The utility model discloses be convenient for dispose at standard 4U machine incasement, nimble configuration can realize the single accuse of storage by monolithic storage extension integrated circuit board, and it is available also can to realize that multipath redundancy design improves the system through two storage extension integrated circuit boards.
Description
Technical field
This utility model relates to memory expansion unit field, specifically a kind of high-end server storage expansion card.
Background technology
Big data age, cloud storage provides Large Copacity storage mode easily, the locally stored of server be it is also proposed higher requirement simultaneously, and the stability to server storage data, the extension of memory capacity is had higher requirement.
Summary of the invention
The utility model proposes a kind of high-end server storage expansion card, it is achieved redundant link design in terms of server storage extension, the very big locally stored capacity of expansion service device, by demand flexible configuration single control/dual control storage link, availability is high.
Technical solution adopted in the utility model is:
This utility model application Avago3X40SASExpander chip realizes SAS and stores expanded function, 40 SAS3.0 (12Gbps) phy of maximum support, X8SAS signal extension to the 24XSAS signal that front end HBA/RAID card sends can be connected to hard disk, retain 8 SASphy and realize storing expansion card cascade function with other 4U cabinets by outside miniSASHD interface.Separate unit 4U node maximum can be extended to 24*4TB memory capacity, and Expander chip sends and meets the SGPIO signal equiband signal of SFF8485 specification and be connected to CPLD and manage hard disk indication lamp function.
This storage expansion card is individually powered, and coordinates storage expansion board clamping, it is possible to achieve single path stores, it is possible to use two pieces of identical storage expansion cards realize dual control Redundancy Design.During dual control Redundancy Design, storage expansion card uses I2C/UART bus to be interconnected by storage backboard, it is achieved heartbeat function.
Use PSOC chip to realize temperature voltage monitoring on card body, send the temperature/voltage information detected to server management module by I2C bus.
Card body uses SDBUARTheader, is mainly used in Expander chip FW burning；UARTheader, application Expander chip debuglog capture and obtain Expander chip, reserve ICEJTAG adapter simultaneously.
The beneficial effects of the utility model:
The storage expansion board clamping that the utility model proposes coordinates storage backboard, it is easy to dispose in standard 4U cabinet, flexible configuration, can realize storage single control with monolithic storage expansion board clamping, it is also possible to realizing multipath Redundancy Design raising system by two panels storage expansion board clamping can use.
Accompanying drawing explanation
Accompanying drawing 1 is storage expansion board block diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail below.
Storage expansion board clamping is integrated in standard 4U extended housing, interconnected with storage backboard by high speed connector, the SAS signal of the storage controls such as HBA/RAID card is connected to store backboard by cable, storage backboard is forwarded to Expander chip through high speed connector again, Expander chip extends to 32XSAS signal after receiving the SAS signal that front end storage control sends, wherein 24XSAS signal is used for expanding hard disk, 8XSAS signal is used for cascading, the up port of 4X is used for connecting higher level's Expander chip (if front end is that HBA/RAID card is then applied) without this, the descending port of 4X is used for cascading extension next stage extension Expander.
Using S29GL128S10TFIV2032MBNORflash chip (nonvolatile flash memory) as Expander chip FW storage medium on storage expansion board clamping, work for chip guide, efficiency of transmission is high, low cost, and ruggedness is high.MR0D08BMA45R8MBNVSRAM chip (Nonvolatile sram) is used to preserve the important debuglog information that can not lose when power down.
Storage expansion board clamping uses PSOC (ProgrammableSystem-On-Chip) chip to realize temperature voltage monitoring, use Sai Pulasi PSOC4 low cost ARM solution, 3 panel region temperature on the expansion board clamping of monitoring storage in real time, air inlet (board front end), air outlet (board rear end), Expander chip body, and synchronize to obtain all information of voltage of board, send the temperature/voltage information detected to server management module by I2C bus.
Storage expansion board uses SDBUARTheader, is mainly used in Expander chip FW burning；UARTheader, application Expander chip debuglog captures and obtains Expander chip, reserves ICEJTAG adapter (IEEE1149.1 is compatible) simultaneously, is mainly used in Expander chip internal test/Debug, multiple debug Interference fit uses, and enhances the maintainability of this board.
Two pieces of identical storage expansion board clampings are used during dual control storage application, I2C/UART bus is used to be connected to terminal adapter by high speed connector through storage backboard cabling, two expander chips can know opposite end chip operation state in time, adjusts self working.
Board mainly by board to board connector from the storage backboard power taking of docking, become, by DC-DC line transfer in plate, 3.3V voltage, the 0.9V/1.8V voltage of Expander use that PSOC uses.
SASExpander board size 188x140mm, thickness of slab 2mm, use 8 plywood designs.
In addition to the technical characteristic described in description, it is the known technology of those skilled in the art.
