Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following explains key terms appearing in the present invention.
The BMC executes a server remote Management controller, which is called Basebard Management controller in English. The method can perform operations such as firmware upgrading, machine equipment checking and the like on the machine in a state that the machine is not started. Fully implementing IPMI functionality in a BMC requires a powerful 16-bit or 32-bit microcontroller as well as RAM for data storage, flash memory and firmware for non-volatile data storage, providing basic remote manageability in terms of secure remote restart, secure re-power-up, LAN alerts and system health monitoring. In addition to the basic IPMI function and system operation monitoring function, the mBMC enables selection and protection of BIOS flash devices by storing the previous BIOS using one of 2 flash memories. For example, when the system cannot be started after the remote BIOS is upgraded, the remote administrator can switch back to the BIOS image that worked before to start the system. Once BIOS is upgraded, BIOS image can be locked to prevent virus from invading it.
The ipmitool is an ipmi platform management tool in a command line mode which can be used under a linux system, supports ipmi 1.5 specification (the latest specification is ipmi 2.0), and can realize functions of acquiring information of a sensor, displaying system log content, remotely turning on and off a network and the like. Ipmi (intelligent Platform Management interface), is a new generation of universal interface standard that enables hardware Management to be "intelligent". The IPMI may be used by a user to monitor physical characteristics of the server, such as temperature, voltage, fan operating conditions, power supply, and chassis intrusion. The maximum advantage of Ipmi is that it is independent of CPU BIOS and OS, so that the user can monitor the server by powering on the power supply whether in the power-on or power-off state. Ipmi is a standard of specification, in which the most important physical component is bmc (baseboard Management controller), an embedded Management microcontroller, which corresponds to the "brain" managed by the entire platform, through which Ipmi can monitor data of various sensors and log various events.
PCI-express (peripheral component interconnect express) is a high-speed serial computer expansion bus standard, originally named "3 GIO", which was proposed by Intel in 2001, to replace the old PCI, PCI-X and AGP bus standards. PCIe belongs to high-speed serial point-to-point double-channel high-bandwidth transmission, connected devices distribute independent channel bandwidth and do not share bus bandwidth, and the PCIe mainly supports functions of active power management, error reporting, end-to-end reliable transmission, hot plug, quality of service (QOS) and the like. PCIe is renamed to PCI-Express, which is called PCI-e for short, after being authenticated and issued by PCI-SIG (PCI Special interest group). Its main advantages are high data transmission rate and high development potential. PCI Express also has a variety of specifications, from PCI Express x1 to PCI Express x32, that meet the demands of low-speed devices and high-speed devices that will emerge in the future for a certain time. The PCI-Express interface is a PCIe 3.0 interface, has a bit rate of 8Gbps, which is about twice the bandwidth of the previous generation products, and includes a series of important new functions, such as transmitter and receiver equalization, PLL improvement, and clock data recovery, to improve data transmission and data protection performance.
FIG. 1 is a schematic flow diagram of a method of one embodiment of the invention. The execution subject in fig. 1 may be a firmware batch upgrade system for PCIe devices.
As shown in fig. 1, the method includes:

and step 140, acquiring the matched firmware file and the corresponding execution script from the database according to the model of the target server and the asset information of all the PCIe devices, and upgrading the firmware of the PCIe devices based on the matched firmware file and the corresponding execution script.
