Abstract: A system including memory and a resource controller. The memory includes a first memgroup and a second memgroup, wherein the first memgroup comprises a first physical page mapped to a virtual page, and wherein the second memgroup comprises a second physical page. The resource controller is configured to receive a request to stop the first memgroup, instruct a memory power management subsystem to mark the first memgroup as stopped in response to receiving the request to stop the first memgroup, wherein no free pages are allocated from the first memgroup after the first memgroup is marked as stopped, remap the virtual page to the second physical page in response to the marking the first memgroup as stopped, and reduce power to the first memgroup in response to a determination that the first physical page is not mapped to the virtual page.

Abstract: A system and method of dynamically managing a power supply allocation for each one of the server blades in a blade server includes a blade server system having a blade chassis, multiple server blades coupled to the blade chassis, a power supply system coupled to the blade chassis, a chassis management module coupled to the blade chassis, wherein the blade chassis includes electrical and data communication interconnections between the server blades, the redundant power supply system and the chassis management module. The chassis management module includes computer readable media having program instructions for dynamically managing a power supply allocation for each one of the server blades.

Abstract: A fault zone definition mechanism groups components of an interconnect environment having a common point of dependence into a logical group defining a fault zone for the interconnect environment. The fault zone definition mechanism may be implemented in software, firmware or hardware, or a combination of two or more of software, firmware and hardware. A method for defining a fault zone is also disclosed.

Abstract: A distributed shared memory multiprocessor computer system utilizes page placement policies to reduce data access latencies. Pages of memory are allocated to nodes in a distributed shared memory multiprocessor computer system. A placement policy database is maintained which indicates a placement policy for each page in the system. Upon an access to a page, the placement policy corresponding to the accessed page is determined and the indicated policy is acted upon. A Migrate on Next Touch policy provides that the next access to a page with this policy will cause the page to migrate to the node of the accessing CPU. A Memory Follows Lightweight Process (LWP) policy ensures that pages within a given address range are always local to a specified LWP. A Migrate on Every Touch policy provides that pages within a given address range are migrated to an accessing CPU on every touch. A Replicate on Remote Touch policy provides for replication of a page in the memory of each accessing CPU's domain.
