Abstract: In one embodiment, an encoder reads a set of data from memory cells to obtain retrieved data influenced by one or more distortion mechanisms as a result of having been stored. A quality metric is generated responsive to the retrieved data that changes in value responsive to differences between the user data and the associated retrieved data. A quality monitor establishes a relationship between a current value of the quality metric and a threshold value and monitors the relationship as being indicative of a degradation of the quality of the retrieved data, and selectively initiates an error response. In another embodiment, a correction value is iterated through a set of values as a quality metric is monitored such that the value of the quality metric which most closely approaches the value of the quality metric immediately subsequent to an initial writing of the data can be selected.

Abstract: Techniques for optimizing data storage are disclosed herein. In particular, methods and systems for implementing redundancy encoding schemes with data storage systems are described. The redundancy encoding schemes may be scheduled according to system and data characteristics. The schemes may span multiple tiers or layers of a storage system. The schemes may be generated, for example, in accordance with a transaction rate requirement, a data durability requirement or in the context of the age of the stored data. The schemes may be designed to rectify entropy-related effects upon data storage. The schemes may include one or more erasure codes or erasure coding schemes. Additionally, methods and systems for improving and/or accounting for failure correlation of various components of the storage system, including that of storage devices such as hard disk drives, are described.

Abstract: A method and system for increasing server cluster availability by requiring at a minimum only one node and a quorum replica set of replica members to form and operate a cluster. Replica members maintain cluster operational data. A cluster operates when one node possesses a majority of replica members, which ensures that any new or surviving cluster includes consistent cluster operational data via at least one replica member from the immediately prior cluster. Arbitration provides exclusive ownership by one node of the replica members, including at cluster formation, and when the owning node fails. Arbitration uses a fast mutual exclusion algorithm and a reservation mechanism to challenge for and defend the exclusive reservation of each member. A quorum replica set algorithm brings members online and offline with data consistency, including updating unreconciled replica members, and ensures consistent read and update operations.

Abstract: A control channel may be used to transmit control information, such as Downlink Control Information (DCI), to a mobile device from a network component, such as a base station or a base node. The mobile device may use a blind decoding scheme to detect DCIs. A DCI may be falsely detected by the mobile device. According to some embodiments, data that has been decoded by a blind decoder, from buffer data for a candidate control channel, is re-encoded. The re-encoded data is compared to buffer data for the control channel. The decoded data is treated as control information dependent on the comparison of the re-encoded data with the buffer data. In some embodiments, comparing the re-encoded data to the buffer data includes generating a metric as a function of a degree of similarity between the re-encoded data and the buffer data. The metric may be compared to a threshold.

Abstract: Systems and methods are provided for storing data in a portion of a non-volatile memory (“NVM”) such that the status of the NVM portion can be determined with high probability on a subsequent read. An NVM interface, which may receive write commands to store user data in the NVM, can store a fixed predetermined sequence (“FPS”) with the user data. The FPS may ensure that a successful read operation on a NVM portion is not misinterpreted as a failed read operation or as an erased NVM portion. For example, if the NVM returns an all-zero vector when a read request fails, the FPS can include at least one “1” or one “0”, as appropriate, to differentiate between successful and unsuccessful read operations. In some embodiments, the FPS may also be used to differentiate between disturbed data, which passes an error correction check, and correct data.

Abstract translation: 提供了用于将数据存储在非易失性存储器（“NVM”）的一部分中的系统和方法，使得可以在后续读取时以高概率确定NVM部分的状态。 可以接收写入命令以将用户数据存储在NVM中的NVM接口可以与用户数据一起存储固定的预定顺序（“FPS”）。 FPS可以确保在NVM部分上的成功读取操作不被误解为读取操作失败或被擦除的NVM部分。 例如，如果NVM在读请求失败时返回全零向量，则FPS可以适当地包括至少一个“1”或一个“0”，以区分成功和不成功的读取操作。 在一些实施例中，FPS还可用于区分经过错误校正检查的干扰数据和校正数据。
