[0003] The current transmission and storage of large-capacity data basically depends on the cache of the raid card controller. Due to the limited cache capacity of the current raid card, the maximum is only 512MB, which is relatively large compared to the current data volume of hundreds of GB. If the power is suddenly cut off during the transmission process, the data integrity cannot be maintained; at the same time, due to the high cache price of the raid card, the complicated cache wiring design, and strict design stability control, this raid card cache method cannot achieve low-cost large-scale Capacity application; on the other hand, since the cache of the raid card is in DRAM mode, that is, the data will be lost when the power is turned off. Changes may occur and have a certain impact on the stability of the data

Embodiment Construction
[0021] A kind of RAID design method based on SSD hard disk cache acceleration and backup of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0022] The present invention is based on the theoretical support of data cache scheduling to solve the problem that currently in the process of mass data transmission, the data cache basically depends on the DRAM mode of the RAID card, which cannot guarantee the stable transmission of server data. as attached figure 1 As shown, a RAID design method based on SSD hard disk cache acceleration and backup is now provided, and the specific process is as follows:
[0023] Step 1, the server processor obtains data through the PCIE interface, and the data refers to the data after calculation and processing;
[0024] Step 2. Build the transmission path between the processor data transmission PCIE interface and the SSD hard disk;
[0025] Step 3, decoding and converting the data transmitted b...

The invention provides an RAID (Redundant Array of Independent Disks) design method based on SSD (Solid State Drive) caching acceleration and backup. The design method comprises the specific processes as follows: a server processor acquires data through a PCIE (Peripheral Component Interface Express) interface, wherein the data refers to calculated and processed data; a transmission route is constructed between the PCIE interface for transmitting the data acquired by the processor and the SSD; the data transmitted by the PCIE is decoded and transformed; the data obtained from the step 3 is cached in the SSD; the data in the SSD is unloaded in an external storage; and when the system is power-off, the data is unloaded again and a prompt is given. Compared with the prior art, the design method ensures the real-time performance, the reliability and the stability of the data acquired by the server, achieves the stable and effective data storage and acceleration, and improves the server performance.
Description
technical field [0001] The present invention relates to the technical field of computer communication, specifically, it is a method to solve the problem that the data cache basically depends on the DRAM mode of the RAID card in the process of mass data transmission, which ensures the real-time performance, reliability and stability of the server data. , realize stable and effective data storage and acceleration of data, and improve the RAID design method of server performance. Background technique [0002] The speed of today's server processors is getting higher and higher, and processors with high computing performance are used more and more widely. While achieving high computing performance, in more cases it is necessary to store data after processor computing and network transmission. Especially at present, the data volume of a single file is gradually increasing, and it is necessary to maintain a large number of data channel link transmissions to complete the storage and...
