摘要： A data processing system includes host data processors, a data storage system including data storage shared among the host data processors, and a data switch coupling the host data processors to the data storage system. The data storage system has host adapter ports coupled to the data switch. The data switch is programmed for distributing block I/O requests from the host data processors over the operable host adapter ports for load balancing of the block I/O requests among the operable host adapter ports. The shared data storage can be a file system striped across RAID sets of disk drives for load balancing upon disk director ports of the data storage system. The data processing system can be expanded by adding more data storage systems, switches for the additional data storage systems, and switches for routing block I/O requests from the host processors to the data storage systems.

摘要： For enhanced access control, a client includes a token in each read or write command sent to a block storage device. The block storage device evaluates the token to determine whether or not read or write access is permitted at a specified logical block address. For example, the token is included in the logical block address field of a SCSI read or write command. The client may compute the token as a function of the logical block address of a data block to be accessed, or a metadata server may include the token in each block address of each extent reported to the client in response to a metadata request. For enhanced security, the token also is a function of a client identifier, a logical unit number, and access rights of the client to a particular extent of file system data blocks.
摘要翻译：对于增强的访问控制，客户端在发送到块存储设备的每个读取或写入命令中包含令牌。块存储设备评估令牌以确定在指定的逻辑块地址是否允许读取或写入访问。例如，令牌包含在SCSI读或写命令的逻辑块地址字段中。客户端可以根据要访问的数据块的逻辑块地址来计算令牌，或者元数据服务器可以响应于元数据请求向客户端报告的每个区段的每个块地址中包括令牌。为了增强安全性，令牌还是客户端标识符，逻辑单元号以及客户端对文件系统数据块的特定范围的访问权限的函数。

摘要： Embodiments of the present invention provide a method of managing access of multiple client computers to a storage system that supports a limited number of logins. The method comprises, in response to a request to enable a subset of the clients to access resources of the storage system to perform a task, automatically configuring the storage system to provide the subset of the clients access to the resources, and, when the task is completed, automatically re-configuring the storage system so that the subset of the clients is no longer provided with access to the resources of the storage system.

摘要： An access control agent is advantageously deployed at a host device to prevent malicious use of a storage system by unauthorized hosts and users. In one embodiment the access control agent is disposed in a processing path between the application and the storage device. An application is mounted as an image file by a loop device to provide a virtual file system. The virtual file system is populated with access control information for each block of the file. Application I/O requests are mapped to physical blocks of the storage by the loop device, and the access control information is used to filter the access requests to preclude unauthorized requests from being forwarded to the storage client (and consequently the storage devices). With such an arrangement, access rights can be determined at I/O accesses, file and block granularity for each user.

摘要： For migration or de-duplication of a file system having a large number of files, a utility program traverses the file system to create a log of file-specific information about the file system. For identification of duplicates, the utility program produces a signature for each file. Respective instances of the utility program are started on multiple nodes upon which the file system is mounted. A fully qualified pathname is compiled during transfer of the log to a database. Multiple databases can be produced for the file system such that each database contains the file-specific information for a specified range of inode numbers. The database also maintains classification state for each file. For example, for a migration or replication process, the classification state identifies whether or not the file has been untouched, copied, linked, secondary-ized, source deleted, or modified.

摘要： Fault-tolerant storage is provided using a distributed data storage system that receives input data from clients and divides that data into data blocks for storage. The data blocks are processed using a coding scheme that generates redundant level one error correction blocks (L1EC Blocks). The L1EC blocks enable the reconstruction of one or more damaged or inaccessible data blocks, so long as sufficient undamaged elements are still accessible. The L1EC blocks and the data blocks are divided into distribution sets and these sets are stored at a plurality of data storage locations. At each data storage location additional level two error correction blocks (L2EC blocks) are generated that provide local data redundancy. The L2EC blocks enable reconstruction of damaged elements at a data storage location without requiring communication with the other data storage locations.
