Method and apparatus for deploying virtual hard disk to storage system

A system of deploying a VHD file to a storage apparatus, the system comprising:

• a storage apparatus;
• a host computer;
• and
• a network connecting the storage apparatus and the host computer;
• wherein the storage apparatus receives a VHD file and checks a block size of the VHD file based on a header of the VHD file;
• creates a virtual volume to provide a page size which is same size as the block size of the VHD file;
• and performs one of
• (A) copying contents of the VHD file to the created virtual volume by allocating one page of the created virtual volume for each block of the VHD file;
• or
• (B) formatting the created virtual volume with a virtual volume file system, and copying the VHD file to the formatted virtual volume.

A computer-readable storage medium storing a plurality of instructions for controlling a data processor to deploy a VHD file to a storage apparatus, the plurality of instructions comprising:

• instructions that cause the data processor to check a block size of the VHD file received by the storage apparatus based on a header of the VHD file;
• instructions that cause the data processor to create a virtual volume to provide a page size which is same size as the block size of the VHD file;
• and
• instructions that cause the data processor to perform one of
• (A) copying contents of the VHD file to the created virtual volume by allocating one page of the created virtual volume for each block of the VHD file;
• or
• (B) formatting the created virtual volume with a virtual volume file system, and copying the VHD file to the formatted virtual volume.
