Original Abstract Submitted
In part, the disclosure relates to a computer system. The system includes a network device, a storage device and at least two compute nodes, wherein one compute node is designated an active node and the other compute node is designated a standby node. Each compute node may include a dedicated memory with an isolated utility executive, an operating system memory, and a firmware reserved memory and the active node operating system memory further includes an availability driver, wherein the availability driver of the active node disables or suspends all processes that alter operating system memory and transfers all operation system memory of the active node to the operating system memory of the standby node, the isolated utility executive of the active node executes a code to generate an active validation array set of all operating system memory, the active validation array is then transferred to the standby node.
