摘要： In a multi-processor system, each processor has a respective hard affinity queue and soft affinity queue. For execution of a thread, a queue loader places an instance of the thread upon the hard or soft affinity queue of a selected processor. The selection may use an affinity attribute, processor attribute, accessor function, or a respective program of code threads for each processor. A thread instance on a processor's hard affinity queue is executed only by that processor. A thread instance on a processor's soft affinity queue is executed by that processor unless another processor has a soft affinity queue empty of thread instances ready for execution. Each processor alternates service priority between its hard and soft affinity queues. When a thread has a soft affinity it is initially bound to the processor it is started from. It will, then, be bound to the last processor it has been run on.

摘要： In a network attached cached disk storage system, data is transmitted over the network in data packets having a data length that is much smaller than the logical block size for reading or writing to disk storage. To avoid copying of data from network port buffers to the cache memory, the cache blocks of the cache memory are organized as linked lists of list elements, which can be used as network port input or output buffers. For TCP data packets, for example, each list element has a data slot for storing up to 1,500 bytes, and a field indicating the number of bytes stored in the data slot.

摘要： Directory attributes are provided so that the time for creating an incremental backup of a file system by a scan of the file system tree is proportional generally to the number of files that change between backups instead of the number of files in the file system. A tree modification attribute indicates whether or not any file in a directory tree has changed since the last backup. If no file has changed in the directory tree, then the entire tree is skipped during the scan for changed files. In addition, a list is compiled of the files in the directory that represent branches having at least one changed file, so that the list is scanned instead of the directory entries. When a file is changed for the first time since the last backup, the file is queued so that the directory attributes are updated in a background process.
摘要翻译：提供目录属性，以便通过文件系统树的扫描来创建文件系统的增量备份的时间通常与备份之间而不是文件系统中的文件数量的文件数量成比例。树修改属性指示自上次备份以来目录树中的任何文件是否已更改。如果目录树中没有文件已更改，则在扫描更改的文件期间将跳过整个树。另外，编译目录中表示具有至少一个已更改文件的分支的文件的列表，以便扫描列表而不是目录条目。当文件自上次备份以来首次更改文件时，文件将排队，以便在后台进程中更新目录属性。

摘要： A method is used in managing global data caches for file systems. Space is allocated in a volatile memory of a data storage system to a global data cache that is configured to store a set of data objects for a plurality of different file systems. The set of data objects is accessed by the plurality of different file systems. Contents of a file of a file system are stored in a data object in the global data cache upon receiving a write I/O request for the file. A copy of the data object and information for the data object are stored in a persistent journal that is stored in a non-volatile memory of the data storage system. Contents of the file are updated on a storage device based on the data object stored in the global data cache and information stored in the persistent journal.

摘要： A method is used in managing accesses to active-active mapped logical volumes. A portion of a mapped logical volume associated with an I/O request is determined. Based on the determination, a set of storage processor paths for accessing the mapped logical volume is determined.

摘要： A method is used in managing snapshot in cache-based storage systems. A request to create a snapshot of a data object is received. A portion of the data object is cached in a global cache. The data object is associated with a mapping object. The mapping object manages access to the portion of the data object. A snapshot of the data object is created. A snapshot mapping object is associated with the snapshot of the data object. The snapshot mapping object includes a link to the mapping object. The snapshot mapping object is a version of the mapping object and shares the portion of the data object cached in the global cache.

摘要： When a client requests creation of a production file system or logical unit number (LUN) of storage, a sparse metavolume and a container file system built on the sparse metavolume are implicitly created for containing the production file system or LUN. By implicitly creating one container file system for each production file system or LUN, it is possible to hide the management of the container file system from the client or end user. The creation of snapshot copies in the container file system can also be hidden from the client or end user. Customer service level expectations and thin provisioning can be met automatically by storage policies implemented upon the container file system and the underlying sparse metavolume.

摘要： The present invention augments each entry in a memory frame table to include information associated with the availability of any page that is buffer cache allocated. The availability information may include, for example, a link to a buffer cache descriptor associated with a buffer cache allocated page. Alternatively, the availability information may include a use status of the buffer cache allocated page. During a consecutive multi-page allocation process, pages which are buffer cache allocated are checked for availability. Should a buffer cache allocated page be available for use, it is intelligently pre-empted by the allocation process. By providing a mechanism to readily determine buffer cache page availability, a multi-page allocation process with increased efficiency may make intelligent decisions about the appropriateness of buffer cache page pre-emption.

摘要： A method is used in managing updating of metadata of file systems. A reference to a change to metadata of a file of a file system is stored in a global sync list configured to store changes to metadata of a plurality of files of a plurality of file systems. The change to the metadata of the file is stored in a journal upon receiving an I/O request for the file of the file system. The journal includes metadata transactions upon the plurality of files of the plurality of the file system. The change to the metadata of the file of the file system is applied to metadata of the file system organized on a storage device using the reference to the change stored in the global sync list.

摘要： For enabling a fast reverse lookup of parent directories storing records of hard links to a specified regular file, a file system manager maintains a hard link database (HLDB) storing information for addressing hard links to the regular files having multiple hard links. The HLDB contains a corresponding HLDB file for each regular file having multiple hard links. In a preferred implementation, the inode of each regular file stores the addressing information for one hard link to the regular file, a corresponding HLDB file stores the addressing information for other hard links to the regular file, each HLDB file is a directory accessed by invoking file system manager directory access routines, and the HLDB has a directory tree providing a multi-level hash index for searching the HLDB given the inode number of a regular file.
