ZFS之父离开Oracle

Oracle公司的副总裁兼资深架构师、以领导开发了著名的创新技术ZFS而知名的Jeff Bonwick 9月27日在自己的博客中宣布,即将从Oracle辞职,转而参与创办一家创业公司,产品还在秘密开发中。

他在博客中深情回忆,作为Solaris团队一员,能够不断创新、改变陈规、成为思想领导着——创造别人竞相模仿的思想。他还认为现在加上Oracle难以匹敌的市场能力与执行力,Solaris和ZFS存储将取得前所未有的成功。他还说,ZFS现在已经成年,虽然还有很多工作要做,但他将注视着社区来完成。为此,他引用了一句名言:放手你的思想,它会走得更远。

Bonwick表示,接下来自己将尝试的全新事物,想法还没有完全成熟,甚至自己还没有完全理解,超出了自己熟悉的领域,很可能会失败。但任何值得尝试的东西一开始都是如此。 

据LinkedIn以及这里的信息,Jeff Bonwick 1987年毕业于特拉华大学数学专业,1990年获得斯坦福大学统计学硕士学位,随后进入Sun公司至今,效力20年,几乎一直在从事Solaris内核相关的开发,从普通工程师成长为Sun的杰出工程师、存储部门的CTO、Sun副总裁,并获得Fellow荣誉。在Oracle收购Sun之后,他继续担任公司副总裁。

Bonwick在技术领域最值得称道的工作是1994年在排除Solaris 2.2内核一个错误时提出的Slab分配器算法(参考他的回忆文章),和2001年他启动并领导开发的新一代文件系统和逻辑卷管理器ZFS(回忆文章)。如今,这两项创新都已经在Linux、FreeBSD等操作系统中得到广泛应用(Appple曾经试图在Mac上实现ZFS,但不知原因地半途而废了)。

ZFS具有管理简单、支持事务性语义、端到端数据完整性和使用廉价硬件即可达到高伸缩性等优势。ZFS是一个128位的文件系统,因此容量惊人。这方面有很多趣闻,其中之一是,Bonwick在解释该系统为什么用128位时曾说,根据摩尔定律64位显然很快就会不够用,而要想用完128位文件系统的存储能力几乎是不可能的,因为所需能量超过将地球上的海洋加热到沸腾。(请在这里见识他一连串令人眼花缭乱的演算,呵呵,但愿我们人类没有接管整个宇宙的野心。)ZFS的名字来历也很有意思,参见这里。Bonwick 2007年在ACM Queue谈过文件系统的未来,推荐参考。

让我们祝福并继续关注Bonwick的下一个技术传奇。
