Specific embodiment
Core of the invention is to provide transmission method, storage system and the computer-readable storage medium of IO between a kind of host
Matter, to reduce the resource overhead of host side, accelerates host and host for improving the transfer management of IO between host and host
Between I/O transfer.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The flow chart of Fig. 1 transmission method of IO between the first host provided in an embodiment of the present invention.As shown in Figure 1,
The transmission method of IO includes: between host
S10: the I/O transfer order of the first host transmission is received and parsed through, I/O transfer task is obtained.
In practical applications, storage system includes processor and memory, and scheme provided in an embodiment of the present invention can be with base
It is executed in the processor of storage system.Based on partitioning technique, storage system includes multiple storage units, i.e. logical volume LUN.
After receiving from the I/O transfer order that the first host is sent, parsing obtains I/O transfer task, including to be transmitted
Data, send address and receive address etc..
S11: it when I/O transfer task of the I/O transfer task between the first host and the second host, obtains and the first host
Corresponding first storage unit and the second storage unit corresponding with the second host.
S12: by storage I/O transfer task of the I/O transfer Task Switching between the first storage unit and the second storage unit.
In the prior art, the first host transmits data to the second host, needs first to deposit from the first host corresponding first
Storage unit called data, is sent to the second host, and the second host is stored in again in corresponding second storage unit.And actually
One storage unit and the second storage unit are likely to be in same storage system, therefore the processor based on storage system, are being obtained
Take and corresponding first storage unit of the first host and the second storage unit corresponding with the second host after, by the first host with
Storage I/O transfer task of the I/O transfer Task Switching between the first storage unit and the second storage unit between second host,
To be greatly saved transmission path, the data of transmission are without using the first host and the second host, to greatly save
The resource overhead of host.
S13: storage I/O transfer task is executed.
After storage system executes storage I/O transfer task, it can be sent to the first host or the second host and execute the anti-of completion
Feedback.
Further, storage I/O transfer task is executed, specifically:
Storage I/O transfer task is executed by the chronological order of generation.
The chronological order of storage system can be reached according to the I/O transfer task between the first host and the second host
Storage I/O transfer task is executed, the chronological order that storage I/O transfer task can also be generated according to conversion executes storage IO and passes
Defeated task can also execute storage I/O transfer task according to the priority level of preset storage I/O transfer task.
The transmission method of IO between host provided in an embodiment of the present invention is based on storage system, is receiving and parsing through first
The I/O transfer order that host is sent, after obtaining I/O transfer task, judges I/O transfer task between the first host and the second host
I/O transfer task when, obtain with corresponding first storage unit of the first host and the second storage corresponding with the second host singly
Member by storage I/O transfer task of the I/O transfer Task Switching between the first storage unit and the second storage unit, and is executed and is deposited
Store up I/O transfer task.Need data by the first storage unit, the first host, the second host and the second storage list from original
Member becomes to be no longer needed to directly to the second storage unit from the first storage unit by the first host or the second host, therefore to
Resource overhead is dramatically saved for one host and the second host, accelerates the I/O transfer between host and host.
The flow chart of Fig. 2 transmission method of IO between second of host provided in an embodiment of the present invention.As shown in Fig. 2,
On the basis of the above embodiments, in another embodiment, before step S13, the transmission method of IO between host further include:
S20: it receives and the transmission of storage I/O transfer task is arranged.
Correspondingly, step S13 executes storage I/O transfer task, specifically:
S21: storage I/O transfer task is executed by transmission setting.
In specific implementation, transmission setting is specifically as follows read-write number IOPS setting and/or bandwidth setting per second.
Further, can also include:
Transmission path according to storage I/O transfer task is storage I/O transfer task distribution transmission queue；
Wherein, transmission queue and transmission setting correspond.
For example, the first transmission queue pair can be set for partition holding D disk, E disk and F disk different in storage system
The transmission path between D disk and E disk is answered, the second transmission queue corresponds to the transmission path ... between E disk and F disk and receives user couple
The transmission setting of each transmission queue, and different transmission queue assignment worker threads is set as according to transmission.
The transmission method of IO between host provided in an embodiment of the present invention further includes on the basis of the above embodiments root
Storage I/O transfer task is executed according to the setting of user, further comprises being divided to the storage I/O transfer task of different transmission path
Different transmission queues, each transmission queue corresponds to different transmission settings, consequently facilitating according to the treatment situation pair of storage system
The adjustment that the execution of storage I/O transfer task is adapted to.
The flow chart of Fig. 3 transmission method of IO between the third host provided in an embodiment of the present invention.As shown in figure 3,
On the basis of the above embodiments, in another embodiment, between host IO transmission method further include:
S30: the I/O latency time is calculated according to the quantity of storage I/O transfer task.
When storage I/O transfer task is more, it is likely to result in storage system congestion, longer storage I/O transfer is waited to appoint
Business can be forced to interrupt.
In specific implementation, the line that can be occupied according to the quantity or each storage I/O transfer task of storage I/O transfer task
Number of passes calculates the I/O latency time.
S31: the I/O latency time is sent to the first host.
The I/O latency time is sent to the first host, so that the first host assigns the transmission life to storage I/O transfer task
It enables, such as execution of the pause to storage I/O transfer task avoids storage I/O transfer task from interrupting because the waiting time is too long.
Further, can also include:
S32: when the I/O latency time being greater than preset value, suspend the execution to storage I/O transfer task.
Step S32 can be performed simultaneously with step S31.
Storage system can also voluntarily judge the relationship of I/O latency time and preset value, be greater than preset value when the I/O latency time
When, suspend the execution to storage I/O transfer task, prevents storage I/O transfer task from interrupting because the waiting time is too long.
The transmission method of IO between host provided in an embodiment of the present invention further includes on the basis of the above embodiments root
The I/O latency time is calculated according to the quantity of storage I/O transfer task, the I/O latency time is sent to the first host or in I/O latency
Between be greater than preset value when pause to storage I/O transfer task execution, avoid storage I/O transfer task due to the waiting time is too long in
It is disconnected.
The corresponding each embodiment of transmission method of IO between host as detailed above, on this basis, the present invention also public affairs
Storage system corresponding with the above method is opened.
