According to an embodiment of the invention, a storage server management application (SSMA) includes scripting ability. The scripting ability allows functionality to be added to the SSMA by deploying scripting packages onto the SSMA. The packages may be written by a user having access to the SSMA, and deployed onto the SSMA without affecting the core functionality of the SSMA, and may be easily removed. One package allows a system administrator to monitor the configuration of storage servers monitored by the SSMA by comparing the current configuration of the filers to a standard configuration. Another package monitors best practices for redundant array of inexpensive disks (RAID) systems. Other packages may be added to the SSMA.

According to an embodiment of the invention, a filer or other storage server is coupled to a network to store files for users of the network. Agents are coupled to the filer, and performs a scan or file walk for a Multi-Appliance Management Application (MMA) which is coupled to the filer and can monitor and manage the filer. A directory structure of the filer may be divided into two or more paths, each of which may be scanned by an independent agent. The results of the scan, or file walk, are saved to a database server. In this way, multiple agents may be used to scan a single storage server, and the amount of time required for the scan is reduced.

Segmentation of characters in a character set (10), made by placing a dark mark against a light background (12), is accomplished by establishing a vertical pixel projection for each pixel column in the image. The vertical pixel projections are filtered with a decay parameter so those pixel columns which contain only background have the highest projection. Thereafter, a set of "cut-points" (points of image segmentation) is obtained so that each cut-point coincides with a pixel column whose vertical pixel projection is both a local maxima and exceeds a predetermined threshold. The number of such cut-points is counted and if the number is not significantly greater than a predetermined number, the image is segmented along the cut-points. Otherwise, the vertical projections of those pixel columns coincident with the cut-points are filtered with a decreasing threshold to reduce the number of potential cut-points.

A method, apparatus, and system are described herein, in which system resources and operations are assigned to roles in a role-based access control system, and the roles are assigned to a plurality of users. An RBAC system is used to resolve the client request to perform an operation on a resource, the RBAC system using a hierarchy of the plurality of resources to determine if a user is permitted to perform the operation on a parent of the resource in the hierarchy of resources. The RBAC system also determines if a user is permitted to perform the operation on the resource if a user group to which the user belongs to has the required access.

Methods and systems are provided for managing electrical power consumption in a mobile phone or other portable communications device having a battery and a display. A series of views forming a flow are retrieved from a memory or other digital storage device for presentation on the display. For each of the views in the flow, performance information relating to the portable communications device is determined while the view is displayed, and this information is stored in the digital storage medium. Upon subsequent retrieval of each view from the digital storage medium, configuring the operation of the portable communications device in response to the stored performance information to thereby manage the electrical power consumption of the portable communications device.

According to an embodiment of the invention, a directory on a storage server is scanned. A number of children of the directory is determined, and the number is added to a reference count. A child is scanned to collect information about the child, and the information is combined into a summary of the directory. After the child is scanned, the reference count is reduced by one. According to another embodiment of the invention, the storage server is scanned by an agent separate from the storage server.

A method, apparatus, and system for providing role-based access control (RBAC) for storage management are described herein. Resource-identifying information is stored in a role-based access database for a network storage system, in association with role-identifying information for each of a plurality of roles and operation-identifying information. The operation-identifying information indicates one or more authorized operations for each of the plurality of roles and the resource-identifying information identifies specific resources maintained by the network storage system. The role-identifying information, data indicating one or more authorized operations for at least one of the roles, and resource-specific identifying information in the role-based access database are used to determine whether to allow or deny a request from a network storage client to access a resource maintained by the network storage system.

The invention provides for a skimmer (10) interconnected to the floating roof (30) of a floating roof tank (300) wherein a mixture of at least two immiscible liquids, including a lowest specific gravity liquid (50) and at least one higher specific gravity liquid (40), are stored. The skimmer (10) of the present invention is placed on the underside (20) of the floating roof (30). A funnel (140) is attached to the underside (20) of the roof (30) to extend downwardly into the liquid mixture wherein the funnel (140) has formed perforations (500) near the attachment of the funnel (140) to the underside (20) of the roof (30). A float (110) is operatively connected to the funnel (140) and selectively closes over the perforations (500) when the float (110) is in the higher specific gravity liquids (40) and opens over the perforations when the float (110) is disposed in the lowest specific gravity liquid (50 ).
