Description
Technical field
The utility model relates to the expansion of a kind of server data hard disk, specifically a kind of SAS power board for expanding disk array.
Background technology
SAS(mode connected in series) be developed by parallel SCSI physical store interface.Compared with parallel mode, serial mode provides communication transfer speeds and configuring more easily faster.In addition SerialAttachedSCSI supports mutually compatible with Serial ATA device, and both can use similar cable as transmission medium.SAS supports point to point connect, and allows multiple port on single controller, can be based upon mainboard and also can add in addition.This technology is based upon on powerful parallel SCSI communication technology basis.SAS adopts the point-to-point interconnection of serial ATA (SATA) Thin cable, thus does not need to set up daisy chain in computer systems, which and just can realize cable Route Selection simply; SAS power board is mainly used in server stores, and the development of adjoint large data and memory technology and application, electronic data amount is expanded rapidly, and mass-storage system occurs thereupon.And traditional memory capacity low cost is high, and memory capacity can not be changed flexibly, voltage can not be changed according to the demand of power supply for SAS power board, cause a lot of inconvenience like this.
Summary of the invention
Technical assignment of the present utility model is for above deficiency, providing a kind of SAS power board for expanding disk array, solving above technical matters.
The utility model solves the technical scheme that its technical matters adopts: the plate shape of this SAS power board is rectangle, and the left side on described plate body surface is provided with five interface connectors, and described interface connector is evenly distributed successively from top to bottom; Described plate body surface middle part is provided with SAS control chip, is provided with five supply modules on the right side of SAS control chip; The right side edge place of described plate body is provided with power supply signal connector, to power 12V transmission of control signals for giving this SAS power board.
Described interface connector is followed successively by an X1 standard SAS hard-disk interface connector and four X4 standard SAS hard-disk interface connectors from top to bottom on plate body surface, described X1 standard SAS hard-disk interface connector has an interface, each X4 standard SAS hard-disk interface connector has four interfaces, wherein, X1 standard SAS hard-disk interface connector is for connecting cpu node, cpu node is used for processing data and calculates and complete and the read-write of data between hard disk, a cpu node, the expansion of maximum 64 hard disks can be realized, the hard disk extended deployment density effectively improved; The JBOD node of SAS hard disk disposed by X4 standard SAS hard-disk interface connector for connecting, JBOD node is hard disk serial, realizes power supply and the deployment of hard disk.Can according to the needs of practical application, determine the quantity of JBOD, depend on the requirement of system application scenario to hard disk quantity and capacity.
Five described supply modules are respectively 1.005V supply module, 1.8V supply module, 0.925V supply module, P5V supply module and P3V3_AUX supply module, make this SAS power board have 12V and turn 3.3V_STBY, 12V and turn 5V, 12V and turn 0.925V, 12V and turn 3.3V, 12V and turn 1.8V and 12V and turn these 6 groups of DC/DC circuits of 1.005V; On this SAS power board, the 12V realized turns 0.925V step-down circuit, adopts two-phase power supply plan, is used for meeting the larger current needs of exchange chip.Hard disk power pack not at SAS power board, but realizes on JBOD board.
A kind of SAS power board for expanding disk array of the present utility model compared to the prior art, there is following beneficial effect: be connected formed system by JOBD, cpu node with this SAS power board, can meet the field such as server, storage comparatively large to hard-disk capacity demand, and system need connect the needs of the application scenarios of a greater number hard disk; The quantity of JBOD depends on the requirement of system application scenario to hard disk quantity and capacity; Only need a cpu node, the expansion of maximum 64 hard disks can be realized, the hard disk extended deployment density effectively improved; On this SAS power board, we according to the demand of SAS power board to power supply, can be completed by the conversion of the 12V inputted to required voltage by supply module.This shows, this SAS power board can meet the demand of server, the many hard disk connections of field of storage, is widely used.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Accompanying drawing 1 is a kind of structured flowchart of the SAS power board for expanding disk array.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of SAS power board for expanding disk array of the present utility model, the shape of this SAS power board plate body is rectangle, the left side on described plate body surface is provided with five interface connectors, described interface connector is followed successively by an X1 standard SAS hard-disk interface connector and four X4 standard SAS hard-disk interface connectors from top to bottom, described X1 standard SAS hard-disk interface connector has an interface, and each X4 standard SAS hard-disk interface connector has four interfaces.Described plate body surface middle part is provided with SAS control chip, is respectively arranged with 1.005V supply module, 1.8V supply module, 0.925V supply module, P5V supply module and P3V3_AUX supply module on the right side of SAS control chip.The right side edge place of described plate body is provided with power supply signal connector.
