Abstract
A system and apparatus intermediates between a centralized remote file service and several distributed virtual machine data center servers. When several file blocks are committed by applications running in virtual machines, they are aggregated together into a fewer number of file write operations to exploit the parallelism of multi-disk arrays. Requests for frequently retrieved file blocks are redirected to the location of the freshest retention. Each data center has a non-transitory file block store locally attached which provides images of virtual machines, applications, and data. Each file block librarian provides a file system view to each virtual machine. Several Virtual Machine Data Centers are coordinated by a tracker that locates, redirects, and retrieves any file block of any version of any file within its name space.
