摘要： Data of a global file system spread over multiple local NAS systems may be consolidated as a copy into a single remote NAS system. When remote copy is set up, the local NAS systems replace referrals within the global file system with directories and send these in place of the referrals to the remote NAS system. Then, other local NAS systems referred to by the referrals send files and directories under the directories replacing the referrals on the remote NAS system. Alternatively, to split copy data of a locally-stored global file system amongst multiple remote NAS systems, the local NAS system replaces specified directories with referrals, and sends the referrals with the data to one of the remote NAS systems. Then, the local NAS system sends files and directories under the directories replaced with referrals to one or more other remote NAS systems as referred to by the referrals.

摘要： A system for managing clock adjustment in a storage system is provided. The system includes a clock configured to provide a current time, wherein the current time is used to enforce a content retention period, a memory configured to store clock management information, wherein the clock management information includes a last adjustment time and a number of maximum adjustable time ranges, wherein the last adjustment time represents the time which the clock was last adjusted, and a storage access program. The storage access program is configured to receive a proposed new time for the clock, determine whether the proposed new time is reasonable using the current time, the last adjustment time and a specific range selected from the maximum adjustable time ranges, and adjust the current time of the clock to the proposed new time if it is determined that the proposed new time is reasonable. The storage access program is further configured to prevent adjustment of the clock to the proposed new time if it is determined that the proposed new time is unreasonable.

摘要： A hierarchical storage system comprises a host computer and a storage system. The storage system comprises at lease two kinds of storage devices, a first tier storage and a second tier storage. The first tier storage is a high performance (or high cost) storage device, and the second tier storage is a lower performance (or lower cost) storage device. The storage system creates a virtual volume based on the first and second tier storages, and enables the host computer to access the virtual volume. A file system in the host computer knows which region of the virtual volume corresponds to the first tier storage and which region of the virtual volume corresponds to the second tier storage. When the file system receives a command to migrate a file from the first tier to the second tier storage, e.g., from a user, the file system examines the address information of the virtual volume where the file resides, and instructs the storage system to migrate the blocks of the designated addresses.

摘要： An apparatus, system, and method enable access to a storage system by distinguishing SCSI Object-Based Storage Device Commands (OSD) commands from block-based SCSI commands on the same port and storage subsystem. The storage subsystem has the capability of identifying the storage protocol from a corresponding command, and processes the command accordingly for a storage device formatted for use with the respective storage protocol. This way, a storage subsystem can consolidate data from several dedicated command ports to a single physical port, while also enabling a single storage system to store and provide access to data in multiple different storage protocol formats.
摘要翻译：装置，系统和方法通过在同一端口和存储子系统上区分基于块的SCSI命令的基于SCSI对象的存储设备命令（OSD）命令来实现对存储系统的访问。存储子系统具有从对应命令中识别存储协议的能力，并相应地处理用于与各自存储协议一起使用的格式化的存储设备的命令。这样一来，存储子系统就可以将数据从多个专用命令端口合并到单个物理端口，同时还可以使单个存储系统存储和提供对多种不同存储协议格式的数据的访问。

摘要： A method and apparatus for placing objects on a storage device of a storage system and reconstructing data of objects in the storage device. The storage system stores data as objects and implements a RAID architecture including a plurality of the storage devices, and a disk controller for processing Object-based Storage Device (OSD) commands. Each object includes data and attribute. Parity data is calculated for reconstructing an object upon occurrence of a storage device failure. Each storage device includes plural stripes each having a predetermined length. Each object is stored in a stripe wherein an attribute is stored in the head of the stripe and data is stored after the attribute. When the object size exceeds the stripe length, the remainder of the object is stored in the next stripe, and when another object is to be stored, an attribute is stored at a head of a further next stripe and data is stored just after the attribute.

摘要： A data migration system is provided for migrating data between an existing file server apparatus and a new file server apparatus in a computer system that includes a plurality of host computers and a plurality of file server apparatuses that are mutually connected to one another. The data migration system on the new file server apparatus copies file attributes unique to the network attached storage (NFS) and file attributes unique to the common internet file system (CIFS) from the existing file server apparatus, and stores the file attributes without changing the file attributes in the new file server apparatus. Then actual data is moved from the existing file server to the new file server. When a file access to data is made from a host computer during the file migration process, and if the data has not been migrated from the existing file server to the new file server, the data is read out from the existing file server onto the new file server, and the file access is processed by the new file server as if the existing file server were processing the file access.
摘要翻译：提供了一种数据迁移系统，用于在包括彼此相互连接的多个主机计算机和多个文件服务器装置的计算机系统中的现有文件服务器装置和新文件服务器装置之间迁移数据。新文件服务器装置上的数据迁移系统从现有文件服务器装置复制网络连接存储（NFS）所特有的文件属性以及普通网络文件系统（CIFS）特有的文件属性，并存储文件属性而不改变新文件服务器设备中的文件属性。然后将实际数据从现有文件服务器移动到新的文件服务器。当在文件迁移过程中从主机进行文件访问数据时，如果数据尚未从现有文件服务器迁移到新文件服务器，则将数据从现有文件服务器读取到新的文件服务器上文件服务器，文件访问由新文件服务器处理，就好像现有文件服务器正在处理文件访问一样。

摘要： A storage system conducting remote copy functions such that, when data is updated at a local site, contents of the update can be referred to in real time by storage at a remote site. A disk-control unit at a remote site receives file data written in accordance with an update of a file in a storage system at a local site and a history of the file-management information from the storage system at the local site and stores the data and the history. A file-system processing unit refers to the history and updates the file-management information in a file-system cache in accordance with the update of the file in the storage system at the local site. When a client issues a read request, the file-system processing unit refers to the file-management information updated in the file-system cache and transfers the contents of the update of the file to the client.

摘要： A system and method for object-level snapshot creation in an object-based storage system. The host device includes a first object management table (OMT) and a file system. The object-based storage system is connected to the host device and includes a controller and object-based storage devices (OSD). The controller includes a snapshot module, a second OMT. The snapshot module receives and processes OSD and other commands from the file system or a service processor, creates an original object and a mirror object in an OSD, and initiates a snapshot operation in an OSD. The first OMT may also reside at a metadata server. A snapshot operation may be a mirror operation or a copy on write operation. The first OMT and the second OMT maintain mapping information of a file identifier, a partition ID, and an object ID, and an object status and a generation number of snapshots.
