Technical scheme does: its structure includes network switching card, its characterized in that: the one end of network switching card is provided with the NVME interface, and the other end is provided with four giga network interface, be provided with the main chip of exchange card between NVME interface and the four giga network interface, the main chip of exchange card is crossed the pin with the network switching cartoon and is connected.
Description
Technical field
The utility model relates to server, storage system I/O expansion technique field, specifically a kind of four gigabit networking switching cards based on the exploitation of NVME hard-disk interface.
Background technology
With the development of cloud computing application, the information-based every field covering society gradually.The routine work life of people is more and more exchanged by network, and web database technology is also in continuous increase.In order to the diverse requirements of cope with network, the scalability as the terminal server of network has had higher requirement, and the diversity requirements that how can meet present market develops the convenient external extended network switching card of a high universalizable.
The PCIE quantity of the CPU of current platform is all limited, and a lot of server all requires NVME hard disk when providing high efficiency virtualization applications now, in order to how the PCIE distributing to NVME hard disk is realized more applied environments by the highly compatible improving server.The diversity expansion that how can meet server external equipment is the technical problem being badly in need of at present solving.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of four gigabit networking switching cards based on the exploitation of NVME hard-disk interface, solves the problem of the diversity expansion that how can meet server external equipment.
The utility model solves the technical scheme that its technical problem adopts: a kind of four gigabit networking switching cards based on the exploitation of NVME hard-disk interface, comprise network exchange card, one end of described network exchange card is provided with NVME interface, and the other end is provided with four gigabit networking interfaces; Be provided with switching card master chip between NVME interface and four gigabit networking interfaces, switching card master chip is crossed pin with network exchange cartoon and is connected.
As preferably, described NVME interface connects hard disk backboard.
More preferably, described switching card master chip adopts 1350 network chips.
Compared to the prior art a kind of four gigabit networking switching cards based on the exploitation of NVME hard-disk interface of the present utility model, have following beneficial effect:
1, the utility model adopts NVME standard hard drive interface generality high; Support the gigabit network interface of 4 standards, I/O favorable expandability; Outward appearance designs based on 2.5 inches of NVME hard disk chi inches, supports that hot plug can realize convenient exchange with hard disk;
2, the utility model effectively can increase the plug-in scalability of mainboard; The quick-replaceable of expansion card and NVME hard disk can be realized according to system configuration in hard disk position, improve the public property of module, reduce R&D costs.
The utility model have reasonable in design, structure simple, be easy to the features such as processing, volume are little, easy to use, one-object-many-purposes, thus, have good value for applications.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Accompanying drawing 1 is a kind of structural representation of the four gigabit networking switching cards based on the exploitation of NVME hard-disk interface.
In figure: 1, NVME interface, 2, switching card master chip, 3, four gigabit networking interfaces, 4, network exchange card.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of four gigabit networking switching cards based on the exploitation of NVME hard-disk interface of the present utility model, its structure comprises network exchange card 4, and one end of network exchange card 4 is provided with NVME interface 1, and the other end is provided with four gigabit networking interfaces 3; Be provided with switching card master chip 2 between NVME interface 1 and four gigabit networking interfaces 3, switching card master chip 2 is connected by pin with network exchange card 4.NVME interface 1 connects hard disk backboard.Switching card master chip 2 adopts 1350 network chips.
Network exchange plate connects hard disk backboard by standard NVME interface 1, power board master chip 2 adopts I350 chip external-connected port to be four gigabit standard RJ45 network interfaces, this network exchange card form is 2.5 inch hard forms of standard, can be fixed on and the front handlebar of present hard disk support bracket (be changed to front I/O catch) by present hard disk support bracket realizing hard disk position and expansion card position can quick-replaceable.
According to the definition of NVME hard-disk interface line sequence, extension of network card end, E7, E8 two PIN connect 100MCLK signal, E13, E14; S20, S21; S26, S27; E20, E21 connect the RX end of PCIE respectively, E10, E11; S17, S18; S23, S24; E17, E18 connect the TX end of PCIE respectively, and the SAS/SATA holding wire that standard interface connects does not need so unsettled on network exchange plate.
Because the power supply on the hard-disk interface of standard does not have 3.3V, 12V and 5V, wherein 12V directly can change the P1.0V main power source needed for I350, and the power supply of other 3.3V needs 5V conversion, so network exchange plate needs newly-increased 3.3V modular converter.
After NVME interface PCIEX4 is out changed by I350 chip, 4 RJ45 interfaces of connection standard get final product transmission network signal, just can realize four gigabit networking switching cards.
By embodiment above, described those skilled in the art can be easy to realize the utility model.But should be appreciated that the utility model is not limited to above-mentioned embodiment.On the basis of disclosed execution mode, described those skilled in the art can the different technical characteristic of combination in any, thus realizes different technical schemes.
