Abstract
The utility model discloses the direct interconnection device between a kind of MezzanineCard and Switch, mainly comprise: MezzanineCard, Switch, computing board and some connectors, described MezzanineCard one end is plugged on described computing board by connector, its other end is directly connected by connector with the port of described Switch, realizes the direct signal transmission between described MezzanineCard and Switch.This direct interconnection device no longer completes being connected between described MezzanineCard and Switch by slave board, connector quantity is subtracted to be a half, HW High Way cabling complexity significantly reduces, and has significantly improved stability and the integrality of high speed transmission of signals, has reduced manufacturing cost.
Description
Technical field
The utility model relates to signal transmitting apparatus, specifically the direct interconnection device between a kind of Mezzanine Card and Switch.
Background technology
In the design of server Mezzanine Card (interlayer card), the common practice is that the input/output port of Mezzanine Card is all inserted on computing board by connector; The switch of the various configurations models such as 8 ports, 18 ports, 36 ports, 108 ports, 216 ports, 324 ports, 648 ports that InfiniBand switch is produced containing Mellanox, simultaneously, Infiniband switch is inserted on slave board by high speed connector, is connected by slave board with the computing board that is inserted with mezzaine card by high speed connector again.As shown in Figure 1, mezzaine card is plugged on computing board by connector 1, connector 2, Switch(switch) be inserted on slave board by connector 5, connector 6, and slave board is connected by connector 3, connector 4 with the computing board that is inserted with mezzaine card.
Have like this two shortcomings: 1. terminal Switch(switch) and mezzaine card between be separated with several connectors, high speed signal loss is larger, signal wire length may overlength, is unfavorable for that signal keeps integrality; 2. connector is too much, has increased working equipment cost.
Utility model content
The weak point existing for prior art, provides the direct interconnection device between a kind of Mezzanine Card and Switch reasonable in design, simple in structure.
Direct interconnection device between a kind of Mezzanine Card described in the utility model and Switch, its technical scheme that solve the technical problem employing is: the direct interconnection device between described Mezzanine Card and Switch, cancel switch Switch and hang over the framework being just connected with computing board on slave board and by slave board, and change the connection of Mezzanine Card on computing board and design, make the high speed signal output port of Mezzanine Card no longer connect computing board, but be directly connected by connector with the port of switch Switch; Direct interconnection device between described Mezzanine Card and Switch, its framework mainly comprises: Mezzanine Card, Switch, computing board and some connectors, wherein, described Mezzanine Card one end is plugged on described computing board by connector, the other end of described Mezzanine Card is directly connected by connector with the port of described Switch, carries out the direct signal transmission between described Mezzanine Card and Switch.
The beneficial effect that compared to the prior art direct interconnection device between a kind of Mezzanine Card of the present utility model and Switch has is: the direct interconnection device between described Mezzanine Card and Switch, no longer complete being connected between described Mezzanine Card and Switch by slave board, the connector quantity using subtracts and is a half, HW High Way cabling complexity is significantly reduced, effectively improve between Switch and mezzaine card connector too much, the problem of loss of signal, stability and the integrality of high speed transmission of signals are significantly improved, reduce manufacturing cost.
Brief description of the drawings
Accompanying drawing 1 is the interconnection device block diagram between original Mezzanine Card and Switch;
Accompanying drawing 2 is the direct interconnection device block diagram between described Mezzanine Card and Switch.
Embodiment
Below in conjunction with the drawings and specific embodiments, the direct interconnection device between a kind of Mezzanine Card described in the utility model and Switch is described in further detail.
Direct interconnection device between a kind of Mezzanine Card described in the utility model and Switch, cancel switch Switch and hang over the framework being just connected with computing board on slave board and by slave board, and change the connection of Mezzanine Card on computing board and design, make the high speed signal output port of Mezzanine Card no longer connect computing board, but be directly connected by connector with the port of switch Switch.Direct interconnection device between described Mezzanine Card and Switch, its framework mainly comprises: Mezzanine Card, Switch, computing board and some connectors, wherein, described Mezzanine Card one end is plugged on described computing board by connector, the other end of described Mezzanine Card is directly connected by connector with the port of described Switch, carries out the direct signal transmission between described Mezzanine Card and described Switch; Direct interconnection device between this Mezzanine Card and Switch, improved connector between Switch and mezzaine card too much, the problem of loss of signal, effectively protected the integrality of signal transmission, also significantly reduced production cost simultaneously.
Embodiment:
Below by an embodiment, design content and the advantage of the direct interconnection device between a kind of Mezzanine Card described in the utility model and Switch are elaborated.
Direct interconnection device described in the present embodiment between Mezzanine Card and Switch, as shown in Figure 2, the main framework of the direct interconnection device between described Mezzanine Card and Switch comprises: Mezzanine Card, Switch, computing board and connector 1, connector 2, connector 3; Wherein, the high speed signal input port of described Mezzanine Card is plugged on described computing board by connector 1, the high speed signal output port of described Mezzanine Card is directly connected by connector 2, connector 3 with described Switch, carries out the direct signal transmission between described Mezzanine Card and described Switch.In the present embodiment, described computing board is chosen as the mainboard of computing machine.
Preferably, the high speed signal output port of the card of Mezzaine described in the present embodiment adopts the interface with switch Switch direct interconnection, can make described Mezzanine Card directly be connected by connector with described Switch; And, the high speed signal output port of described Mezzanine Card is plugged on described connector 2, described connector 2 is connected with described connector 3, be plugged on the port of described Switch by described connector 3, complete direct connection the between described Mezzanine Card and described Switch.
Direct interconnection device described in employing the present embodiment between Mezzanine Card and Switch, by connector 1, the high speed signal being transmitted by PCIE BUS imports described Mezzanine Card into, then pass through the high speed signal output port of described Mezzanine Card, and import in described Switch by connector 2 and connector 3.From the technical scheme of the direct coupling arrangement between this Mezzanine Card and Switch, the quantity of the connector adopting subtracts and is a half, the complexity of HW High Way cabling is significantly reduced, effectively improve the signal loss problem in high speed transmission of signals process, the integrality that has significantly improved signal transmission, has also significantly reduced manufacturing cost simultaneously.
Except the technical characterictic described in instructions, be the known technology of those skilled in the art.
