They said they would never have been involved in such a program. Design[ edit ] Google File System is designed for system-to-system interaction, and not for user-to-system interaction.

How the Google File System Works

It turns the entire network into a massive computer, with each individual computer acting as a processor and data storage device. It is also designed and optimized to run on Google's computing clusters, dense nodes which consist of cheap "commodity" computers, which means precautions must be taken against the high failure rate of individual nodes and the subsequent data loss.

Each chunk is assigned a unique bit label by the master node at the time of creation, and logical mappings of files to constituent chunks are maintained. Aggregating a large number of servers also allows big capacity, while it is somewhat reduced by storing data in three independent locations to provide redundancy.

Files are divided into fixed-size chunks of 64 megabytessimilar to clusters or sectors in regular file systems, which are only extremely rarely overwritten, or shrunk; files are usually appended to or read.

NextEra Energy Resources sold Google a twenty-percent stake in the project to get funding for its development. Files which are in high demand may have a higher replication factor, while files for which the application client uses strict storage optimizations may be replicated less than three times - in order to cope with quick garbage cleaning policies [3].
