Method and apparatus for enabling a NAS system to utilize thin provisioning
InactiveUS20090077327A1Memory systemsInput/output processes for data processingFile systemDisk array
A NAS (network attached storage) controller managing file system data is configured for use in a storage system having thin provisioning capability. Physical storage capacity is used efficiently by making it possible for the NAS controller to identify to a disk array system having thin provisioning capability which segments of a thin provisioned volume are no longer in use. File system blocks or block groups no longer in use by the NAS controller are identified by the NAS controller. The NAS controller sends a release request to the disk array system specifying thin provisioning segments that correspond to the identified FS blocks or block groups. The release request instructs the disk array system to release chunks of physical storage capacity assigned to the specified thin provisioning segments so that the physical storage capacity can be made available for reuse in the disk array storage system.

Target application code is partitioned into target application code blocks, and related target application code blocks are combined into block groups and translated. Translated application code block groups are sized to comply with restrictions on branch instruction size. Upon selecting an application code block group for execution, a cache tag is used to determine if a corresponding translated code block group is available and valid. If not, the block group is translated and executed. Sequentially executed translated code blocks are located in adjacent portions of memory to improve performance when switching between translated code blocks. The emulator may use a link register of the host computer system to prefetch instructions and data from translated code blocks.
