Techniques are disclosed relating to enabling virtual machines to access data on a physical recording medium. In one embodiment, a computing system provides a logical address space for a storage device to an allocation agent that is executable to allocate the logical address space to a plurality of virtual machines having access to the storage device. In such an embodiment, the logical address space is larger than a physical address space of the storage device. The computing system may then process a storage request from one of the plurality of virtual machines. In some embodiments, the allocation agent is a hypervisor executing on the computing system. In some embodiments, the computing system tracks utilizations of the storage device by the plurality of virtual machines, and based on the utilizations, enforces a quality of service level associated with one or more of the plurality of virtual machines.

Virtualization support for storage devices

A virtual address pager and method for use with a bulk erase memory is disclosed. The virtual address pager includes a page protection controller configured with a heap manager interface configured to receive only bulk erase memory-backed page requests for a plurality of memory pages. A RAM object cache controller is configured to store and bulk write data for a portion of the bulk erase memory. The page protection controller may have an operating system interface configured to generate a page memory access permission for each of the plurality of memory pages. The page protection controller may be configured to receive a virtual memory allocation request and generate the page memory access permission based on the virtual memory allocation request.

Virtual address pager and method for use with a bulk erase memory

An apparatus, system, and method are disclosed for servicing storage requests for a non-volatile memory device. An interface module is configured to receive a storage request for a data set of a non-volatile memory device from a client. The data set is different from a block of the non-volatile memory device, and may have a length different from a block size of the non-volatile memory device. A block load module is configured to load data of at least the block size of the non-volatile memory device. A fulfillment module is configured to service the storage request using at least a portion of the loaded data.

Servicing non-block storage requests

The illustrative embodiments described herein are directed to a system, methods, and computer program product, for network acceleration and efficient indexing for caching file systems. For example, the disclosed embodiments achieve (1) high compression rate, (2) low disk seeks, and (3) low memory pressure using by introducing novel features such as, but not limited to, multi-resolution chunking and intelligent load shedding. In addition, the disclosed embodiments introduces a family of HashCache policies that enable large size web caching with little or no use of main memory.
