Description
Technical field
The present invention relates to technical field of measurement and test, more particularly, to a kind of method and apparatus of testing magnetic disc array.
Background technology
One disk array includes controller and physical disk cabinet, and controller is used for running control software and various algorithm,
It is located in controller for data cached cache memory cache；And physical disk cabinet is deposited under the control of the controller
Storage data.Under normal circumstances, when disk array receives an io read request of client, if the data of request is in speed buffering
Memorizer cache does not hit, then be read into cache the data of request from the physical disk cabinet of disk array, then
Returned from cache to client；When disk array receives one io write request of client, data to be written into is write
In cache, and return successful respond to client, afterwards according to algorithm controls then by cache, this is to be written in certain time
Data writes in the physical disk cabinet in disk array.According to this operation characteristic of disk array, the survey of existing disk array
Method for testing is: simple emulation io read-write operation, it may be assumed that sending io write operation order to disk array, receives disk array and returns
Successful respond；Send the io read operation order of the data for reading write again to disk array, receive disk array and return
Data.In prior art, in said process, will not verify whether the data of write is consistent with the data reading.
In actual test, in order to obtain a higher test value, the producer of tested disk array is possible to change
The control software of disk array.Such as, for io read operation order, even if cache does not hit, it also will not be from disk array
Physical disk cabinet in read data and return to client again, but directly return other data in cache to client.
It can be seen that, existing this method of testing can not effectively detect this abnormal running status of disk array, from
And the numerical value virtual height tested can be led to, do not meet its practical operation situation.
In addition, existing test model is achieved in that being realized with the mode generating random number, as shown in figure 1, be existing
There is the schematic diagram realizing test in technology using the mode generating random number.Wherein, test model generates and comprises 100 elements
Array, each element represents a kind of specific access control policy, and the random number according to generating determines the corresponding element of selection
The access control policy representing, and according to the access control policy determining, disk array is tested.In actual applications, than
As a Transaction Processing oltp model, it generates the array comprising from 1 to 100, and this array represents an access control plan
Slightly group, the access control policy that wherein " 1-20 " represents is " reading 8k byte with random access manner ", the access that " 21-65 " represents
Control strategy is " reading 4k byte with random access manner ", and the access control policy that " 66-80 " represents is " with random access manner
Write 8k byte ", the access control policy that " 81-90 " represents is " writing 64k byte with sequential access mode ", and " 91-100 " represents
Access control policy is " reading 64k byte with sequential access mode ".It can be seen that, for the access control set by this oltp model
In strategy, the random read operation that the random read operation of 8k byte accounts for 20%, 4k byte accounts for the random writing operations of 45%, 8k byte and accounts for
The order write operation that the order read operation of 15%, 64k byte accounts for 10%, 64k byte accounts for 10%.
In actual test, the shared ratio in access control policy group of the different access control strategy of only its foundation
When meeting regulation ratio, just can obtain the most accurate test result.But, due to having no idea to control the random of generation on demand
Count and make the access control policy of test institute foundation reach such ratio, such as when the mode using generation random number is upper
State when disk array being tested in oltp model, if having 30 randoms number to fall into [1,20] in the 100 of generation randoms number
This is interval, then the access control policy corresponding to " 1-20 " will account for 30%, thus the random number generating is pointed accesses control
The shared ratio in access control policy group of system strategy is doomed will not be very accurate, therefore cannot realize well in above-mentioned model
The purpose of middle testing magnetic disc array.

Step 55, judges whether io action type specified in access control policy is read operation, if so, execution step
56, otherwise execution step 59.
Step 56, executes io read operation, returns and reads data；
Step 57, judges the write data specified by data block to be visited and executes reading according to this access control policy
Whether the reading data returning after operation mates, if so, execution step 510, otherwise execution step 58.
Step 58, the running status of this disk array is abnormal, and abnormal number adds 1, execution step 510.
Step 59, executes io write operation, and returns successful respond.
Step 510, judges whether to travel through whole access control policies, and if so, then test terminates, and obtains test result, no
Then return execution step 52.Wherein, this test result can obtain according to the last abnormal number determining.Such as, Ke Yigen
According to the relatively more last abnormal number determining and the outlier threshold pre-setting, if the last abnormal number determining is more than or equal to pre-setting
Outlier threshold, then test result is that this disk array running status is abnormal, if the last abnormal number determining is less than pre-setting
Outlier threshold, then test result be this disk array running status normal.
