Specific embodiment

The utility model is specifically described below in conjunction with the accompanying drawings, it is as Figure 1-3, a kind of based on CPCIE frameworks Storage expansion card, including mainboard（1）And control chip（2）, the control chip（2）By one group of signaling module A（3）With mainboard （1）It is connected, the mainboard（1）On by one group of signaling module A（3）External expansible 16 SAS interfaces（4）, the mainboard（1）It is logical Cross one group of signaling module B（5）It is connected with network chip（6）;The mainboard（1）Framework is 3U CPC frameworks I;The control chip （2）Model Marvell 88SE1495 SAS;One group of signaling module A（3）Model PCIEx8;The network core Piece（6）Model intel 82574;One group of signaling module B（5）It is PCIEx1.

The characteristics of the present embodiment is that control chip is connected by one group of signaling module A with mainboard, by one group of letter on mainboard The external expansible 16 SAS interfaces of number modules A, mainboard is connected with network chip, master controller use by one group of signaling module B Marvell 88SE1495 SAS control chips, at the same integrated gigabit all the way management network, most expansible 16 pieces of SAS hard disks, Flank speed supports 12Gbps, while supporting that 6Gbps, 3Gbps and 1.5Gbps, board not only realize band based on CPCIE frameworks Width is broken through, and high reliability and modular feature has been also equipped with, while enhancing the reinforcement performance of board.

In the present embodiment, two-way PCIE signal is realized transmitting by XJ1, wherein PCIEx1 signals are connected to all the way The chips of intel 82574, so as to extend gigabit management network interface all the way, for the communication in storage system and the external world, in addition one Road PCIEx8 signals are connected to Marvell 88SE1495 SAS control chips, such that it is able to extend 16 road SAS hard-disk interfaces, its The middle RJ45 and SAS signals drawn by 82574 and 88SE1495 chips respectively are realized transmitting by XJ2, in power supply mode, J3 Three road voltages needed for providing board, are respectively 12V, 5V and 3.3V, and 12V is passed through respectively as the electricity required for supply fan, 5V The 2.5V that crosses required for LTC3878 and MAX1945 electrical level transferring chips are converted to Marvell 88SE1496 SAS control chips, 1.8V and the road voltages of 0.9V tri-, the 1.9V required for a 3.3V parts are converted to Intel 82574 by RT9018B are electric, in addition A part is directly used as the voltage of LED light.The electric current of wherein each road electricity output can guarantee that the normal work of chip, protect Demonstrate,proved the stable operation of board, the internal structure of SAS controller, comprising 16 ports, the SAS interfaces of compatible 12Gbps and The SATA interface of 6Gbps, comprising an interface of the PCIe of 8 passages 3.0.Both supported that Serial Attached SCSI 3.0 were assisted View, supports the protocol specifications of Serial ATA 3.0 again, while being used for the communication with internal control chip there is provided 5 road I2C serial ports And two serial ports of professional standard 57600, power consumption as little as 9.5W, the diffusion of heat can be realized by fin, by above-mentioned side Case realizes a kind of design of the storage expansion card based on CPCIE frameworks, and the storage expansion card designed by patent of the present invention is in property Can go up and also be improved significantly, first, in volume, using the SAS controller of small size, its size is only 21 × Secondly 21mm, board, in interface quantity, could support up 16 SAS interfaces using the 3U structures of standard, store maximum capacity Up to 16T, memory capacity is significantly lifted, and functionally, the integrated gigabit ethernet networks of Intel all the way 892574 are enriched The function of expansion card, can realize the management function of storage software by this network interface when using, finally, in compatibility, can The SAS3.0 signals of compatible 12Gbps and the SATA3.0 signals of 6Gbps, user can be configured according to the demand of oneself.
