Description
Technical field
The utility model relates to allocation of computer expansion field, specifically provides a kind of I/O to expand module.
Background technology
Computing machine is instrument indispensable in daily life, along with the development of society, more and more higher to the performance requirement of computing machine.In order to meet the demand to computing power, the server development of computing machine, from desk-top server to rack-mount server again to blade server, develops again fusion architecture blade server recently, and the performance of computing machine is significantly promoted.But only improve the needs that server architecture can't meet some special dimension, usually also need to expand server configuration.
The patent No. is disclose a kind of multi-functional I/O expansion card in the patent documentation of CN202331281U.But
Be that this multi-functional I/O expansion card will be installed on the PCIe slot of server master board, the blade server that PCIe slot is few use there is certain limitation; And the radiator fan that will take server system during the work of this I/O expansion card dispels the heat, and can affect the steady operation of original system to a certain extent.
Summary of the invention
Technical assignment of the present utility model is for above-mentioned the deficiencies in the prior art, provides a kind of structure simple, reasonable in design, and the I/O saving system space expands module.
For achieving the above object, the utility model provides following technical scheme: a kind of I/O expands module, comprise I/O expansion board, also comprise fixed support and radiator fan, described I/O expansion board is arranged on fixed support inside, and I/O expansion board being provided with two PCIe slots that correspondence system front end calculates blade, described radiator fan is arranged on support bracket fastened insertion end.
Two of difference correspondence system front end, two PCIe slots calculate blade nodes, achieve two and calculate module expanded by blades share and access to I/O.Although two calculate blade to I/O expansion module is share and access, but design isolated as follows can be adopted when the PCIe data access of reality: the signal in each PCIe slot shares 3 groups, PCIe data-signal, RWR_EN power control signal and GPIO & Present logic control signal respectively, these three groups of signals are all by dorsulum and the computing node of blade system, the access of the signal in a corresponding PCIe slot of calculating blade, fully ensures the security of data.The blade system that is designed to of share and access module saves dimensional space.Described radiator fan is preferably the fan of independently 40x28 specification, under guaranteeing that I/O expands the normal situation of module data communication, there is provided heat radiation to ensure for I/O expands the PCIe equipment that module is arranged in pairs or groups, do not occupy the radiator fan of existing system, ensure that the stable operation of system.Described I/O expands module and integrates shared I/O expanded function and independent heat sinking function, realizes the transmission alone of power supply signal, data-signal and supervisory signal.
As preferably, described support bracket fastened outer end is provided with handle, and convenient operation person expands module to I/O and inserts or extract operation.
As preferably, described support bracket fastened two side plates are " recessed " character form structure.When being designed with of " recessed " character form structure is beneficial to the PCIe equipment work in PCIe slot, heat scatters and disappears.
Compared with prior art, I/O expansion module of the present utility model has following outstanding beneficial effect:
(1) two PCIe slots in described I/O expansion board, can simultaneously for two physical aspects of blade system front end independently calculate the I/O expansion that blade node provides shared, share and access I/O expands module and is designed to merge the dimensional space that blade system saves structure;
(2) independently radiator fan design, need not take the system radiating fan in blade system, also can not have an impact to other radiating modules, and independence is strong, ensures the stable operation of system;
(3) the independent handle design on fixed support, convenient operation person inserts module or extracts operation.
Accompanying drawing explanation
Fig. 1 is the structural blast figure that I/O described in the utility model expands module;
Fig. 2 is the logical design schematic diagram of described I/O expansion board.
Wherein, 1. fixed support, 2.I/O expansion board, 3. radiator fan, 4. handle, PCIex16slot.PCIex16 slot, BladeN, BladeN+2. calculate blade node, PCIe3.0x8.PCIe data-signal, RWR_EN. power control signal, GPIO & Present. logic control signal.
Embodiment
Below in conjunction with drawings and Examples, module is expanded to a kind of I/O of the present utility model and is described in further detail.
In the utility model, when not doing contrary explanation, the noun of locality such as " upper and lower, left and right " of use typically refers to reference to upper and lower, left and right shown in the drawings; " inside and outside " refers to profile inside and outside relative to each parts itself.
Embodiment
As shown in Figure 1, I/O of the present utility model expands module, forms primarily of fixed support 1, I/O expansion board 2 and radiator fan 3.Two side plates of fixed support 1 all adopt " recessed " character form structure to design.Radiator fan 3 is fixed on the insertion end of fixed support 1, provides heat radiation to ensure for I/O expands the PCIe equipment that module is arranged in pairs or groups.The outer end of fixed support 1 is fixed with handle 4, conveniently expands module to I/O and inserts or extract operation.I/O expansion board 2 is fixed in fixed support 1, and I/O expansion board 2 is provided with the slot (as shown in Figure 2) of two PCIex16, is used for the PCIe equipment of collocation standard.One of correspondence system front end, each PCIe slot calculates blade, is respectively each calculating blade and provides independently PCIe expansion.Can support that in fusion architecture blade system 4 I/O expand module.
The logical design that I/O described in the utility model expands module is:
(1) I/O being expanded module is placed in fusion architecture blade server, and the calculating blade Node B ladeN of difference correspondence system front end, two PCIex16 slots and BladeN+2(as shown in Figure 2);
(2) PCIex16 slot shares PCIe data-signal, RWR_EN power control signal and GPIO & Present logic control signal, and these three groups of signals are all communicated with computing node by the dorsulum of blade system;
(3) PCIe data-signal adopts the data transfer signal of PCIe3.0x8, drawn by processor on computing node and be connected with I/O expansion board, be responsible for the Communication Control of concrete data when collocation PCIe equipment, realize the data communication between PCIe equipment and computing node and access;
(4) PWR_EN signal is Low level effective, be used for realizing calculating blade node to power to PCIe slot corresponding in I/O expansion board, during acquiescence, this signal is in high level, when blade system has detected that I/O expands module insertion, PWR_EN signal is dragged down, now the calculating blade of front end will be expanded module to I/O and powers, and the electric power provided obtains PCIe equipment use for radiator fan 3 and extrapolation;
(5) GPIO & Present signal is logic control signal, acquiescence GPIO & Present signal is effectively high, can drag down by GPIO & Present signal when I/O expands when module inserts, systems axiol-ogy just thinks that when GPIO & Present signal is low having I/O to expand module inserts, drag down with by PWR_EN signal, I/O expands module and starts to be powered, and can be learnt the information of the concrete PCIe equipment inserted by GPIO & Present signal blade computing node.
Above-described embodiment, just the utility model more preferably embodiment, the usual change that those skilled in the art carries out within the scope of technical solutions of the utility model and replacement all should be included in protection domain of the present utility model.
