Exemplary computer system architectures and methods are described. In some embodiments, a computer network comprises a computing engine including a plurality of compute nodes and a load balancer coupled to the computing engine and including a processor and a memory module. The memory module comprises logic instructions which, when executed by the processor, configure the processor to receive a connection request from a client computing device for computing services provided by one of the compute nodes, obtain, from the connection request, a session identifier associated with the request, and store the session identifier in a memory coupled to the load balancer.

Session persistence in dynamic node allocation computing environments

A blade computer system includes a plurality of client devices, a blade enclosure having a plurality of blades therein, and an allocation server configured to allocate and deallocate the blades to and from the client devices. The blade enclosure is configured to place individual ones of the blades into or out of a sleeping state responsive to network messages received from the allocation server.

Power conservation technique for blade computer systems

According to one embodiment, a system comprises a plurality of resources. The resources may be any limited-capacity computing resource that is capable of serving a computing demand of a resource user. A resource user refers to any entity which consumes computing capacity of a resource. The system comprises at least one power consumption profile associated with a respective resource user. The system also comprises at least one power management agent for measuring power consumption by ones of the plurality of resources in serving computing demands of the resource user, wherein said power consumption profile contains information based at least in part on the measured power consumption. The system also comprises at least one allocation agent for dynamically allocating the resource user to at least one of the resources based at least in part on the resource user's power consumption profile.

Systems and methods for determining power consumption profiles for resource users and using the profiles for resource allocation

In some embodiments, a computer network comprises a computing engine comprising a plurality of compute nodes and a load balancer coupled to the computing engine and coupled to a processor and a memory module, wherein the memory module comprises logic instructions which, when executed by the processor, configure the processor to receive, in the load balancer, a connection request from a first client computing device and a corresponding first persistence identifier for computing services provided by a first compute node managed by the load balancer, restore, on the first compute node, a stored computing session when the first persistence identifier is associated with the stored computing session, initiate, on the first compute node, a generic computing session when the first persistence identifier is not associated with any stored computing session, and assign the connection request from the first client computing device to the first compute node.

Restoring user states in dynamic computing environments

A blade enclosure includes a plurality of blades, an enclosure manager processing device and a bus coupling the enclosure manager processing device to each of the blades. Each blade has at least one power mode bit configured to be controlled by the enclosure manager processing device via the bus, and each blade is configured to cause itself to enter a working state or a sleeping state responsive to its at least one power mode bit.
