Abstract:
Provided are a method, system, and program for writing data in a tape medium having wraps. A layout of the tape is provided including at least one segment within a full available length of a first set of wraps for writing user data and at least one segment within a full length of a second set of wraps for writing a work copy of the user data. User data is received to write to the tape medium and detecting is performed as to whether the data being written is occurring in a specified write mode. If the data writing is not occurring in the specified write mode, then writing the received user data to one segment in the first set of wraps. If the data writing is occurring in the specified write mode, then writing a work copy to available full length wraps not having user data.
Abstract:
A system facilitates the, procurement of one or more document services for a document directly from a document preparation software application used to create the document. The system activates a graphical user interface within the document preparation software application, contacts a server to identify available document services, and configures the graphical user interface based on the available document services. The system detects selection of one of the available document services and provides the document from the document preparation software application to one or more service providers for performance of the selected document service.
Abstract:
A method, system, and apparatus for re-conveying input/output (I/O) operations utilizing a sequential-access data storage device secondary communication port are disclosed. In accordance with one embodiment, a method is provided which comprises receiving an input/output (I/O) operation request via a first communication port of a primary data storage device, processing the I/O operation request utilizing the primary data storage device, and re-conveying the I/O operation request to a secondary data storage device substantially simultaneously with the processing via a second communication port of the primary data storage device. In the described embodiment, the primary data storage device comprises a sequential-access data storage device.
Abstract:
A method, system, and apparatus for dynamically validating a data encryption operation are disclosed. In one embodiment, a method is provided which comprises decrypting a first sequential data element of a plurality of data elements substantially in parallel with the encryption of a second sequential data element of the plurality, where the first element comprises first data and first encryption validation metadata. In response to the decryption, second encryption validation metadata is generated utilizing the first data. Thereafter, a determination is made whether the first element has been validly encrypted based upon a comparison of the first and second metadata. In other embodiments, an encryption validation indicator may be generated (e.g., to notify a user of a detected encryption error and/or to mark a portion of data for re-encryption), further encryption operations may be suspended, and/or the storage of the first data element may be controlled following such a determination.
Abstract:
A system and method for performing a search operation within a sequential access data storage subsystem are disclosed. According to one embodiment, a data storage subsystem is provided which comprises a search module and a communication channel interface to communicatively couple the data storage subsystem to a host data processing system via a communication channel. In the described embodiment, the search module is configured to receive search attribute data from the host data processing system via the communication channel interface, where the search attribute data specifies a search attribute. The search module is further configured to perform a search operation on data of a sequential access storage element utilizing the search attribute and to provide search result data to the host data processing system via the communication channel interface in response to a performance of the search operation.
Abstract:
Methods, apparatus and computer program products are provided to monitor and report performance data of a device such as a data storage drive. A plurality of quantitative values are obtained from feedback and measurement mechanisms in a data storage device of a first model during operation of the storage device. The plurality of quantitative values are normalized. Then, one or more qualitative values are generated from one or more normalized quantitative values and evaluated against corresponding baseline performance values established for the first model.
Abstract:
A magnetic tape cartridge, a recording system, and a magnetic tape drive are configured to, for example, guard against tampering with a write once overwrite protection pointer which allows a rewritable magnetic tape to be treated as write once. In one embodiment, the magnetic tape cartridge comprises a magnetic tape and a cartridge memory. The magnetic tape is configured to provide at least one overwrite protection pointer, the overwrite protection pointer identifying data to be protected from being overwritten; and the cartridge memory is configured to provide the at least one overwrite protection pointer, the overwrite protection pointer identifying magnetic tape data to be protected from being overwritten.
Abstract:
An infusion beverage package includes a body portion having overlying layers of porous material that are joined to form at least one compartment for carrying infusion beverage product in addition to a weight that causes the body portion to sink in water. The compartment(s) may also carry an agent (e.g., sweetener) that imparts flavor characteristics into a solution during steeping of the infusion beverage product. The weight is preferably realized by a non-toxic, insoluble odorless, flavorless microwaveable material (e.g., ceramic material, porcelain material, and naturally-occurring rock material). Alternatively, the weight may be realized by a dissolvable agent such as a sweetener. A multi-compartment single bag design and dual-bag designs are illustrated.
Abstract:
Provided are a method, system, and article of manufacture for writing data in a tape medium having wraps. A layout of the tape is provided including at least one segment within a full length of first set of wraps for writing user data and at least one segment within a full length of a second set of wraps for writing a work copy of the user data. User data is received to write to the tape medium. Detection is made of whether data writing is occurring in a specified write mode. A work copy is written to available segments in the second set of wraps not having user data in response to the data writing occurring in the specified write mode.
