The terms sheet is selectively stored in the storage area and includes printed terms for the account. Associated packages and method are also disclosed.

Abstract: In response to read and write requests for data blocks at logical storage locations, a block mapping device determines physical storage locations on the storage devices. Read requests switch over secondary storage devices to the active mode when they are in the passive mode. Write requests write data blocks only to the primary storage devices. Secondary storage devices that have not been accessed for a minimum activation time may be switched over from the active to the passive mode to save power consumption and cooling. Data migration and data recall policies control moving of data blocks between the primary and secondary storage devices and are primarily based on threshold values.

Abstract: A method of constructing a retail display system includes creating a first display article including a support panel and hanging the first display article. Creating the first display article includes editing an original photograph of a clothing product for sale to appear similar to a mannequin wearing the clothing product for sale in an edited photograph. Hanging the first display article includes hanging the first display article in a display area using a mounting bracket secured to a back surface of the support panel. The method further includes positioning a retail good corresponding to the clothing product depicted in the photograph in proximity to the first display article. Retail display systems and methods of construction provide additional advantages.

Abstract: A retail product assembly includes a retail product, a bracket coupled thereto and defining an opening between the retail product and the bracket, and a hanger. The hanger includes a hanging portion configured to receive a support structure, a cross bar, a drop portion, and a tapered portion. The cross bar extends from the hanging portion and is wider than the bracket. At least a portion of the cross bar extends below the topmost sidewall of the retail product. The drop portion extends through the opening. The tapered portion extends away from the drop portion and is configured to slide through the opening to position a top edge of the tapered portion opposite the cross bar relative to the opening. The top edge of the tapered portion interacts with the bracket to support the retail product via the bracket when the hanger is hung from the support structure.

Abstract: A method for operating a storage system, including storing data redundantly in the system and measuring respective queue lengths of input/output requests to operational elements of the system. The queue lengths are compared to an average queue length to determine respective performances of the operational elements of the storage system.

An indication of the under-performing operational element is provided to host interfaces in the storage system. One of the host interfaces receives requests for specified items of the data directed to the under-performing element, and in response to the indication, some of the requests are diverted from the under-performing operational element to one or more other operational elements of the storage system that are configured to provide the specified items of the data.

The processor may be adapted to trigger an action that may be effective for managing the SSP in response to the amount of storage resources used for storing snapshots in the SSP crossing the threshold.

Abstract: A method for data storage, including configuring a first logical volume on a first storage system and a second logical volume on a second storage system. The second logical volume is configured as a mirror of the first logical volume, so that the first and second logical volumes form a single logical mirrored volume. The method also includes receiving at the second storage system a command submitted by a host to write data to the logical mirrored volume, and transferring the command from the second storage system to the first storage system without writing the data to the second logical volume. On receipt of the command at the first storage system, the data is written to the first logical volume. Subsequent to writing the data to the first logical volume, the data is mirrored on the second logical volume.

Abstract: A replication synchronization table (RST) is configured for the source instance. The RST is adapted for recording compacted information for at least one of a truncate and an erase operation applied on the source instance. The RST of the source instance is updated at a source component with the compacted information. The updated RST is transmitted from the source instance to the replicated instance. Based on the RST of the source instance and the RST of the replicated instance, data representative of a most recent position on the source component from which data should be transmitted to a replicated component to achieve a full synchronization is determined.

Abstract: Methods, systems, and computer programs are provided for failover responses to configuration node failures in SVC clusters. An SVC cluster manages a plurality of storage devices and includes a plurality of SVCs interconnected via a network, each SVC acting as a separate node.

The new configuration node sends storage device events to clients who have subscribed to this information according to subscription information obtained. The storage device is not installed in the original configuration node.
