Description
Technical field
The present invention relates to disk array storage system, relate in particular to the switching on and shutting down time sequence control device that is used for raid-array.
Background technology
Raid-array (Redundant Array of Independent Disks) is called for short the RAID disk array, be (to divide Hardware by RAID Controller with N platform hard disk, Software) be combined into the jumbo hard disk of virtual separate unit and use, its characteristic is the reading speed quickening simultaneously of N platform hard disk and fault-tolerance (Fault Tolerant) is provided.
RAID is that storage system (the perhaps built-in storage of server) is brought huge interests, and wherein improving transfer rate and fault tolerance is provided is biggest advantage.RAID has improved transfer rate by using a plurality of disks simultaneously.RAID significantly improves the data throughout (Throughput) of storage system by storage simultaneously and reading of data on a plurality of disks.In RAID, can allow a lot of disc drivers transmit data simultaneously, and these disc drivers logically are disc drivers, so use RAID can reach the speed of several times of single disc drivers, tens times even hundreds of times.By data check, RAID can provide fault tolerance.Because common disk drive can't provide fault tolerance, if do not comprise CRC (cyclic redundancy check (CRC)) sign indicating number that writes on the disk.RAID is fault-tolerant to be to be based upon on the hardware fault-tolerant function of each disc driver, so it provides higher security.The measure of comparatively complete mutual verification/recoverys is all arranged, or even direct mutual mirror back-up in a lot of RAID modes, thereby improved the tolerance of RAID system greatly, improved the stable redundancy of system.
The basic composition of RAID system is that head adds a plurality of extension cabinet, and the head unification provides stores service (comprising the realization of RAID function and storage protocol), and extension cabinet only realizes the expansion of disk position.Because it is one of function of head that RAID calculates, and RAID calculates the disk that need utilize in the extension cabinet, if the startup sequential of head and extension cabinet can not be controlled, causes the storage system fault probably, cisco unity malfunction, even the ruined serious consequence of data.
Such as, in a kind of more common configuration, head is connected by MINI SAS line with extension cabinet, and head has the RAID function, and extension cabinet only realizes the disk expanded function.When system selected a plurality of disks to be RAID, all RAID computing functions were all realized by host header, that is to say that head must all find disk in the head cabinet and the disk in the extension cabinet, and is configured and calculates.If the RAID controller starts, and when searching disk in the RAID group, but disk is not ready for, and will cause RAID to lose efficacy.RAID lost efficacy, and was certain to cause system to move, and data can't read.Under the serious situation, RAID can be destroyed, and all data are all lost.
In current RAID storage system, all be logic and the sequential that realizes start by manual, device start, restart with shutdown process very complicated.Any operating mistake may cause serious consequence.And if equipment loses power supply, when powering up automatically again, the device start sequential is in uncontrollable state, brings potential threat to equipment operation.
Summary of the invention
The present invention is intended to solve the above problems, the present invention proposes a kind of hard-wired switching on and shutting down time sequence control device, detect the power-up state of head, the electrifying startup logic of robot brain head and extension cabinet avoids causing because start sequence problem the fault of storage system.
According to one embodiment of the invention, a kind of switching on and shutting down time sequence control device of disk array storage system is proposed, be used for the disk array storage system formed by head and several extension cabinet, this switching on and shutting down time sequence control device comprises:
The head controller, be installed in the PCI slot of head and obtain power supply by the PCI slot, this head controller comprises the input interface that receives input and the output interface of output order, and output interface comprises to the head sub-interface of head output order with to the extension cabinet sub-interface of extension cabinet output order;
The extension cabinet controller, be installed in the extension cabinet, an extension cabinet controller is installed in each extension cabinet, the showcase controller that is installed in each extension cabinet is connected to each other in the mode of cascade, each extension cabinet controller comprises input end and output terminal, the input end of the extension cabinet controller of the first order is connected to the extension cabinet sub-interface of head controller, the input end of all the other extension cabinet controllers at different levels connects the output terminal of upper level extension cabinet controller, the output terminal of the extension cabinet controller of afterbody is vacant, and the output terminal of all the other extension cabinet controllers at different levels connects the input end of next stage extension cabinet controller.
In one embodiment, the input interface of head controller is the contact pin interface that is connected to the cabinet button; The output interface of head controller is the serial ports jack devices.
In one embodiment, the head sub-interface is to the lasting reset signal of head output; The direct supply of extension cabinet sub-interface output 5V.The extension cabinet sub-interface also comprises an electric capacity.
The switching on and shutting down time sequence control device of disk array storage system of the present invention has been realized the startup of head and extension cabinet and the sequential of closing by hardware, can be in the normal startup and the shutoff that need not to realize under the artificial situation about participating in head and extension cabinet, the operate as normal that guarantees head and extension cabinet has been stopped the risk that maloperation causes loss of data.After the outage of RAID system exception, the normal back of service restoration memory device can start voluntarily, need not to interfere the time that stops to serve of greatly reducing system
