Abstract: A computer program product, system, and method to manage access to storage resources from multiple applications. A plurality of virtual controllers is generated in a host memory space. Each virtual controller includes at least one virtual namespace that maps to a physical namespace in a physical controller. Applications are assigned to the virtual controllers. For each application of the applications assigned one of the virtual controllers, a virtual submission queue is generated to communicate with the virtual controller assigned to the application. An Input/Output (I/O) request to a target virtual namespace in one of the virtual submission queues is added to a physical submission queue for the physical controller having the physical namespace for which the target virtual namespace was generated.

Abstract: Embodiments of the present disclosure relate to an electronic apparatus that includes a metadata generator, to generate an extents table (ET) that lists one or more extents pages (EPs), where an EP is a fixed size, and where the one or more EPs store one or more extents. An extent includes an allocation indication for a cluster in a memory device, where a number of the extents corresponds to a number of clusters of the memory device, where a subset number of the extents is stored in one of the one or more EPs, and where the subset number is based on the fixed size of the EP. The electronic apparatus further includes a metadata updater, to modify the allocation indication in the extent stored in the one of the one or more EPs, based on a corresponding change in an allocation of the cluster in the memory device.
