完整的源代码和维护工具、手册 • 编写IO驱动比较容易，容易扩展支持新的存储系统 • 代码独立，容易编译、调试、修改，适应性强让TGT支持curve • 编写curve驱动，底层异步提交I/O，pipeline • 利用NEBD PART 1接口，需要与nebdserver运行在同一台机器 • 支持共享打开，两台TGT服务器可以同时打开一个curve卷 • 让Initiator可以使用multipath

CurveBS I/O processing flow Before introducing IO processing flow, we first describe the overall architecture, data organization and topology structure of CURVE. CurveBS uses the central node Metadata operation. CurveFS architecture Curvefs implements the file system interface based on FUSE. 1. Fs-meta Cluster is used to manage the inode and dentry metadata of files. The architecture is like CurveBS
