在http://www.gluster.com/news.php上边有一段相关的描述:
No metadata dependencies - metadata management is frequently a source of performance bottlenecks, particularly when there are a very large number of files, and can be a single point of failure in traditional file systems. GlusterFS eliminates this problem with intelligent data placement, an automatic data distribution method that optimizes the use of resources and eliminates metadata bottlenecks.
看了一些文档,但还是不清楚glusterfs是怎么把元数据这个概念去掉的? 还有就是它是怎样管理文件/数据的? 没有元数据这个是跟一些比较流行的集群文件系统不一样的,这个理解起来比较麻烦… 况且E文不是很好,不知哪位仁兄看过的帮忙解解疑惑… 谢过~~~ |
