Description

A kind of shared storage device based on SRIO interfaces

Technical field

The utility model relates to storage device technical fields, and in particular to a kind of shared storage based on SRIO interfaces Equipment.

Background technology

As the continuous development of memory technology records some specific source datas in fields such as communication, military project, national defence There are increasingly higher demands with storage, to all kinds of storage schemes occur, and in these specific application fields, due to The characteristics of SRIO technical maturities are high, reliability is high, speed is fast, high efficiency, low cost, SRIO storage schemes increasingly occupy emphatically The status wanted, therefore interconnection often selects SRIO buses, and SRIO buses are easy to affix one's name in cabinet inside.Based on this, It is particularly necessary to design a kind of autonomous controllable high-performance storage device of the shared storage device based on SRIO interfaces.

Invention content

In view of the shortcomings of the prior art, the utility model aims to provide a kind of being total to based on SRIO interfaces Storage device is enjoyed, simple in structure, reasonable design is flexibly easy-to-use, low in energy consumption, scalability is strong, and read or write speed is high, and there are data to protect Protective function, safely controllable, highly practical, use easy to spread.

To achieve the goals above, the utility model is to realize by the following technical solutions：One kind is connect based on SRIO Mouthful shared storage device, including FPGA main control modules, mSATA electric boards and DDR3 shared drives, FPGA main control modules with it is more The connection of a mSATA electric boards, FPGA main control modules also connects with DDR3 shared drives, FPGA main control modules by srio interfaces and CPU hosts connect, and FPGA main control modules are connected to BMC controllers.

Preferably, the mSATA electric boards by SATA interface carry on FPGA main control modules, FPGA master control moulds Polylith mSATA electric boards are invented unified memory space by block by RAID algorithm.

Preferably, the SRIO chains road between the PGA main control modules and CPU hosts, definition have a kind of data to pass Defeated agreement, for carrying the format packet of the functions such as read-write erasing.

The beneficial effects of the utility model：This equipment uses the master control solution based on FPGA, and flexible design is easy-to-use, work( Consume that low, scalability is strong, safely controllable, performance is high, facilitates cabinet inside to affix one's name to, especially in data record storage, mobile hard disk etc. Field can be used as the storage solution for the high efficiency, low cost that more hosts access, and applicability is wide.

Description of the drawings

It is described in detail the utility model with reference to the accompanying drawings and detailed description；

Fig. 1 is core internal functional block diagram of the utility model based on FPGA, SRIO；

Fig. 2 is the structure diagram of the utility model.

Specific implementation mode

To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below In conjunction with specific implementation mode, the utility model is expanded on further.

Referring to Fig.1-2, present embodiment uses following technical scheme：A kind of shared storage based on SRIO interfaces is set It is standby, including FPGA main control modules 1, mSATA electric boards 2 and DDR3 shared drives 3, FPGA main control modules 1 by SATA interface with Multiple mSATA electric boards 2 connect, and FPGA main control modules 1 are also connect with DDR3 shared drives 3, and FPGA main control modules 1 pass through srio Interface is connect with CPU hosts 4, and FPGA main control modules 1 are connected to BMC controllers 5.

Present embodiment FPGA main control modules 1 pass through srio as main control data processing module, CPU hosts 4 Connect with FPGA main control modules 1, and access the mSATA electric boards 2 of its carry above by FPGA main control modules 1, realizes great Rong Data processing and storage are measured, and supports capacity extension.Inside FPGA main control modules 1, need to realize based on SRIO interfaces The command functions such as read-write erasing, and corresponding read-write operation mSATA electric boards 2 can be converted to according to order, there is operation host real Now corresponding file system distributes corresponding read/write address；FPGA main control modules 1 realize corresponding RAID algorithm in inside, will Polylith mSATA electric boards 2 invent unified memory space, are externally presented as one piece of storage dish, are led according to operation inside FPGA The functions such as the collision detection control of more hosts may be implemented in the difference of machine.

In addition, on SRIO chains road between PGA main control modules 1 and CPU hosts 4, definition has a kind of Data Transport Protocol, For carrying the format packet of the functions such as read-write erasing, the order and data packet that CPU hosts 4 will be sent, which constructs, is stored in host Memory in, notice memory module go to obtain by dma operation, the occupancy of host CPU can be reduced in this way, promote host Service efficiency, while efficiency of transmission and speed are improved, operating protocol of the memory module based on agreement is pressed after format Packet analyzing It is distributed to the mSATA electric boards 2 of rear class according to standard SATA protocols, completes the operations such as the read-write of data；Entire storage mode is similar It is stored in SAN, host is based on block storage mode and operates equipment, and bottom link channel is SRIO, can define this storage mode For SRIOSAN.

Present embodiment uses the design structure of FPGA+mSATA electric boards, supports expansible memory capacity, CPU Carried out data transmission by srio and the equipment, the requirement of domestic large capacity, high-performance storage device can be met completely.Originally it sets It is standby to have following feature：(1) external interface is SRIO interfaces, without any other interface；(2) support more hosts are shared to visit It asks；(3) there is data protection function；(4) read or write speed is high；(5) ultralow power consumption.
