Description

Non-volatile memory solid state hard disk signal control system

The present invention relates to a solid-state hard disk control system, and more particularly to a non-volatile memory solid-state hard disk control system.

Generally speaking, the traditional Hard Disk Drive (HDD) uses the magnetic head to read and write data on the rotating disk. Therefore, in actual use, the speed of reading and writing data of the operating system often depends on the disk. Speed and interface transmission speed, and the common disk speed on the market is 7200 rpm, and the higher the number of revolutions can even reach 15000 rpm, but the speed of reading and writing still has its limit, but in order to effectively improve the reading and writing speed The existing technology has developed a solid state disk (SSD) made by using flash memory, which has a reading speed about three times that of a conventional hard disk, and the writing speed is about a conventional hard disk. 1.5 times, but the power consumption is much smaller than the traditional hard disk, and has the characteristics of no noise, vibration and low heat.

As mentioned above, when the solid-state hard disk was first introduced, it was mainly transmitted through the SATA (Serial Advanced Technology Attachment (SATA) interface according to the standard of the Advanced Host Controller Interface (AHCI). The hard disk uses the traditional hard disk (disk) transfer interface, so it is also affected by the delay caused by the storage control IC when processing the disk read and write, so although the SATA is 2.0 (bandwidth 3Gb / s, speed 300MB/s) evolved to 3.0 (bandwidth 6Gb/s, speed 600MB/s), but still can't meet the transmission capacity of solid state hard disk, so the transmission capacity of solid state hard disk is limited by the bandwidth limitation of the transmission interface.

In order to solve the problem of the bandwidth of the transmission interface, the existing solid state hard disk is turned into a solid state hard disk based on the Peripheral Component Interconnect Express (PCIe) standard, which is called a non-volatile memory (Non -Volatile Memory Express; NVMe)'s emerging standard SSDs to effectively utilize SSD capabilities; for example, PCIe 3 x8 specifications, for example, are 10 times faster than traditional SATA 3.0.

In other performances, compared to the AHCI standard, each command needs to read 4 scratchpads and cause a delay of about 2.5 microseconds. Since NVMe has simplified the operation mode, it is not necessary to read the scratchpad when executing commands. Therefore, it has the characteristics of low latency; in addition, NVMe can process up to 64,000 Command Queues at the same time, and each command column can contain up to 64,000 instructions, giving full play to the parallel read and write advantages of NAND Flash. Compared to the AHCI interface, only one Command Queues instruction sequence can be processed at the same time. Each instruction column can only contain up to 32 instructions. NVMe's Input/Output Perations Per Second (IOPS) is far better than ACHI.

In summary, although the existing NVMe solid state hard disk can provide extremely high transmission speed, the existing solid state hard disk does not resolve the hard disk state like the control module of the conventional hard disk, and the corresponding indicator light is sent. Bright, making it difficult for the user to recognize the operating status of the solid state drive.

In view of the fact that the control module of the existing non-volatile memory solid state hard disk does not have the function of resolving the state of the hard disk, the user cannot clearly recognize the state of the non-volatile memory solid state hard disk, and the user does not Is it easy to find a specific non-volatile memory solid state drive from multiple non-volatile memory solid state drives, even when installing a non-volatile memory solid state drive? Therefore, the inventor of the present invention invented a non-volatile memory solid-state hard disk signal control system to determine non-volatile memory by connecting components of a non-volatile memory solid-state hard disk. Whether the solid-state hard disk is faulty, and accordingly, the fault indicator light is illuminated, and the position indicator light corresponding to the non-volatile memory solid-state hard disk is illuminated by the user to know that the non-volatile memory solid-state hard disk is known. s position.

The present invention solves the problems of the prior art, and the necessary technical means is to provide a non-volatile memory solid-state hard disk signal control system, including a non-volatile memory (Non-Volatile Memory Express; NVMe) solid state hard A disc, a processor, and a controller. The non-volatile memory solid state hard disk system has a control module, and the control module is configured to transmit an operation signal and a hard disk position signal. The sub-processor is electrically connected to the control module by an internal integrated circuit (I2C) bus to receive the operation signal and the hard disk position signal, and the sub processor includes a plurality of universal inputs. The output (General Purpose I/O; GPIO) ports are electrically connected to an operation indicator, a position indicator, and a fault indicator to drive the operation signal. The operation indicator light is bright, and when detecting the failure of the non-volatile memory solid state hard disk, a fault signal is transmitted to the fault indicator, so that the fault indicator lights up when receiving the fault signal. The controller is electrically connected to the sub-processor, so that a user controls the sub-processor to drive the corresponding hard disk position indicator to be illuminated according to the hard disk position signal.

An auxiliary technical means derived from the above-mentioned necessary technical means is that the controller is a Platform Controller Hub (PCH). Preferably, the non-volatile memory solid state hard disk control system further comprises a motherboard, and the platform path controller is disposed on the motherboard.

An auxiliary technical means derived from the above-mentioned necessary technical means is that the non-volatile memory solid-state hard disk signal control system further comprises a backboard, and the sub-processor is disposed on the backboard.
