Description
Technical field
The present invention is about a kind of expansion type SATA interface base plate, it is about being used in the base plate of SATA interface control unit, be meant that especially a kind of SATA interface base plate can expand the demand of storage device hard drives according to the user, and serial connection expands raising use elasticity.
Background technology
The function that computing machine had now can be said so very powerful, and it not only can help the common people to handle considerable affairs, also can provide common people's amusement and recreation, so for present each common people, computing machine is can not obtain scarce equipment in the life.Under scientific and technological fast development, the calculation process speed of the CPU (central processing unit) of computing machine is quite fast now, and storage device hard drives (Hard diskdrive, HDD) storage volume is also quite big, so, the usefulness of computing machine integral body can be subjected to the influence of hard drives transmission speed, especially similarly is the computer server that needs a plurality of hard drives of installing.So the interface of hard drives transmission now is gradually from run-in index ATA (ParallelAdvanced Technology Attachment), be ide interface (Integrated DeviceElectronic Interface), change transmission speed list type (Serial) ata interface faster into, abbreviate SAT A interface is to improve the overall efficiency of computing machine.
When computer server uses the plural hard drives of SATA interface transmission in installing, must install a SATA interface control unit additional, the SATA interface control unit has plurality of specifications such as 4/6/8/12 port now, the user expands the quantity of hard drives according to desire and chooses, and should the installing of plural number hard drives be fixed in the pickup groove of an extraction box, extract on the box and be equiped with a base plate (Backplane) identical with SATA interface control unit specification, base plate is provided with the slot that disseminates and establish for each hard drives, each slot relatively respectively is connected to a SATA interface input/output end port, each SATA interface input/output end port of base plate is again by using transmission line to be connected with the SATA interface I/O end of SATA interface control unit, the base plate significant feature has RAID (Redundant Array OfIndependent Disk Drives) function to do the management of disk array (Disk Array), to improve the security of the data of being deposited in the hard drives, and base plate can have hot plug (Hot-Swap) function by hard drives, allow the user when desire is changed hard drives, needn't turn off computing machine earlier can carry out, and can make the state detecting of hard drives.
So, the use specification of base plate must be arranged in pairs or groups and is same as the SATA interface control unit, the base plate that is to say one 4 slots only can be supported the SATA interface control unit of one 4 I/O ends, push away it equally, the base plate of 6 slots is joined the SATA interface control unit of 6 input/output end ports, so use down when the user all is connected with hard drives in the connectivity port that the SATA interface control unit of installing and using is at present supplied, when desiring to expand hard drives again, must change higher SATA interface control unit and the base plate of terminal number is installed, so go up quite inconvenience of system in expanding to use, expand the cost height, and cause old device resource waste.
Therefore, how the present invention promptly proposes a kind of expansion type SATA interface base plate at the problems referred to above, make base plate can expand the needs of hard drives according to the user, and serial connection expands combination, so be not easy to use the person and expand, do not need again the other base plate that more renews, to improve the use elasticity of base plate, can support to cooperate the SATA interface control unit of all size, to address the above problem.
Summary of the invention
Fundamental purpose of the present invention, be to provide a kind of expansion type list type to advance the interface base plate of rank technology attachment specifications (abbreviate SAT A), can expand the needs of hard drives according to the user, and serial connection combination S ata interface base plate, SATA interface control unit with the collocation all size, and the use elasticity of raising base plate reduces the cost that the user expands.
Another object of the present invention is to provide a kind of expansion type SATA interface base plate, and the control device of its SATA interface base plate can be known the state that base plate uses for the substrate management and control device monitoring of computing machine, manages to make things convenient for computer management system.
Expansion type SATA interface base plate of the present invention, it can expand the plural SATA interface base plate serial connection combination that plugs for plural hard drives, use a SATA interface control unit that is installed in a computer server with collocation, each SATA interface base plate is provided with plural SATA interface input/output end port, one control device, one first I/O end and one second I/O end, the first I/O end of SATA interface control unit and one the one SATA interface base plate is electrically connected, and the second I/O end of a SATA interface base plate is connected in series mutually with the first I/O end of another SATA interface base plate, push away it according to this, the second I/O end of another SATA interface base plate is connected in series mutually with the first I/O end of next SATA interface base plate, the second I/O end of one this SATA interface base plate of serial connection expansion at last is electrically connected with a substrate management and control device that is installed on this computer server, to monitor the state of each this SATA interface base plate, so the user can expand the quantity of hard drives according to desire, use the combination of plural SATA interface base plate serial connection to expand, and do not need to buy again the SATA interface base plate that can support than multiport, to change original SATA interface base plate, so can increase the use elasticity of SATA interface base plate.
