Abstract
Abstract A distributed storage system is disclosed in which an originating storage location establishes the criteria for storage management for a file. When the file is transmitted to other, subsidiary storage locations, it is accompanied by information controlling the storage of the file. For example, the duration of storage will be controlled by the control information. When a master file is deleted from an archive, in accordance with the criteria established at the time of storage, copies of the file at subsidiary locations can either be rendered inaccessible or alternately the storage management for that file can be changed. A feature is the distribution of storage management control information along with the file to diverse storage locations in a complex data processing system.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
92 words
In a data processing system having a plurality of storage devices, including an originating storage device and an archiving storage device, a method for parallel system managed storage for objects, comprising the steps of: receiving an object file at an originating storage location; assembling control information to control the storage of said file in a storage device; transmitting a copy of said file and said control information to a second storage device in said data processing system; performing said control functions at said second storage device in response to said control information.
Claim 2
Dependent Claim
20 words
The method of claim 1 which further comprises: said control information controlling a duration of storage for said object file.
Claim 3
Dependent Claim
50 words
The method of claim 2 which further comprises: deleting said object file at said originating storage location; reading said control information at said second storage location associated with said copy of said file; deleting said copy of said file at said second storage location, in response to said control information.
Claim 4
Dependent Claim
20 words
The method of claim 1, which further comprises: selectively performing alternate local option control functions at said second storage device.
Claim 5
Dependent Claim
24 words
The method of claim 1, wherein said control information controls the migration of said object file to a third storage device in said system.
Claim 6
Dependent Claim
34 words
The method of claim 1, wherein said control information controls the migration of said object file to a third storage device in said system after a duration from said receiving at said originating location.
Claim 7
Dependent Claim
120 words
In a data processing system having a plurality of storage devices, including an originating storage device and an archiving storage device, a subsystem for parallel system managed storage for objects, comprising: receiving means for receiving an object file at an originating storage location; assembling means coupled to said receiving means, for assembling control characters to control the storage of said file in a storage device; transmitting means coupled to said assembling means, for transmitting over a communication link a copy of said file and said control characters to a second storage device in said data processing system; control means coupled to said communication link, for performing said control functions at said second storage device in response to said control characters.
Claim 8
Dependent Claim
20 words
The subsystem of claim 7 which further comprises: said control characters controlling a duration of storage for said object file.
Claim 9
Dependent Claim
76 words
The subsystem of claim 8 which further comprises: first deleting means coupled to said receiving means, for deleting said object file at said originating storage location; reading means coupled to said control means, for reading said control characters at said second storage location associated with said copy of said file; second deleting means coupled to said reading means, for deleting said copy of said file at said second storage location, in response to said control information.
Claim 10
Dependent Claim
14 words
The subsystem of claim 7, wherein said object file is an image object file.
Claim 11
Dependent Claim
24 words
The subsystem of claim 7, wherein said control information controls the migration of said object file to a third storage device in said system.
Claim 12
Dependent Claim
27 words
The subsystem of claim 7, wherein said control information controls the migration of said object file to a third storage device in said system after a duration.
