Abstract: An example method involves receiving, at a first memory node, data to be written at a memory location in the first memory node. The data is received from a device. At the first memory node, old data is read from the memory location, without sending the old data to the device. The data is written to the memory location. The data and the old data are sent from the first memory node to a second memory node to store parity information in the second memory node without the device determining the parity information. The parity information is based on the data stored in the first memory node.

Abstract: A system and method is illustrated for comparing a target memory address and a local memory size using a hypervisor module that resides upon a compute blade, the comparison based upon a unit of digital information for the target memory address and an additional unit of digital information for the local memory size. Additionally, the system and method utilizes swapping of a local virtual memory page with a remote virtual memory page using a swapping module that resides on the hypervisor module, the swapping based upon the comparing of the target memory address and the local memory size. Further, the system and method is implemented to transmit the local virtual memory page to a memory blade using a transmission module that resides upon the compute blade.

Abstract: A method for communication between computing devices includes identifying the parameters of a data transfer between a source computing device and a target computing device and identifying communication paths between a source computing device and target computing device, in which at least one of the communications paths is a physical network. A communication path is selected for the data transfer. When a data transfer over the physical network is selected as a communication path, a nonvolatile memory (NVM) unit is removed from the source computing device and placed in a cartridge and the cartridge is programmed with transfer information. The NVM unit and cartridge are transported through the physical network to the target computing device according to the transfer information and the NVM unit is electrically connected to the target computing device.
