Methods and apparatus for management of data storage resources
First Claim
1. A document storage and retrieval system for storage and retrieval of document images, comprising:
- a storage center including one or more data storage units, at least one data storage unit employing removable storage media;
a storage server for controlling said removable storage media, the storage server being operative to receive data storage and retrieval commands and to write data to and read data from the one or more data storage units in accordance with the commands, the storage server being operative to maintain a storage transaction database for storing data relating to completed storage and retrieval transactions and a storage status database for storing data relating to contents and usage of each data storage unit, as well as a pending request queue for storing pending storage and retrieval commands and data related thereto; and
a storage and retrieval monitor for examining the storage transaction database, the storage status database and the pending request queue in order to generate usage information for presentation to a user, the usage information including usage trend information indicating a rate at which storage capacity of said removable storage media is being filled and a projections indicating when said removable storage media will need to be removed and replaced.

Abstract
Techniques for monitoring of storage usage and trends in a document image processing and storage system are described. A storage and retrieval monitor resides on a storage server and monitors the status of volumes and units on which data is stored, completed storage requests and pending storage and retrieval requests. The storage and retrieval monitor analyzes completed and pending storage requests in order to project usage trends over time, and also analyzes the storage status in order to determine the used and available space and the space dedicated to various units and classes of data such as documents and families of documents. The storage and retrieval monitor generates alerts when the available storage space falls below a predetermined limit. The alerts and the usage and status information are presented to a user through a user interface allowing easy access to the storage and usage information and the ability to select desired information for display.

9. A method of monitoring of usage of data storage capacity in a document storage and retrieval system, comprising the steps of:
-
collecting and storing completed transaction information relating to the results of data storage and retrieval commands for writing to and reading from a plurality of data storage units employing removable storage media; collecting and storing pending request information relating to data storage and retrieval commands that have been queued for execution for writing to and reading from the data storage units; examining and analyzing storage status information for the data storage units in order to determine the used and available capacity of the data storage units; examining and analyzing the completed transaction information and the pending request information together with the storage status information in order to generate usage trend information relating to projected usage and capacity of the data storage units; and formatting the storage status information and the usage trend information to provide an overview of present and projected usage of the data units and presenting the storage status information and the usage trend information for display. - View Dependent Claims (10, 11, 12)
