一种实现NVME硬盘点灯的方法及系统
摘要：
本发明提供了一种实现NVME硬盘点灯的方法及系统，在CPU与NVME硬盘之间增加PCIE Switch芯片，扩展出更多数量的NVME硬盘端口，连接更多的NVME硬盘，并开发系统应用层硬盘指示灯的控制命令，将此命令包含在PCIE Switch芯片的驱动包内，CPU与PCIE Switch之间通过PCIE总线传递硬盘状态信息和硬盘点灯信息，硬盘点灯信息由PCIE Switch的I2C总线通过CPLD解析出对应的硬盘指示灯控制信息，在硬盘故障时点亮指示灯。通过本发明NVME硬盘点灯，解决了限制NVME硬盘的数量的问题，可根据产品需求搭配相应硬盘数量，省略每个NVME硬盘连接上一级设备的端口硬件线路上地址PIN，降低设计复杂度，解除了PIN对硬盘数量的限制。
摘要（英）：

The invention provides a method and a system of realizing NVME hard-disk lighting. A PCIE Switch chip is added between a CPU and NVME hard-disks, and a greater number of NVME hard-disk ports are obtained by expansion to connect the more NVME hard-disks; hard-disk indicator light control commands of a system application layer are developed, and contained in a drive package of the PCIE Switch chip;and hard-disk status information and hard-disk lighting information are transmitted between the CPU and the PCIE Switch through a PCIE bus, the hard-disk lighting information is sent by an I2C bus ofthe PCIe Switch and parsed through a CPLD to obtain corresponding hard-disk indicator light control information, and an indicator light is lit when the hard disk fails. Through the method and the system of NVME hard-disk lighting of the invention, the number limit problem of the NVME hard-disks is solved, a corresponding hard-disk number can be matched according to product requirements, an addressPIN on a port hardware line connecting each NVME hard disk to upper-level equipment is omitted, design complexity is reduced, and limits of the PIN on the hard-disk number are removed.
