    摘要： In a method for accessing files in an electronic device, a Random Access Memory (RAM) disk is set-up to store the file system root of the electronic device. At least one file system to be mounted is discovered in the electronic device. Mount points are established on the RAM disk for each file system. Drive identifiers are assigned for each file system. A file access request comprising a first file name path comprising a drive identifier is detected. The drive identifier is mapped to a mount point and a second file name path based on the mount point and the first file name path is formed. Thereupon, a file is accessed using the second file name path in the electronic device.

    摘要： In a computer system having a storage controller that receives a read request or a write request, a processor is configured to send to an interface device either a read-support indication, which is an indication to execute either all or a portion of read processing for read-data of the read request, or a write-support indication, which is an indication for either all or a portion of write processing for write-data of the write request. Then, the interface device, in accordance with either the read-support indication or the write-support indication, is configured to execute either all or a portion of the read processing for the read-data, or all or a portion of the write processing for the write-data, and to send to a host computer either a first response to the effect that the read processing has been completed, or a second response that the write processing has been completed.

    摘要： A storage administrator may maintain location information in separate layers. A data storage system may identify the location of particular data by identifying the virtual location of data, such as the logical extent to which the data belongs. Object stores may maintain mappings of virtual locations to physical locations, such as mappings of extent identifiers to virtual storage objects and mappings of virtual storage objects to storage unit locations. When particular data is relocated to a new location, a storage administrator may update mappings used to translate virtual locations to physical locations, such as an extent-object mapping or an object-storage unit mapping. References to the virtual locations, such as references to logical extent identifiers, may not be updated in response to the relocation of data.
