Abstract: A triple parity (TP) technique reduces overhead of computing diagonal and anti-diagonal parity for a storage array adapted to enable efficient recovery from the concurrent failure of three storage devices in the array. The diagonal parity is computed along diagonal parity sets that collectively span all data disks and a row parity disk of the array. The parity for all of the diagonal parity sets except one is stored on the diagonal parity disk. Similarly, the anti-diagonal parity is computed along anti-diagonal parity sets that collectively span all data disks and a row parity disk of the array. The parity for all of the anti-diagonal parity sets except one is stored on the anti-diagonal parity disk. The TP technique provides a uniform stripe depth and an optimal amount of parity information.

Abstract translation: 三重奇偶校验（TP）技术减少了针对存储阵列计算对角线和反对角奇偶校验的开销，适用于实现从阵列中的三个存储设备的并发故障的有效恢复。 沿对角线奇偶校验集计算对角线奇偶校验集，该集合跨越阵列的所有数据磁盘和行奇偶校验磁盘。 所有对角奇偶校验集的奇偶校验除了一个存储在对角奇偶校验磁盘上。 类似地，反对角奇偶校验是沿着反对角奇偶校验集计算的，它们共同跨越阵列的所有数据盘和行奇偶校验盘。 所有反对角奇偶校验集的奇偶校验除了一个存储在反对角奇偶校验磁盘上。 TP技术提供均匀条纹深度和最优量的奇偶校验信息。

Abstract: Verifying data integrity and parity consistency of data blocks in an array of mass storage devices includes retrieving a row parity algebraic signature and a diagonal parity algebraic signature for one or more data blocks, a row parity block and a diagonal parity block. The row parity algebraic signatures of the one or more data blocks are logically combined to generate a first result and the first result is compared to the retrieved row parity algebraic signature for the row parity block. The diagonal parity algebraic signatures of the one or more data blocks and the row parity block are logically combined to generate a second result and the second result is compared to the retrieved diagonal parity algebraic signature for the diagonal parity block.

Abstract: 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 file system on the disk to a consistent state.

Abstract translation: 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。

Abstract: A symmetric triple parity (TP) technique in an array comprising a number p of storage devices, such as disks, with p being a prime number is provided. The p disks are organized as one row parity disk, two symmetric parity disks and p-3 data disks. Phantom diagonal and anti-diagonal parity disks assumed to be present are further assumed to contain a predetermined value, thereby enabling parity encoding/decoding utilizing the phantom (anti-) diagonal disks. Row parity and symmetric parity values are included within the computation of the diagonal and anti-diagonal parities; accordingly, the two symmetric parity and the row parity values may be computed using the same technique as used for a triple parity erasure, i.e., in a symmetric fashion.

Abstract translation: 提供了一种阵列中的对称三重奇偶校验（TP）技术，其包括p个存储设备，例如盘，其中p是素数。 p磁盘组织为一行奇偶校验磁盘，两个对称奇偶校验磁盘和p-3数据磁盘。 假定存在的幻影对角线和反对角奇偶校验盘进一步假设为包含预定值，从而使得能够利用幻像（反对角）盘进行奇偶校验编码/解码。 行奇偶校验和对称奇偶校验值包括在对角线和反对角奇偶校验的计算中; 因此，可以使用与用于三重奇偶校验擦除相同的技术来计算两个对称奇偶校验和行奇偶校验值，即以对称方式计算。

Abstract: Redundant Array of Inexpensive Disks (RAID) groups in a storage system are dynamically reconfigured by merging and splitting the RAID groups. When an indication of a change to data or system characteristics is received, disks in the RAID groups of the storage system can be reorganized to adapt to the change.

Abstract: Certain thiol and acylthiol compounds inhibit retrovirus growth by attacking the highly conserved zinc finger regions of essential viral proteins. These compounds, compositions containing them, and methods of using them to treat retroviral infections such as HIV are described. These compounds are also useful for preparation of vaccines comprised of inactivated retroviruses such as HIV, prevention of the transmission of such retroviruses, and detection of retroviral proteins.

Abstract: Embodiments of the invention provide for improved separation of switching material by creating a diversion of the activating force. In one embodiment at least one structural element is positioned in close proximity to an inlet for the actuating force to influence the actuating force to fully separate the switching material. Structural elements may include protrusions, either adjacent to the inlet or approximately across the channel from the inlet, as well as at least one additional inlet. The diversion can be created, if desired, by forces coming from opposite sides. Embodiments of the invention make use of non-wettable surfaces lining the channel in regions where switching material is to break into separate volumes, and wettable surfaces away from such regions. Embodiments of the invention provide for multi-pole, multi-throw switching.

Abstract: 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.
