Abstract

A file management system includes a host computer having one or more virtual machines, a switching layer computer configured to manage a namespace map for the virtual machines in the host computer, and a central storage unit. The host computer is connected indirectly to the central storage unit through an in-band IO path that includes the switching layer computer and directly to the central storage unit through an out-of-band IO path. When a virtual machines issues a file operation, a file operation including a data operation is routed to the central storage unit along an out-of-band IO path and a file operation including a metadata operation is routed to the central storage unit along an in-band IO path that includes the switching layer computer.
