摘要： Multiple domains are created for processes of a storage server. The processes are capable of execution on a plurality of processors in the storage server. The domains include a first domain, which includes multiple threads that can execute processes in the first domain in parallel, to service data access requests. A data set managed by the storage server is logically divided into multiple subsets, and each of the subsets is assigned to exactly one of the threads in the first domain, for processing of data access requests directed to the data set.

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： 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.

摘要： A set of specially-configured LUT's are used in a rasterizing portion of a graphics system for simulating Sensor-assisted Perception of Terrain (SaPOT) so that simulation of the image produced by a given sensor can proceed rapidly and with good accuracy at a per-texel level of resolution. More specifically, terrain texels-defining memory is provided with a plurality of addressable texel records where each record contains: (a) one or more material identification fields (MID's); (b) one or more mixture fields (MIX's) for defining mixture proportions for the materials; and (c) slope-defining data for defining a surface slope or normal of the corresponding texel. A sky-map LUT is provided for simulating the act of looking up to the sky along the normal surface vector of a given texel to thereby obtain a reading of the sky's contribution of illumination to that terrain texel. A reflectance LUT is provided for simulating the act of reflecting filtered radiation (light) off the material surface of the given terrain texel to thereby obtain a reading of the amount of light that the surface of the texel will reflect. The reflectance and sky contribution factors are multiplied to obtain a per-texel signal representing the amount sensor-detectable light produced from each terrain texel. A generally similar approach is taken to determine what amount of sensor-detectable, black body radiation will be produced from each terrain texel. Each terrain texel is simulated as having a specifiable mixture of plural surface materials. Each terrain texel is allowed to be shadowed during different times and the per-texel shadowing is accounted for.

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.
摘要翻译：提供了一次多次写入（WORM）存储系统，该系统使用与文件服务器上的文件系统相关联的大容量且相对便宜的磁盘。文件系统包含大部分或全部所需的WORM功能，以便在客户端应用程序，客户端操作系统和开放式协议（如果需要）上施加最小的占用空间。系统围绕包含文件的WORM存储卷组织，当提交到WORM存储时，不能删除或修改。用于标识WORM卷中的文件的任何文件路径或目录树结构都被锁定，不能被删除。在一个实施例中，管理员创建能够存储指定的WORM文件的WORM卷。然后，客户端使用适当的协议语义创建一个适当的WORM文件。将文件写入卷并通过将文件属性从非只读状态转换为只读状态来提交。文件系统将WORM卷中任何文件的持久存储的WORM属性识别为WORM文件。此后，客户端，管理员或其他实体的任何修改文件属性，写入文件或删除文件的尝试都被拒绝，请求被拒绝的消息被返回给尝试方。

摘要： A technique for partially offloading, from a main cache in a storage server, the storage of cache tags for data blocks in a victim cache of the storage server, is described. The technique includes storing, in the main cache, a first subset of the cache tag information for each of the data blocks, and storing, in a victim cache of the storage server, a second subset of the cache tag information for each of the data blocks. This technique avoids the need to store the second subset of the cache tag information in the main cache.
