虽然模式可以根据目的及输入输出参数的交互组合在一起，但组件模式的语义兼容性并不容易进行机械性的分析。

Although patterns may be combined, based on their intents and interactions of input and output parameters, semantic compatibility of the component patterns are not easily analyzed mechanically.

这种细粒度的版本标识对开发者和用户都非常有益；这些标识的简洁语义有助于判断兼容性和开发过程中的调试。

This fine level of granularity is useful to both developers and users; each of these things has precise semantics that helps in figuring out compatibility and debugging.

它利用POSIX的兼容性完成所有这些任务，允许它对当前依赖POSIX语义(通过以Ceph为目标的改进)的应用进行透明的部署。

It does all of this with the goal of POSIX compatibility, allowing it to be transparently deployed for existing applications that rely on POSIX semantics (through Ceph-proposed enhancements).
