Example Embodiment

[0014] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0015] The invention provides a blade memory control scheme based on Serial RapidIO interconnection technology. This solution uses Serial RapidIO interconnection technology as the connection protocol of the blade system, uses VPX3U form factor in structure, uses NAND FLASH as the storage medium, and uses FPGA as the core of blade memory control, thus forming a blade memory with a simple structure and complete functions. The memory has the characteristics of hot swap, low cost, high reliability and fast access speed, and can more conveniently and quickly use multiple pieces of blade memory to form a large-capacity blade storage system.

[0016] figure 1 It is a schematic diagram of the composition of the blade storage device of the present invention.

[0017] like figure 1 As shown, the blade memory of the present invention includes: an FPGA processor 102 an...

Abstract

The invention provides a blade storage device and relates to the field of data storage. The blade storage device comprises an FPGA processor and a storage array pool provided for a bus of a high-speed serial bus card; the FPGA processor comprises a high-speed serial interface processing unit and an NAND controller; the high-speed serial interface processing unit is connected with the bus of the high-speed serial bus card; the NAND controller is connected with the storage array pool. By the use of the blade storage device, the problems of low reliability, low access speed and low requirements on work environment are solved, and a blade storage is high in reliability, high in access speed and low in requirements on the work environment, and multiple blade storage devices can be quickly and conveniently made into a high-capacity blade storage system.

Description

technical field [0001] The invention relates to the field of data storage, and is applied in a real-time large-flow storage environment, in particular to a blade storage device. Background technique [0002] At present, the connection mode of commercially available blade storage devices mainly adopts parallel technology, and its data storage technology mainly adopts magnetic recording technology. According to the different connection methods, the internal interconnection technology of embedded system is mainly divided into parallel technology and serial technology. Parallel technology has been an important means of data transmission for many years, but its further development has encountered obstacles. First of all, since the premise of the parallel transmission method is to transmit signals with the same timing and receive signals with the same timing, it will be difficult to make the timing of data transmission synchronize with the clock if the clock frequency is increase...
