Abstract: A reversible gerotor pump system is provided. The gerotor pump system includes a cylindrical housing with a 180° slot, an eccentric ring with a locking pin fixed thereto and movably engaged in the slot; an outer rotor and inner rotor with meshed teeth, and shaft for driving inner rotor and system. The eccentric ring has a convex profile on the outer diameter. A positive contact system, which can be a spring-and-plunger system or frictional disc brake system is provided to increase frictional force between the eccentric ring and the outer rotor. The locking pin moves in the slot with clearance at both rotation directions to provide a self-damping effect. The suction port has prolongations at both upstream and the downstream sides to increase filling time such that the pump can have a fill speed of above 5000 rpm, and the volumetric efficiency is at least 90% at 5000 rpm.

Abstract: Apparatus and method for servicing data transfer commands in a computer environment using a selected protocol such as NVMe (Non-Volatile Memory Express). In some embodiments, a secure connection is established between a client device and a bridge device across an interface. A controller of the bridge device presents a unitary namespace as an available memory space to the client device. The controller further communicates with a plurality of downstream target devices to allocate individual namespaces within main memory stores of each of the target devices to form a consolidated namespace to support the unitary namespace presented to the controller. In this way, the bridge device can operate as an NVMe controller with respect to the client device for the unitary namespace, and as a virtual client device to each of the target devices which operate as embedded NVMe controllers for the individual namespaces.

Abstract: Method and apparatus for offloading upstream processing tasks to peer groups of downstream data storage devices. A peer control circuit forms a peer group of storage devices in response to a detected processing bottleneck associated with a network controller. One of the storage devices in the peer group is designated as a primary device, and is responsible for interface communications, for subdividing the processing task for execution by secondary devices in the peer group, and coordinating overall execution. The peer group and the processing task are selected to avoid or minimize the processing bottleneck at the network controller level while maintaining ongoing data transfer performance at the storage device level. A list of available device resources and capabilities may be maintained by the peer control circuit. Offloaded tasks can include data rebuilds, cryptographic functions, new device authentication operations, and the like. Multiple overlapping peer groups can be formed as needed.

Abstract: A distributed data storage system may connect a host to a device and a dedication module. The dedication module can identify a manufacturing origin of the device before dedicating a type of host-generated data access request to the device. The type of host-generated data access request is chosen by the dedication module in response to an operating capability correlated to the device by the dedication module based on the identified manufacturing origin. At least one host-generated request of the dedicated type is then completed with the device.

Abstract: A distributed data storage system can be configured with a host connected to a first device and an initialization module that performs a default initialization procedure on the first device in response to detecting the first device has an unknown manufacturing origin. Conducting the default initialization procedure may allow the first device to service data access requests from the host. In response to the connection of a second device to the host and initialization module, a manufacturing origin of the second device is identified with the initialization module before the initialization module customizes the default initialization procedure to a custom procedure that is executed to allow the second device to satisfy a background operation prescribed by the initialization module.

Abstract: A distributed data storage system can be configured with a host connected to a device and a distribution module.

The manufacturer installed operating parameters of the device are then used to complete the system operation.

Abstract: During operation, an access point may receive, associated with other access points, information specifying one or more communication-performance metrics associated with the shared band of frequencies. Then, based at least in part on the one or more communication-performance metrics, the access point may determine a proposed channel and/or a proposed channel width for use by the access point during communication in a shared band of frequencies. Moreover, the access point may provide, addressed to the other access points, second information specifying the proposed channel and/or the proposed channel width. Next, the access point may receive, associated with the other access points, feedback about the proposed channel and/or the proposed channel width. Furthermore, based at least in part on the feedback, the access point may select a channel and/or a channel width for use by the access point during communication in the shared band of frequencies.

Abstract: In an approach for automatic vertical partitioning of fact tables in a distributed query engine a processor analyzes a sample end-user workload of queries to extract filter predicates associated with each of multiple fact tables relating to a big data store. A processor, for each fact table, and for each column in the fact table to which a filter predicate is applied and where coarsification is required, generates a candidate partitioning expression incorporating an adjustment to a coarsification function based on a data distribution of values in the column. A processor scores the candidate partitioning expressions for each fact table based on cost data relating to the sample end-user workload and selects one or more candidate partitioning expressions to optimize partitioning of each fact table with each partition data being placed in a separate directory in a distributed file system.
