Abstract
The utility model provides a server main board capable of supporting intelligent switching of a serial attached small computer system interface (SAS) and a serial advanced technology attachment (SATA). The server main board capable of supporting intelligent switching of the SAS and the SATA structurally comprises a printed circuit, wherein the printed circuit board is provided with an SAS/SATA switch, a complex programmable logic device (CPLD) and a serial general purpose input/output (SGPIO) switch, the CPLD is connected with the SAS/SATA switch, the SGPIO switch is connected with the CPLD, and an SATA controller and an SAS card are further arranged between the SAS/SATA switch and the SGPIO switch. Compared with the prior art, the server main board capable of supporting intelligent switching of the SAS and the SATA has the advantages of reasonable design, simple structure and convenient use and the like, saves external expansion image orthicon, improves flexibility and usability of blades, meets requirements of different users, and can be widely applied for high-end blade server nodes.
Description
Technical field
The utility model relates to the computer communication technology field, specifically a kind of simple in structure, can support the server master board that SAS and SATA intelligence is switched.
Background technology
Along with the development of technology, the density of various blade servers increases gradually, and can also grow with each passing day for the demand of peripheral IO and since the intrinsic feature limits of blade server the quantity of external expansion IO, it is particularly important that this just makes that plate carries IO.Plate carries the restriction that IO is subjected to the characteristics of blade server equally, carries out the intelligence switching thereby just need carry IO to plate, realizes the demand of its multiple function, improves the quantity of the expansion IO of blade server.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of simple in structure, the server master board that can support SAS and the switching of SATA intelligence is provided.
The technical solution of the utility model realizes in the following manner, this a kind of server master board of supporting that SAS and SATA intelligence are switched, its structure comprises printed circuit board (PCB), described printed circuit board (PCB) is provided with SAS/SATA switch, the CPLD that is connected with this SAS/SATA switch, the SGPIO switch that is connected with CPLD, also is provided with SATA controller and SAS card between above-mentioned SAS/SATA switch and the SGPIO switch.
In technique scheme, the SATA controller is used for SATA is provided interface; The SAS card is used for SAS is provided interface, and SAS/SATA Switch module realizes the switching of sas and sata signal; SGPIO Switch module realizes the switching of SAS and SATA SGPIO, and the switch here refers to switch; CPLD realizes the parsing of SAS or SATA SGPIO signal, the action of output HDD LED status.
As preferably, described printed circuit board (PCB) also is connected with some hard disk drives by the BP interface, and that wherein be connected with the BP interface is SAS/SATA switch and CPLD on the printed circuit board (PCB).
In sum, the beneficial effect that compared with prior art produces of the utility model is:
The server master board that a kind of SAS of support of the present utility model and SATA intelligence are switched has characteristics such as simple in structure, easy to use, novel, saved outside expansion IO, and dirigibility and the ease for use of blade configuration have been improved, meet the needs of different users, can be widely used in high-end blade server node, convenient easy-to-use, effectively promote reliability of products and competitive power.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.

Embodiment
Below in conjunction with accompanying drawing a kind of server master board of supporting that SAS and SATA intelligence are switched of the present utility model is done following detailed description the in detail.
As shown in Figure 1, this a kind of server master board of supporting that SAS and SATA intelligence are switched, its structure comprises printed circuit board (PCB) 1, described printed circuit board (PCB) 1 is provided with SAS/SATA switch3, the CPLD6 that is connected with this SAS/SATA switch3, the SGPIO switch7 that is connected with CPLD6, also is provided with SATA controller 2 and SAS card 8 between above-mentioned SAS/SATA switch3 and the SGPIO switch7.
Described printed circuit board (PCB) 1 also is connected with some hard disk drives 5 by BP interface 4, and that wherein be connected with BP interface 4 is SAS/SATA switch3 and CPLD6 on the printed circuit board (PCB) 1.
Signal by SAS/SATA_SEL between above-mentioned SAS/SATA switch3, CPLD6 and the SGPIO switch7 is realized communication, and the control mode of the signal of this SAS/SATA_SEL comprises:
A) according to hardware configuration, namely utilize the signal in place (PNT#) of SAS card to realize, be that the SAS signal gating is effective when namely plugging SAS card 8, and SATA signal gating in place is effective when not inserting SAS card 8.
B) dispose according to jumping cap, when namely SAS card 8 was in place, the user selected SATA for use, then only need pull up to jump cap and can realize the sata gating, plugged to jump cap and then realize the SAS gating.
C) control command by BMC realizes.Be that the user can control gating signal and realizes online switching to SAS and SATA under the situation that does not plug blade.
Except the described technical characterictic of instructions, be the known technology of those skilled in the art.
