摘要： The representation of storage devices on computers (e.g., as logical volumes) may be complicated by the pooling of multiple storage devices in order to apply redundancy plans such as mirroring and checksumming. Presented herein is a storage device driver configured to operate as a storage device interface generating representations of the storage regions of the storage devices; to claim those regions as a storage controller; and to expose pooled storage regions as logical disks. Additionally, the storage device driver may support the inclusion of storage devices in a cluster, comprising nodes that may be appointed as managers of the storage pool configuration; as managers of the storage devices; as owners having exclusive read/write access to the storage pool or cluster resources; and as cluster resource writers having excusive write access to a cluster resource. The nodes of the cluster may interoperate to share the storage devices while avoiding write conflicts.

摘要： A cluster based file service may operate on a cluster of two or more independent devices that have access to a common data storage. The file service may have a namespace definition with each device in the cluster, but may be modified by any device operating the file service. Each instance of the file service may identify and capture a command that changes the namespace structure and cause the change to be propagated to the other members of cluster. If one of the devices in the cluster does not successfully perform an update to the namespace structure, that device may be brought offline. The cluster based file service may permit adding or removing devices from the cluster while the file service is operating, and may provide a high throughput and high availability file service.

摘要： The present invention extends to methods, systems, and computer program products for implementing persistent reservation techniques for establishing ownership of one or more physical disks. These persistent reservation techniques can be employed to determine ownership of physical disks in a storage pool as well as in any other storage configuration. Using the persistent reservation techniques of the present invention, when a network partition occurs, a defender of a physical disk does not remove a challenger's registration key until the defender receives notification that the challenger is no longer in the defender's partition. In this way, pending I/O from applications executing on the challenger will not fail due to the challenger's key being removed until the proper ownership of the physical disk can be resolved.

摘要： Coordinating methods of I/O access to a shared data store. A method includes at a node, in a distributed system, performing one or more I/O operations on the shared data store using direct I/O access on a virtual data container. Direct I/O access includes performing I/O operations directly from the node to the shared data store including not having an owner node perform the I/O operation on the shared data store on the node's behalf. The owner node is a different node than the node doing the direct I/O operation. The owner node accesses the shared data store through a local data container. The method further includes determining that one or more subsequent I/O operations should be performed using redirected I/O access, where I/O operations are directed through a centralized node. The method further includes indicating to nodes in the distributed system to switch to redirected I/O access method.
摘要翻译：对共享数据存储的I / O访问的协调方法。一种方法包括在分布式系统的节点处，在虚拟数据容器上使用直接I / O访问在共享数据存储器上执行一个或多个I / O操作。直接I / O访问包括直接从节点到共享数据存储器的I / O操作，包括没有所有者节点代表节点在共享数据存储上执行I / O操作。所有者节点与执行直接I / O操作的节点不同。所有者节点通过本地数据容器访问共享数据存储。该方法还包括确定使用重定向I / O访问来执行一个或多个后续I / O操作，其中I / O操作通过集中式节点引导。该方法还包括向分布式系统中的节点指示切换到重定向的I / O访问方法。

摘要： Defining a storage topology of a distributed computing system including a set of machine nodes. A method includes dynamically receiving from a number of nodes in the distributed computing system information about storage devices. Each node sends information about storage devices connected to that particular node. The information is sent dynamically from each node as conditions related to storage change and as a result of conditions related to storage changing. From the received information, the method includes dynamically constructing a storage topology representation of the distributed computed system.

摘要： The present invention extends to methods, systems, and computer program products for automatically transferring configuration of a virtual machine from one cluster to another cluster. The invention enables an administrator to transfer configuration of a virtual machine by simply specifying a virtual machine to be transferred. The invention then inspects the configuration of the virtual machine on the old cluster as well as the configuration of the old cluster, including the storage (e.g. virtual hard disk) used by the cluster, and then configures a new virtual machine on a new cluster accordingly to match the configuration of the old virtual machine. Similar techniques can also be applied to transfer configuration of an SMB file server.
