Embodiment
In order to the technical characterstic of clear explanation this programme, below by embodiment, and its accompanying drawing is combined, to this
Invention is described in detail.Following disclosure provides many different embodiments or example is used for realizing the different knots of the present invention
Structure.In order to simplify disclosure of the invention, hereinafter the part and setting of specific examples are described.In addition, the present invention can be with
Repeat reference numerals and/or letter in different examples.This repetition is that for purposes of simplicity and clarity, itself is not indicated
Relation between various embodiments are discussed and/or set.It should be noted that part illustrated in the accompanying drawings is not necessarily to scale
Draw.Present invention omits the description to known assemblies and treatment technology and process to avoid being unnecessarily limiting the present invention.
A kind of adapter for supporting OCPA standard interfaces provided below in conjunction with the accompanying drawings the embodiment of the present invention and switching
Method is described in detail.
The embodiments of the invention provide a kind of adapter for supporting OCPA standard interfaces, by adapter by mainboard
PCIE interfaces go out OCPA interfaces, meet the needs of client is for network with this.
As shown in figure 1, the adapter includes PCIE interfaces, OCPA interfaces and power module.The PCIE interfaces are used for
Mainboard is connected, the OCPA interfaces are used to connect OCPA network interface cards, by above-mentioned two interface, the PCIE that will can be drawn from mainboard
X8 signals are converted into OCPA standard interface signals, and signal link is provided for OCPA network interface cards；The power module will be drawn from mainboard
Power supply signal provide power supply for OCPA network interface cards.
Generally, OCPA interfaces need to use the STBY power supplys (standby power) on mainboard, but existing mainboard can not give OCPA
Interface provides 5V or 12V STBY power supplys, can only provide the CORE power supplys (system power supply) after main frame is opened.When main frame is in
Upper electricity but when being not keyed up state, mainboard can only provide STBY power supplys, can not provide CORE power supplys, if turned with OCPA interfaces
Connect card and use CORE power supplys, can cause and the network interface card for card docking of transferring electricity but in the case of being also not keyed up on main frame, Wu Fazheng
Often work.
But in actual use, network interface card electricity but in the case of being not keyed up on main frame, the external world is needed by the NCSI on network interface card
Inside (Network controller sideband interface, network controller side band interface) channel access main frame
BMC (Baseboard Management Controller, baseboard management controller), that is, need the electricity on main frame but be not keyed up
In the case of, network interface card energy normal work.Therefore in this case, STBY power supplys can only be used.
Therefore using the power boost circuit in the power module of adapter, the 3V3 STBY power supplys that will be drawn from mainboard
Signal, handled by boosting, change into 5V STBY power supply signals, to provide normal work with the OCPA network interface cards for card docking of transferring
Required power supply signal.
To realize the signal link between mainboard and OCPA network interface cards, it is necessary to draw to PCIE X8 interfaces and OCPA interfaces
Pin defines.OCPA is OCP standard interfaces, and the pin for having specification defines, but PCIE X8 interfaces are a high quick access that can customize
Mouthful, can be with self-defined signal pins.Therefore it is self-defined to the progress of PCIE X8 interfaces, to meet PCIE X8 interfaces and OCPA interfaces
Between signal communication.
The self-defined signal of PCIE X8 interfaces includes following sections：
The high speed signal part of PCIE X8 interfaces；
100MHz PCIE Clock, by PCIE X16 golden fingers being given to OCPA network interface cards from mainboard and being used as standard time clock makes
With；
PCIE_RST signals, adapter is given to from mainboard by PCIE X8 interfaces, for resetting；
NCSI signals, from the BMC of mainboard by the way that on PCIE X8 interfaces to adapter, network interface card is controlled for BMC.
PCIE X8 signal communications are used between the PCIE X8 interfaces and OCPA interfaces.
As shown in Fig. 2 it is PCIE X8 signal communications between adapter and mainboard and OCPA network interface cards.
By setting adapter, and set on adapter to PCIE X8 interfaces and OCPA interfaces, to PCIE X8 interfaces
Carry out self-defined, the PCIE X8 interfaces in adapter and OCPA interfaces have been subjected to signal communication, so as to which mainboard can control
OCPA network interface cards, realize the access of the OCPA standard network interface cards of multiple network speed, and are not necessarily limited to certain type of mainboard,
It is same to support OCPA network interface cards for the mainboard of non-standard interface, improve the versatility of server.
As shown in figure 3, the embodiment of the present invention additionally provides a kind of forwarding method for supporting OCPA standard interfaces：
PCIE X8 interfaces and OCPA interfaces are set on adapter, by above-mentioned two interface, will can be drawn from mainboard
PCIE X8 signals be converted into OCPA standard interface signals, provide signal link for OCPA network interface cards
The signal that the PCIE X8 interface pins of adapter are transmitted carries out self-defined, self-defined signal support OCPA interfaces,
It is self-defined by being carried out to PCIE X8 interfaces, to meet the signal communication between PCIE X8 interfaces and OCPA interfaces.
The PCIE X8 interfaces of adapter are connected into mainboard, OCPA interfaces connection OCPA network interface cards, by adapter by mainboard
PCIE interfaces go out OCPA interfaces, and dock OCPA network interface cards in OCPA interfaces, need of the client for network met with this
Ask.OCPA network interface cards speed can be any one in 1G, 10G and 40G.
The power supply signal drawn from mainboard is boosted, powered for OCPA network interface cards.OCPA network interface cards need to use 5V or
12V STBY power supplys, but due in actual use, network interface card electricity but in the case of being not keyed up on main frame, the external world needs to pass through network interface card
On NCSI channel access main frames inside BMC, that is, in the case of needing on main frame electricity but being not keyed up, network interface card can normal work
Make.Therefore in this case, STBY power supplys can only be used.And the STBY power supplys of mainboard are 3V3 STBY power supplys, it is therefore desirable to right
Power supply signal is boosted, to meet that OCPA network interface cards provide the supply voltage needed for normal work.
Wherein, self-defined signal includes：
The high speed signal part of PCIE X8 interfaces；
100MHz PCIE Clock, by PCIE X16 golden fingers being given to OCPA network interface cards from mainboard and being used as standard time clock makes
With；
PCIE_RST signals, adapter is given to from mainboard by PCIE X8 interfaces, for resetting；
NCSI signals, from the BMC of mainboard by the way that on PCIE X8 interfaces to adapter, network interface card is controlled for BMC.
Between mainboard and adapter, between adapter PCIE X8 interfaces and OCPA interfaces, between adapter and OCPA network interface cards
It is PCIE X8 signal communications.
The boosting is specially to utilize the power boost circuit in adapter, the 3V3 STBY power supplys that will be drawn from mainboard
Signal, handled by boosting, change into 5V STBY power supply signals, to provide normal work with the OCPA network interface cards for card docking of transferring
Required power supply signal.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
