  • Patent number: 11163463
    Abstract: A virtual volume is initially provided from a first storage appliance within a cluster of storage appliances by providing access to the virtual volume over a data path between a host computer and a protocol endpoint hosted on the first storage appliance, based on an initial binding between the virtual volume and the protocol endpoint hosted on the first storage appliance. A rebind request is conveyed to the host computer, and in response to receiving a bind request for the virtual volume, a new binding is created between the virtual volume and a protocol endpoint hosted by the second storage appliance. The virtual volume is subsequently provided from the second storage appliance by providing the host computer with access to the virtual volume over a data path between the host computer and the protocol endpoint hosted on the second storage appliance based on the newly created binding.

  • Patent number: 8058882
    Abstract: To characterize an electrical cable that is deployed in a well, a voltage input is applied to the electrical cable at an earth surface location, where the well extends from the earth surface location. A current response resulting from the voltage input is measured at the earth surface location. At least one parameter of the electrical cable is computed according to the measured current response.
