And reliability, effectively raise many controlled storage system availabilities and reliability.
In order to preferably describe the data in controller, three kinds of states are introduced：Dirty1, dirty2 and mirror.
Dirty1 represents the data that controller is write as master control；When dirty2 represents the master controller fault of controller, by mirror image
The dirty data that data make into；Mirror is denoted as the data that backup controller is write.
Specifically, after writing I/O data and reaching i controllers, will first write I/O data and backup to i+1 controllers, then
I/O data write i controllers will be write again, and most backward server end return writes I/O operation and completes response, the algorithm for writing IO of employing
For：Master control receives write IO request, searches backup controller, and write IO request is forwarded to into backup controller；Backup controller
Write IO request is performed, and Backup Data is set to into mirror states, then write IO execution to master control return and complete；Master control is local
Write IO request is performed, and corresponding data is set to into dirty1 states, then write IO execution to server end return and complete；Algorithm is tied
Beam.
Specifically, when i controllers break down, the data of i-1 controllers are backuped in i+1 controllers,
Complete the backup procedure in the case of controller failure
The specific algorithm of backup procedure is as follows：
(1), the state of this controller modification failed controller is non-active；
(2), failure judgement controller is the backup controller of this controller, if continuing executing with, if it is not,
Jump to (4) step；
(3) the next active controllers of failed controller, are searched as the backup controller of this controller, this is controlled
The data of the dirty1 types of device processed, are mirrored to new backup controller；Jump to (6) step；
(4), failure judgement controller is the master controller of this controller, if continuing executing with, if it is not, jumping
Go to (6) step；
(5), the mirror categorical datas of itself are changed to into the data of dirty2 types, and are mirrored to the Standby control of itself
In device；
(6), algorithm terminates.
For example, Fig. 2 is that controller failure processes schematic diagram, and 1 represents No. 1 controller, and 2 represent No. 2 controllers, and 3 represent No. 3
Controller, 4 represent No. 4 controllers.When No. 2 controllers break down, the data in No. 1 controller are backuped to into No. 3 controls
In device.
Specifically, if the i controllers for breaking down recover normal, the data of i-1 controllers are backuped to into No. i control
In device, the Backup Data in i+1 controllers is deleted, complete and send out the backup procedure completed under controller recovery situation, it is standby
The specific algorithm of part process is as follows：
1st, the state of this controller modification recovery controller is active；
2nd, judge that recovery controller is the backup controller of this controller, if continuing executing with, if it is not, jumping
Go to step 4；
3rd, by the data image of this controller dirty1 and dirty2 type to recovery controller, former backup controller is deleted
In mirror image data；Jump to step 6；
4th, judge that recovery controller is the master controller of this controller, if continuing executing with, if it is not, redirecting
To step 6；
5th, the data of this controller dirty2 types are write into recovery controller, then by this controller dirty2 types
Data are changed to mirror, and discharge the corresponding mirror data of the backup controller of this controller.
For example, Fig. 3 is that controller recovers to process schematic diagram, and 1 represents No. 1 controller, and 2 represent No. 2 controllers, and 3 represent No. 3
Controller, 4 represent No. 4 controllers.When No. 2 controllers return to normal work from malfunction, by the number in No. 1 controller
According to backuping in No. 2 controllers, while deleting the data of No. 2 controllers backed up in No. 3 controllers.
This method is numbered to the controller in system, and each controller records the numbering of itself, institute in maintenance system
There is the controller numbering of other active.The mode of controller cache mirror back-up is the data of No. 1 controller in No. 2 controllers
Middle backup, the data of No. 2 controllers are backed up in No. 3 controllers, the like, the data of n controllers are in No. 1 controller
Backup, according to the numbering of controller, forms an order ring.After writing IO and reaching i controllers, i+ is first backed up data to
No. 1 controller, then writes again i controllers, finally just writes I/O operation to server end return and completes.When the event of i controllers
During barrier, i-1 controllers are backed up data in i+1 controllers automatically, it is ensured that the data in i-1 controllers have always standby
Part.The method both can guarantee that the data in controller had always backup, will not reduce writing the performance of I/O operation again, can also fit
For more controllers, therefore can effectively improve the availability and reliability of storage system.Do not reducing writing I/O operation
On the premise of performance, it is ensured that there is backup at the data moment in each controller, reasonably taken into account storage system performance and
Reliability, effectively raises many controlled storage system availabilities and reliability.

Wherein, backup module will be specifically for after writing I/O data and reaching i controllers, first writing I/O data and backup to i+
No. 1 controller, then will write again I/O data write i controllers, and most backward server end return writes I/O operation and completes response.
Specifically, controller numbering module is used for safeguarding globally unique, consistent system controller numbering in the controller
View, each controller records the numbering of oneself, at the same in maintenance system other controllers numbering and state (active or
Non-active), the total n of controller and in system；Each controller order selects the control of itself next active
Backup controller of the device as oneself.When there is controller failure in system, controller needs the state for changing failed controller.
Backup module is used for processing the read-write IO for being issued to the controller, reads IO directly from locally reading and return；Write IO
The backup controller of oneself is first found, and writes backup controller, then handwritten copy ground again, most backward controller returns that to write IO complete
Into.
Fisrt fault processing module is used in processing system the situation for having controller failure：First by the shape of failed controller
State is revised as non-active, and then failure judgement controller is the backup controller of this controller, if it is, by itself
Dirty data write the next active controllers of failed controller and backed up；If it is not, failure judgement controller is
It is not the master controller of this controller, if it is, the mirror image data of itself is changed to into dirty data and the Standby control of itself is write
In device, if not master controller, then process terminates.
Recover the situation that controller recovers that processing module is used for being broken down in processing system：The control that will recover first
Device status modifier is active, then judges that whether this controller is the master control of recovery controller, if it is, by itself dirty data
In writing recovery controller, and discharge the mirror image data in former backup controller；If it is not, judging whether itself recovers
The backup controller of controller, if it is, itself dirty data is write into recovery controller, and is changed to mirror image number by itself dirty data
According to if it is not, then process terminates.
