Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
The embodiment of the present invention one discloses a kind of performance of storage system decision method, shown in Figure 1, this method, including：
Step S11：Whether the asynchronous replication of detection storage system stops；
Step S12：If asynchronous replication stops, whether detection storage system there is IO time-out；
Step S13：If IO time-out occurs in storage system, judge that storage system is in overload.
In the present embodiment, it is whether the asynchronous replication for detecting storage system stops first, if storage system is asynchronous
Normal operation is replicated, illustrates the functional of storage system, if the asynchronous replication of storage system stops, illustrating storage system
Operation there is a problem because asynchronous replication is to copy data to storage system from a memory space of storage system
Another memory space, it may appear that temporal delay, this usual time delay is by network bandwidth and system load situation
Determined etc. factor.And during storage system carries out asynchronous replication, timer can be to the bad cycle in storage system
Counted, and when the counting of timer reaches certain threshold value, system can judge the self performance deficiency of storage system,
Asynchronous replication is closed immediately, and reports IO overtime.The present invention is exactly come to storage system using this feature of storage system
Performance detected.
Among the method for traditional detection performance of storage system, the result of detection is often sightless for user, and
And the result accuracy of detection is relatively low, live effect is poor.And the performance of storage system is detected using the method in the present invention
When, the result of detection can be reacted on the page of operating system in real time, improve Consumer's Experience.
It can be seen that in the present invention when storage system carries out asynchronous replication, storage system can start timer, and can week
The round-trip delay of the detection host duplication of phase property, under conditions of storage system normal work, round-trip delay is a very little
Value, when the hydraulic performance decline of storage system, the value of round-trip delay will increase therewith, in the detection cycle of asynchronous replication, such as
Fruit occurs that round-trip delay is excessive, then the cycle is considered as the bad cycle, and storage system can be to the bad cycle in the cycle more than 1/3
Number is counted, and when the counting of storage system reaches certain threshold value, storage system can close asynchronous replication automatically, and
Report IO overtime, so using this characteristic of asynchronous replication, can intuitively judge that the performance of storage system is in overload
State.

The present embodiment has made further instruction and optimization to technical scheme.It is as shown in Fig. 2 specific：
Step S21：Whether the asynchronous replication of detection storage system stops；
Step S22：If asynchronous replication does not stop, judge that storage system is in normal operating conditions；
Step S23：If asynchronous replication stops, whether detection storage system there is IO time-out；
Step S24：If storage system does not occur IO time-out, detect whether asynchronous replication stops again；
Step S25：If IO time-out occurs in storage system, judge that storage system is in overload.
It is understood that if the asynchronous replication normal operation of storage system, illustrates that storage system is in normal work
Make state, but if the asynchronous replication of storage system stops, then illustrate that the operation of storage system there is a problem.It is because asynchronous
Duplication is the process for another memory space that data are copied to storage system from a memory space of storage system, although
Temporal delay occurs during data backup, but generally, the time of this delay is a very little
Value, with the decline of performance of storage system, the time of delay can also increase, this usual time delay be by network bandwidth and
What the factors such as system load situation determined.In the detection cycle of asynchronous replication, if it exceeds when being come and gone in 1/3 cycle
Prolong excessive, then the cycle is considered as the bad cycle, and storage system can count to the number in bad cycle, when storage system
When counting reaches certain threshold value, storage system can close asynchronous replication automatically, and report IO overtime, and the present invention is exactly to utilize
This characteristic of asynchronous replication, intuitively judge that the performance of storage system is in overload, among prior art
Other method judge the performance of storage system, the method accuracy rate in the present invention is higher.
Further, whether stopped with 10S detection cycle detection asynchronous replication.
It is understood that detect whether asynchronous replication stops with 10S detection cycle, so not only live effect
It is good, and the real-time performance condition feedback of system to user interface can be improved Consumer's Experience.
In the present embodiment, before the process that whether asynchronous replication of above-mentioned detection storage system stops, in addition to step
S1 and step S2.
Step S1：Obtain the asynchronous replication instruction that user terminal is sent；
Step S2：Asynchronous replication instruction is responded.
It is understood that when this process of asynchronous replication is not present in storage system, sent by user first
Asynchronous replication instruction, instruction of the storage system to asynchronous replication is responded, then the performance of storage system is judged.
More specifically, the above-mentioned process responded to asynchronous replication instruction, including step S11 or step S12.
Step S11：By the data backup of the first volume in storage system into volume Two；
Wherein, the first volume is the volume created in advance in the local disk of storage system, and volume Two is in advance in this earth magnetism
The volume created in disk, and the first volume and volume Two is in the same size.
Step S12：By the data backup of the first volume in storage system into volume Two；
Wherein, the first volume is the volume created in advance in the local disk of storage system, and volume Two is in advance in storage system
The volume created in the shared disk of system, and the first volume and volume Two is in the same size.
It should be noted that during asynchronous replication, the position for creating volume can be the position in local disk
Put or shared disk in position, now, to be not limited thereto for the purpose of reaching practical application.
Accordingly, the invention also discloses a kind of performance of storage system decision-making system, as shown in figure 3, the system includes：
