Abstract
A cluster of one or more computing devices is operably coupled to a plurality of storage devices. Each computing device in the cluster comprises a frontend and a backend. The backend comprises a plurality of buckets. Each bucket is operable to build a failure-protected stipe that spans two or more of the plurality of the storage devices. A file system comprises one or more failure-protected stipes. A client other than the one or more computing devices in the cluster is operable to access at least a portion of the file system via a stateless mount string comprising a cryptographically-signed key.
Claims20
A system comprising:
- a local computing device;
- and
- a plurality of storage devices, wherein:
- a computing device is operable to build a plurality of failure-protected stripes,
- each failure-protected stripe comprise a plurality of storage blocks,
- each storage block of a failure-protected stripe is located in a different storage device of the plurality of storage devices,
- the plurality of failure-protected stripes is accessible by a first external computing device, and
- a request, to access the plurality of failure-protected stripes, comprises a stateless mount string.
A method comprising:
- receiving a stateless mount string from a first external computing device;
- and
- granting the first external computing device access to a file system according to the stateless mount string, wherein:
- the file system comprises a plurality failure-protected stripes,
- each failure-protected stripe comprises a plurality of storage blocks, and
- each storage block of a failure-protected stripe is located in a different storage device.
