    摘要： 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.

    摘要： Method and system are provided for handling data when power failure from a primary power source of a storage system is detected. The system provides a first memory and a second memory. The first memory is primarily used to store data when the primary power source is operating. If a power failure is detected, a first indicator is set to indicate that data is stored or being transferred to the second memory. Thereafter, data is transferred from the first memory to the second memory. Any errors during the transfer are logged. Once power is restored, data is transferred back to the first memory. A second indicator is set to indicate that there is no data at the second memory.

    摘要： A system is provided to commit data to persistent storage. The system comprises a configuration component to set an autocommit period, a scanner to detect that the autocommit period has expired for a file and a commit component to commit the file to write once read many (WORM) status In one embodiment, when an autocommit period is set, the system may be configured to automatically commit a file to WORM status if the file has not been changed for the autocommit period.

    摘要： A write-once-read-many (WORM) storage system that employs large-capacity and relatively inexpensive disks in connection with a file system on a file server is provided. The file system contains most or all of the required WORM functionality so as to impose a minimal footprint on client applications, client operating systems and open protocols if desired. The system is organized around WORM storage volumes that contain files that, when committed to WORM storage, cannot be deleted or modified. Any file path or directory tree structure used to identify the file within the WORM volume is locked and cannot be deleted. In one embodiment, the administrator creates a WORM volume, capable of storing designated WORM files. The client then creates an appropriate WORM file using the appropriate protocol semantics. The file is written to the volume and committed by transitioning the file attributes from a not-read-only to a read-only state. The- file system recognizes the persistently stored WORM attribute of any file in a WORM volume as WORM file. Henceforth, any attempt to modify the file attributes, write to the file, or delete the file, by clients, administrators or other entities is rejected and a request denied message is returned to the attempting party

    摘要： Methods involve in-flight processing of inorganic particles synthesized within the flow. Thus, the flow extends from an inlet connected to a reactant delivery system with inorganic particle precursors to a collector. The as formed inorganic particle can be modified with radiation and/or the application of a coating composition. Additional processing steps can be introduced as desired. Suitable apparatuses for in-flight processing can be based on addition of processing elements onto an inorganic synthesis reactor, such as a laser pyrolysis reactor.

    摘要： A technique for sanitizing data storage devices, such as magnetic disks, is disclosed. Logical data storage units such as files or portions thereof may be individually deleted and sanitized on a disk. A disk is divided into physical disk regions, each comprising one or more blocks. The contents of the disk are encrypted using a separate encryption key for each physical disk region. If a file or other data structure located in a first disk region and encrypted using a first encryption key is to be deleted, the logical portions (i.e., blocks) of that region that do not belong to the file are re-encrypted using a second encryption key, and the first encryption key is deleted.
