  • Patent number: 11422744
    Abstract: In data storage systems, pooled storage resources may be organized into logical disk groups. Adding an additional disk group to such data storage systems requires identifying a suitable disk group from numerous candidates that may be available to the data storage system via a network. Embodiments identify IHSs (Information Handling Systems), such as rack-mounted servers installed within a data center, that include available disk groups. The servers with available disk groups are classified based on various trust parameters, such as their security settings and their hardware and software configurations. Based on the number of trust parameters with which the servers are classified, the servers are ranked, thus indicating their suitability for providing trusted disk groups to the storage system. Available disk groups from the top ranked server may be designated for use by the storage system.

    Abstract: The present disclosure describes a data transmission method, a timing controller, a source driver, and a data transmission system. The method includes: when the timing controller transmits data to the source driver at a speed n times a preset speed, the timing controller suspends transmission of valid data with the source driver after completing transmission of a first data packet; and the transmission of valid data with the source driver is resumed at a transmitting time of a second data packet; the first data packet and the second data packet each includes valid data of a row of sub-pixels, or each includes valid data of a frame. The present disclosure completes the transmission of the first data packet in advance by increasing the transmission speed, then suspends the data transmission, and resumes the data transmission at the transmitting time of the second data packet, thereby reducing the power consumption.

    Abstract: Adaptive data storing for a data storage system employing erasure coding is disclosed. Incoming data for storage can be encoded according to an erasure code scheme that can generate k coding fragments and in data fragments for each unit of incoming data. The portions of the encoded fragments resulting from the incoming data can be stored among different storage devices of data storage system. A first portion of the encoded fragments can be stored according to a first ratio. A storage system performance indicator based on the storing of the first portion can trigger an update of the first ratio, resulting in a second ratio that can be applied to storage of a second portion of the encoded fragments. The use of the disclosed variable k-to-m ratio can reduce instances of heavily burdened storage devices that can negatively impact performance of the data storage system.

  • Patent number: 11115221
    Abstract: Methods for verifying rebuilt data in a dispersed storage network (DSN). In various examples, a storage unit of the DSN receives a rebuilt encoded data slice of a set of encoded data slices and a set of corresponding integrity values. An integrity function is performed on the set of integrity values to calculate an integrity value of the set of integrity values, which is then compared to a locally stored value. If the values match, the set of integrity values is validated. Another integrity function is performed on the rebuilt encoded data slice to produce a calculated integrity value of the received encoded data slice. The encoded data slice is validated and stored when the calculated integrity value compares favorably to the corresponding value of the validated set of integrity values. Proof of authenticity information from other storage units may be employed to further validate the set of integrity values.

  • Patent number: 11074919
    Abstract: In encoding, a frequency-domain sample sequence derived from an acoustic signal is divided by a weighted envelope and is then divided by a gain, the result obtained is quantized, and each sample is variable-length encoded. The error between the sample before quantization and the sample after quantization is quantized with information saved in this variable-length encoding. This quantization is performed under a rule that specifies, according to the number of saved bits, samples whose errors are to be quantized. In decoding, variable-length codes in an input sequence of codes are decoded to obtain a frequency-domain sample sequence; an error signal is further decoded under a rule that depends on the number of bits of the variable-length codes; and from the obtained sample sequence, the original sample sequence is obtained according to supplementary information.
