    Abstract: A method for controlling a redundant storage system is proposed. A write request to a redundant storage system is received (310). A dataset that is to be written into the redundant storage system by the write request is determined (320). A portion of the dataset is logged into the redundant storage system for data recovery in case that a fault occurs in the redundant storage system (330). Thus, only a portion of the dataset is logged and the amount of the logged data may be reduced compared with the conventional redundant storage system. Further, the redundant storage system may be recovered in response to a fault occurring in the redundant storage system.

    Abstract: In accordance with implementations of the subject matter described herein, there provides a solution for multi-path RDMA transmission. In the solution, at least one packet is generated based on an RDMA message to be transmitted from a first device to a second device. The first device has an RDMA connection with the second device via a plurality of paths. A first packet in the at least one packet includes a plurality of fields, which include information for transmitting the first packet over a first path of the plurality of paths. The at least one packet is transmitted to the second device over the plurality of paths via an RDMA protocol. The first packet is transmitted over the first path. The multi-path RDMA transmission solution according to the subject matter described herein can efficiently utilize rich network paths while maintaining a low memory footprint in a network interface card.

    Abstract: According to implementations of the subject matter described herein, there is proposed a solution for supporting communications for an FPGA device. In an implementation, the FPGA device includes an application module and protocol stack modules. The protocol stack modules are operable to access target devices based on different communication protocols via a physical interface. The FPGA device further includes a universal access module operable to receive, from the application module, first data and a first identity of a first target device, the first target device acting as a destination of the first data, and transmit, based on the first identity and predetermined first routing information, the first data to a first protocol stack module accessible to the first target device via the physical interface. By introducing the universal access module, it is possible to provide unified and direct communications for the application module.

    Abstract: The techniques described herein reduce a rate at which a mobile device consumes energy when receiving, processing and storing data events (e.g., emails, instant messages, social networking messages and notifications, etc.). In various embodiments, the techniques may be implemented in accordance with a connected standby mode of operation for the mobile device. Therefore, the techniques may decouple data reception from data processing when exchanging data events in the connected standby mode. In various embodiments, the techniques may store persistent memory operations for multiple data events in a temporary cache and process the stored persistent memory operations as a batch (e.g., perform the persistent memory operations together). In various embodiments, the techniques may partition data storage space allocated for data communications applications on the mobile device.
