Parallel File System
SearchStorage, Thursday, May 23rd, 2024
A parallel file system is a software component designed to store data across multiple networked servers. It facilitates high-performance access through simultaneous, coordinated input/output (I/O) operations between clients and storage nodes.
Parallel file system implementations can span thousands of server nodes and manage petabytes or exabytes of data. Users typically deploy high-speed networking, such as Fast Ethernet, InfiniBand and proprietary technologies, to optimize the I/O path and enable greater bandwidth.
How does a parallel file system work?
Parallel file systems break up a data set and distribute, or stripe, the blocks to multiple storage drives that are located in local and remote servers. Users don't need to know the physical location of the data blocks to retrieve a file. Systems use a global namespace to facilitate data access. These systems often use a metadata server to store information about the data, such as the file name, location and owner.
