摘要： The techniques introduced herein provide for systems and methods for creating and managing a contention-free multi-path access to a distributed data set in a distributed processing system. In one embodiment, a distributed processing system comprises a plurality of compute nodes. The compute nodes are assembled into compute groups and configured such that each compute group has an attached or local storage system. Various data segments of the distributed data set are stored in data storage objects on the local storage system. The data storage objects are cross-mapped into each of the compute nodes in the compute group so that any compute node in the group can access any of the data segments stored in the local storage system via the respective data storage object.

摘要： A mechanism enables distributed atomic creation of client-private files using a distributed file system protocol. The mechanism provides an unlinked open operation that enables the distributed atomic creation of a client-private file that is not accessible by other clients. That is, the unlinked open operation creates a file, but does not generate a path name to the file within a file system. The unlinked open operation thus permits clients utilizing the file system protocol to create temporary or “scratch files” that are not accessible by other clients.
摘要翻译：一种机制可以使用分布式文件系统协议实现客户端 - 专用文件的分布式原型创建。该机制提供了一个未链接的打开操作，使得无法由其他客户端访问的客户机专用文件的分布式原子创建。也就是说，未连接的打开操作创建一个文件，但不会在文件系统中生成文件的路径名。因此，未连接的打开操作允许利用文件系统协议的客户端创建不能被其他客户端访问的临时或“临时文件”。

摘要： A method and apparatus for operating a plurality of computers is disclosed. A file is maintained on a selected computer of the plurality of computers. An open request for the file is sent by a first computer of the plurality of computers to the selected computer, the open request including a first token. The file is opened for the first computer in response to the open request. An open request is sent for the file by a second computer to the selected computer, the open request including a second token. The first token is compared with the second token. If the first token and the second token match, opening the file for the second computer, and if the first token and the second token do not match, not opening the file for the second computer.

摘要： A system and method for configuring a storage network utilizing one or more storage appliances to utilize the multi-block based protocol nature of the storage appliances. By configuring the storage network, data served by the storage appliance may be accessed by a plurality of protocols simultaneously. Illustratively, a virtual disk (vdisk) may be access by clients using the FCP protocol over a FC network while other clients access the vdisk using the iSCSI protocol over a TCP/IP network.

摘要： A system and method proxies data access commands acrossed a cluster interconnect between storage appliances and a cluster using a file-level protocol. Each storage appliance activates two ports per data access, a local port for data access requests directed to clients of the storage appliance and a proxy port for data access requests directed to the partner storage appliance. Clients utilizing multi-pathing software may send data access requests to either the local port of the storage appliance or the proxy port of the storage appliance. The system and method improves high availability, especially during a loss of connectivity due to non-storage appliance hardware failure.

摘要： A system and method enabling transparent access to blocks, such as virtual disks, stored on a storage system using a file-based protocol. The system and method traps in-coming file-based protocol open commands to check for a predetermined modification to the file name. If the system and method detects the predetermined modification, then the virtual disk associated with the file name is exported to the client issuing the open command and the client receives a response from the storage system. The client, in response to receiving the response to the open command, creates a new device instantiation for reading and writing raw data to the virtual disk.
