Specific embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by specific embodiment.
A kind of write request processing method is the embodiment of the invention provides, as shown in figure 1, may comprise steps of：
Step 101：In response to write request, the data that the write request asks write-in are obtained；
Step 102：The data of the caching request write-in；
In order that it is more rapid to cache speed, to reduce write delay, can by cache device cache it is described please
Seek the data of write-in.
That is, it is not that the network for directly writing data into rear end is deposited after the data that write-in is asked in capturing write request
In reservoir, but first by the cache device of data buffer storage to connection.
The cache device can be arranged on the network link of IP storages, specifically, can be near the network storage
Use end network on set up a speed buffering equipment, can be by the equipment with access link in the form of bypassing.
Step 103：Request is sent to the transmitting terminal of the write request to complete to instruct, and the request write-in that will be cached
In the network memory of data write-in rear end.
That is, the storage service request on link is listened to, when a write request is received, the number of Direct Acquisition write request
According to, and be stored in cache, and the reply of IO completions is write in forgery one, and the reply is sent to write request transmitting terminal, together
When be by data setting：Do not complete.After network memory only in rear end completes data write-in, and receive real rear end
The write request of return is successfully replied, then the data that will be cached are set to：Complete.
Specifically, during the transmitting terminal request to the write request completes instruction, the above method can also include：
The state of the data of the request write-in is set to not complete；Accordingly, write by the data of the request for caching write-in
After entering in the network memory of rear end, the above method can also include：Determine whether to receive the network storage of the rear end
The request that device is returned completes instruction；If received, the state of the data of the request write-in is set to complete.
The embodiment of the present invention additionally provides a kind of read request processing method, as shown in Fig. 2 may comprise steps of：
Step 201：In response to read request, determine whether be cached with the number that the read request asks to read in buffer memory device
According to；
In order that it is more rapid to cache speed, and to reduce read latency, can be data cached by cache device.
That is, it is not that the data to be read directly are obtained from the network memory of rear end when read request is received, but first in buffering
The data to be read are searched whether in equipment.
The cache device can be arranged on the network link of IP storages, specifically, can be near the network storage
Use end network on set up a speed buffering equipment, can be by the equipment with access link in the form of bypassing.
Step 202：If it has, then sending request to the transmitting terminal of the read request completes instruction, and the data that will be cached
Send to the transmitting terminal of the read request.
Further, whether the read request is cached with buffer memory device in response to read request, is determined to ask to read
Data after, can also include：If it is not, obtaining the number that the read request is asked from the network memory of rear end
According to；The data and request that will be obtained complete instruction, send to the transmitting terminal of the read request.
Above-mentioned write request processing method and read request processing method are illustrated with reference to a specific embodiment, but
It is worth noting that, the specific embodiment merely to the present invention is better described, does not constitute inappropriate limitation of the present invention.
The existing universal performance of the network storage is not high, and read-write delay is larger, to be written and read acceleration for the network storage.Under
Write request is accelerated respectively for face and read request accelerates explanation：
1) write request accelerates：
As shown in figure 3, can include：
S1：A speed buffering equipment is set up on the network near the use end of the network storage, and by the equipment with side
The form on road is linked into link.
S2：Buffer device intercepts the storage service request on link, when a write request is received, Direct Acquisition write request
Data, and write data into the cache of oneself.
S3：After the completion of caching, forge one and write the reply of IO completions, and this reply is sent to user, while will
The data setting for being cached is：Do not complete.
S4：If the write request for capturing real rear end return is successfully replied, the data that will be cached are set to：
Complete.
Above-mentioned buffer device can be connected in the network of user and service end using the mode of concatenation, this when
The role of agency is taken in storage, data cached when the I/O Request of user is received, and forges and replys, and I/O Request is turned
Back-end storage device is dealt into, is to have completed by data setting after the completion of back-end storage device.
2) read request accelerates：
As shown in figure 4, can include：
S1：A speed buffering equipment is placed on the network link of IP storages；
S2：The buffer device is linked into link with the equipment for bypassing, and eavesdrops the network message of all of IP storages
S3：If capture one read request, search it is locally buffered in whether have the data, have, forge one ask into
The reply of work(, and send data to request end.
That is, the acceleration of the network storage is realized by way of adding speed buffering equipment on storage link, so that plus
The IO performances of the fast network storage.
