摘要： An apparatus, system, and method are disclosed for sharing a device between multiple hosts. The apparatus, system, and method include an RDMA setup module and an RDMA execution module. The RDMA setup module prepares a solid-state storage controller for an RDMA operation to transfer data of a file or of an object between the solid-state storage controller and a requesting device in response to a storage request. The storage request may be substantially free of the data, and the solid-state storage controller may control a solid-state storage via a storage input/output (“I/O”) bus. The solid-state controller controls storage of data in the solid-state storage, and the requesting device is connected to the solid-state controller through a computer network. The RDMA execution module executes the RDMA operation to transfer the data between the requesting device and the solid-state storage controller.

摘要： An apparatus, system, and method are disclosed for servicing object requests within a storage controller. An object request receiver module is included that receives an object request from a requesting device. The object request is received by the storage controller and directed at a data segment of an object managed by the storage controller. The storage controller stores the data segment in a data storage device coupled to the storage controller. A parsing module is included that parses at least one command from the object request. A command execution module is included that executes the at least one command parsed from the object request. An object index module is included that creates an object entry in an object index in response to the storage controller storing the data segment of the object. The object entry includes a mapping between a logical identifier of the object and one or more physical addresses corresponding to where the storage controller stored one or more data packets created from one or more data segments of the object and metadata packets created from object attributes of the object.

摘要： An apparatus, system, and method are disclosed for caching data on a solid-state storage device. The solid-state storage device maintains metadata pertaining to cache operations performed on the solid-state storage device, as well as storage operations of the solid-state storage device. The metadata indicates what data in the cache is valid, as well as information about what data in the nonvolatile cache has been stored in a backing store. A backup engine works through units in the nonvolatile cache device and backs up the valid data to the backing store. During grooming operations, the groomer determines whether the data is valid and whether the data is discardable. Data that is both valid and discardable may be removed during the grooming operation. The groomer may also determine whether the data is cold in determining whether to remove the data from the cache device. The cache device may present to clients a logical space that is the same size as the backing store. The cache device may be transparent to the clients.

摘要： An apparatus, system, and method are disclosed for efficiently mapping virtual and physical addresses. A forward mapping module uses a forward map to identify physical addresses of data of a data segment from a virtual address. The data segment is identified in a storage request. The virtual addresses include discrete addresses within a virtual address space where the virtual addresses sparsely populate the virtual address space. A reverse mapping module uses a reverse map to determine a virtual address of a data segment from a physical address. The reverse map maps the data storage device into erase regions such that a portion of the reverse map spans an erase region of the data storage device erased together during a storage space recovery operation. A storage space recovery module uses the reverse map to identify valid data in an erase region prior to an operation to recover the erase region.

摘要： An apparatus, system, and method are disclosed for bad block remapping. A bad block identifier module identifies one or more data blocks on a solid-state storage element as bad blocks. A log update module writes at least a location of each bad block identified by the bad block identifier module into each of two or more redundant bad block logs. A bad block mapping module accesses at least one bad block log during a start-up operation to create in memory a bad block map. The bad block map includes a mapping between the bad block locations in the bad block log and a corresponding location of a replacement block for each bad block location. Data is stored in each replacement block instead of the corresponding bad block. The bad block mapping module creates the bad block map using one of a replacement block location and a bad block mapping algorithm.

The reverse map maps the data storage device into erase regions such that a portion of the reverse map spans an erase region of the data storage device erased together during a storage space recovery operation. A storage space recovery module uses the reverse map to identify valid data in an erase region prior to an operation to recover the erase region.
摘要翻译：公开了用于有效地映射虚拟和物理地址的装置，系统和方法。前向映射模块使用转发映射来从虚拟地址识别数据段的数据的物理地址。在存储请求中识别数据段。虚拟地址包括虚拟地址空间内的离散地址，虚拟地址稀疏地填充虚拟地址空间。反向映射模块使用反向映射来确定物理地址的数据段的虚拟地址。反向映射将数据存储设备映射到擦除区域，使得在存储空间恢复操作期间，反向映射的一部分跨越数据存储设备的擦除区域被一起擦除。在恢复擦除区域的操作之前，存储空间恢复模块使用反向映射来识别擦除区域中的有效数据。
