Description
Technical field
The present invention is relevant for a kind of expansion type SATA interface backboard, it is about being used in the backboard of SATA interface control unit, be meant that especially a kind of SATA interface backboard can expand the demand of storage device hard drives according to the user, and serial connection expands raising use elasticity.
Background technology
Press, 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 drive 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 (Parallel AdvancedTechnology Attachment), be ide interface (Integrated Device ElectronicInterface), 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 drive 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 and to be equiped with one of identical with SATA interface control unit specification backboard (Backplane) on the box, backboard 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 backboard is again by using transmission line to be connected with the SATA interface I/O end of SATA interface control unit, the backboard significant feature has RAID (Redundant Array Of Independent DiskDrives) 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 backboard 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 backboard must be arranged in pairs or groups and is same as the SATA interface control unit, the backboard 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 backboard of slot 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 backboard 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 backboard at the problems referred to above, make backboard 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 backboard that more renews, to improve the use elasticity of backboard, 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 backboard 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 backboard, SATA interface control unit with the collocation all size, and the use elasticity of raising backboard reduces the cost that the user expands.
Another object of the present invention is to provide a kind of expansion type SATA interface backboard, and the control device of its SATA interface backboard can be known the state that backboard 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 backboard of the present invention, it can expand the plural SATA interface backboard serial connection combination that plugs for plural hard drive, be installed in one of computer server SATA interface control unit with the collocation use, each SATA interface backboard is provided with plural SATA interface input/output end port, one control device, one first I/O end and one second input/output end port, the first I/O end of SATA interface control unit and one the one SATA interface backboard is electrically connected, and the second I/O end of a SATA interface backboard is connected in series mutually with the first I/O end of another SATA interface backboard, push away it according to this, the second I/O end of another SATA interface backboard is connected in series mutually with the first I/O end of next SATA interface backboard, the quantity that user like this can expand hard drive according to desire, use the combination of plural SATA interface backboard serial connection to expand, and do not need to buy again the SATA interface backboard that can support than multiport, to change original SATA interface backboard, so can increase the use elasticity of SATA interface backboard.
