Abstract

Claims (85)

1 . A storage apparatus comprising:

a storage device comprising an access queue and configured to:

receive, using the access queue, access requests of clients, wherein the clients comprise a first client, and wherein the access requests comprise a first access request corresponding to the first client;

execute the first access request to obtain a processing result; and

return the processing result; and

a network device configured to:

receive the access requests from the clients;

connect the storage device to the clients;

allocate local identifiers to client identifiers carried in the access requests, wherein the local identifiers uniquely identify the clients;

replace the client identifiers carried in the access requests with the local identifiers;

send the access requests comprising the local identifiers to the access queue;

receive the processing result from the storage device;

return the processing result to the first client; and

record a mapping relationship between the client identifiers and the local identifiers using a table,

wherein the table is a hash table,

wherein in the hash table a keyword of an application server is at least one of the local identifiers, and

wherein a value of the application server is at least one of the client identifiers.

2 . The storage apparatus of claim 1 , wherein the network device is further configured to:

store a correspondence between the access queue and information about the clients; and

further send the access requests based on the correspondence.

3 . The storage apparatus of claim 2 , wherein the information is connection information from when the network device establishes connections to the clients, and wherein the network device is further configured to:

determine, when receiving the access requests, the access queue based on the connection information; and

send the connection information to the access queue.

4 . The storage apparatus of claim 2 , wherein the information is connection information from when the network device establishes connections to the clients.

5 . The storage apparatus of claim 3 , wherein the network device is further configured to establish remote direct memory access (RDMA) connections with the clients.

6 . A method implemented by a network device and comprising:

receiving access requests from clients, wherein the clients comprise a first client, and wherein the access requests comprise a first access request corresponding to the first client;

connecting a storage device to the clients;

allocating local identifiers to client identifiers carried in the access requests, wherein the local identifiers uniquely identify the clients;

replacing the client identifiers carried in the access requests with the local identifiers;

sending the access requests comprising the local identifiers to an access queue of the storage device;

receiving, from the storage device, a processing result that is based on execution of the first access request;

returning the processing result to the first client; and

recording a mapping relationship between the client identifiers and the local identifiers using a table,

wherein the table is a hash table,

wherein in the hash table a keyword of an application server is at least one of the local identifiers, and

wherein a value of the application server is at least one of the client identifiers.

7 . The method of claim 6 , further comprising:

storing a correspondence between the access queue and information about the clients; and

further sending the access requests based on the correspondence.

8 . The method of claim 7 , wherein the information is connection information from when the network device establishes connections to the clients, and wherein the method further comprises:

determining, when receiving the access requests, the access queue based on connection information; and

sending the connection information to the access queue.

9 . The method of claim 7 , wherein the information is connection information from when the network device establishes connections to the clients.

10 . The method of claim 8 , further comprising establishing remote direct memory access (RDMA) connections with the clients, and wherein the connection information is a queue pair (QP) from when the network device establishes the RDMA connections.

11 . A network device comprising:

a memory configured to store instructions; and

one or more processors coupled to the memory and configured to execute the instructions to cause the network device to:

receive access requests from clients, wherein the clients comprise a first client, and wherein the access requests comprise a first access request corresponding to the first client;

connect a storage device to the clients;

allocate local identifiers to client identifiers carried in the access requests, wherein the local identifiers uniquely identify the clients;

replace the client identifiers carried in the access requests with the local identifiers;

send the access requests comprising the local identifiers to an access queue of the storage device;

receive, from the storage device, a processing result that is based on the first access request;

return the processing result to the first client; and

record a mapping relationship between the client identifiers and the local identifiers using a table,

wherein the table is a hash table,

wherein in the hash table a keyword of an application server is at least one of the local identifiers, and

wherein a value of the application server is at least one of the client identifiers.

12 . The network device of claim 11 , wherein the one or more processors are further configured to execute the instructions to cause the network device to:

store a correspondence between the access queue and information about the clients; and

further send the access requests based on the correspondence.

13 . The network device of claim 12 , wherein the information is connection information from when the network device establishes connections to the clients, and wherein the one or more processors are further configured to execute the instructions to cause the network device to:

determine, when receiving the access requests, the access queue based on connection information; and

sending the connection information to the access queue.

14 . The network device of claim 12 , wherein the information is connection information from when the network device establishes connections to the clients.

15 . The network device of claim 13 , wherein the one or more processors are further configured to execute the instructions to cause the network device to establish remote direct memory access (RDMA) connections with the clients.

16 . The network device of claim 15 , wherein the connection information is a queue pair (QP) from when the network device establishes the RDMA connections.

17 . The network device of claim 13 , wherein the one or more processors are further configured to execute the instructions to cause the network device to determine, based on the connection information, the first client.

18 . The network device of claim 14 , wherein the one or more processors are further configured to execute the instructions to cause the network device to:

obtain a first local identifier of the local identifiers and from the processing result;

determine, based on the first local identifier, first connection information corresponding to the first client; and

further return the processing result to the first client based on the first connection information.

19 . The storage apparatus of claim 3 , wherein the network device is further configured to determine, based on the connection information, the first client.

20 . The storage apparatus of claim 19 , wherein the storage device is further configured to return the connection information to the network device when returning the processing result.

21 . The storage apparatus of claim 4 , wherein the network device is further configured to:

obtain a first local identifier of the local identifiers and from the processing result;

determine, based on the first local identifier, first connection information corresponding to the first client; and

further return the processing result to the first client based on the first connection information.

22 . The storage apparatus of claim 5 , wherein the connection information is a queue pair (QP) from when the network device establishes the RDMA connections.

23 . The method of claim 8 , further comprising determining, based on the connection information, the first client.

24 . The method of claim 9 , further comprising:

obtaining a first local identifier of the local identifiers and from the processing result;

determining, based on the first local identifier, first connection information corresponding to the first client; and

further returning the processing result to the first client based on the first connection information.
