Abstract: An interface for managing incremental data storage includes a write function that appends an entry to an incremental log, a read function that retrieves a most recent log entry corresponding to a block address, and a snapshot function that automatically partitions the incremental log into an additional volume. The interface may also include a policy assignment function that associates specified policies with explicitly or implicitly specified resources, a read entry function that retrieves sequential entries from the incremental log, and a compact volume function. The provided functions and associated apparatus, method, and system, facilitate management of incremental data including snapshot, remote copy, data compaction, policy management, data restoration, and other operations on data storage devices and systems.

Abstract: Components in a data storage subsystem are tracked, and their status monitored, with the use of memory devices such as RFID tags. In the practice of the invention, a component of a data storage subsystem, such as a data recording device, is associated with a memory device, such as but not limited to a Radio Frequency Identification (RFID) tag, that is capable of storing information regarding a status of the data storage component. A storage controller controls the data storage component. A reader/writer operably integrated into the storage controller, wherein the reader/writer is operable to be controlled by the storage controller to communicate in a wireless manner an update of the information within said memory device regarding the status said data storage component.

Abstract: A method is disclosed to implement data management protocols using a projector. The method provides first information comprising data and metadata to the projector, where that metadata comprises data management protocols for said first information. The method then determines by the projector if the data management protocols designate a time interval. If the data management protocols designate a time interval, then the method determines, by the projector, that time interval, the current time, and if the current time is within the time interval. If the current time is not within the time interval, then the method does not permit presentation of the first information using the projector. Alternatively, if the current time is within the time interval, then the method permits presentation of the first information using the projector.

Abstract: Components in a data storage subsystem are tracked, and their status monitored, with the use of memory devices such as RFID tags. In the practice of the invention, a component of a data storage subsystem, such as a data recording device, is associated with a memory device, such as but not limited to a Radio Frequency Identification (RFID) tag, that is capable of storing information regarding the data storage component and configured to transmit such information upon interrogation by a reader device. The memory device is coupled to an indicator device that is configured to selectively indicate information about the data storage component.

Abstract: A method is disclosed to authenticate a local interface for a network attached projector. The method provides a projector, an information storage medium comprising first information, and a communication link capable of communicating with the projector and with the information storage medium. The method defines access rights for the first information. Upon receiving a request for access to the first information from the projector, the method determines if the requestor has access rights to the first information. If the method determines that the requester has access rights to the first information, then the method provides the first information to the projector. Alternatively, if the method determines that the requestor does not have access rights to the first information, then the method denies access to the first information.

Abstract: A disk management server (“DMS”), to manage a remote storage device; a wireless communication network; and a mobile computer create a system for secure remote booting of a mobile computer's operating system. To facilitate access to remote boot code, a multiple connection disk management server utilizes a trusted connection to negotiate communication security and an untrusted connection for transferring data once communication security has been established. The trusted connection is established through a physically securable interface, such as a wired network or line-of-site wireless network, e.g., infrared. Successful negotiation of communication security produces a security key that can be utilized to secure information exchange over the untrusted network. The untrusted connection may utilize any standard wireless communication protocol such as IEEE 802.11b.

Abstract: A method and apparatus for providing high-density storage is disclosed. A plurality of storage devices is aggregated in a package. A package-level controller is coupled to a carrier housing holding a plurality of storage devices, wherein the package-level controller provides a RAID logical configuration at a package-level for the storage devices held in the carrier housing. A controller may also be provided for virtualizing the logical addresses as at least one aggregate volume to provide a layer of abstraction to the storage devices. The package may be inserted into a storage system designed to manage multiple packages.

Abstract: A method and apparatus for aggregating storage devices is disclosed. A package for providing high density storage uses a carrier housing for holding multiple storage devices proximate to one another and aligned in a row, and an access device, coupled to the carrier housing, aggregates the physical addresses of the storage devices into logical addresses and making the logical addresses available over a connection.

Abstract: Changes such as write operations on a replication source comprising a hierarchically-indexed file system and associated data store are tracked and aggregated over a point-in-time image replication interval and communicated to a replication target. The replication target receives the changes, conducts operations to make the changes on a target volume or portion thereof, and conducts a point-in-time image replication operation to synchronize the replication target with the replication source. In the present invention the advantages of replication techniques developed for log-structured file systems are provided to systems with conventional hierarchical file systems. The invention also facilitates maintaining point-in-time retrievable images of a volume or portion thereof on a target volume while reducing the bandwidth and processing burden associated with replication.
