Redundant Array of Independent Disks),旧称廉价磁盘冗余阵列(Redundant Array of Inexpensive Disks),简称磁盘阵列 RAID的基本思想 其基本思想就是把多个相对便宜的硬盘组合起来,成为一个硬盘阵列组,使性能达到甚至超过一个价格昂贵、容量巨大的硬盘。 简单来说,RAID把多个硬盘组合成为一个逻辑...
A RAID (Redundant Array of Independent Disks) is a data storage scheme that uses two or more drives accessed in combination to improve fault tolerance. Initially used with servers, desktop PCs are increas- ingly using RAID controller and extra ATA or SCSI disks. Newer system boards often have...
Chapter 17. Redundant Array of Independent Disks (RAID)The basic idea behind RAID is to combine multiple small, inexpensive disk drives into an array to accomplish performance or redundancy goals not attainable with one large and expensive drive. This array of drives appears to the compu...
An apparatus includes a plurality of drives configured as a redundant array of independent disks (RAID) and drive array controller logic to: calculate a first partial parity log (PPL) value for a first write operation that targets a first active stripe of the plurality of drives; store the ...
