Description
Technical field
The present invention relates to a kind of extendible backboards of SAS, the extendible backboards of SAS of more particularly to a kind of changeable framework.
Background technology
SAS (Serial Attached SCSI) is that Serial Attached SCSI (SAS) expands framework mainly including Standalone frameworks
With two kinds of frameworks of Daisy-Chain frameworks.In the backboard of Standalone frameworks, each expansion board（SAS Expander）Point
Connected, and be not connected between expansion board by Mini-SASCable connections not between corresponding promoter.And Daisy-
Interconnected between the backboard of Chain frameworks, expansion board by Mini-SAS Cable connections.
When designing the extendible backboards of SAS, traditional way is according to the different backboard of different architecture designs, so if needing
Two kinds of frameworks are supported simultaneously, then need to design two pieces of backboards, be inconvenient.
The content of the invention
In view of this, it is necessary to which a kind of extendible backboards of SAS of changeable framework are provided.
A kind of extendible backboards of SAS, including one be used to connecting the baseboard controller BMC of some hard disks, one can for expansion
First expansion board of the hard disk quantity of connection and one second expansion board.The extendible backboards of the SAS also include：One multiplexer, with
BMC, the first expansion board and the connection of the second expansion board, expand for switching to the first expansion board according to a GPIO signals with second
Plate disconnects, or switches to and be connected with the second expansion board.
The extendible backboards of SAS of the present invention are automatically switched to according to Mini-SAS Cable connection method differences
Standalone framework or Daisy-Chain framework, provide the user conveniently.

Following embodiment will further illustrate the present invention with reference to above-mentioned accompanying drawing.
Embodiment
Referring to Fig. 1, the structural representation of the extendible backboards of SAS for the changeable framework under preferred embodiments of the present invention
Figure.The extendible backboards of SAS may include multiple expansion boards, for ease of understanding, be illustrated below exemplified by two.
The extendible backboards 10 of SAS include an expansion board a101, a multiplexer 200, a BMC300 and an expansion board b201.
BMC300 is used to connect some hard disks (such as SAS/SATA Drive).Expansion board a101 and expansion board b201 is used to expand and can connect
Hard disk quantity.
Multiplexer 200 is connected with expansion board a101, BMC300 and expansion board b201.Wherein, multiplexer 200 also has
One GPIO port, for obtaining a GPIO signals, so as to control multiplexer 200.Multiplexer 200 is used for according to GPIO signals
Expansion board a101 switchings is disconnected with expansion board b201, or switch to and be connected with expansion board b201.
GPIO signals are different according to Mini-SASCable connection method difference.Specifically, using Standalone
During framework, there is no Mini-SAS Cable connections between expansion board a101 and expansion board b201, GPIO signals are 1；Using
During Daisy-Chain frameworks, connected between expansion board a101 and expansion board b201 by Mini-SASCable, GPIO signals are
0。
Referring to Fig. 2, the schematic diagram of the framework for switching to Standalone for the extendible backboards of SAS in Fig. 1.
Under Standalone pattern, GPIO signals are 1, and multiplexer 200 makes expansion board a101 be connected by Mini-SAS Cable
One promoter a102, makes expansion board b201 pass through Mini-SAS Cable connections one promoter b202, expansion board a101 and expansion
Plate b201 is connected to BMC300.
Referring to Fig. 3, the schematic diagram of the framework for switching to Daisy-Chain for the extendible backboards of SAS in Fig. 1.
In Daisy-Chain pattern, connected between expansion board a101 and expansion board b201 by Mini-SAS Cable, GPIO signals
For 0, multiplexer 200 makes expansion board a101 by Mini-SAS Cable Connection initiator a102, passes through expansion board a101
Mini-SAS Cable are connected with expansion board b201, and expansion board b201 is connected to BMC300 by expansion board a101.
The extendible backboards 10 of SAS of the present invention are automatically switched to according to Mini-SAS Cable connection method differences
Standalone framework or Daisy-Chain framework, provide the user conveniently.
In a word, those skilled in the art are it should be appreciated that the embodiment of the above is intended merely to explanation originally
Invention, and be not used as limitation of the invention, as long as within the spirit of the present invention, to above example institute
The appropriate change and change made all fall within the scope of protection of present invention.
