Lustre


Lustre is a parallel-distributed filesystem driven by the open source community and is available under GNU General Public License. In Lustre, a single server is responsible to store and manage metadata. Thus, the I/O request from the client is totally dependent on single server's computing power, which is quite low for an enterprise-level consumption. Like iRODS and HDFS, Lustre is suitable to store a small quantity of big files rather than both small and big files. Similar to iRODS, Lustre manages an index file that maintains physical addresses mapped with filenames, which makes its architecture traditional and prone to performance bottlenecks. Lustre does not have any mechanism for node failure detection and correction. In the event of node failure, clients have to connect to another node themselves.
