Solid recording device and method for accessing in real time and parallel processing

Abstract

The invention discloses a solid recording device and a solid recording method for accessing in real time and parallel processing. The solid recording device for accessing in real time and parallel processing comprises a solid recording system control card for accessing and parallel processing, a plurality of solid storage cards for accessing and parallel processing, and a single board computer, wherein the system control card is connected with acquisition and playback peripheral equipment through specific peripheral equipment communication interfaces, and is connected with one or more than one solid storage card which is provided with four groups of independent flash arrays and a controller thereof through multi-channel high-speed access communication interfaces; a reading data link and a writing data link which are independent of each other are established between the acquisition and playback peripheral equipment and any two groups of flash arrays on the solid storage card; the flash array controller performs multistage assembly line read/write operation; the solid recording method for accessing and parallel processing comprises the following steps: performing recording and playback operation on all hard wire parallel processing; accelerating the conversion from LBA (Logic Block Address) to PBA (Physical Block Address) by adopting equalization write and address quadratic mapping strategies; therefore, the aim of performing data recording and playback simultaneously at a high speed is achieved by the solid recording device and the solid recording method for accessing in real time and parallel processing.

Description

technical field [0001] The invention relates to the field of data storage, in particular to the field of solid-state recorders, in particular to a solid-state recording device and method for accessing real-time parallel processing. Background technique [0002] Existing data storage technologies include: open disk storage technology and closed recorder storage technology. [0003] Open disk storage technology, its typical products such as solid state disk, DAS / SAN / NAS disk array, etc., are often used for computer and server file system data storage, and generally use a single single board computer communication interface such as PCIe, SAT / SAS, FC , LAN, etc., the parallel access of multiple storage media has the characteristics of high burst rate, and the expansion is easy to realize, but it cannot meet the needs of continuous high-speed real-time access; and because the storage array is a single critical resource topology, recording and reading Operations cannot proceed co...

AI Technical Summary

Problems solved by technology

[0004] Closed recorder storage technology generally provides one or more external dedicated communication interfaces in addition to the single-board computer communication interface. Peripherals access data through the peripheral dedicated communication interface of the recorder. Reading does not require file system support, and has the characteristics of continuous real-time high-speed access, but the storage array structure is still a single critical resource topology, so it does not support parallel processing of access, and due to its closedness, speed and capacity Limited scalability
