    Abstract: A computer implemented method of data decompression and verification includes decompressing a compressed data segment to generate a decompressed data region. The method also includes generating a segment vector array (SVA) including a number of segment vectors corresponding to data segments within the decompressed data region, each segment vector indicating a location and a size of a corresponding data segment. The method also includes transmitting the SVA to a chain plugin module and transmitting segment vector array data to a SVA-based message constructor. The method also includes constructing a SVA-based message including the location and size of data segments within the decompressed data region, and transmitting the SVA-based message to a hardware accelerator. The method also includes performing verification sessions at the hardware accelerator, each verification session corresponding to a specific data segment indicated by the SVA-based message.

    Abstract: One embodiment provides a computer implemented method of balancing mixed workload performance including monitoring the compression and decompression workload at a hardware accelerator using the hardware accelerator quality of service (QoS) scheduler; monitoring the compression and decompression workload at a CPU using the CPU QoS scheduler; comparing the workload at the hardware accelerator and the workload at the CPU; and allocating tasks between the hardware accelerator and the CPU to obtain an optimal bandwidth at the hardware accelerator and the CPU.

    Abstract: Embodiments of the present disclosure relate to method, device and computer program product for data backup. The method comprises: in response to receiving from a backup server a data stream to be backed up, dividing the data stream into a plurality of data segments; distributing the plurality of data segments to at least one computing node; in response to receiving an index of a corresponding data segment from a first computing node of the at least one computing node, looking up the index in a global index cache, the index being generated by the first computing node to uniquely identify the data segment, the global index cache storing indexes of data in a backup storage device; in response to the missing index in the global index cache, adding the index into the global index cache; and sending to the first computing node an indication to store the data segment in the backup storage device.

    Abstract: Embodiments of the present disclosure disclose methods and devices of data de-duplication. The method of data de-duplication performed at a client comprises: in response to receiving data to be backed up at a client, sampling the data to be backed up to obtain the sampled data; generating a signature for the sampled data; transmitting the signature to a master storage node in a storage cluster including a plurality of storage nodes, to allow the master storage node to select one storage node from the plurality of storage nodes; receiving an indication of the selected storage node from the master storage node; and transmitting, based on the indication, the data to be backed up to the selected storage node. Embodiments of the present disclosure also provide methods of data de-duplication performed at the master storage node and the slave storage node, and corresponding devices.

    Abstract: Embodiments are described for prioritizing input/output (I/O) operations dispatched from a storage media to a host bus adapter in a network, by tagging, in an I/O tagging module, the I/O operations in a file system supporting applications generating the I/O operations, wherein all child I/O operations initiated from a parent I/O operation are tagged with a same unique tag ID; tracking a time of arrival of each I/O operation of the I/O operations; and dispatching, in a transactional I/O scheduler, all sibling I/O's of the parent I/O operation based on a unique tag ID for the sibling I/Os, a respective time of arrival of each of the sibling I/Os, and defined quality of service (QoS) requirements.
