Abstract:
1. A method of migrating a block storage device between network locations, the method comprising: configuring a first block storage device interface at a first branch network location to access a first logical storage in a block storage device at a data center network location, wherein the data center network location is connected with the first branch network location via a wide area network; providing block storage access to a first storage client at the first branch network location via the first block storage device interface by retrieving storage blocks from the first logical storage in the block storage device via the wide area network; disabling the block storage access to the first storage client to prevent the first storage client from accessing the storage blocks from the first logical storage in the block storage device; configuring a second block storage device interface at a second branch network location to access the first logical storage in the block storage device at the data center network location, wherein the data center network location is connected with the second branch network location via the wide area network; providing block storage access to a second storage client at the second branch network location via the second block storage device interface by retrieving storage blocks from the first logical storage in the block storage device via the wide area network; and wherein disabling the block storage access to the first storage client comprises:
