Abstract
The utility model provides a redundant array of independent disks (RAID) card with data caching protection and belongs to technical field of computers. The RAID card structurally comprises a common serial attached SCSI (SAS) RAID card. The SAS RAID card is connected with five internal memory particle chips. The SAS RAID card is further connected with a standby lithium battery. A complex programmable logic device (CPID) on a printed circuit board (PCB) of the SAS RAID card is provided with an SAS hard disk independent locating circuit. Compared with the prior art, the RAID card with the data caching protection has the advantages of being reasonable in design, simple in structure, convenient to use and the like, is capable of providing functions of data caching, working condition indication, hot plug, fault alarm and the like, and is high in overall efficiency, thereby effectively protecting the data and enhancing usability and safety of products.
Description
Technical field
The utility model relates to a kind of RAID card of field of computer technology, a kind of specifically RAID card with the metadata cache protection.
Background technology
Increase along with the user environment data throughout is huge, the hard disk quantity of separate unit server configures and capacity have all had and have increased by a wide margin, the meaning of effective reliable transmission of realization user data is obvious day by day, and the RAID card has become a significant concern point that influences complete machine performance and stability.Ubiquitous deficiency is in the RAID card of prior art: because the transfer rate of SAS 2.0 signals is 6Gb/s, such high-frequency signal is subjected to extraneous interference easily, the SAS RAID card that uses adopts the mode of top layer cabling at present, poor anti jamming capability, can't guarantee signal integrity, the signal cross-talk ability is stronger; When carrying out Large Volume Data when transmission between hard disk and mainboard, if when running into system's power down, the data in the hardware data buffers can cause loses, and data can not get effective protection; The direct-connected mode of present hard disk and mainboard, whole efficiency can rely on and hard disk, and efficient can't promote; Present SAS RAID card generally has only Power pilot lamp, relay indicating light and the pilot lamp that reports an error, in some large-scale clusters and high-capacity storage application, the client need operate the hard disk that certain sheet is formulated, often take to carry out with the method for software matrix contrast, but this method ratio is easier to make mistakes, if to the data security than higher application in, this way has very high risk
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, provides a kind of simple in structure, design cleverly with the RAID card of metadata cache protection.
The technical solution of the utility model realizes in the following manner; this a kind of RAID card with the metadata cache protection; its structure comprises general SAS RAID card; described SAS RAID links and is connected to internal memory particle chip; this internal memory particle chip design has five; described SAS RAID card also is connected with standby lithium battery, and design has SAS hard disk location-independent circuit among the CPLD on the pcb board of this SASRAID card.
What described SAS RAID card adopted is 12 layers of pcb board design.
The beneficial effect that the utility model is compared with prior art produced is:
It is anti-interference that a kind of RAID card design with the metadata cache protection of the present utility model has 12 laminates, and signals layer is kept apart, and both strengthened antijamming capability, guaranteed the integrality of signal again, reduced the cross talk effects of signal; Internal memory particle chip is formed hardware data buffers, and fashionable as can't in time writing when hard disc data, system needn't wait writing of pending data, and the hardware data buffers of transferring to SAS RAID card gets final product, and realizes the asynchronism of data manipulation, improves whole efficiency; Be connected with reserve battery, when running into system's power down, the SASRAID card standby lithium battery that can automatically switch continues to refresh the internal memory particle, does not lose to guarantee the data in the hardware data buffers, plays the purpose of protected data; From the agreement of SAS, the function by CPLD on the plate has realized SAS hard disk location-independent has strengthened the ease for use and the security of product.
Description of drawings
Accompanying drawing 1 is a structured flowchart of the present utility model.
Mark in the accompanying drawing is represented respectively:
1, standby lithium battery, 2, internal memory particle chip, 3, SAS RAID card, 4, SAS hard disk location-independent circuit.
Embodiment
Below in conjunction with accompanying drawing a kind of RAID card with the metadata cache protection of the present utility model is done following detailed description the in detail.
As shown in Figure 1; this a kind of RAID card with the metadata cache protection; its structure comprises general SASRAID card 3; described SAS RAID card 3 is connected with internal memory particle chip 2; these internal memory particle chip 2 designs have five; described SAS RAID card 3 also is connected with standby lithium battery 1, and design has SAS hard disk location-independent circuit 4 among the CPLD on the pcb board of this SAS RAID card 3, has realized the function of SAS hard disk location-independent.
What described SAS RAID card 3 adopted is 12 layers of pcb boards design, and high speed signal all is distributed in internal layer like this, four independently bus plane and stratum, signals layer is kept apart, both strengthen antijamming capability, guaranteed the integrality of signal again, reduced the cross talk effects of signal.
The utility model just can provide the indication of metadata cache, duty, hot-swappable, fault alarm or the like function like this, has good value for applications.
Claims (2)
1. RAID card with metadata cache protection; comprise general SAS RAID card; it is characterized in that described SAS RAID links is connected to internal memory particle chip; this internal memory particle chip design has five; described SASRAID card also is connected with standby lithium battery, and design has SAS hard disk location-independent circuit among the CPLD on the pcb board of this SAS RAID card.
2. a kind of RAID card with the metadata cache protection according to claim 1, what it is characterized in that described SAS RAID card employing is 12 layers of pcb boards design.
