Abstract
The utility model provides the high speed Expander card of a kind of costdown of realization, belongs to expansion card field, and its structure has adopted LSI2X20SAS6GExpander chip, and this chip maximum can be supported 20 Phy.This chip is directly connected to hard disk backboard by disk state signal by cable, and the function that this Expander card is mainly realized is: support 12 hard disks by expansion, can realize the LED lamp instruction of disk state locate and error.
Description
Technical field
The utility model relates to expansion card field, specifically a kind of high speed Expander card of realizing costdown.
Background technology
The implementation of disk state management is mostly to complete by Expander chip, its process need has the CPLD chip that LED/GPIO is converted to SGPIO signal, by this CPLD chip, SGPIO signal is sent to respectively to backboard again, this design is comparatively complicated, process is loaded down with trivial details, easily goes wrong, and in product, PBSRAM chip is also installed in signal conversion process, make overall expansion card and interconnected back board structure compact not, and such use cost is also higher.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, and the high speed Expander card of a kind of costdown of realization is provided, and has simplified design, has reduced cost.
The utility model solves the technical scheme that its technical matters adopts:
This design has adopted LSI2X20 SAS6G Expander chip, and this chip maximum can be supported 20 Phy.The function that this Expander card is mainly realized is: support 12 hard disks by expansion, can realize the LED lamp instruction of disk state locate and error.Implementation is as follows:
(1) Expander chip 2X20 supports 20 PHY altogether, up Phy0～3, and totally 8 phy in phy4～7 are connected to 2 MiniSAS interfaces by PCB cabling, connect the SAS/RAID card of up-link by cable;
(2) descending phy8～11, phy12～15, phy16～phy19 is 12phy altogether, is connected to successively 3 MiniSAS interfaces by PCB cabling, is connected to descending 12 mouthfuls of backboards supports 12 hard disks by cable;
(3) Expander supports the output of the Active/Locate/Error state of hard disk, corresponding 3 LED states of each phy, take wherein locate and the error signal of design requirement, be connected to descending 12 mouthfuls of backboards by cable, distribute to the LED of corresponding hard disk, the LED that realizes disk state shows;
(4) all the other modules: supply module, the power supply interconnected with Expander provides 12V input, by the 3.3V of VR conversion chip output Expander demand, 1.8V, 1.0V;
(5) all the other modules: Flash module, Flash chip is connected with Expander by parallel DDR bus, realizes storage and the startup of Expander Firmware.
Compared with prior art, the beneficial effect producing is the utility model:
This expansion card only needs to realize the development requires of one-level expanded function and disk state management based on product, and the feature of expansion card and interconnected back board structure compactness in environment for use, improves in following two schemes, greatly reduces cost:
(1) improve in the implementation of disk state management, directly disk state signal (Active/locate/error) is connected to hard disk backboard by cable, and deducted the CPLD chip that LED/GPIO is converted to SGPIO signal, and simplify design, reduce cost.
(2) apply without large topologys such as JBOD cascades based on product, delete PBSRAM chip.
Meanwhile, this expansion card is supported other functions of similar board, supports 6Gbps high speed data transfer, supports SATA/SAS/SSD polytype hard disk, can realize the expanded application of 12 hard disks, supports tri-kinds of condition managings of hard disk Active/locate/error.
