Abstract
Abstract A system and method for managing the nonvolatile memory capacity of individual workstations within a data processing network having a multiplicity of workstations with resident nonvolatile memory devices. In the context of the embodying network, the invention provides for a selective querying of workstations to determine unused disk capacity, a comparison of such capacity to a threshold defined for the respective workstation, and the generation of an event message indicating sub-threshold capacity. The event is subject to local or network logging, and can include information identifying the workstation and its disk capacity status. A refinement of the invention contemplates the reallocation of disk capacity within the network to avoid premature termination of programs executing on a workstation upon the finding of a sub-threshold capacity in the workstation.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
85 words
A system for managing memory capacity in a data processing network connected to communicate data in specified protocol between multiple workstations with resident nonvolatile memory devices, comprising: means for selectively querying a workstation connected on the network to determine the respective unused nonvolatile memory; means for comparing the determined unused nonvolatile memory to a respective minimum capacity threshold value; and means for generating event response data in the network to signify that the unused nonvolatile memory at the queried workstation is below the threshold value.
Claim 2
Independent Claim
85 words
A system for managing memory capacity in a data processing network connected to communicate data in specified protocol between multiple workstations with resident nonvolatile memory devices, comprising: means for selectively querying a workstation connected on the network to determine the respective unused nonvolatile memory; means for comparing the determined unused nonvolatile memory to a respective minimum capacity threshold value; and means for generating event response data in the network to signify that the unused nonvolatile memory at the queried workstation is below the threshold value.
Claim 3
Dependent Claim
15 words
The system recited in claim 1, wherein the means for generating identifies the selected workstation.
Claim 4
Dependent Claim
22 words
The system recited in claim 2, wherein the means for selectively querying interrogates respective workstations to obtain workstation resident unused disk capacity.
Claim 5
Independent Claim
82 words
A method for managing memory capacity in a data processing network connected to communicate data in specified protocol between multiple workstations with resident nonvolatile memory devices, comprising the steps of: selectively querying a workstation connected on the network to determine the respective unused nonvolatile memory; comparing the determined unused nonvolatile memory to a respective minimum capacity threshold value; and generating event response data in the network to signify that the unused nonvolatile memory at the queried workstation is below the threshold value.
Claim 6
Independent Claim
82 words
A method for managing memory capacity in a data processing network connected to communicate data in specified protocol between multiple workstations with resident nonvolatile memory devices, comprising the steps of: selectively querying a workstation connected on the network to determine the respective unused nonvolatile memory; comparing the determined unused nonvolatile memory to a respective minimum capacity threshold value; and generating event response data in the network to signify that the unused nonvolatile memory at the queried workstation is below the threshold value.
Claim 7
Dependent Claim
18 words
The process recited in claim 4, wherein the generated event response identifies the selected workstation within the network.
Claim 8
Dependent Claim
21 words
The process recited in claim 5, wherein the generated event response is transmitted from the selected workstation to a network log.
Claim 9
Dependent Claim
22 words
The process recited in claim 6, wherein the query retrieves and logs workstation resident unused disk capacity information from the selected workstation.
Claim 10
Dependent Claim
26 words
The process recited in claim 6, wherein the generated event response causes an allocation of workstation resident nonvolatile memory within the network to the selected workstation.
Claim 11
Dependent Claim
13 words
The process recited in claim 4, wherein the selected query is periodically enabled.
Claim 12
Dependent Claim
27 words
The process recited in claim 9, wherein the selection is controlled by a workstation other than the one subject to the query or by a host computer.
Claim 13
Dependent Claim
17 words
The process recited in claim 10, wherein the generated event identifies the selected workstation within the network.
Claim 14
Dependent Claim
21 words
The process recited in claim 11, wherein the generated event response is transmitted from the selected workstation to a network log.
Claim 15
Dependent Claim
22 words
The process recited in claim 12, wherein the query retrieves and logs workstation resident unused disk capacity information from the selected workstation.
Claim 16
Dependent Claim
26 words
The process recited in claim 11, wherein the generated event response causes an allocation of workstation resident nonvolatile memory within the network to the selected workstation.
