System and methods for reporting storage utilization

A network management device for generating storage utilization reports in a managed information environment comprising:

• a utilization reporter operable to identify storage categories in a storage system, the storage categories corresponding to a hierarchy and indicative of different levels of demarcation of the storage within the storage system, the levels of demarcation defining a progression, each storage category inclusive of previous storage categories, the storage categories including physical storage, configured storage, allocated storage, logical volumes, file systems and used storage, the utilization reporter further operable to:
• compute, for each of the identified hierarchical storage categories, a storage configuration indicative of storage usage at that level each hierarchical storage category indicative of storage capacity reserved at that level, reserved storage being unavailable to other users of the storage;
• and
• compute, within each computed storage configuration, a storage allotment corresponding to used and available storage for the particular storage system, the storage on the storage system further subdividing the storage allotment into accessible storage, accessible with no volume group considerations and accessible with no file system/database, the accessible storage indicative of online storage capability, the storage allotment further comprising:
• allocated storage, the allocated storage reclaimable for use by another storage category;
• and
• allotted storage, the allotted storage employed for active data storage;
• a console display coupled to the utilization reporter and operable to present, for a plurality of the identified storage categories, the computed storage allotment, each level of demarcation of storage categories inclusive of previous levels of demarcation, the storage allotment indicative of consumed storage attributable to users for that level, the utilization reporter further operable to:
• compute, for each storage category, the storage quantity consumed within that category;
• display the total storage quantity, the consumed quantity and the available quantity for each of the storage categories
• identify storage areas of a storage array, the storage areas corresponding to user demand;
• and
• compute, for a plurality of storage categories, a trending analysis indicative of utilization of the storage quantity over time, the utilization indicative of the ratio of a consumed storage quantity to unused storage quantity for a storage area.

A method for generating storage utilization reports in a managed information environment comprising:

• identifying storage categories in a storage system, the storage categories indicative of levels of demarcation of a storage quantity within the level, each the storage categories indicative of a storage quantity attributable to storage consumers;
• computing, for each of the identified storage categories, a storage configuration indicative of consumed storage at that level, consumed storage being unavailable to other storage consumers;
• presenting, for each storage category, the computed storage configuration attributable to each of a plurality of the storage consumers, each level of demarcation of storage categories inclusive previous levels of demarcation, the storage configuration indicative of consumed storage attributable to each of the storage consumers for that level;
• presenting a selection of available storage categories and storage allotments within each of the storage categories, the storage categories indicative of a hierarchical structure of consumed storage on a storage device;
• subdividing the storage allotment into accessible storage, accessible with no volume group considerations and accessible with no file system/database, the accessible storage indicative of online storage capability;
• receiving a selection of fields indicative of the available storage categories and storage allotments for display as columns on a storage utilization report;
• computing, for each of the storage categories, the storage configuration corresponding to the storage allotment in each storage category, the storage allotment indicative of the used, available, and total storage within the particular storage category;
• and
• displaying, in a simultaneous manner, the computed storage configuration including the selected storage allotment in each of a plurality of the selected storage categories.

A computer program product having a computer readable storage medium operable to store computer program logic embodied in an encoded set of processor based instructions including computer program code encoded thereon for generating storage utilization reports in a managed information environment comprising:

• computer program code for identifying storage categories in a storage system, the storage categories corresponding to a hierarchy and indicative of different levels of demarcation of the storage within the storage system;
• computer program code for computing, for each of the identified hierarchical storage categories, a storage configuration indicative of storage usage at that level;
• computer program code for computing, within each computed storage configuration, a storage allotment corresponding to used and available storage for the particular storage system;
• and
• computer program code for presenting, for a plurality of the identified storage categories, the computed storage allotment, each level of demarcation of storage categories inclusive of previous levels of demarcation, the storage allotment indicative of consumed storage attributable to users for that level;
• and
• computer program code for subdividing the storage allotment into accessible storage, accessible with no volume group considerations and accessible with no file system/database, the accessible storage indicative of online storage capability.
