Problems solved by technology

The traditional method is to either only monitor SAS and SATA disks without monitoring NVME disks; or use multiple I2C Switches and I2CExpander chips in a complex way, that is, BMC connects to I2C Switches (such as PCA9546) through a set of I2C, and I2C switches connect to SFF8639 interfaces To read NVME disk information, another group of I2C is connected to I2C Expander (such as PCA9555, PCA6408) chips to control

Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0043] The following takes the mid-board design with 3 SFF8639 interfaces and 1 SFF8680 interface as an example, assuming 2 NVME disks and 2 SAS disks. image 3 The specific embodiment of the present invention is further described:

[0044] Such as figure 1 Establish hardware connection, BMC module (disk monitoring and display module) is connected with CPLD or FPGA module through a set of I2C bus; SAS card (SAS / SATA transmission module) is connected with CPLD or FPGA module through SGPIO; CPLD or FPGA module is connected through I2C or SMbus Connect with interface SFF8639, and connect with interface SFF8639 and interface SFF8680 through GPIO.

[0045] At the same time, the SAS card (SAS / SATA transmission module) and the Retimer card module (NVME transmission module) establish high-speed data transmission with the disk by connecting the disk interface....

Abstract

The invention discloses a disk monitoring system and method. The system comprises a disk monitoring display module, a CPLD (Complex Programmable Logic Device) or FPGA (Field Programmable Gate Array) module, a disk interface module, an SAS (Statistical Analysis System)/SATA (Serial Advanced Technology Attachment) transmission module and an NVME transmission module. After the method and the system are started and electrified, a disk detection module carries out detection distinguishing on the type and the amount of connected disks. The system has the advantages that different types of disk states are monitored, monitoring functions are comprehensive and uniform, an implementation way is simple and reliable and clients can conveniently check.

Description

technical field [0001] The invention belongs to the technical field of servers, and in particular relates to a disk monitoring system and method. Background technique [0002] With the development of cloud computing technology and big data applications, the market's functional requirements for servers are becoming more and more comprehensive. It not only requires the capacity of traditional SAS and SATA mechanical disks to be increased, but also requires the use of SSDs, especially NVME SSDs, to achieve high-performance and low-latency applications. Therefore, there is an increasing demand for server systems that use SAS, SATA, and NVME disks in combination. [0003] The current interface type that supports SAS or SATA disks is SFF8680. If you need to support NVME disks, you need to replace them with SFF8639 interfaces, and you can read the VPD (Vital Product Data) of the disks through the I2C or SMbus interface in the SFF8639 interface to obtain the disk model, Manufactur...
