Abstract: Techniques are provided for combining data block and checksum block I/O into a single I/O operation. Many storage systems utilize checksums to verify the integrity of data blocks stored within storage devices managed by a storage stack. However, when a storage system reads a data block from a storage device, a corresponding checksum must also be read to verify integrity of the data in the data block. This results in increased latency because two read operations are being processed through the storage stack and are being executed upon the storage device. To reduce this latency and improve I/O operations per second, a single combined I/O operation corresponding to a contiguous range of blocks including the data block and the checksum block is processed through the storage stack instead of two separate I/O operations. Additionally, I/O operation may be combined into a single request that is executed upon the storage device.

Abstract: A photovoltaic (PV) module mounting system can have mounting clips that can be moved up and down a roof, and can allow the height of the mounting clips to be adjusted relative to the roof. At least a portion of the system can be made of a non-conductive material so that the system can be free of a grounding unit. The system can allow solar modules to be quickly installed, and can allow the solar modules to be removed quickly for repair or in the event of a fire.

Abstract: A device, which may be a peripheral device or a host computing device, comprises a communication interface, a memory and a processor. The processor is arranged to detect imminent disconnection of a communication link between the peripheral device and the host computing device and in response to detecting the imminent disconnection of the communication link, to trigger a data transfer from the host computing device to the peripheral device via the communication interface. The data transfer defines, at least in part, a fixed output data set which, after disconnection, is output via an output device in the peripheral device.
