摘要： An apparatus, system, and method are disclosed for caching data. A storage request module detects an input/output (“I/O”) request for a storage device cached by solid-state storage media of a cache. A direct mapping module references a single mapping structure to determine that the cache comprises data of the I/O request. The single mapping structure maps each logical block address of the storage device directly to a logical block address of the cache. The single mapping structure maintains a fully associative relationship between logical block addresses of the storage device and physical storage addresses on the solid-state storage media. A cache fulfillment module satisfies the I/O request using the cache in response to the direct mapping module determining that the cache comprises at least one data block of the I/O request.

摘要： An apparatus, system, and method are disclosed for managing data storage. The method includes determining that an error correcting code (ECC) block comprises uncorrectable errors. The ECC block is stored across a plurality of memory devices. The method includes iteratively substituting replacement data, within data of the ECC block, for individual memory devices of the plurality of memory devices to form substitute ECC blocks until one of the substitute ECC blocks is correctable using the error correcting code for the ECC block. The method includes providing corrected data from the correctable one of the substitute ECC blocks.

摘要： A virtual storage layer (VSL) presents logical address space of a non-volatile storage device. The VSL maintains logical interfaces to the non-volatile storage device, which may include arbitrary, any-to-any mappings between logical identifiers and storage resources. Data may be stored on the non-volatile storage device in a contextual format, which includes persistent metadata that defines the logical interface of the data. The VSL may modify the logical interface of data that is stored in the contextual format. The modified logical interface may be inconsistent with the existing contextual format of the data on the non-volatile storage media. The VSL may provide access to the data in the inconsistent contextual format through the modified logical interface. The contextual format of the data may be updated to be consistent with the modified logical interface in a write out-of-place storage operation.

摘要： An apparatus, system, and method are disclosed for managing data in a solid-state storage device. A solid-state storage and solid-state controller are included. The solid-state storage controller includes a write data pipeline and a read data pipeline The write data pipeline includes a packetizer and an ECC generator. The packetizer receives a data segment and creates one or more data packets sized for the solid-state storage. The ECC generator generates one or more error-correcting codes (“ECC”) for the data packets received from the packetizer. The read data pipeline includes an ECC correction module, a depacketizer, and an alignment module. The ECC correction module reads a data packet from solid-state storage, determines if a data error exists using corresponding ECC and corrects errors. The depacketizer checks and removes one or more packet headers. The alignment module removes unwanted data, and re-formats the data as data segments of an object.

摘要： An apparatus, system, and method are disclosed for determining a read voltage threshold for solid-state storage media. A data set read module reads a data set from storage cells of solid-state storage media. The data set is originally stored in the storage cells with a known bias. A deviation module determines that a read bias for the data set deviates from the known bias. A direction module determines a direction of deviation for the data set. The direction of deviation is based on a difference between the read bias of the data set and the known bias. An adjustment module adjusts a read voltage threshold for the storage cells of the solid-state storage media based on the direction of deviation.

摘要： An apparatus, system, and method are disclosed for validating that correct data is read from a storage device. A read request receiver module receives a read storage request to read a data segment of a file or object stored on a data storage device. The storage request includes one or more source parameters for the data segment. The source parameters include one or more virtual addresses that identify the data segment. A hash generation module generates one or more hash values from the virtual addresses. A read data module reads the requested data segment and returns one or more data packets and corresponding stored hash values stored with the data packets. The stored hash values were generated from a data segment written to the data storage device that contains data of the data packets. A hash check module verifies that the generated hash values match the respective stored hash values.

摘要： An apparatus, system, and method are disclosed for managing eviction of data. A grooming cost module determines a grooming cost for a selected region of a nonvolatile solid-state cache. The grooming cost includes a cost of evicting the selected region of the nonvolatile solid-state cache relative to other regions. A grooming candidate set module adds the selected region to a grooming candidate set in response to the grooming cost satisfying a grooming cost threshold. A low cost module selects a low cost region within the grooming candidate set. A groomer module recovers storage capacity of the low cost region.

摘要： An auto-commit memory is capable of implementing a pre-configured, triggered commit action in response to a failure condition, such as a loss of power, invalid shutdown, fault, or the like. A computing device may access the auto-commit memory using memory access semantics (using a memory mapping mechanism or the like), bypassing system calls typically required in virtual memory operations. Since the auto-commit memory is pre-configured to commit data stored thereon in the event of a failure, users of the auto-commit memory may view these memory semantic operations as being instantly committed. Since operations to commit the data are taken out of the write-commit path, the performance of applications that are write-commit bound may be significantly improved.
摘要翻译：自动提交存储器能够响应于诸如功率损失，无效关机，故障等的故障状况来实现预配置的触发提交动作。计算设备可以使用存储器访问语义（使用存储器映射机制等）来访问自动提交存储器，绕过虚拟存储器操作中通常需要的系统调用。由于自动提交存储器在发生故障的情况下被预配置为提交存储在其上的数据，所以自动提交存储器的用户可以将这些存储器语义操作视为立即提交。由于提交数据的操作是从写入提交路径中取出的，因此可以显着提高写入提交绑定的应用程序的性能。
