Peer-to-peer redundant file server system and methods

摘要

Peer-to-peer redundant file server system and methods include clients that determine a target storage provider to contact for a particular storage transaction based on a pathname provided by the filesystem and a predetermined scheme such as a hash function applied to a portion of the pathname. Servers use the same scheme to determine where to store relevant file information so that the clients can locate the file information. The target storage provider may store the file itself and/or may store metadata that identifies one or more other storage providers where the file is stored. A file may be replicated in multiple storage providers, and the metadata may include a list of storage providers from which the clients can select (e.g., randomly) in order to access the file.

1. A storage system comprising:
a client; and at least one storage provider in communication with the client over a communication network, the storage provider including a plurality of storage servers, each server including a plurality of storage nodes, wherein the storage nodes are grouped into peer sets with one storage node of each peer set associated with one storage server of the plurality of storage servers, wherein each storage node of a peer set is configured for synchronization of file storage metadata and file data with other storage nodes of the peer set, wherein the storage nodes of each peer set have different roles when interacting with client requests.
