Description

A kind of computer motherboard interface switching device

Technical field

The utility model belongs to computer realm, relates in particular to a kind of computer motherboard interface switching device.

Background technology

Continuous development along with infotech, day by day enriching of content of multimedia, server (Server) or PC (Personal Computer, PC) file that need store, multimedia files such as audio frequency and video, especially HD video are more and more, and file size is also increasing, although the memory capacity of computer-readable storage medium (as hard disk) is increasing, but still can not satisfy users' demand.Therefore, more user solves this problem by insert a plurality of hard disks in computer host box.But, general computer motherboard has only four Serial Advanced Technology Attachment interfaces (Serial Advanced Technology Attachment at most, SATA), insert if desired and surpass four fast hard disks, then need be by using expansion card, (Pedpherd Component Interconnect-Express, PCI-E) interface reaches the purpose that expands more SATA interfaces to take peripheral element expansion on the mainboard.

Yet the computer host box size is certain, this scheme of the prior art, advantage is to insert conveniently, but there is very big deficiency in this mode, not only will take the PCI-E interface, and relatively take limited space in the mainframe box, thereby be unfavorable for heat radiation in the mainframe box.

The utility model content

Technical problem to be solved in the utility model is being, at hard-disk interface on the mainboard in the prior art very little, and expand the defective that hard-disk interface takies big mainframe box space and poor radiation by expansion card in the prior art, provide a kind of and can in the cabinet finite space, not take the mainboard interface conversion equipment that expansion card just can be arranged many hard disks.The technical scheme that its technical matters that solves the utility model adopts provides a kind of computer motherboard interface switching device, and described device comprises:

Industry MINI SAS interface module is used for connecting respectively 4 SATA interfaces on the computer motherboard;

SAS extended chip module is used to receive the data-signal of 4 SATA interface inputs from the mainboard and expands to 16 groups of data-signals through treatment conversion; And

The SATA output interface module is used to export described 16 groups of data-signals through the treatment conversion expansion.

In above-mentioned mainboard interface conversion equipment, described MINI SAS interface is that 4 SATA combination of interfaces are a kind of standard interface of an interface, and described consensus standard is SFF-8087.

In above-mentioned mainboard interface conversion equipment, described each SATA interface transmits the data-signal of coming in to be passed through after processing, the conversion, and the data-signal of output is 4 groups of SATA data-signals.

In above-mentioned mainboard interface conversion equipment, described device also comprises the SGPIO control chip of supporting twin wire serial bus interface and general serial input/output bus (SGPIO) function.

In above-mentioned mainboard interface conversion equipment, described device also comprises the LED of the duty that is used to show hard disk.

The utility model is by expanding to 16 SATA interfaces with 4 SATA interfaces on the mainboard, and need not to use expansion card, do not take peripheral element extension interface (Pedpherd Component Interconnect-Express, PCI-E), make and to arrange many hard disks in the cabinet, and occupy little space, avoided taking more space and the problem that influences heat radiation, thereby effectively utilized the space in the mainframe box, also had better radiating effect.

Description of drawings

Fig. 1 is the structural drawing of a kind of computer motherboard interface switching device of providing of the utility model embodiment;

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

The utility model is by expanding to 16 SATA interfaces with 4 SATA interfaces on the mainboard, and need not to use expansion card and do not take the PCI-E interface, thereby effectively utilized space size in the mainframe box, and made that the mainframe box interior layout is attractive in appearance and reached the purpose of good heat dissipation.

Fig. 1 shows the structure of computer motherboard interface switching device provided by the utility model, described device comprises industry MINI SAS (Serial Attached SCSI, Serial Attached SCSI (SAS)) interface module 1, SAS extended chip module and SATA output interface module 2.

Industry MINI SAS interface module 1 links to each other with four SATA interfaces on the computer motherboard respectively by data line, handles by SAS extended chip module then, is connected to SATA output interface module 2.

As an embodiment of the present utility model, MINI SAS interface is 4 SATA interfaces, and it is combined into a kind of interface standard of an interface in order to reduce volume, and this consensus standard is SFF-8087.Data are sent on the MINI SAS interface from the SATA interface on the mainboard, by the data line line data are sent to the SAS extended chip, and this chip maximum can be supported 16 port extension.

As an embodiment of the present utility model, described each SATA interface transmits the data-signal of coming in to be passed through after processing, the conversion, can export 4 groups of SATA data-signals, promptly 4 groups of SATA data-signals can expand to 16 groups of outputting data signals after handling, changing.

In the utility model, this device also has the twin wire of support serial (Inter-Integrated Circuit, 12C) bus interface and 4-SINGS general serial input/output bus (Serial General PurposeInput/Output, function SGPIO).Described SGPIO function is mainly used in host bus adaptor, and (HostBus Adapter is HBA) and between this mainboard interface conversion equipment.Among 4 data-signals, 3 are driven by HBA, and one is driven by this mainboard interface conversion equipment.This function can be monitored the duty of hard disk, and (this functional module is realized by a SGPIO control chip for Light Emitting Diode, LED) the luminous duty of representing that hard disk is different of lamp by for example light emitting diode.Described SGPIO control chip reads by the voltage to a signal PIN on the hard disk, and the exchanges data of SAS extended chip, judge the duty of hard disk, as activity, lost efficacy location, situations such as reconstruction, give the LED lamp different signals according to described different situation, thereby can understand the working condition of hard disk by this different signal.

The utility model connects 4 SATA interfaces on the mainboard and expands to 16 SATA interfaces by the SAS extended chip by industry MINI SAS interface, and need not to use expansion card and do not take the PCI-E interface, make the user to connect more hard disk by the SATA interface of this process expansion, thereby effectively utilized space size in the mainframe box, and made that the mainframe box interior layout is attractive in appearance and reached the good purpose of thermal diffusivity.
