Google File System
This document provides an overview of the Google File System (GFS). It describes the key components of GFS including the master server, chunkservers, and clients. The master manages metadata like file namespaces and chunk mappings. Chunkservers store file data in 64MB chunks that are replicated across servers. Clients read and write chunks through the master and chunkservers. GFS provides high throughput and fault tolerance for Google's massive data storage and analysis needs.
