In the motherboard design of server, there are two types of external connection modes for Baseboard Management Controller managing chip: management core
Piece carry network control chip itself (uses the channel RGMII -- Reduced Gigabit Media Independent
Interface simplify gigabit medium independent interface), by the shared network interface channel function at the network system Intel X540
Realization external connection (using the channel RMII -- it is independent that Reduced Medium Independent Interface simplifies medium
Interface).
The requirement of Baseboard Management Controller outband management is in the case where mainboard has been powered on, and no matter machine is in
Any state, outband management network necessarily require to keep unimpeded constantly.And the network chip for providing shared network interface channel is
With grid multiplexing a network interface card, grid in different start-up phases, network interface card itself can complete electrical chip self-test,
The movements such as PCIE channel initialization.In these action executing process, network card chip itself has the process of interruption, is bound to out
The problem of existing network share network interface passway suspension.
Summary of the invention
Technical assignment of the invention is to provide a kind of side using Baseboard Management Controller adjustment network interface card start-up mode
Method.
Technical assignment of the invention is realized in the following manner, a kind of to be started using Baseboard Management Controller adjustment network interface card
The method of mode, the specific method is as follows: the first step, utilizes the Baseboard Management Controller administration order tool of Baseboard Management Controller
Specification access network controller；
Second step, network controller electrifying startup；
Third step, the booting of system power supply key；
4th step, Baseboard Management Controller work, keeps network higher rate；
The holding of network chip is arranged by Baseboard Management Controller administration order tool for 5th step, Baseboard Management Controller
Physical connection function.
Preferably, the specific method is as follows:
1) Baseboard Management Controller participates in the work of X540 network interface card netinit；
2) using Intelligent Platform Management Interface tool make network interface card network rate maintain it is constant under the conditions of some；
3) using the shared network interface channel rate of Baseboard Management Controller setting network, make shared network interface channel
Network carrying out PCIe network initialization and the calling that drives during entering operating system, be able to maintain flank speed into
The transmission of row data.
Preferably,
When network interface card is Intel X540, the hardware signal pin R2 of X540 is MAIN_PWR_OK, by the electricity of the pin
It is flat to be revised as P3V3_AUX from P3V3_PCIE electricity；
In the specification of network chip, the register of " Keep phy link up En " is defined；
According to the definition in Intel specification, Baseboard Management Controller firmware is directed to different network interface cards, and setting keeps object
Manage the parameter of connection.
Compared to the prior art a kind of method using Baseboard Management Controller adjustment network interface card start-up mode of the invention, is led to
Cross above-mentioned hardware, the design optimization importing of software scenario utilizes bottom plate after the work of system boot noseplate Management Controller
The shared network interface channel rate of network is arranged in Management Controller, guarantees no matter shared network interface channel network is carrying out
Calling PCIe network initialization or driven during entering operating system is able to maintain flank speed and carries out data biography
It is defeated, to solve portions of client during os starting since suspension causes remotely principle to start startup item
Problem.
Detailed description of the invention
Attached drawing 1 is the effect before a kind of design optimization of method for adjusting network interface card start-up mode using Baseboard Management Controller
Figure；
Attached drawing 2 is the effect after a kind of design optimization of method for adjusting network interface card start-up mode using Baseboard Management Controller
Figure.
Specific embodiment
Embodiment 1:
A method of network interface card start-up mode is adjusted using Baseboard Management Controller:
The program accesses network-control using the Baseboard Management Controller administration order tool specification of Baseboard Management Controller
Device, after network controller electrifying startup, Baseboard Management Controller is arranged by Baseboard Management Controller administration order tool
The holding physical connection function of network chip guarantees network in the connectivity in each stages such as PCIE initialization, driving calling.
Since Baseboard Management Controller is outband management, the modification of firmware is also conducive in client to shipment
Product import improvement alternative, to not influence the service operation of client machine.
The function of the pin is when network detects that system is in shutdown state, and network can carry out net automatically
Card rate re-negotiates to vulgar state；The process of auto negotiation will cause the disconnecting of network, therefore should in hardware design
After the level of pin needs to be revised as P3V3_AUX. from P3V3_PCIE electricity to guarantee shutdown, the pin on network card chip
It is constantly in working condition.
According to the definition in Intel as above specification, BMC FW is directed to different network interface cards, and the ginseng of Keep phy link is arranged
Number, referring to table 1:
Table 1
According to the working principle of X540, the feelings that shared network interface channel network cannot interrupt at any time are realized
Condition, need to complete following design adjustment: 1) Baseboard Management Controller participates in the work of X540 netinit, utilizes intelligence
Platform management interface tool tool guarantees to change under the conditions of the network rate of X540 maintains some；It 2) is guarantee system network
The rate of network can support to maximum rate, need to X540 network carry out overall process high speed network rate setting.
The change of hardware signal: the hardware signal pin R2 of X540 is MAIN_PWR_OK, and the function of the pin is in net
When network detects that system is in shutdown state, network can carry out network interface card rate automatically, and to re-negotiate to vulgar state automatic
The process of negotiation will cause the disconnecting of network.Therefore the level needs of the pin are repaired from P3V3_PCIE electricity in hardware design
After P3V3_AUX. is changed to guarantee shutdown, the pin foot is constantly in working condition on network card chip.
The method of Baseboard Management Controller adjustment network startup defines " Keep phy in the specification of network chip
The register of link up En ", the function of the register is exactly: in network card chip in switching on and shutting down, if network card chip
Power state changes, can be by the way that the register is arranged, to keep the state of physical connection.
According to the definition of Keep Phy link up en defined in Intel as above specification, Baseboard Management Controller is solid
Part is directed to different network interface cards, and setting keeps the parameter of physical connection.It is imported by the design optimization of above-mentioned hardware, software scenario,
After system boot noseplate Management Controller Work, the shared network interface using Baseboard Management Controller setting network is logical
Road rate guarantees shared network interface channel network no matter in the initialization of progress PCIe network or in the mistake for entering operating system
The calling driven in journey is able to maintain flank speed and carries out data transmission, to solve portions of client in os starting mistake
In journey due to suspension cause can not long-range principle starting startup item the problem of.
The technical personnel in the technical field can readily realize the present invention with the above specific embodiments,.But it answers
Work as understanding, the present invention is not limited to above-mentioned several specific embodiments.On the basis of the disclosed embodiments, the technology
The technical staff in field can arbitrarily combine different technical features, to realize different technical solutions.
