Description
[technical field]
The present invention relates to communication technical field, be specifically related to a kind of long-distance management system based on hardware bottom layer and control device.
[background technology]
Server is used very general in life, enterprise, education sector, financial industry, telecommunications industry, military-political industries etc. all are widely used, the server of cybertimes is being taken on more and more important position, server generally is automatic operation, and it is on duty to need not the people, certainly sometimes needs server is managed and safeguards, but, if in the time of need to safeguarding, need to be in the action, that will expend a large amount of costs.For example when carrying out system upgrade to hundreds of server, IT administrative staff blink takes transport cost will be very huge, so need a simple effective method to manage all servers concentratedly, finish the variety of steps of execute-in-place, and system is recovered.
The real-time of Internet and long-distance transmissions function provide a good platform for us, just control signal can be transferred to all over the world based on ICP/IP protocol by Internet, if by an equipment can with the information of computer real-time send remote control terminal to, so just can pass through remotely administered server, to the management of long-range server with regard to in this locality every station server to be carried out field control the same.
Server is in operation and have control system quite simple to server maintenance in support, namely can realize by telemanagement software, but the server in station system outside in thousands of delays when machine or control system collapse, situation in the past all is administrative staff's maintenances that are on the scene, and the maintenance cost that expends like this is quite high.So can not only rest on the level of operating system to the management of server, the high layer software that can also allow it from bottom is by certain standard and hardware layer communication, and more complete, transparent manages server.
IPMI comes from the server field, and purpose is that the functions such as equipment control, transducer/incident management, user management, fan frame/power shelf management, remote maintenance are provided for server.IPMI has the characteristics such as standardization, management channels and service channel separate, abundant command set, fail safe height.
The characteristics that the management channels of IPMI separates with service channel make IPMI have high availability, make the power supply of IPMI subsystem independent, make IPMI not rely on business management system, even when the operation system fault, still have operability, and IPMI is based on the intelligent management platform interface of Internet, the core of IPMI is processor-server or baseboard management controller (BMC), it does not also rely on the processor of server, BIOS or operating system are come work, be independent in the extreme, be one in system, move separately without the proxy management subsystem, it just can be started working as long as BMC and IPMI firmware are arranged, and the BMC chip is one and is installed on the server master board, provides IPMI to support by BMC to server master board.The autonomous characteristic that IPMI is good has overcome in the past based on the suffered restriction of the way to manage of operating system, and it still can carry out the operations such as switching on and shutting down, information extraction in the situation that does not respond or do not load such as operating system.
In fact server maintenance is being needed to do following operation:
(1) possess the IPMI function: the health status of remote monitoring server, comprise event log, transducer reading and warning function in the system, the health status of server, in time reaction is to the manager.
(2) remote dummy memory function: when operating system collapse or damaged can't the reparation; need to reinstall operating system; when installing operating system; need to be all virtual to server end the CD-ROM drive of remote control terminal, floppy drive and USB device, just can realize the various types of operating systems of Remote Installation by the computer of control end.
(3) long-range KVM function: when control system is installed, need also to realize that long-range picture, mouse, keyboard are synchronous, just as in person before the server.
(4) after the remote server system outage, when switching on again, need by long-range cold start-up server, just look like oneself the frontal startup button by server is the same in person, the while is controlled the various functions such as not having to shut down, restart server in the situation of control system.
Make a long-distance management system have the IPMI function, must make controlled server master board support the IPMI function, and at mainboard the IPMB interface be arranged.When controlled server end does not have IPMI and baseboard management controller, just can not monitor the health status of remote service.
If server master board is not supported the IPMI function, also can't affect the realization of other function.
Have in the market the remote server administration function, and the remote management card of external PCI slot or only have the virtual memory function, or only have the KVM function, can realize that long-range cold start-up controlled terminal server does not almost have.
Need to control long-range server by remote control terminal comprehensively, at least must possess long-range KVM function, the remote dummy memory function, and abnormal conditions appear at remote server, can make server work by the cold start-up server, and realize Long-distance Control by the KVM-over-IP function.
Owing to be based on ICP/IP protocol when server is carried out telemanagement, control end searches out controlled terminal by the IP address, although the IP of controlled terminal fixes, controlled terminal has without limits control end, for example the IP address limitation or control software limitations, it is extremely important that this can manage remote server very easily to the IT manager, when long-distance management system need control end that specific software is installed or need control end and controlled terminal at same local area network (LAN), this just can not guarantee that the IT manager controls remote server fast whenever and wherever possible and easily.
For the IT manager, if control command is too complicated, this has just caused the applicable surface of this management system very narrow in addition.
In sum, former technology possesses following shortcoming at least:
1. function singleness, or can only realize the function of KVM, or can only realize the function of remote dummy storage, realize that simultaneously the remote on-off function needs the support of IPMI interface.
2. poor compatibility needs IPMI interface and corresponding BMC module support as realizing to the monitoring of server health status and warning function, can't realize the data monitoring of distance sensor for general personal computer.
3. after suddenly outage of remote terminal, when switching on again, can't realize the remote opening function.
