Abstract
The controller of disc array system is composed of kernel logic unit, disc control unit and bus control unit. The lerkel logic unit is used to process the data from central processing unit and memory. The disc control unit is connected to the kernel logic unit electrically and communicates to disc by using IDE bus or SCSI bus. The bus control unit is connected to the kernel logic unit electrically and communicates to PCI bus with specific transport protocol. Since the drive program built in job system drives the controller of disc array system, so special drive program is not needed.
Description
The present invention relates to a kind of Magnetic Disk Controller, particularly relate to a kind of magnetic disk array system controller (redundant arrays of inexpensive disks controller, RAID controller) that need not specific drivers.
At present, in general computer system, the design of bus (bus) exactly for help central processing unit (CPU) to link and each peripheral device and storer between communication.And present the most frequently used bus mainly is peripheral element extension interface (peripheral component interconnect; PCI) bus.And on the communication interface of information between peripheral device and CPU, the overwhelming majority all is to adopt integrated form to drive electronics (integrated drive electronics; IDE) interface makes CPU and transmits information mutually as peripheral devices such as hard disks, and small part is to adopt small computer system interface (small computersystems interface; SCSI) make CPU and transmit information mutually as peripheral devices such as hard disks.
For Magnetic Disk Controller, especially for magnetic disk array system controller, it can be inserted in motherboard or pci bus etc. and communicate with one another with CPU above the regional bus, and controls the data transmission of hard disk by ide interface or scsi interface.With present magnetic disk array system controller, more common kind is the PCI-IDE/PCI-SCSI magnetic disk array system controller, and it directly inserts in the pci bus, and controls hard disk by the IDE/SCSI interface.
Yet opinion does not have standard set driver or design specification to be suggested so far as yet with existing P CI-IDE magnetic disk array system controller.Therefore, the magnetic disk array system controller that each tame manufacturer produced all must cooperate the driver of a special use to drive under different working software.What therefore, the employed driver of magnetic disk array system controller will be along with manufacturer and working software is different and different.
The object of the present invention is to provide a kind of magnetic disk array system controller structure and communication modes of novelty, it does not need additionally to install specific drivers, but drive with the PCI-IDE controller driver that includes in the operating system, to overcome the above-mentioned shortcoming of existing magnetic disk array system controller.
Above-mentioned purpose of the present invention is achieved in that a magnetic disk array system controller, it comprises a core logic unit (core logic unit), in order to handle data from a central processing unit and a storer, one disk control module (disk control unit), be electrically connected on this core logic unit and carry out communication by one first bus and a disk, and a bus control device, be electrically connected on this core logic unit and carry out communication with one second bus with a specific transfer protocol (communication protocol).Wherein this magnetic disk array system controller is exactly to drive by this second bus with an interior particular driver that is built in an operating system.
Wherein, first bus is that an integrated form drives electronics (IDE) bus or a small computer system interface (SCSI) bus, and second bus is to be a peripheral element extension interface (PCI) bus.Moreover above-mentioned bus control device can be a master control peripheral element extension interface bus controller (master PCI buscontroller) or an attached peripheral element extension interface bus controller (slave PCI buscontroller).
And the information of this specific transfer protocol is to be that a peripheral element extension interface standard code (PCI classcode), its length are 24 binary digits.And by on the configuration space working storage (configuration space register) of the information (as 010180H) of tool one particular value being inserted pci bus, then can make magnetic disk array system controller be regarded as one peripheral element extension interface-integrated form and drive electronic controller (PCI-IDE controller), drive magnetic disk array system controller and drive electronic controller driver (PCI-IDE controller driver) with the interior peripheral element extension interface-integrated form that is built in operating system.
Below in conjunction with accompanying drawing shown in the embodiment the present invention is described in further detail.
Fig. 1 is the system block diagram of magnetic disk array system controller of the present invention;
Fig. 2 is the form synoptic diagram of PCI standard code of the present invention.
With reference to Fig. 1, it has shown the system block diagrams of magnetic disk array system controller of the present invention.Magnetic disk array system controller of the present invention comprises a core logic unit 11, in order to handle from the data of central processing unit 15 with storer 16, one disk control module 12, be electrically connected on core logic unit 11, (it can be an IDE bus or a SCSI bus and by one first bus 17, and be an IDE bus in the present embodiment) carry out communication with disk 18, one bus control device (it can be a master control/attached pci bus controller) 13, be electrically connected on core logic unit 11, and carry out communication with a specific transfer protocol (being a Standard PC I communications protocol in the present embodiment) with one second bus (being a pci bus in the present embodiment) 14.
And the information of above-mentioned Standard PC I communications protocol is to be a PCI standard code, and its form then is shown in Fig. 2.The information of Standard PC I standard code has 24 binary digits (bit) as seen from Figure 2, and being divided into is three intervals.The the 0th to 7 binary digit is programmatic interface (programming interface) interval, the the 8th to 15 binary digit is secondary standard sign indicating number (sub class code) interval, and the 16th to 23 binary digit is base standard sign indicating number (base class code) interval.In order to make magnetic disk array system controller of the present invention no longer need special-purpose driver to drive, the value that we can make the programmatic interface interval is 80H, its representative can be with IDE bus master operation (capable of IDE bus masteroperation), the value that makes secondary standard sign indicating number interval is 01H, it represents IDE controller (IDEcontroller), the value that makes the base standard sign indicating number is 01H, and it represents mass storage (mass storagedevice).Therefore, if the value of the value 010180H of PCI standard code is write configuration space working storage on the pci bus, thus, magnetic disk array system controller just no longer needs special-purpose driver, and directly drive with the built-in PCI-IDE controller driver of operating system, and what seen on the peripheral device display list on the operating system will no longer be a magnetic disk array system controller, but general PCI-IDE controller.
By above explanation as can be known, magnetic disk array system controller of the present invention is owing to adopted the information format of PCI standard code and the pci bus on the computer motherboard to carry out communication, therefore, magnetic disk array system controller will no longer need special-purpose driver to drive, and drive with general job system built-in PCI-IDE or PCI-SCSI controller driver, therefore installing and using, the driver that manufacturer developed of each magnetic disk array system controller needn't be relied on, and the built-in driver of operating system can be used.Just can eliminate magnetic disk array system controller thus to the dependence of driver and make that magnetic disk array system controller can be compatible mutually with all operating systems, visible the present invention one has the invention of height commercial value.
The present invention is described in detail by the foregoing description, and the those of ordinary skill in this professional domain can be modified arbitrarily in design of the present invention, but such variation all falls within the scope of protection of the present invention.
