Abstract:
A node interconnection apparatus includes a computing node, a resource control node, and a device interconnection interface connecting the computing node and the resource control node. Each of the computing node and the resource control node includes a processing unit and a storage unit, and the resource control node further includes a resource interface for connecting with a network storage device. The resource control node manages a storage resource of the network storage device, and when the computing node needs to start up, the resource control node obtains operating system startup information from the network storage device and provides the operating system startup information to the computing node. The computing node can start up without the need for storing startup information locally.
Abstract:
A resource management technology is disclosed that may be applied to a host, where the host includes a Central Processing Unit (CPU), an endpoint connected to the CPU, and an Input/Output (I/O) device connected to the endpoint. A method includes: allocating, by the CPU, a target endpoint to a target process, where a virtual device is disposed on the target endpoint; obtaining, by the target endpoint, a performance specification of the target process, and adjusting a performance parameter of the virtual device according to the performance specification, where the adjusted virtual device satisfies requirements of performance specifications of all processes that use the target endpoint; and when the target process needs to access a resource, obtaining, from the I/O device, a resource that satisfies the performance specification of the target process, and providing the obtained resource to the target process for use.
Abstract:
A multi-instance 2-Level-Memory (2LM) architecture manages access by processing instances having different memory usage priorities to memory having different performance and cost levels. The 2LM architecture includes a virtual memory management module that manages access by respective processing instances by creating memory instances based on specified memory usage priority levels and specified virtual memory sizes and defining policies for each usage priority level of the created memory instances. In response to a virtual memory request by a processing instance, the virtual memory management module determines whether a virtual memory size at a designated usage priority level requested by a processing instance can be satisfied by a policy of a created first memory instance and, if not, selects another memory instance that can satisfy the requested virtual memory size at the designated usage priority level and swaps out the first memory instance in favor of the other memory instance.

Embodiments provide a resource management technology that may be applied to a host, where the host includes a CPU, an endpoint connected to the CPU, and an I/O device connected to the endpoint. A method includes: allocating, by the CPU, a target endpoint to a target process, where a virtual device is disposed on the target endpoint; obtaining, by the target endpoint, a performance specification of the target process, and adjusting a performance parameter of the virtual device according to the performance specification, where the adjusted virtual device satisfies a total requirement of performance specifications of all processes that use the target endpoint; and when the target process needs to access a resource, obtaining, from the I/O device, a resource that satisfies the performance specification of the target process, and providing the obtained resource to the target process for use.
Abstract:
Embodiments of the application provide a node interconnection apparatus, a resource control node, and a server system. The node interconnection apparatus includes a computing node and a resource control node, and a device interconnection interface connecting the two. Each of the computing node and the resource control node comprises a processing unit and a memory, and the resource control node further comprises a resource interface for connecting with one or more storage devices. The resource control node manages storage resources of the storage devices, and when a storage resource is required by the computing node in performing a computing task, the resource control node allocates the storage resource in the storage devices for the computing node. The computing node can be powered off to save the energy, while the resource control node remains powered on, so that the access to the storage devices is not affected.
