Description

A kind of multi-host interface memory controller

1, technical field

The utility model relates to a kind of computer memory technical field, specifically a kind of multi-host interface memory controller.

2, background technology

Infotech is just from being that to enter into the memory device in calculating epoch of core be the storage epoch of core with the computing equipment, the networking storage will become the focus of following storage market, and the network storage has become the third wave after computing machine tide and internet tide.Domestic and international high-end storage products is generally supported the FC optical fiber interface at present, mid and low-end products are supported gigabit Ethernet network interface, and that user's network storage environment thousand differs from is ten thousand different, many main frames high-speed communication interface to storage products has high requirement, so do not expand and dumbly can not satisfy different application environment and network environment but present product does not have multi-host interface, can't realize the fault-tolerant of main-machine communication network.

3, summary of the invention

For solving above deficiency, a kind of multi-host interface memory controller purpose of the present utility model provides the memory controller of little, the intelligent degree height of a kind of volume, integrated multiple host interface, integrated CPU, north bridge, south bridge, SAS controller 1, SAS controller 2, kilomega network controller 1, kilomega network controller 2, FC controller and VGA interface, SDRAM, BIOS, ide interface DOM dish, PCI socket, USB interface, SAS interface, gigabit networking interface, FC optical fiber interface on a circuit.Wherein the CPU module is connected by the FSB bus with the north bridge module, north bridge is connected by the DMI bus with south bridge, north bridge is connected with SAS controller 1, FC optical fiber controller respectively by the PCI-E bus, and south bridge is connected with SAS controller 1, gigabit networking controller 1, gigabit networking controller 2 respectively by the PCI-E bus.

This design makes multi-host interface memory controller of the present utility model have multi-host interface, can expand, and can satisfy different application environment and network environment flexibly, can realize the fault-tolerant function of main-machine communication network.

4, description of drawings

Accompanying drawing 1 is a kind of electrical block diagram of multi-host interface memory controller.

CPU (1), north bridge (2), south bridge (3) SAS controller 1 (5), SAS controller 2 (8), kilomega network controller 1 (6), kilomega network controller 2 (9), FC controller (7) and VGA interface (11), SDRAM (12), BIOS (13), ide interface DOM dish (14), PCI socket (15), USB interface (16), SAS main frame and JBOD interface (17), gigabit networking interface (18), FC optical fiber interface (19), SAS hard-disk interface (20).

5, embodiment

Below in conjunction with accompanying drawing multi-host interface memory controller of the present utility model is done following detailed explanation.

Integrated CPU, north bridge, south bridge, SAS controller 1, SAS controller 2, kilomega network controller 1, kilomega network controller 2, FC controller and VGA interface, SDRAM, BIOS, ide interface DOM dish, PCI socket, USB interface, SAS interface, gigabit networking interface, FC optical fiber interface on a circuit.Wherein the CPU module is connected by the FSB bus with the north bridge module, north bridge is connected by the DMI bus with south bridge, north bridge is connected with SAS controller 1, FC optical fiber controller respectively by the PCI-E bus, and south bridge is connected with SAS controller 1, gigabit networking controller 1, gigabit networking controller 2 respectively by the PCI-E bus.

After controller powers on, at first move bios program, hardware is carried out initialization, the embedded OS in the ide interface DOM dish and storage control application software are downloaded among the SDRAM moves then, storage control application software is by host interface and main-machine communication:

1) write data: the data that main frame is sent unpack the computing with RAID, write in the hard disk array by the SAS controller at last.

2) read data: read hard disc data by the SAS controller, packing sends to main frame by host interface then.

3) but the memory controller automatic or manual is provided with various host communication interface, host interface automatically switches to other host communication interface after having fault, realizes the fault-tolerant of network.

The utility model is compared with existing technology, and has little, the intelligent degree height of volume, integrated multiple master Machine interface, the various applied environments of adaptation user, main-machine communication Its Fault Tolerance high, thereby, tool Good popularizing value is arranged.

Except the described technical characterictic of specification, be the known technology of those skilled in the art.
