Abstract:
1. An information system comprising: a first computer; a first storage apparatus; a first network apparatus coupled to the first computer and the first storage apparatus and providing a first fabric service; a second computer; a second storage apparatus; a second network apparatus coupled to the second computer and the second storage apparatus and providing a second fabric service; and a network that couples the first network apparatus and the second network apparatus, wherein: the first computer is configured to access only the first fabric service that is provided by the first network apparatus to which the first computer is coupled; the second computer is configured to access only the second fabric service that is provided by the second network apparatus to which the second computer is coupled; the first storage apparatus is configured to access the first fabric service that is provided by the first network apparatus to which the first storage apparatus is coupled, and the second fabric service that is provided by the second network apparatus to which the first storage apparatus is coupled via the first network apparatus and the network; the second storage apparatus is configured to access the second fabric service that is provided by the second network apparatus to which the second storage apparatus is coupled, and the first fabric service that is provided by the first network apparatus to which the second storage apparatus is coupled via the second network apparatus and the network; the first fabric service provided by the first network apparatus is allocated to a first virtual network; the second fabric service provided by the second network apparatus is allocated to a second virtual network; and wherein the first fabric service and the second fabric service do not communicate with each other; and wherein: the first computer provides a first virtual computer; the second computer provides a second virtual computer; the first virtual computer is configured to access the first fabric service provided by the first network apparatus; the second virtual computer is configured to access the second fabric service provided by the second network apparatus; and wherein: the first storage apparatus provides a first logical volume; the second storage apparatus provides a second logical volume; the first storage apparatus is configured to register the first logical volume into a function that is provided by a fabric service accessed by a virtual computer to which the first logical volume corresponds; the second storage apparatus is configured to register the second logical volume into a function that is provided by a fabric service accessed by a virtual computer to which the second logical volume corresponds; and wherein: when the first virtual computer provided by the first computer is moved to the second computer, the first virtual computer is configured to log out from a function provided by the first fabric service, and log into a function of the second fabric service that is provided by the second network apparatus coupled to the second computer to which the first virtual computer is moved; and a storage apparatus that provides a logical volume related to the first virtual computer is configured to log the logical volume out from the function of the first fabric service, and log into the function of the second fabric service that is provided by the second network apparatus connected to the second computer to which the first virtual computer is moved.
