Abstract
The utility model discloses a novel SAS hard disk backplate structure belongs to the hard disk backplate, the utility model discloses the technical problem who solves is how can shortening the cost that SAS walked the line overlength and saved the CPLD chip. Technical scheme does: its structure includes hard disk backplate, CPU, PCH, HBA and connector, its characterized in that: be provided with the main chip exp of hard disk extension on the hard disk backplate, the main chip exp of hard disk extension passes through the pin with the hard disk backplate and is connected, CPU passes through the pin with HBA and PCH respectively and is connected, and HBA passes through the pin with the setting at two connectors on one side of the hard disk backplate respectively and is connected, and two connectors all are connected through pin and hard disk backplate, and the main chip exp of hard disk extension is connected to the SAS interface through the connector.
Description
Technical field
This utility model relates to a kind of hard disk backboard, a kind of novel SAS hard disk backboard structure.
Background technology
In server field, extension master chip expander is placed on mainboard by the most traditional hard disk expansion scheme, as shown in Figure 1, expander through the adapter of mainboard and backboard to SAS interface, signal lead is long, ensureing signal integrity in being to increase Redriver chip, cause structure complicated, line is the most intricate.Traditional structure realizes based on CPLD the management of SAS interface led, uses CPLD by the parsing to SGPIO signal, the action of output hard disk LED status, indicated by the state of SGPIO consultative management hard disk lamp, cause relatively costly, take up room bigger simultaneously；How can shorten long and saving CPLD chip the cost of SAS cabling is the technical problem that presently, there are.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of novel SAS hard disk backboard structure, solves how can to shorten SAS cabling long and save the problem of cost of CPLD chip.
This utility model solves its technical problem and be the technical scheme is that a kind of novel SAS hard disk backboard structure, including hard disk backboard, CPU, PCH, HBA and adapter, it is provided with hard disk extension master chip Exp, hard disk extension master chip Exp on described hard disk backboard to be connected by pin with hard disk backboard；CPU is connected by pin with HBA and PCH respectively, and HBA is connected by pin with two adapters being arranged on hard disk backboard side respectively, and two adapters are all connected with hard disk backboard by pin, and hard disk extension master chip Exp is connected to SAS interface by adapter.
As preferably, described hard disk extension master chip Exp comprises GPIO management agreement.
As preferably, described SAS interface is provided with LED.
Other connected modes with structure all in of the prior art consistent.
One of the present utility model novel SAS hard disk backboard structure is compared to the prior art, have the advantages that on this utility model, hard disk extension master chip is placed on backboard, from the most traditional hard disk expansion scheme, hard disk is extended master chip Exp and be placed on mainboard different, save motherboard space and substantially reduce the track lengths of hard disk, thus save redriver chip cost, and meet the high speed signal code requirement of SAS3.012G.Simultaneously, the most traditional structure is based on CPLD, indicated by the state of SGPIO consultative management hard disk lamp, i.e. use hard disk extension self GPIO of master chip Exp to realize the management of SASLED lamp by the secondary development of hard disk extension master chip Exp firmware, thus the cost saving CPLD chip has saved space simultaneously.
This utility model has reasonable in design, simple in construction, the features such as processing, little, easy to use, the one-object-many-purposes of volume that are prone to, thus, have good value for applications.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further illustrated.
Accompanying drawing 1 is the block diagram of SAS hard disk backboard structure traditional in background technology；
Accompanying drawing 2 is the block diagram of a kind of novel SAS hard disk backboard structure.
Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
One of the present utility model novel SAS hard disk backboard structure, its structure includes hard disk backboard, CPU, PCH, HBA and adapter, hard disk backboard is provided with hard disk extension master chip Exp, hard disk extension master chip Exp and is connected by pin with hard disk backboard；CPU is connected by pin with HBA and PCH respectively, and HBA is connected by pin with two adapters being arranged on hard disk backboard side respectively, and two adapters are all connected with hard disk backboard by pin, and hard disk extension master chip Exp is connected to SAS interface by adapter.Hard disk extension master chip Exp comprises GPIO management agreement.It is provided with LED on SAS interface.
By detailed description of the invention above, described those skilled in the art can readily realize this utility model.It is understood that this utility model is not limited to above-mentioned detailed description of the invention.On the basis of disclosed embodiment, described those skilled in the art can the different technical characteristic of combination in any, thus realize different technical schemes.
