Abstract
The invention discloses a method for testing the read-write performance of a PMC Raid card. Comparison testing scripts are complied, so a comparison data test on the read-write performance of the PMC Raid car is additionally performed while testing is carried out through a read-write testing script provided by a user, and therefore the accuracy of testing the read-write performance can be guaranteed. According to the method, the read-write performance of the PMC Raid card on a server is tested through the read-write performance script, the read-write testing script provided by the user can be compared and checked with the read-write performance script, the difference of results is small; accordingly, the accuracy of testing and checking can be guaranteed, and the accuracy of read-write testing of the PMC Raid card is further improved.
Description
Technical field
The present invention relates to computer technology, specifically a kind of reading/writing method testing PMC Raid card.
Background technology
RAID be a kind of polylith independently physical hard disk to combine differently formation logic hard disk, thus provide and have higher performance than single hard disk and the technology of data redundancy is provided.RAID card is just used to the board realizing RAID function, is normally made up of a series of spare parts such as I/O processor, hard disk controller, hard disk connector and buffer memorys.The RAID function that different RAID card is supported is different.Support RAlD0, RAID1, RAID3, RAID4, RAID5, RAID10 not.RAID card can allow a lot of disc driver transmit data simultaneously, and these disc drivers are logically disc drivers, so use RAID can reach single disc driver several times, tens times even speed of hundreds of times.
In order to better test PMC Raid card readwrite performance on the server, the present invention proposes a kind of reading/writing method testing PMC Raid card.
Summary of the invention
We are bright provides a kind of reading/writing method testing PMC Raid card, its object is to the accuracy strengthening test PMC Raid card readwrite performance.
A kind of reading/writing method testing PMC Raid card of the present invention, the technical scheme solving the problems of the technologies described above employing is as follows: the reading/writing method of described test PMC Raid card, by writing contrast test script, while the readwrite tests script test using client to provide, increase and the correlation data of PMC Raid card readwrite performance is tested, guarantee the accuracy of test reading write performance.
The present invention tests the reading/writing method of PMC Raid card, first a contrast test script is write, and the contrast test script write can be applied in the readwrite tests of PMC Raid card normally, use the readwrite performance of the contrast test script test PMC Raid card write, then use the readwrite tests script test result of client; By contrast test result, both are more or less the same and all meet the readwrite tests requirement of client, can ensure the accuracy of testing authentication.
The beneficial effect that the reading/writing method of a kind of PMC of test Raid card of the present invention compared with prior art has is: by the reading/writing method of this test PMC Raid card, test PMC Raid card readwrite performance is on the server realized by readwrite performance script, the readwrite tests script that can provide with client carries out contrast verification, both are more or less the same at result, the accuracy of testing authentication can be ensured, strengthen the accuracy of PMC Raid card readwrite tests further.
Accompanying drawing explanation
Accompanying drawing 1 is described contrast test script;
Accompanying drawing 2 is the log document using contrast test script Self-adaptive;
Accompanying drawing 3 is the readwrite tests script test result document using client.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, a kind of reading/writing method testing PMC Raid card of the present invention is further described.
A kind of reading/writing method testing PMC Raid card of the present invention, while the readwrite tests script test using client to provide, by writing a contrast test script, increasing and the correlation data of PMC Raid card readwrite performance is tested, ensure the accuracy of test reading write performance.
Embodiment:
A kind of reading/writing method testing PMC Raid card described in the present embodiment, first writes a contrast test script as shown in Figure 1, uses the contrast test script write to test PMC Raid card---and 6805 steps are as follows:
Step one: by contrast test script by USB flash disk copy to redhat OS /root in;
Step 2: under Redhat system, opt size default setting is maximum;
Step 3: carry opt;
Step 4: input command sh testdd.sh;
Step 5: switch by ctrl+Alt+F2 and log in rear input iostat – t 1, wait for that disk read-write test terminates;
Step 6: tested and generated log document as shown in Figure 2:
Step 7: open log document, read: 1GB/s writes 845MB/s;
Step 8: the readwrite tests script test result using client, as shown in Figure 3, reads: 1.2GB/s writes: 886MB/s.
By contrast test result, both all meet the readwrite tests requirement of client, and the contrast test script write can be applied in the readwrite tests of PMC Raid card normally.By testing the reading/writing method of PMC Raid card described in this example, while the readwrite tests script test using client to provide, by the contrast test script write, the result that the readwrite tests script of test result and client is measured is more or less the same, and can ensure the accuracy of testing authentication.
Above-mentioned embodiment is only concrete case of the present invention; scope of patent protection of the present invention includes but not limited to above-mentioned embodiment; any claims according to the invention and any person of an ordinary skill in the technical field to its suitable change done or replacement, all should fall into scope of patent protection of the present invention.
Claims (4)
