Server file management

A virtual hard drive (VHD) file manager system for a virtualized logical server cloud that interfaces virtualization software and a server cloud manager to manage VHDs for logical servers of the server cloud, comprising:

• a master repository that stores a plurality of master component files associated with at least one stored VHD, said plurality of master component files including at least one core file and at least one delta file;
• and
• a VHD file manager that enables copying of said master component files to deploy VHDs in the server cloud, that manages creation and storing of new delta files and corresponding VHDs in said master repository, and that generates and maintains meta information to maintain file relationship integrity between deployed and master component files.

A method of managing virtual hard drives (VHDs) of logical servers of a virtualized logical server cloud, comprising:

• storing each component file of at least one VHD created in the server cloud including its last leaf file;
• and
• generating and managing master meta information to identify each stored VHD and its corresponding component files and their relationships.
