摘要： A mechanism is provided for managing backups. A plurality of logical partitions are generated in a computer system, each logical partition having assigned a respective first portion of the main memory in the computer system as a resource and each logical partition hosting at least one application program which consumes at least a fraction of the first main memory portion of the logical partition. A second portion of the main memory is used as a global memory, the global memory not overlapping with any one of the first main memory portions. For each of the one or more of the logical partitions, one or more images of the first memory portion consumed by the at least one application program hosted by the logical partition are stored as a backup in the global memory.

摘要： An “erasure code” is an encoding of multiple different sets of data. Redundant copies of data are maintained in such erasure codes, thereby utilizing only a fraction of the storage capacity of unencoded copies. Erasure codes are efficiently generated, with a minimum of processing resources utilizing XOR functionality. Additionally, erasure codes are generated from local data, thereby avoiding the consumption of network resources. At least one unencoded copy of a set of data is maintained, while the remaining, redundant copies are encoded into erasure codes. Requests for data are provided from the unencoded copy. Should it fail, a new unencoded copy can be generated by another computing device having access to both an erasure code as well as unencoded copies of the other data that was also pressed into that erasure code. Multiple failures can be survived through recursive application of such a decoding of encoded data.
摘要翻译： “擦除代码”是多个不同数据集的编码。冗余的数据副本被保留在这样的擦除代码中，从而仅利用未编码副本的存储容量的一小部分。有效地生成擦除代码，利用XOR功能的最少的处理资源。此外，从本地数据生成擦除码，从而避免了网络资源的消耗。保持一组数据的至少一个未编码的副本，而剩余的冗余副本被编码为擦除代码。未经编码的副本提供数据请求。如果它失败，则可以由具有访问擦除代码的另一个计算设备以及也被压入该擦除代码的其他数据的未编码副本来生成新的未编码副本。可以通过对编码数据的这种解码的递归应用来存活多个故障。

摘要： Methods and apparatus relating to processing out of order transactions for mirrored subsystems. A first device (that is mirroring data from a second device) includes a cache to track out of order write operations prior to writing data from the write operations to memory. A register may be used to track the state of the cache in response to receipt of a special transaction, which may be a posted transaction or snapshot. The first devise transmits an acknowledgement of commitment of the data to memory once all cache entries, as recorded at a select point by the register, are emptied or otherwise invalidated. Devices may communicate via a peripheral component interconnect express (PCIe) interconnect, and may include a point-to-point or serial link. Various components may be on the same integrated circuit die. An uninterrupted power supply or batteries may supply power in response to a power failure.

摘要： A method begins with a processing module of a dispersed storage network (DSN) executing a write operation to write a plurality of sets of encoded data slices to DSN memory, where the write operation includes temporarily storing encoded data slices in cache memory. The processing module receives a read request for a portion of the data object and determines whether a decode threshold number of encoded data slices of a set is stored in the cache memory. When less than the decode threshold number of encoded data slices is stored in the cache memory, the processing module retrieves encoded data slices from the DSN memory to obtain the decode threshold number of encoded data slices, decodes the decode threshold number of encoded data slices to recover a corresponding data segment, and outputs the recovered corresponding data segment.

摘要： Persistent data storage is provided by a computer program product that includes computer program code configured for receiving a low latency store command that includes write data. The write data is written to a first memory device that is implemented by a nonvolatile solid-state memory technology characterized by a first access speed. It is acknowledged that the write data has been successfully written to the first memory device. The write data is written to a second memory device that is implemented by a volatile memory technology. At least a portion of the data in the first memory device is written to a third memory device when a predetermined amount of data has been accumulated in the first memory device. The third memory device is implemented by a nonvolatile solid-state memory technology characterized by a second access speed that is slower than the first access speed.

摘要： Mass storage uses additional error correction codes. The additional codes can be stored in a storage medium (e.g., volatile solid state memory) separate from the associated data. The additional codes may be written to a nonvolatile medium. The additional codes may be transient. The additional codes may be cached. As long as present, the additional codes may be used to correct user data in synch with or in addition to other error detection and correction codes.

摘要： In one embodiment, a method of coordinating data recovery in a storage stack with a hierarchy of layers includes, upon an input/output (I/O) request from a layer of the stack, issuing a help response to recover the data from a higher layer in hierarchy order. The method further includes processing the help response, at the higher layer, by issuing a return code of success or further help response to an even higher layer.
