    Abstract: Methods and systems provided herein involve extracting an input/output (I/O) operation from a packet received over an I/O pipeline, the I/O operation comprising either a read request to read data from at least one storage device or a write request to write data to the at least one storage device; determining that an address associated with the I/O operation exists in a lookup table that is provided for thin provisioning of the at least one storage device; performing one or more RAID calculations associated with the at least one storage device based on the address and the I/O operation; and accessing the at least one storage device to perform the I/O operation based on the one or more RAID calculations; and second processing component configured to carry out a second set of operations that occur when the address associated with the I/O operation does not exist in the lookup table.

    Abstract: A peripheral device includes a host interface and processing circuitry. The host interface is configured to communicate with a host over a peripheral bus. The processing circuitry is configured to expose on the peripheral bus a peripheral-bus device that communicates with the host using a bus storage protocol, to receive, using the exposed peripheral-bus device, Input/Output (I/O) transactions that are issued by the host, and to complete the I/O transactions for the host in accordance with a network storage protocol, by running at least part of a host-side protocol stack of the network storage protocol.

    Abstract: One embodiment includes data communication apparatus including a storage sub-system to be connected to storage devices, and processing circuitry to manage transfer of content with the storage devices over the storage sub-system responsively to content transfer requests, while pacing commencement of serving of respective ones of the content transfer requests responsively to availability of spare data capacity of the storage sub-system, find a malfunctioning storage device currently assigned a given data capacity of the storage sub-system and currently assigned to serve at least one content transfer request, and reallocate the given data capacity of the storage sub-system currently assigned to the malfunctioning storage device for use by at least another one of the storage devices while the at least one content transfer request assigned to be served by the malfunctioning storage device is still awaiting completion by the malfunctioning storage device.
