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： 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： Aspects of the subject matter described herein relate to a distributed network name. In aspects, computers of a cluster have components of a distributed network name service. The network name service has a leader and clones that are hosted on the computers of the cluster. The leader is responsible for updating a name server with network names and addresses of the computers. The leader is also responsible for configuring a security server that allows clients to securely access the computers. The network name service provides credentials to local security authorities of the computers so that a client that attempts to access a service of the computers can be authenticated.
