Directed placement of data in a redundant data storage system
First Claim
1. A data processing apparatus, comprising:
- a metadata store storing information about files that are stored in a distributed data storage system, and comprising a class database;
one or more processing units;
logic coupled to the processing unit(s) and to the metadata store and comprising stored sequences of instructions which, when executed by the processing unit(s), cause;
receiving and storing in the class database a definition of a class of data storage servers comprising one or more subclasses each comprising one or more server selection criteria;
associating the class with one or more directories of the data storage system;
in response to a data client storing a data file in a directory of the one or more directories, binding the class to the data file, determining and storing a set of identifiers of one or more data storage servers in the system that match the server selection criteria, and providing the set of identifiers to the data client;
wherein the set of identifiers identify one or more data storage servers for storing the data file; and
automatically storing the data file on one or more first data storage servers that are identified in the set of identifiers.

Abstract
A data processing apparatus, comprising a metadata store storing information about files that are stored in a distributed data storage system, and comprising a class database; one or more processing units; logic configured for receiving and storing in the class database a definition of a class of data storage servers comprising one or more subclasses each comprising one or more server selection criteria; associating the class with one or more directories of the data storage system; in response to a data client storing a data file in a directory, binding the class to the data file, determining and storing a set of identifiers of one or more data storage servers in the system that match the server selection criteria, and providing the set of identifiers to the data client.

10. A computer-readable storage medium comprising stored sequences of instructions which, when executed by one or more processing unit(s), cause:
-
receiving and storing, in a class database in a metadata store storing information about files that are stored in a distributed data storage system, a definition of a class of data storage servers comprising one or more subclasses each comprising one or more server selection criteria; associating the class with one or more directories of the data storage system; in response to a data client storing a data file in a directory of the one or more directories, binding the class to the data file, determining and storing a set of identifiers of one or more data storage servers in the system that match the server selection criteria, and providing the set of identifiers to the data client; wherein the set of identifiers identify one or more data storage servers for storing the data file; and automatically storing the data file on one or more first data storage servers that are identified in the set of identifiers. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A computer-implemented method, comprising:
-
receiving and storing, in a class database in a metadata store storing information about files that are stored in a distributed data storage system, a definition of a class of data storage servers comprising one or more subclasses each comprising one or more server selection criteria; associating the class with one or more directories of the data storage system; in response to a data client storing a data file in a directory of the one or more directories, binding the class to the data file, determining and storing a set of identifiers of one or more data storage servers in the system that match the server selection criteria, and providing the set of identifiers to the data client; wherein the set of identifiers identify one or more data storage servers on which to store for storing the data file; and automatically storing the data file on one or more first data storage servers that are identified in the set of identifiers; wherein the method is performed by one or more computing devices. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
