Description
Technical field
The utility model relates to a kind of disc array system that is used for long term data storage.
Background technology
Along with constantly widening of computer application field, the user is increasing for the capacity requirement of storage system, and more and more higher to its reliability, availability requirement, rate request is also more and more faster.At the challenge that storage system faced, people expect forming heavy surplus array RAID (the Redundant Array of Independent Disk) disk array of independent disk to obtain high number biography rate and large storage capacity with a plurality of disc drivers.But owing to having relative low price, access speed, disk array reaches advantages such as random access soon, so disk array has a large amount of application in online data data storage and data backup field.Yet in the field that off-line data long-term (several years is to many decades) is preserved, ordinary magnetic disc or disk array are because have the following disadvantages, and fail to be widely used: 1, as online with the long preservation data disk, keeping disk to switch on for a long time needs to consume in a large number electric power, and will cause disk to occur wrong and necessary the replacing in the short relatively time.2, long-term off-line is placed the influence (as magnetic field or electric shock) that the disk of preserving is subjected to extraneous factor easily and is caused loss of data, or the influence of internal factor (as the deposition of self bearing oil or mechanical arm aging) and cause disk failures.3, humidity and air oxidation cause the component wear of long term exposure on airborne disk to cause disk failures easily.4, the extruding of collision or external force causes disk failures easily.5, static hits and causes disk failures easily.6, ordinary magnetic disc itself is a rewritable media.Exposed disk is easy to be read or write by undelegated people cause data to reveal or lose.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, the disc array system that is used for long term data storage that provides a kind of and can not damage disk, can not cause data to reveal and lose.
The technical scheme that the utility model adopted is: the utility model comprises shell, several disks, controller, described several disks and described controller are arranged on described enclosure, described several disks are connected with data line by power lead with described controller, described shell is an all-sealed structure, be provided with vibration abatement between described shell and the described disk, described controller is connected with data-interface, power interface, described data-interface, it is protruding that described power interface penetrates the shell wall of described shell, and described controller comprises the hardware configuration circuit that uses wire jumper to be provided with.
Described housing exterior is provided with several LED light, and described several LED light are electrically connected with the controller that is arranged on described enclosure.
Described enclosure is filled with inert gas.
Be provided with metal framework in the described shell.
Described vibration abatement is spring or shockproof foam or the pouch of air is housed or the pouch of liquid is housed.
Paste or etching bar shaped identification code on the described outer shell outer wall.
Described data-interface is SATA or SAS or SCSI or network interface.
The beneficial effects of the utility model are: because controller described in the utility model comprises the hardware configuration circuit that uses wire jumper to be provided with, and setting can afterwards, making this that action is set so only may be made once to avoid the change configuration that data are damaged, so the utility model can be realized disposable system configuration.
Because the utility model is placed with vibration abatement between the shell wall of described shell and described disk; described vibration abatement is underbed (as spring or shockproof foam) the protection hard disk with buffer action; reduce hard disk and be subjected to the chance that external impacts causes damage; so the utility model shockproof effect is good, disk is not fragile.
Because shell of the present utility model is all-sealed structure, and inside is filled with inert gas, the end points place of per two described disks can use metal framework to reinforce in the described shell, so increase the ability of shell opposing external impacts, can strengthen the intensity of shell, can play resistance to compression, protection against the tide, dustproof, and the effect of anti-electromagnetism, can prevent that described shell build-in components is subjected to oxidation and the damage that causes.
Because global unique bar shaped identification code of this disc array system that the front end of shell described in the utility model and gland bonnet Pasting or etching can be read by bar code reader.Described bar shaped identification code also is stored on the controller, also can be read by outer computer, to make things convenient for computer software that this disc array system is managed, and the plant equipment identification of bar shaped identification code reader is conveniently arranged and extract the disc array system of appointment, so the utility model can not cause the data leakage and lose.Therefore the utility model has solved the traditional magnetic disk array system and has been used for the latent defect that long-term off-line is preserved data, and improved the feasibility of preserving at long-term off-line data greatly based on the storage system of disk, make the utility model have an opportunity to become to substitute and be mainly used in the storage medium that long term data is preserved at present based on CD or tape etc.
