    • Aspects of the present invention provide a method of specifying a device driver design for a board device. The method includes receiving a board device with various functional elements and on-board storage to be operatively coupled to a computing device through an interconnect. The device driver design is specified through the identification of one or more device driver parameters. The device driver parameters are to be used subsequently to customize an adaptive device driver that interfaces with the board device and each of the one or more functional elements. Device driver parameters are stored in a predetermined storage construct allocated from the board device. These device driver parameters remain stored in the storage construct until there is a need for the board device and corresponding device driver. Customizing the adaptive device driver is done after the device driver parameters have been stored and typically when a computer device starts or ‘boots”. Initially, aspects of the present invention may receive an indication that a board device and one or more functional elements associated with the board device have been attached to an interconnect and requires a device driver. Next, aspect of the present invention retrieve device driver parameters from the storage constructs and customizes the adaptable device driver into a device driver for the board device in accordance with the device driver parameters.
    • 本发明的方面提供了一种用于指定板设备的设备驱动程序设计的方法。 该方法包括接收具有各种功能元件和板载存储器的板设备,以通过互连可操作地耦合到计算设备。 通过识别一个或多个设备驱动程序参数来指定设备驱动程序设计。 随后将使用设备驱动器参数来定制与板设备和一个或多个功能元件中的每一个接口的自适应设备驱动器。 设备驱动器参数被存储在从板设备分配的预定存储结构中。 这些设备驱动程序参数保存在存储结构中,直到需要板卡设备和相应的设备驱动程序为止。 自定义自适应设备驱动程序是在存储设备驱动程序参数后通常在计算机设备启动或启动时完成的。 最初,本发明的各方面可以接收指示,即板单元和与该板设备相关联的一个或多个功能单元已被附接到互连并且需要设备驱动程序。 接下来,本发明的方面从存储结构检索设备驱动程序参数,并根据设备驱动程序参数将可适应设备驱动程序定制成用于板设备的设备驱动程序。

    • This invention provides a specified retention date within a data set that is locked against deletion or modification within a WORM storage implementation. This retention date scheme does not utilize any proprietary application program interfaces (APIs) or protocols, but rather, employs native functionality within conventional file (or other data containers, data sets or block-based logical unit numbers) properties available in commonly used operating systems. In an illustrative embodiment, the retention date/time is calculated by querying the file's last-modified time prior to commit, adding the retention period to this value and thereby deriving a retention date after which the file can be released from WORM. Prior to commit, the computed retention date is stored in the file's “last access time” property/attribute field, or another metadata field that remains permanently associated with the file and that, in being used for retention date, does not interfere with file management in a WORM state. Since this field is not utilized in a WORM context, it can be adapted to store this date. Once stored, the retention date in this field is locked against modification. Where extension (never reduction) of a retention period is desired, the last access time field be updated, wherein the new retention period is added to the existing last access time value to derive a new, later retention date for the file. Upon expiry of the retention date, the system allows deletion of the expired WORM file/data set.
    • 本发明提供在WORM存储实现中锁定以防止删除或修改的数据集内的指定保留日期。 此保留日期方案不使用任何专有的应用程序接口(API)或协议,而是在常用文件(或其他数据容器,数据集或基于块的逻辑单元编号)中使用常规操作系统中可用的属性的本机功能 。 在说明性实施例中,通过在提交之前查询文件的最后修改时间来计算保留日期/时间,将保留期间添加到该值,从而导出可以从WORM释放该文件的保留日期。 在提交之前,计算的保留日期存储在文件的“最后访问时间”属性/属性字段中,或与文件永久关联的另一个元数据字段,并且在用于保留日期时不会干扰文件管理 在WORM状态。 由于这个字段在WORM上下文中没有被使用,所以它可以适应于存储这个日期。 一旦存储,此字段中的保留日期将被锁定以防修改。 在期望保留期限的延长(永不减少)的情况下,最后访问时间字段被更新,其中新的保留期被添加到现有的最后访问时间值以导出该文件的新的较后的保留日期。 保留期限届满后,系统允许删除过期的WORM文件/数据集。
