Nonstop computing fabric arrangements

A system for providing a system for providing network communications organized using communities of interests defined by a common encryption key. IoT devices are located at the edge of a network while providing secure and isolated communications for its applications and data through a common network infrastructure. The system's functionality provides the IoT network with secure communications to obtain data from devices by host applications over public networks. The data may be organized and segmented in a manner that isolates and protects the data with only authorized applications gaining access the data to see its existence and read its contents.

One method includes allocating memory of one or more host computing systems in the computing fabric to a partition, the partition included among a plurality of partitions, the computing fabric including a hypervisor installed on the one or more host computing platforms and managing interactions among the plurality of partitions. The method includes defining an address range associated with the memory allocated to the partition, receiving a memory operation including an address within the address range, and, based on the memory operation including an address within the address range, issuing, by the hypervisor, an indication that the memory operation is occurring at an encrypted memory location. The method also includes performing the memory operation, and performing an encryption operation on data associated with the memory operation.

Methods and systems for managing reset of a physical function of an I/O device in a computing system are disclosed, where the physical function is included in a single-root PCI manager. One method includes maintaining a count of active virtual functions associated with the physical function included in the single-root PCI manager, and, upon determining that no active virtual functions are associated with the physical function, allowing the physical function to be reset within the single-root PCI manager. The method further includes while resetting the physical function, persisting a configuration memory space associated with the physical function, and associating the persisted configuration memory space with the physical function after the physical function is reset.

A reduced service partition system and method for a host computing device having a host processor and system resources including memory divided into most privileged system memory and less privileged user memory. The system includes a virtualization boot application that operates in the less privileged user memory and divides the host computing device into a resource management partition, at least one virtual service partition and at least one virtual guest partition.

Dynamic allocation and assignment of virtual functions within fabric

Embodiments of the present invention provide a virtualization infrastructure that allows multiple guest operating systems to run and communicate amongst each other within a host hardware partition. The host system is divided into distinct logical/virtual partitions and special infrastructure partitions are implemented to control resource management and to control physical I/O device drivers that are, in turn, used by operating systems in other distinct logical/virtual guest partitions. Host hardware resource management runs as a tracking application in a resource management 'ultravisor' partition, while host resource management decisions are performed in a higher-level command partition based on policies maintained in a separate operations partition. The ultravisor partition maintains the master database of the hardware resource allocations and serves as a command channel to accept transactional requests for assignment of resources to partitions while also providing individual read-only views of individual partitions to the associated partition monitors.

A virtualization infrastructure that allows multiple guest partitions to run within a host hardware partition. The host system is divided into distinct logical or virtual partitions and special infrastructure partitions are implemented to control resource management and to control physical I/O device drivers that are, in turn, used by operating systems in other distinct logical or virtual guest partitions. Host hardware resource management runs as a tracking application in a resource management 'ultravisor' partition, while host resource management decisions are performed in a higher level command partition based on policies maintained in a separate operations partition. Host hardware I/O management is implemented in special redundant I/O partitions. Operating systems in other logical or virtual partitions communicate with the I/O partitions via memory channels established by the ultravisor partion.

Virtual data center that allocates and manages system resources across multiple nodes

This invention teaches a method and system for a computer program to accomplish communication in a computer environment which is independent of the system upon which the program is executing. This computer environment constitutes both the machine on which the program is running and other machines with which there exists a communication path. A method by which a program can be written to achieve such communication without knowledge as to what machine will be on the receiving end of the communication is provided. Knowledge as to what low-level protocol will be used to connect separate machines is not required at the time the application is written.
