Abstract
A system includes an interconnect, processing cells connected to the interconnect, the processing cells containing corresponding cache memories and corresponding virtual machines, and a storage cell connected to the interconnect. The storage cell stores data portions that correspond to different ones of the processing cells, and the data portions are owned by individual ones of the processing cells to enable data communication over the interconnect without cache coherency support. A first and second of the processing cells are configured to migrate a virtual machine from the first processing cell to the second processing cell, where the migrated virtual machine in the second processing cell is configured to retrieve virtual machine data from a corresponding one of the data portions in the storage cell.
