Abstract: A technique includes receiving information relating to wear of computer nodes. Based on the information relating to the wear, the technique includes ranking the computer nodes according to respective expected remaining lifetimes of the computer nodes. The technique includes, responsive to an event that corresponds to at least one of a spare computer node being added to the system or a given computer node being removed from the system, reconfiguring the system based on the ranking.

Abstract: In some examples, based on the information relating to the wear of physical memories in computer nodes of the distributed system, a system initiates a migration of a memory page from a first physical memory in a first computer node to a second physical memory in a second computer node. As part of the migration, the system updates a mapping between a first address space accessible by programs in the distributed system and a physical address space comprising memory locations in the physical memories.

Abstract: In accordance with example implementations, a process includes associating a secondary computer system with a primary computer system. The secondary computer system includes a first virtual machine, which is hosted by a secondary set of physical computer nodes. The primary computer system has a primary role, and the primary role corresponds to a minimum physical resource allocation. The secondary computer system is associated with a secondary role, and the second computer system is provisioned with a second physical resource allocation, which is less than the minimum physical resource allocation. The process includes, responsive to the primary computer system failing and without rebooting the secondary computer system, preparing the secondary computer system to take over the primary role. The preparation includes adding at least one physical computer node to the secondary set of physical computer nodes to cause the second physical resource allocation to meet or exceed the minimum physical resource allocation. The process includes, responsive to the primary computer system failing and without rebooting the secondary computer system, causing the secondary computer system to take over the primary role.

Abstract: Dynamic adaptive reconfiguration of a computing system includes receiving a request to remove a first node in a plurality of physical nodes. An operating system is executing collectively across the plurality of physical nodes, and an application is running on the operating system. It further includes in response to the request, and while the application is running, evacuating virtualized resources associated with the first node to one or more other nodes in the plurality of physical nodes. It further includes subsequent to the evacuation of the virtualized resources, removing the first node from the plurality of physical nodes.
