disk array

基本解释

The primary server has write access to a disk or disk array, while all SDS servers have read-only access.
主服务器拥有对一个磁盘或磁盘阵列的写访问权，而所有 SDS 服务器则仅拥有只读访问权。
Once the hybrid NAS/SAN server grants access permission，clients connect directly to the SAN disk array for high-speed file data transfer.
一旦混合的NAS/SAN服务器授予存取权限，客户机就直接连到SAN磁盘阵列，进行高速文件数据传输。

RAID-Z is not the only type of disk array available to ZFS. Mirrors are usually faster and less memory-consuming, but require equal numbers of hard drives to use it.
RAID-Z 不是唯一可用于 ZFS 的磁盘阵列类型，镜像速度通常更快且消耗的内存更少，但需要等量的硬盘驱动器才能使用它。

The secret to packing that much information on such small real estate--about 15 times denser than the densest data storage device currently in existence--is self-assembly, or tricking the disk's materials into organizing into an array of data-storing dots packed far tighter than what could be accomplished with current techniques.

磁盘阵列
Because of its structure it can correct not only random errors but also outburst errors. So it is widely used in many communication systems and digital storage equipment, for examples deep-space communication, optical fiber communication,hard disk array, DRAM,CD etc.
由于其特有的结构特点,既适宜纠正随机错误,更适宜纠正突发错误,因而被广泛地用于各种通信系统及数据存储中,如深空通信、移动通信、光纤通信、磁盘阵列、DRAM、光盘等系统。
