Ceph PB 级分布式文件系统

Ceph是一个 Linux PB 级分布式文件系统。Ceph 最初是一项关于存储系统的 PhD 研究项目,由 Sage Weil 在 University of California, SantaCruz(UCSC)实施。


Ceph v0.90 发布,此版本是圣诞节前最后一个开发版本!此版本包括一些 librados 和 librbd 的 API 清理和大量的 OSD,MDS,RGW 和 CRUSH 方面的 bug 修复;OSD gets support for discard(SSDs 方面也有潜在的帮助,但是默认是关闭的);改进了 ceph-disk。

接下来两个开发版本将会有大量改进,请继续关注!

Ceph是加州大学Santa Cruz分校的Sage Weil(DreamHost的联合创始人)专为博士论文设计的新一代自由软件分布式文件系统。自2007年毕业之后,Sage开始全职投入到Ceph开 发之中,使其能适用于生产环境。Ceph的主要目标是设计成基于POSIX的没有单点故障的分布式文件系统,使数据能容错和无缝的复制。2010年3 月,Linus Torvalds将Ceph client合并到内 核2.6.34中。IBM开发者园地的一篇文章 探讨了Ceph的架构,它的容错实现和简化海量数据管理的功能。
