我不太明白斑竹说的意思,我理解的“并行文件系统”有两个方面
1、是不同的node可以同时读取和写入同一个文件系统中的相同、不同的文件或数据(类似ORACLE RAC中的文件系统共享方式)
2、是在同一node上需要读取 ...
1. cluster aware/wide FS ( TruCluster cluster wide FS, ocfs, ocfs2, polyserv, GFS ....)
2. Parallel FS (lustre, SFS, GPFS, PVFS.....)
in cluster FS, FS are locate on classic storage system such as DAS, NAS(netapp filer), SAN.
in Parallel FS, FS are seperated on different computing system that Act as "storage Nodes" and "Storage Meta Nodes". Normally we use cheap IA server present those "nodes". for extend solution, normally we attach some cheap DAS storage to some nodes.
that's totally different.
Tons of research & analysis information from the internet, i don't think it is worth to discuss further if anyone still lack of basic concepts.
