Description

A system for getting server screen output information

technical field

The invention relates to the technical field of servers, in particular to a system for acquiring server screen output information.

Background technique

At present, the core of the server management solution is a dedicated chip/controller (BMC), which does not depend on the server's processor, BISS or operating system to work. BMC is a typical complete embedded operating system, generally composed of processor, Flash (memory and storage), video processing equipment, network and special software. Dedicated software includes Intelligent Platform Management Interface (IPMI) and Virtual Keyboard and Mouse (KVM). BMC itself is a complete system with abundant surrounding equipment, which can run independently between servers, so users don’t need to worry about the state of the operating system, and can easily get machine output, important system logs and other information even if the system crashes. In the prior art solution, the BMC is connected to other hardware of the server as shown in FIG. 8 .

Disadvantages of existing server management solutions:

(1) Since BMC is an independent embedded system with many peripherals and independent software modules, the price and power consumption are relatively high. The cost of a BMC is about 20 US dollars, and the power consumption is about 3W. , taking 8 servers as an example, the hardware cost increases by $160, and the power consumption increases by 24W. For traditional servers, the price of the entire server is in the range of several thousand dollars, the power consumption is about 400W, and the BMC accounts for about 1% of the cost/power consumption of the overall system. Since server hardware is changing rapidly, especially for microservers, the reduction in cost and power consumption is very obvious. The price of a microserver CPU, motherboard and memory is about $100, and if a separate BMC is used, the cost will increase by 20%. The power consumption of a microserver CPU, motherboard and memory is about 20W. If a single BMC is used, the power consumption will increase by 15%.

(2) As an out-of-band monitoring and management solution, BMC can only automatically obtain some hardware-related log information through IPMI, but cannot automatically obtain certain operating status information of the system. You can only manually log in to BMC and open it manually. KVM looks at the final screen (image form) output. That is, it cannot be automated, and the amount of information obtained is very small.
