Abstract: Methods and systems for a computing cluster are provided. An application programming interface (API) at a manager application is exposed. The API specifies input identifying nodes and connections between the nodes to implement storage protection policies in the computing cluster. A user input that includes instructions to implement multiple destination nodes and respective connections between a source node and the destination nodes is received. A topology that includes the source node, the destination nodes, and the connections between the source node and the destination nodes is traversed. Based on traversing the topology, commands are sent to a storage system of the cluster to implement a destination volume corresponding to the destination node and multiple protection configurations. Each of the protection configurations corresponds to a respective one of the connections.

Abstract: A method includes exposing an application programming interface (API) at a manager application, the manager application running on a server in a computing cluster, wherein the API specifies input identifying nodes and connections between the nodes to implement storage protection policies in the computing cluster; receiving user input to the manager application according to the API, where the user input includes instructions to implement a secondary node and a connection between a primary node and the secondary node, the user input received at the manager application at a level of specificity that includes the secondary node and the connection between the primary node and the secondary node, thereby defining arbitrary protection topologies.

Abstract: A test fixture for making an electrical connection with electrical contacts of a circuit board includes jaws made of conductive material. The jaws may be monolithic pieces of copper, with a pair of sections that pivot along a thin hinged portion at one end. The jaws float freely within a test fixture housing, allowing the jaws to reposition themselves within the housing to adjust to variations in position of the electrical contacts. A clamping mechanism pushes free ends of the jaw sections toward one another, causing engagement between the sections and the electrical contacts. The test fixture provides a way to provide good contact area and good contact pressure, allowing large-current flows between the jaws and the electrical contacts, while at the same time providing substantially no force on the circuit board in a direction perpendicular to the circuit board.

Abstract: An apparatus (10) for testing an operational status of a missile interface system includes a portable control unit (16) having an interface panel (28). The interface panel (28) has a plurality of umbilical ports adapted to receive data from a plurality of missile stations (12) via a corresponding plurality of umbilical cables (18). The interface panel (28) is further includes a coaxial port (40), adapted to receive data from a radar trap (22) via a coaxial cable (20). The apparatus further includes a fixture assembly (116) having a main body portion (120). The main body portion (120) has a channel (122) through which a first end of the umbilical cable (18) is allowed to pass. The fixture assembly (116) is adapted to be releasably mounted to a missile station (12).
