摘要： Systems and methods presented herein provide for SSD data storage via PCIe controllers configured with NVMe interfaces. In one embodiment, a PCIe controller includes a plurality of buffers, a Dynamic Random Access Memory (DRAM) device, and an I/O processor operable to partition the DRAM device into a plurality of logical blocks. The controller also includes virtual function logic communicatively coupled to the logical blocks of the DRAM device and to the buffers. The virtual function logic is coupled to a host system through the I/O processor to process an I/O request from the host system to a logical block of the DRAM device, to retrieve data from the logical block to at least one of the buffers, and to transfer the data from the buffer to the host system.

摘要： A client device includes a memory and a processor cooperating therewith to boot the client device and connect to a provisioning server via a network. The processor receives a streaming virtual disk image from the provisioning server based on a virtual disk configuration, receives a virtual disk change notification from the provisioning server, and determines changes to the virtual disk configuration based on the virtual disk change notification. The memory and the processor cooperate with the provisioning server to change the streaming virtual disk image based on the determined changes to the virtual disk configuration and without rebooting the client device.

摘要： The embodiments of the present application provide a file storage method and an electronic device. The file storage method includes: receiving a file to be stored; determining a currently stored folder with a lowest storage priority after the storage space of a disk exceeds a preset threshold; and selecting and deleting a file from the determined folder, and storing the file to be stored in the disk. The embodiments of the present application can improve the utilization value of the storage space of the disk and further improve the performances of the video server; since the files with higher priority are retained, when called, these files do not need to be regenerated or obtained from other servers, thereby improving the utilization rate of system resources and also enhancing the experience of a video requested by the user.

摘要： A method for frame choosing in a computing system during a storage constraint condition is provided. The method includes calculating, with a processor, a use-grouped-threshold, comparing a number of available grouped frames to the calculated use-grouped-threshold, returning a decision to use a grouped frame in an event that the number of the available grouped frames exceeds the calculated use-grouped-threshold and returning a decision to use an above-the-bar frame in an event that the number of the available grouped frames is less than or equal to the calculated use-grouped-threshold.

摘要： Systems and methods are disclosed for swapping a memory page from memory to a swap device. An example system for swapping a memory page from memory to a swap device includes a memory to store one or more memory pages. The system also includes a swap device selector that receives an indication to swap out a memory page from memory to a swap device. The swap device selector identifies a memory group to which the memory page belongs and selects a swap device from a plurality of swap devices assigned to the identified memory group. The memory group identifies a plurality of applications having a common property. The system further includes a swap module that copies the memory page into the selected swap device.

摘要： A method, a system and a computer-readable medium for writing to a cache memory are provided. The method comprises maintaining a write count associated with a set, the set containing a memory block associated with a physical block address. A mapping from a logical address to the physical address of the block is also maintained. The method shifts the mapping based on the value of the write count and writes data to the block based on the mapping.

摘要： According to one embodiment, a method includes receiving a write request and determining a first portion of information associated with the write request. The method additionally includes determining a first location on a first disk to write the first portion of information and, based on the determined first location on the first disk, determining a second location on a second disk to write the first portion of information. The method further includes writing the first portion of the information to the first location on the first disk. The first location comprises an outer track of the first disk. The method further includes writing the first portion of the information to the second location on the second disk, the second location comprising an inner track of the second disk.

摘要： Embodiments relate to off-loading aspects of storage virtualization to storage hardware and modifying software to take advantage of hardware virtualization features. A co-design of hardware and software allows a filesystem to provide files such that indirection overhead normally needed to access the content of files can be bypassed while still managing the files as filesystem objects. A storage device manages and exposes a virtual volume which is used to store the content of a file. Virtual volumes can be initialized or populated so that virtual blocks therein align with device storage blocks. A virtual volume can be initialized and populated by parsing a virtual disk file to access virtual disk metadata, which is then used to determine and set features of the virtual volume.
