RAID是Redundant Array of Inexpensive Disks的缩写,按文译义是廉价冗余磁盘阵列,一般就称为磁盘阵列。它的原意是把若干相对便宜的驱动器组合起来成为逻辑上单独的驱动器,以便获得容错数据冗余的能力,恢复由于驱动器故障而可能会丢失的数据,而且价格与相当容量的硬盘机相比还要便宜些。 RAID系统的基本元部件包括2个或更多的驱动器和RAID软件。大多数RAID系统还包括1个或更多的SCSI卡,用于提高Mac机内置SCSI端口的性能。RAID 3和5系统通常适用于服务器,并往往装有 RAID is Redundant Array of Inexpensive Disks acronym, according to the text is cheap redundant disk array, generally referred to as the disk array. Its intent was to combine several relatively inexpensive drives into logically separate drives in order to gain fault-tolerant data redundancy, recover data that might be lost due to drive failure, and cost as much as a comparable hard drive It’s cheaper The basic components of a RAID system include 2 or more drives and RAID software. Most RAID systems also include 1 or more SCSI cards to improve the performance of the Mac machine’s built-in SCSI port. RAID 3 and 5 systems are generally suitable for servers and are often installed
