Methods and policies to support a quality-of-storage network

A computer program product for managing data in a Quality-of-Storage (QoSt) network comprising a plurality of nodes, the computer program product comprising:

• one or more computer-readable storage devices and a plurality of program instructions stored on at least one of the one or more computer-readable storage devices, the plurality of program instructions comprising:
• program instructions to receive current QoSt network topology information;
• program instructions to receive a plurality of data streams at a data storage interface of the QoSt network;
• program instructions to perform differentiated treatment upon received data streams in the data storage interface contingent upon at least different types of data in said received data streams based on one or more QoSt attributes;
• and
• program instructions to perform a plurality of data management operations on the data obtained by the plurality of data streams based on the data storage interface and based on said current QoSt network topology information.

A computer system for managing data in a Quality-of-Storage (QoSt) network comprising a plurality of nodes, the computer system comprising one or more processors, one or more computer-readable storage devices, and a plurality of program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors, the plurality of program instructions comprising:

• program instructions to receive current QoSt network topology information;
• program instructions to receive a plurality of data streams at a data storage interface of the QoSt network;
• program instructions to perform differentiated treatment upon received data streams in the data storage interface contingent upon at least different types of data in said received data streams based on one or more QoSt attributes;
