Provided are a computer program product, system, and method for considering input/output workload and space usage at a plurality of logical devices to select one of the logical devices to use to store an object. A determination is made of a logical device to store the object based on workload scores for each of the logical devices indicating a level of read and write access of objects in the logical device and space usage of the logical devices. The object is written to the determined logical device.

Considering input/output workload and space usage at a plurality of logical devices to select one of the logical devices to use to store an object

Provided are a computer program product, system, and method for deduplicating chunk digests received for chunks in objects in objects provided by clients to store in a storage. An index has chunk signatures calculated from chunks of data in the data objects in the storage. A transaction requests a shared lock for a chunk digest calculated from a chunk in an object to add to the storage. In response to not receiving the shared lock, the transaction is granted a shared lock to the chunk digest in wait mode. The transaction does not proceed until being granted the shared lock. In response to receiving the shared lock, a determination is made as to whether the chunk digest is in the index. A reference to the chunk data is provided for the object when the chunk digest is indicated in the index.

Disclosed are a system, a method, and an article of manufacture to provide for the use of a global positioning system (GPS) to provide location information for an automated data storage library. One or more GPS antennas and receivers are coupled to an automated data storage library to enable quick and accurate location information for the automated data storage library. The location information may be used to determine the physical location of the automated data storage library. The GPS antennas may also be attached to one or more library frames in the automated data storage library to enable accurate location information for each frame. The GPS antennas are attached to one or more accessors or one or more drive canisters to provide accurate location information for each component.

A method and apparatus are provided for managing logging data communications in a computer system. The computer system is configured with a proxy agent in communication with a client machine and storage, and an embedded agent in communication with the proxy agent and the client machine. All inbound communications from the client machine to the storage are maintained in a log local to the proxy agent. However, all outbound communications are split between two different communications paths, with one outbound path from the storage directly to the client machine and a second outbound path from the storage to the client machine via the proxy agent. One of the two outbound paths is selected based upon one or more of the characteristics of the associated communication.

Audit logging and role based security using one way proxy architecture

An information technology (IT) environment includes IT managed resources in which the resources are abstracted using a model. In response to determining that a request for information received from a client is non-optimal in terms of processing the request, a first hint can be constructed that indicates how future requests are to be formulated by the client so that they are more optimal in terms of processing the future requests. In response to determining that the information is internally structured non-optimally in terms of processing the request, a second hint can be constructed that indicates how the information is to be internally structured more optimally in terms of processing future requests. In response to determining that processing the request will be non-optimal, a third hint can be constructed relating to a characteristic that results in non-optimal processing of the request, and logged within a hint log for offline analysis.

A method to provide redundant accessor availabilty in an automated data storage library. The method provides a data storage and retrieval system comprising one or more data storage devices a robot accessor and a gripper. Either at the same time or at a later time, the user obtains a second gripper and/or a second accessor. The method allows selection and/or authorization for additional support from the second gripper and/or the second accessor upon request and authorization. The redundant accessor capabilities are provided on an honor system for payment for the additional capability, and/or uses a system for tracking the redundant accessor usage, and/or uses license keys or other controls that must be obtained prior to enabling redundant accessor capabilities.

Apparatus and method to provide redundant accessor availability

A method to change the IP address of a server from a remote operator station, where that server comprises an HTTP server having a first IP address, and where that server is capable of communicating with one or more remote operator stations. One of those remote operator stations submits to the server, using the first IP address, an IP address change request. That IP address change request includes discontinuing use of the first IP address and commencing use of a second IP address. After receipt of the IP address change request, the server generates an HTML page comprising an embedded applet, where that applet is capable of monitoring the TCP/IP connection between the remote operator station and the server. The server provides that HTML page/applet to the remote operator station. Thereafter, the remote operator station continuously displays the status of the IP address change request using the provided applet. After the IP address change request is completed, the remote operator station communicates with the server using the second IP address.

Apparatus and method to remotely change IP address of server

Disclosed are a system, a method, and article of manufacture to provide for managing data storage media to provide secure storage of the data storage media in an automated data storage library. A logical library partition vault is created in the automated data storage library that is not accessible by any host computer. Data storage media in the logical library partition vault may only be accessed by an operator using a secure means. The logical library partition vault may comprise various components of the automated data storage library by assigning storage shelves, service bays, data storage media, data storage drives or other library components to the logical library partition vault.

A system and method for generating access authorization in a secure manner. After establishing data communications, a product and product center exchange unique information for the independent generation of a valid access authorization by both the product and product center. The access authorization then allows a computer system associated with the product center to access the product for testing, diagnostics, etc. An added security feature invalidates the access authorization after a predetermined time period.

Automatic password configuration during error reporting

In a distributed system of modules in a network, each module having an associated processor node comprising a processing unit for operating the associated module. The processing unit comprises a processor interface for communication in the network; and nonvolatile memory for storing code for the processing unit for operating the associated module, and for storing backup code for at least one other processing unit of another processor node in the network, the backup code for operating an associated module of the another processor node. In response to a request, the processing unit supplies the backup code to a processor node to be used to restore the code for operating the module associated with the requesting processor node.
