摘要： A technique provides an administrative path for accessing a writeable master storage volume in a mirrored storage environment. Illustratively, a writeable master storage volume stores a master set of data addressable by a corresponding pathname, and zero or more read-only (e.g., load-balancing) mirrored storage volumes are configured to store a mirrored set of the master set of data, the mirrored set also addressable by the corresponding pathname. Clients may read data from either the master storage volume or one of the mirrored storage volumes (e.g., according to a configured access location, such as a local mirrored volume if one exists) by issuing read requests having the corresponding pathnames. Also, each client may specifically access the master set of data from the master storage volume by issuing an access (e.g., read/write) request having a specified master storage volume pathname prefix prepended to the corresponding pathname.

摘要： A lightweight coherency control protocol ensures consistency of data containers, such as a file, and associated data buffers stored on one or more volumes served by a plurality of nodes, e.g., storage systems, connected as a cluster. Each data buffer is associated with a current cache sequence number comprising a load generation value and an update count value. The load generation value is incremented every time an inode of a file is loaded into a memory of the storage system. Once the inode is loaded and its load generation value is set, then the appropriate buffer of a buffer tree for the file is loaded into the memory. The update count value is incremented each time the buffer is updated with a write request/operation. Therefore, each buffer loaded into memory is tagged with the load generation value and an update count from the time that buffer is loaded.
摘要翻译：轻量级一致性控制协议确保数据容器（例如文件）和存储在由作为集群连接的多个节点（例如存储系统）所服务的一个或多个卷上的相关联的数据缓冲器的一致性。每个数据缓冲器与包括负载生成值和更新计数值的当前高速缓存序列号相关联。每当将文件的inode加载到存储系统的存储器中时，负载生成值将增加。一旦加载了inode并且设置了其负载生成值，则将该文件的缓冲树的适当缓冲区加载到内存中。每次使用写入请求/操作更新缓冲区时，更新计数值都会递增。因此，加载到内存中的每个缓冲区都会被加载负载生成值和缓冲区加载时的更新计数。

摘要： A system and method to allow a volume to appear in multiple locations in a super-namespace. A super-namespace is a hierarchy of namespaces within a storage system environment, such as a storage system cluster. The volume can appear in multiple locations in the super-namespace and/or in multiple namespaces within the super-namespace.

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： Techniques for caching media data, including streaming media data, using content-sensitive identifiers. The content-sensitive identifiers enable a caching proxy or a caching server to unambiguously determine the version or contents of media data cached by the caching proxy for a particular data pointer or data reference (e.g., a URL) such that an appropriate version of the media data can be served to a requesting client system in an efficient and economical manner.
