摘要： According to one embodiment, in response to a request for verifying a first prime representing a consistent point of a file system of a storage system having a plurality of storage units, each of a plurality of prime segments collectively representing the first prime is examined to determine whether the corresponding prime segment has been previously verified. Each of the prime segments is stored in one of the storage units, respectively. At least a first of the prime segments that has not been previously verified is verified, without verifying a second of the prime segments that has been previously verified. The first prime, when at least the first prime segment has been successfully verified, can be used to construct the consistent point of the file system.

摘要： Techniques for managing data objects of a data storage system are described herein. According to one embodiment, a hash function is generated for a plurality of data objects by analyzing each of the data objects stored in the data storage system. For each of the data objects, a hash operation is performed on the data object using the hash function, generating a hash value. The hash value is associated with a predetermined attribute of the data object, such that the predetermined attribute of the data object is uniquely identified using the hash function subsequently in response to a request for accessing the predetermined attribute of the data object. The data object is then stored at a persistent storage location of the data storage system, wherein the persistent storage location is identifiable based on a hash value obtained from the hash function.
摘要翻译：本文描述了用于管理数据存储系统的数据对象的技术。根据一个实施例，通过分析存储在数据存储系统中的每个数据对象，为多个数据对象生成散列函数。对于每个数据对象，使用散列函数对数据对象执行散列操作，生成散列值。散列值与数据对象的预定属性相关联，使得随后响应于访问数据对象的预定属性的请求，使用散列函数唯一地识别数据对象的预定属性。然后将数据对象存储在数据存储系统的持久存储位置，其中基于从散列函数获得的散列值可以识别持久存储位置。

摘要： According to one embodiment, a file system (FS) of a storage system is partitioned into a plurality of FS partitions, where each FS partition stores segments of data files. In response to an input and output (IO) request for accessing a first of the FS partitions, a second of the FS partitions is selected that is currently in a ready state for access. The second FS partition is then removed from the ready state for access. The first FS partition is brought into a ready state for access.

摘要： Techniques for providing write-once-read-many (WORM) storage are described herein. According to one embodiment, a range of values is received to set an attribute of a file, where the received range of values is outside of an ordinary range of the attribute in accordance with a file system associated with the file. In addition, a management action is received to be associated with the received range of values of the attribute, where the management action is unrelated to an ordinary action associated with the attribute of the file in accordance with the file system. In response, the received management action is associated with the received range of values of the attribute. Other methods and apparatuses are also described.

摘要： Techniques for data migration of a storage system are described herein. According to one embodiment, for at least one of segments of a file to be migrated from a source storage tier to a target storage tier, a fingerprint of the segment is transmitted to the target storage tier. In response to a response received from the target storage tier indicating that the segment has not been stored in the target tier based on the fingerprint, a storage space of the target tier estimated for migrating the file is incremented. One or more segments of the file that have not been stored in the target tier are migrated if the one or more segments of the file fit in the target storage tier based on the estimated storage space of the target tier.

摘要： A system and method of offline annotation of future access are disclosed. According to one embodiment, a request is received at a storage system to read a portion of a file stored in the storage system. In response to the request, chunks of the file are cached in a cache memory of the storage system. In response to a request for cache space reclamation, the system then determines future request to the file based in part on a next access auxiliary table (NAAT) associated with the file, which was created prior to receiving the request to read and stored in a persistent storage location of the storage system. Based on the determination, the system evicts from the cache memory at least one chunk of a read unit (RU) whose next access is a furthest among the cached chunks.

摘要： Techniques for committing data objects to be immutable are described herein. According to one embodiment, in response to a request received through an interface of a storage system, the request being associated with a data object stored in the storage system, it is determined whether the data object should be committed to be immutable. The data object is committed to be immutable if it is determined that the data object should be committed to be immutable. Thereafter, an action associated with the request is performed, where the action is performed dependent upon whether the data object is immutable. Other methods and apparatuses are also described.
