摘要： Techniques for using heterogeneous disks of dissimilar access speeds in a redundant disk array can be used to support growing the file-system while it is on-line. In general, such techniques are for use in a system that contains identical data across heterogeneous disks. In a RAID1 system having two disks, there is a data disk and a copy disk. The copy disk contains a copy of the data stored on the data disk. When more than two disks are used in a RAID1 system, the additional disks are used as copy disks instead of additional storage. The disclosed techniques improve the throughput of a heterogeneous array that contains disks with different speeds, such as an SSD and HDD combination. The read speeds can be increased by splitting up each of the data requests and utilizing parallel reads across more than one of the disks in the array.
摘要翻译：在冗余磁盘阵列中使用不同访问速度的异类磁盘的技术可用于在联机时支持增长文件系统。一般来说，这些技术适用于跨异构磁盘包含相同数据的系统。在具有两个磁盘的RAID1系统中，有一个数据磁盘和一个复制磁盘。复制磁盘包含存储在数据磁盘上的数据的副本。当在RAID1系统中使用两个以上的磁盘时，其他磁盘将用作复制磁盘而不是附加存储。所公开的技术提高了包含具有不同速度的盘的异构阵列（诸如SSD和HDD组合）的吞吐量。读取速度可以通过分割每个数据请求和利用阵列中多个磁盘的并行读取来提高。

摘要： An improved interface for managing disparate read, write, and erase sizes and operations in data storage devices is provided. By improving an interface between a storage system driver layer and associated storage devices, performance of data storage is improved, including improving data storage speed and storage media endurance. Storage media management operations are made more efficient and consistent by providing improved types and sequences of commands sent from the driver layer to the device control layer such that data write operations are performed in a sequential manner as write commands are directed to portions of data as opposed to buffering individual portions of data followed by a large wholescale write/erase process for the buffered data.

摘要： System, methods and apparatus are described that facilitate access to a memory device. A memory space within the memory device is divided into a plurality of storage bank domains. Thereafter, application interface circuits configured to access the memory space are classified into a plurality of interface groups based on one or more application usage requirements. Each interface group of the plurality of interface groups is assigned to a corresponding storage bank domain from the plurality of storage bank domains. Access between each interface group and the corresponding storage bank domain is then provided, wherein a first application interface circuit of a first interface group accesses a first corresponding storage bank domain while a second application interface circuit of a second interface group accesses a second corresponding storage bank domain.

摘要： A method for managing metadata in a scale out storage system is disclosed. The system includes a plurality of nodes, a storage pool, first metadata that maps logical addresses of logical data blocks to corresponding content identifiers, and second metadata that maps content identifiers to corresponding physical addresses of physical data blocks in the storage pool and maintains a reference count. During an add-a-node operation, the processors are configured to move from the existing nodes to the new node some of its physical data blocks, their content identifiers, and reference counts in the second metadata without accessing or altering the first metadata. A method is also disclosed to move a logical device from one node to another by de-activating the logical device's first metadata on the first node and activating and retrieving the logical device's first metadata on the second node.
