Embodiment

The utility model has multiple implementation, is that the utility model is elaborated for example with the hard-disk interface for the SATA hard-disk interface below:

Fig. 1 is the structure principle chart of memory function card, as shown in the figure, a kind of memory function card described in the utility model (100) comprising: PCIE 1X interface (101), RAID control module (102) that is connected with PCIE 1X interface (101) and power supply unit (103), the SATA hard disk control module (105) that is connected with power supply unit (103), at least two the SATA hard-disk interfaces (106) that are connected with SATA hard disk control module (105), the SSD control module (107) that is connected with power supply unit (103), SATA DEVICE interface (110) that is connected with SSD control module (107) and flash chip (109).

PCIE 1X interface 101 connects mainboard, is used to realize the transmitted in both directions of information between mainboard and the RAID control module (102).For example receive the data of mainboard transmission and instruction or, can transmit data with binary mode, and the electric current on the mainboard is introduced the memory function card to mainboard transmission data by PCIE 1X interface.

Data that RAID control module (102) and SATA hard disk control module (105) receive from PCIE 1X interface (101) and instruction by the hard disk that is connected to SATA hard-disk interface 106 is distinguished accordingly, reading and writing and other operations.

Power supply unit (103) obtains power supply and is converted to RAID control module (102), SATA hard disk control module (105) and SSD control module (107) required voltage and controls the size of electric current separately from PCIE 1X interface 101.

SSD control module (107) is used for that data, instruction and sequential that flash chip (109) sends are converted to SATA DEVICE interface (110) can recognition data, instruction and sequential.

SATA DEVICE interface (110) connects mainboard, is used for data, instruction and sequential after SSD control module (107) conversion are transferred to mainboard, and receives data and instruction from mainboard.

The principle of work of memory function card of the present utility model (100) is as follows in practical operation:

Connect ten SATA hard disks respectively on the SATA hard-disk interface (106) of memory function card (100), memory function card (100) is connected with the PCIE 1X slot of mainboard by its PCIE 1X interface (101), and be connected with the SATA interface of mainboard by its SATA DEVICE interface (110), so far memory function card (100) installed.

The user is provided with the computing machine acquiescence and starts from the system disk that is connected with mainboard, after computing machine powers on, because SATA DEVICE interface (110) is connected with the SATA interface of mainboard, so computer system is the os starting from the flash chip (109) preferentially, also can be set to start from SATA DEVICE interface (110).

Power supply unit (103) gets electric back by PCIE 1X interface (101) from mainboard and is SSD control module (107) power supply, SSD control module (107) electric after, the flash chip (109) that is connected is configured to the SATA standard hard disk that to be discerned by mainboard, computer system preferentially reads flash chip (109) by SSD control module (107), and the operating system in the flash chip (109) is written into internal memory, be written into the driver of storage management software and RAID control module (102), other inputoutput units and various peripheral hardwares simultaneously.

When storage management software receive the RAID system carried out reading and writing or other instruction after, the storage management software instruction by driver to PCIE 1X interface (101) corresponding binary data of output and level.When the input write command, because current RAID control module (102) has been configured to RAID0, RAID control module (102) and SATA hard disk control module (105) are separated into ten parts according to the RAID0 pattern with raw data and respectively ten hard disks are write.After the input sense command, RAID control module (102) and SATA hard disk control module (105) are according to the above-mentioned standard that writes the address, simultaneously from ten hard disk sense datas.

With reference to the foregoing description, if computer system is connected with N piece hard disk (N 〉=2), so behind computer starting, RAID control module (102) will detect N piece SATA hard disk, when execution writes instruction, RAID control module (102) and SATA hard disk control module (105) will be divided into raw data N part and write the SATA hard disk respectively.When carrying out sense command, according to writing the address standard, simultaneously from N piece SATA hard disk sense data.

Accordingly, if it is mode of operation that the user is provided with RAID1, so when carrying out write operation, RAID control module (102) and SATA hard disk control module (105) write same data to the hard disk that is connected to SATA hard-disk interface (106) simultaneously, when carrying out read operation, read from SATA hard disk wherein.

In the above-described embodiments, if the initial configuration of RAID-BIOS dispensing unit is other patterns of RAID, then write/during read operation, will carry out according to each pattern regulation of RAID in execution.

The above embodiments are to be that example describes with flash chip (109) or the SATA DEVICE interface (110) that is connected to mainboard as system disk, therefore, because equipment supplier or manufacturer have debugged driver special purpose operating system and storage management software and be stored in the memory function card, therefore do not need user installation operating system, driving, storage management software or debug.In addition, because had the system disk that other are connected with SATA DEVICE interface (110) in the computer system, then the utility model also can be used as common RAID adapter use, method be with already present system disk as boot disk, the driver that is written into operating system wherein and the utility model correspondence is installed in operating system just can be carried out the writing of RAID system, read operation by foregoing description.

On the memory function card of the present utility model the LED lamp can also be set, be used for showing the duty of hard disk, when RAID control module (102) and SATA hard disk control module (105) carried out read-write operation to hard disk, the LED lamp was luminous; When the RAID control module stopped that hard disk carried out read-write operation, the LED lamp extinguished, and is convenient to the working condition that the user intuitively observes hard disk.In addition, do not connect the SATA hard disk as SATA hard-disk interface of the present utility model (106), then the utlity model has the function of SATA adapter, flash chip (109) can be used as solid state hard disc and uses.Flash chip also can be placed the dedicated system that other customizes in (109), does not need to provide the installation medium to be installed by the final user.

The above embodiment is the part among the many embodiment of the utility model, and simple modification that those skilled in the art are carried out on this basis or the simple replacement that some parts is done all should be included within the protection domain of the present utility model.
