Abstract

The utility model relates to a disk array connection structure, which comprises circuit boards, a disk array and transmission lines, wherein the disk array comprises a plurality of disk drives, and at least a connecting end is arranged in front of each of the disk drives; a DC power source and one end of an SATA are connected with the circuit boards, the other end is inserted in and connected with the connecting end in front of the disk drive to provided power source and control desired by the disk drives and reduce the number of connectors and the circuit boards used at disk array. Thus, the goal of reducing manufacture cost is achieved.

Description

The disk array syndeton

Technical field

The utility model relates to a kind of disk array syndeton, relates in particular to a kind of usage quantity that can reduce connector or circuit board, and reduces the disk array syndeton of cost of manufacture.

Background technology

The key concept of disk array (RAID) is to become an array in conjunction with a plurality of small-sized and cheap disc drivers, to reach the usefulness performance that a big and expensive disc driver can't accomplish or the target of redundancy.The array of this disc driver will be presented in the computing machine with a single logic storage unit or a disc driver.

The purpose of disk array is identical data storing different place in a plurality of disc drivers, and improves the usefulness of storage subsystem.Advantage is for providing better yield-power usefulness or fault-tolerance.By parallel being distributed in a plurality of entity disc drivers of workload can be reached usefulness preferably.And, when (or a plurality of) disc driver or sector generation problem, can in another disc driver, find the reflection copy of data by the data multiple operation, splendid fault-tolerance is arranged.

This disk array is in the hardware configuration utilization of reality, be to utilize a plurality of circuit boards, and on each circuit board, all be provided with the connector of pegging graft for disc driver, by winding displacement each circuit board is connected to master control circuit board again, as a kind of disclosed industrial computer hard drives interface arrangement; Or on a circuit board, be provided with a plurality of connectors of pegging graft for disc drivers, and connecting host board structure as the disclosed computer disk array computer of another kind, this circuit board is by winding displacement or be directly connected on the master control circuit board.Though above-mentioned connected mode can allow a plurality of disk drive group constitute disk drive array, but this connected mode will cause connector or circuit board usage quantity too much, cause cost of manufacture to increase, and make signal transmission number of contacts too much, also easily cause the signal attenuation in the signals transmission.

The utility model content

In order to solve the defective that exists in the above-mentioned prior art, fundamental purpose of the present utility model is to provide a kind of disk array syndeton, comprising: circuit board, disk array and transmission line; Described disk array comprises a plurality of disc drivers, and described each disc driver the place ahead is provided with at least one link, and this transmission line one end is connected with described circuit board, and the other end then is plugged on the link in disc driver the place ahead.

The utility model can allow connector or circuit board usage quantity reduce the connected mode redesign of disk drive array, to reduce cost of manufacture, also allows the transmission signals number of contacts reduce simultaneously, makes signal be difficult for decay when transmission.

Embodiment

Relevant technology contents of the present utility model and detailed description, existing conjunction with figs. is described as follows:

Fig. 1, Fig. 2 are respectively disk array syndeton configuration of the present utility model and front schematic view.As shown in Figure 1 and Figure 2: disk array syndeton of the present utility model comprises: housing 1; Be arranged on the circuit board 2 of housing 1 inside; Be arranged on the transmission line 4 of 3 of the disk array 3 of housing 1 inside and connecting circuit plate 2 and disk arrays.Utilize circuit board 2 to be connected with disk array 3, can reduce the usage quantity of connector and circuit board, reduce cost of manufacture simultaneously by transmission line 4.

Have accommodation space 11 in the housing 1, can order power supply unit 12, circuit board 2, disk array 3 and transmission line 4 be arranged on accommodation space 11 inside;

Circuit on the circuit board 2 includes at least: microprocessor, USB-HUB interface, USB-SATA translation interface and a plurality of electronic switch;

Disk array 3 comprises a plurality of disc drivers 31; Front panel at each disc driver 31 is provided with at least one link 32, is used for being connected with transmission line 4;

Transmission line 4 is for having the transmission line of SATA and DC power supply, and transmission line 4 one ends are connected with the electronic switch of circuit board 2, and the other end is connected with the link 32 of the front panel of disc driver 31.

Fig. 3, Fig. 4 are disk array syndeton of the present utility model side-looking and hardware configuration synoptic diagram.As shown in Figure 3, Figure 4: when the utility model when mounted, after first each disc driver 31 with disk array 3 is installed in housing 1 inside, again the other end of the transmission line 1 that circuit board 2 is connected by housing 1 below migration to disc driver 31 the place aheads, and on the link 32 of the front panel of the disc driver 31 of pegging graft again.This connected mode can reduce the usage quantity of connector and circuit board, allows cost of manufacture reduce.When reducing connector and circuit board usage quantity, similarly also reduce number of connections relatively, when signal is transmitted, can not cause signal attenuation again.Simultaneously, the maintenance person of being more convenient for maintenance perhaps allows the user install and use voluntarily.

After above-mentioned disk array syndeton was finished installation, circuit board 2 was connected with external computer device 6 by USB transmission line 5.When externally computer equipment 6 is exported control signals, after circuit board 2 receives processing, make any electronic switch on the circuit board 2 start, and start any disc driver 31 of disk array 3, allow external computer device 6 can carry out the data read or the storage of disc driver 31.When this disc driver 31 does not use, external computer device 6 is exported control signal again, after circuit board 2 is handled, close the power supply and the signal transmission of previous employed disc driver 31 to start electronic switch, to reach power saving and to reduce the heat that disc driver 31 runnings are produced, can reduce the spoilage of disc driver 31 and the serviceable life that prolongs disc driver 31.

The above only is a preferred embodiment of the present utility model, be not so promptly limit claim of the present utility model, the equivalent structure transformation that every utilization the utility model instructions and accompanying drawing content are done, directly or indirectly be used in other relevant technical field, all in like manner be included in the claim of the present utility model.
