storage theory

preface/prehight:
topic: Storage(share fileSystem(可共享文件系统,Access I/O existence bottleNeck,access read/write space slowly),BSD(block storage device,file not share,but access read/write space high),Object storage(both and merit))
brief description:

distributed (Object) fileSystem,block device,SFS(shared filesystem)
MDS(Metadata server) 存放的是数据属性非数据也!数据存在于OSD(object-based storage)
bottleNeck

Access interface (POSIX/MPI(message passing interface))

AFR(Acceptable Failure Rate)
DHT(Distributed Hash Table)

Redundancy protection,DP(Data Protect) method
1,mirror
2,more than a copy(duplicate,repetition)
