摘要： A fluidic device is provided that includes a body and a contiguous electrically conductive layer. The body has interior and exterior surfaces. The interior surface defines at least a well and a fluid-transporting feature, e.g., a microfeature in fluid-communication with the well. The well has a sidewall and an exterior opening terminating at the exterior surface. The contiguous electrically conductive layer is located on at least the sidewall of the well and selected regions of the interior and exterior surfaces so as to form a contact pad region on the exterior surface in electrical communication with any fluid within the fluid-transporting feature. Also provided is a method for forming a fluidic device.

摘要： A storage server stores data in a stripe of a parity group that includes a plurality of data storage devices to store data and a parity storage device to store parity information. The stripe includes a data block from each of the data storage devices and a parity block from the parity storage device. The storage server receives a data access request specifying a data block in the stripe, and a lost write detection module detects an error in the data block. The lost write detection module compares a first storage device signature stored in a metadata field associated with the data block to a second storage device signature stored in a global field of the data storage device containing the data block. If the first storage device signature matches the second storage device signature, the lost write detection module compares a consistency point count stored in the metadata field to a reconstructed consistency point count. If the reconstructed consistency point count is greater than the consistency point count stored in the metadata field, the lost write detection module identifies the error as a lost write error for the data block. Accurately detecting and identifying the location of a lost write allows the storage server to correct the error and provide a user with a complete and accurate set of data.
摘要翻译：存储服务器将数据存储在包括多个数据存储设备的奇偶校验组的条带中以存储数据，并且奇偶校验存储设备存储奇偶校验信息。条带包括来自每个数据存储设备的数据块和来自奇偶校验存储设备的奇偶校验块。存储服务器接收指定条带中的数据块的数据访问请求，并且丢失写入检测模块检测数据块中的错误。丢失的写入检测模块将存储在与数据块相关联的元数据字段中的第一存储设备签名与存储在包含数据块的数据存储设备的全局字段中的第二存储设备签名进行比较。如果第一存储设备签名与第二存储设备签名匹配，则丢失写入检测模块将存储在元数据字段中的一致性点数与重建的一致性点数进行比较。如果重建的一致性点数大于存储在元数据字段中的一致性点数，则丢失的写入检测模块将错误识别为数据块的丢失写入错误。准确检测和识别丢失写入的位置允许存储服务器纠正错误，并为用户提供完整和准确的数据集。

摘要： A parity pattern defines a repeated distribution of parity blocks within a distributed parity disk array (“DPDA”). The parity pattern identifies on which disks the parity block or blocks for a stripe are located. When a new disk is added to the DPDA, the parity pattern is modified so that the distribution of parity blocks within the parity pattern is even. Parity blocks within the DPDA are then redistributed to conform with the modified parity pattern.

摘要： An n-way parity protection technique enables recovery of up to n storage device (e.g., disk) failures in a parity group of a storage array encoded to protect against n-way disk failures. The storage array is created by first configuring the array with m data disks, where m=p−1 and p is a prime number and a row parity disk. n−1 diagonal parity disks are then added to the array. Each diagonal parity set (i.e., diagonal) is associated with a slope that defines the data and row parity blocks of the array that are included in the diagonal. All diagonals having a common slope within a parity group are organized as a diagonal parity class. For each diagonal parity class, a diagonal parity storage disk is provided to store the diagonal parity.

摘要： Storage servers use a fast, non-volatile or persistent memory to store data until it can be written to slower mass storage devices such as disk drives. If the server crashes before a write can complete, the data remains safely stored in non-volatile memory. If the data cannot be committed to disk when the server reboots (e.g. because the destination mass storage device is unavailable), it is stored in a file. When the disk reappears, the data in the file may be used to restore a file or filesystem on the disk to a consistent state.
摘要翻译：存储服务器使用快速，非易失性或永久性存储器来存储数据，直到它可以写入较慢的大容量存储设备（如磁盘驱动器）。如果服务器在写入完成之前崩溃，数据将保持安全地存储在非易失性存储器中。如果服务器重新启动（例如由于目标大容量存储设备不可用）而无法将数据提交到磁盘，则将其存储在文件中。当磁盘重新出现时，文件中的数据可能用于将磁盘上的文件或文件系统还原到一致状态。

摘要： A network storage server implements a method to maintain a parity declustered RAID organization with distributed hot sparing. The parity declustered RAID organization, which provides data redundancy for a network storage system, is configured as a RAID organization with a plurality of logical drives. The RAID organization is then distributed in a parity declustered fashion to a plurality of physical drives in the network storage system. The RAID organization also has a spare space pre-allocating on each of the plurality of physical drives. Upon failure of one of the plurality of physical drives, data stored in the failed physical drives can be reconstructed and stored to spare space of the surviving physical drives. After reconstruction, the plurality of logical drives remains parity-declustered on the plurality of surviving physical drives.

摘要： The input/output (I/O) performance of a hard disk drive in a mass storage computer system is evaluated to maintain efficiency by addressing I/O commands to sectors of the disk drive, evaluating the execution of the I/O commands to the sectors to obtain performance information for the sectors to which the I/O commands are addressed, comparing the performance information to a predetermined I/O performance criterion, and identifying any impaired sectors in which the performance information indicates less than the predetermined I/O performance criterion. Thereafter, further I/O commands to the impaired sectors are avoided.
