转载 先看Data blocks(也叫逻辑块,oracle块,页)吧,oracle存储数据都是在这些数据块中,一个数据块是磁盘上数据库物理空间一系列物理字节的组成.    比Data blocks更高一层的逻辑数据块空间是extent,一个extent是由一系列临近的存储信息的数据块组成.    最高一层的逻辑结构是segment,一个segment是同一表空间extents的一个集合.每一个segment有不同的数据结构.如每一个表的数据就存储在自己的data segment,每一个索引存储在…

大家在使用Docker的过程中,有没有想过,Docker在本地存储镜像时把文件存储在哪里了呢?有没有对文件的总大小做一定的限制呢?能不能调整本地存储的位置及总限制大小呢?今天,我们就从这些问题入手,来讨论一下Docker的存储优化方案. 一.Docker的默认存储策略 Docker提供了查看配置信息的命令,即docker info命令,通过该命令可以查看Docker的各种系统层面的信息,如当前运行的容器数.镜像数.Docker版本等信息,其中就包括了存储信息. 我们输入docker info命令…

Storage Pool的起源 ========================== Some time ago, EMC introduced the concept of Virtual Provisioning and Storage Pools in their Clariion line of arrays. The main idea for doing this is to make management for the storage admin simple. The trad…
