| 发明名称 | Disk image introspection for storage systems | ||
| 摘要 | A method for disk image access in a storage system includes prefetching a disk image metadata structure. An input/output (I/O) request to the disk image is received. In response to the I/O request, a file system request is reconstructed by laying out the disk image, performing type-specific introspection on the disk image, and mapping data ranges in the disk image to blocks or files within the file system based on results of the introspection. | ||

| 主权项 | 1. A method for virtual machine disk image access in a storage system, comprising: prefetching a disk image metadata structure; receiving an input/output (I/O) request to the disk image; and in response to the I/O request, reconstructing a file system request by laying out the disk image, performing type-specific introspection on the disk image comprising determining disk image type and using a file system specific process for a particular type of file system located in the disk image for analyzing the disk image structure, wherein the I/O request is converted to an original file system request based on the disk image metadata structure, and a read or write request is converted to a lookup request. | ||
