Abstract
The invention provides a design method of improved PCIE (Peripheral Component Interface Express) switch management module data storage, and belongs to the field of data storage. An onboard Flash storage chip is adopted to replace an original M-SATA (Mini-Serial ATA International Organization) hard disk, meanwhile, a power failure protection circuit is increased, so that space in a board is saved to be favorable for PCB (Printed Circuit Board) locating and wiring, meanwhile, cost can be lowered to improve the competitiveness of a product, and therefore, a power failure protection mechanism can guarantee the safety of data being transmitted.
Description
Technical field
The present invention relates to data storage technology, relate in particular to establishing of a kind of PCIE of improvement switch management module data storageMeter method.
Background technology
Nearly 3-5, it is fast-developing that data explosion increases requirement storage. Storage industry chain longitudinally constantly shortens, industryChain is simplified, link is monopolized, and new main body and creator add relative being squeezed, and runs into high threshold, and storage becomesThe performance bottleneck of data center. In order to reverse this quagmire, it is high that my company proposes key business data taking AS18000 as corePerformance storage solution, supports SSD+HDD layering storage and complete two kinds of configuration modes of flash memory, and the data response of 1,000,000 grades is providedSpeed, allow the running of whole data center more efficiently, more smooth and easy. The PCIE switch of our independent research is just in order to realizeAS18000 front end PCIE Switching Module and server high speed is interconnected arises at the historic moment.
Existing PCIE switch management module, in order to realize data storage, mostly adopts SSD or M-SATA hard diskScheme. Existing scheme is as follows: 1, CPU calls the system, program and the data that are stored on hard disk by internal memory. 2, due to internal memoryCharged storage (once power-off data will disappear), and finite capacity, so just want long-time stored routine or dataNeed to use hard disk. 3 hard disks also can affect system speed, because system reading out data deposit internal memory in by bus from hard diskSpeed also can affect the speed of system operation. But existing scheme has its shortcoming: 1 existing scheme cost is high, takies in plateSpace is large, and hard disk dismounting is inconvenient. 2 in the time that CPU carries out reading and writing data by internal memory to hard disk, the unexpected power down of machine, nowCan cause the loss of data of communicating by letter, lack power down protection mechanism.
Summary of the invention
In order to address this problem, the present invention proposes the design side of a kind of PCIE of improvement switch management module data storageMethod.
Design of the present invention is, in PCIE switch management module, to adopt plate to carry Flash storage chip as depositingStorage node, increases power-down protection circuit simultaneously around Flash storage chip, has so not only saved the space in plate, favourableIn PCB placement-and-routing, and can reduce costs the competitiveness that improves product, power down protection mechanism can be guaranteed to pass simultaneouslyThe security of transmission of data.
The present invention no longer adopts traditional SSD or the M-SATA memory node as PCIE switch management module, andTo adopt the FLASH chip that carries of plate as memory node.
The FLASH die size that plate carries is 1/3 of M-SATA or SSD hard disk, can save like this space in plate, favourableIn the placement-and-routing of PCB, power source design is optimized, reduce the interference of power supply to high speed signal.
If all adopt FLASH chip and the M-SATA of 32G, FLSAH chip cost can reduce half left and right so, favourableIn the competitiveness of improving product.
For chip design power-down protection circuit: increase the smooth electric capacity of 5 hundreds of microfarads at the power supply circuits that are chip. WhenWhen power down, electric capacity still can be powered, and the data that guarantee is being transmitted can not be lost.
The invention has the beneficial effects as follows.
1) save space in plate, be conducive to the placement-and-routing of PCB, power source design has been optimized, reduced power supply to heightThe interference of speed signal.
2) reduce costs, improve the competitiveness of product.
3) in the time of machine power down, can ensure the security of data.
