  • Patent number: 11669355
    Abstract: A system and method for providing dynamic information virtualization (DIV) is disclosed. According to one embodiment, a device includes a dynamic optimization manager (DOM), a process and memory manager (PMM), a memory, and a host device driver. The device starts virtual functions after booting to allow a virtual machine (VM) running a guest operating system to identify the virtual functions and load virtual drivers of the virtual functions. The PMM allocates a unified cache from the memory to facilitate coherent access to information from storage and network resources by the VM. The host device driver enables a guest process in the VM to access the information stored in the unified cache in a secure and isolated manner.

  • Patent number: 11567680
    Abstract: A method and system for dynamic storage scaling based on automatically parallelizing access of names and data across multiple nodes or micro object stores (MOSs) is provided. A dynamic storage scaling device cluster is provisioned for a particular level of parallelism (e.g., N MOSs) when the cluster is created. The N MOSs may initially reside in a few physical servers (e.g., one server). When the data distribution causes peak resource usage of the physical servers, new server(s) can be added. Some micro object stores (MOSs) are moved to the new physical server(s) through a meiosis process. The storage devices associated with the moved MOSs are unmounted from the original servers and mounted to the new server(s). The meiosis continues until the cluster grows to full capacity. The scaling is dynamic and efficient since no data copy is involved in the meiosis and the initial resource cost is optimized.
