Embodiment

A kind of method flow diagram for network dividing domain that Fig. 1 provides for the embodiment of the present invention.As shown in Figure 1, the method for the present embodiment comprises:

Step 101, reception Login Register message, described Login Register message comprises the device type information of the first equipment sending described Login Register message.

If according to the device type information in described Login Register message, step 102 determines that the first equipment is server, be that the first equipment creates a server domain, first equipment is added in created server domain, and the RSCN message that the first device logs produces is sent to memory devices all in memory device territory.

If have memory device and the first equipment to connect in step 103 memory device territory and the first equipment can use the described memory device connected with the first equipment, the described memory device connected with the first equipment is moved in the server domain at the first equipment place from memory device territory, and record the first equipment, mapping relations between memory device that described and the first equipment connects and the first equipment place server domain three.

The executive agent of the present embodiment method can be the switch in FC network.Described switch can be switch (referred to as direct-connected switch) direct-connected with the first equipment in FC network, also can be positioned at the first equipment in FC network communication path on and by other switches (referred to as indirectly connected switch) of direct-connected switch and the first equipment connection.

Concerning direct-connected switch, the process receiving Login Register message is the Login Register message directly receiving the first equipment transmission.Concerning indirectly connected switch, the process receiving Login Register message is receive the Login Register message forwarded by direct-connected switch.Concrete, when first device request logs in FC network, Login Register message can be sent to its direct-connected switch, first equipment is by the address designation (FCID) of this Login Register message application FC network, and can by the device type of self, be such as server or memory device, and the FC parameter etc. that self supports is registered on direct-connected switch.The Login Register message of the first equipment is added in name server (NameServer) by direct-connected exchange opportunity, and to this name server synchronous of other switches in FC network.Name server can be an information list on direct-connected switch.

After switch receives Login Register message, be not send directly to servers all in FC network and memory device the RSCN message produced because of the login of the first equipment as prior art, but therefrom obtain the device type information of the first equipment, the device type of the first equipment is then determined according to this device type information.

If switch determines that the first equipment is server, switch is that the first equipment creates a server domain, first equipment is joined in created server domain, and the RSCN message that the first device logs produces is sent to memory devices all in memory device territory.

In the present embodiment, according to the type of the equipment of access FC network, for FC network divides the territory of two types, one is memory device territory, and one is server domain.Wherein, memory device territory presets, first the memory device of all FC of adding networks is added in memory device territory, when moving in the server domain at the server place connected with this memory device from memory device territory after memory device and certain server connect, further, if the server connected with this memory device can use this memory device, then this memory device just really moves in this server place server domain, if the server connected with this memory device cannot use this memory device, then this memory device also can be moved back in memory device territory from this server place server domain.Each server domain comprises a server, i.e. the corresponding server domain of each server.Concrete, when each server log FC network, switch creates a server domain for this server, and is added created server domain.

Illustrate at this, " territory " that relate in various embodiments of the present invention is not physically real region, but a kind of notional territory; Accordingly, " migration " that relate in various embodiments of the present invention is not real memory device is moved to another place from a place, just switch is carrying out in the partition process of territory to FC network, describe the one of transition state, described " migration " mainly refers to can from a notional domain migration to another notional territory.

Consider in FC network, generally do not need to carry out FC communication between server, a memory device is only distributed to a station server and is used, and a station server can use multiple stage memory device simultaneously.Therefore, when the first equipment is server, switch is for the first equipment establishment server domain and after the first equipment is added created server domain, the RSCN message that the first device logs produces is sent to memory devices all in memory device territory by switch.

Illustrate at this, if the switch of the executive agent as the present embodiment method, be not directly be connected with the memory device in memory device territory, then by other switches, RSCN message can be sent to corresponding memory device.If other places do not have specified otherwise, described switch all refers to the switch of the executive agent as the present embodiment method.

After memory device in memory device territory receives RSCN message, can attempt connecting with the first equipment.Concrete, memory device in memory device territory can log in (PortLogin by switch to the first equipment transmit port, referred to as PLOGI) message, if the refuse information that first equipment that receives in default time of reception returns, then memory device and the first equipment connect unsuccessfully; If do not receive the refuse information that the first equipment returns in default time of reception, then memory device and the first equipment connect successfully.Specifically can carry out timing by timer to the time of reception preset.Whether switch by the process connected between the memory device in monitoring memory device territory and the first equipment, can be determined in memory device territory and has memory device and the first equipment to connect.Optionally, switch can preset the timer for connection establishment process, if after timer timing terminates, also do not hear the refuse information that the first equipment sends, then determine have memory device and the first equipment to connect in memory device territory.

Further, the information of available server that every platform memory device is all pre-configured, after memory device in memory device territory and the first equipment connect, first equipment also can determine whether to use the memory device connected with the first equipment, namely determines whether the memory device connected with the first equipment can be used; If determination result is yes, then the first equipment can keep the connection between itself and this memory device, if determination result is no, the first equipment can remove the connection between itself and this memory device.Concrete, the first equipment publishes (PortLogout, referred to as PLOGO) message by switch to the memory device transmit port connected with it, to remove the connection between itself and this memory device.Switch by the connection demolishing process in monitoring first equipment and memory device territory and between the memory device that connects of the first equipment, can determine whether the first equipment can use the memory device in the memory device territory connected with the first equipment.Optionally, switch can preset the timer for connecting demolishing process, if after timer timing terminates, also do not hear the PLOGO message that the first equipment sends, then determine that the first equipment can use the memory device connected with the first equipment in memory device territory; Otherwise, if before timer timing terminates, listen to the PLOGO message that the first equipment sends, then determine that the first equipment cannot use the memory device connected with the first equipment in memory device territory.

Based on above-mentioned, if switch determines in memory device territory have memory device and the first equipment to connect and the first equipment can use the described memory device connected with the first equipment, the described memory device connected with the first equipment is moved in the server domain at the first equipment place from memory device territory, and record the first equipment, mapping relations between memory device that described and the first equipment connects and the first equipment place server domain three.

If determine in memory device territory and do not have memory device and the first equipment to connect, or determining in memory device territory has memory device and the first equipment to connect but the first equipment cannot use the described memory device connected with the first equipment, then record the first equipment and the first equipment place server domain mapping relations between the two.

So far, switch is when the first equipment is server, first equipment and needs have been divided in same territory with the memory device of the first devices communicating, the RSCN message that equipment in this territory follow-up like this changes and produces only need be noticed in this domain, the server in other territories or memory device can not be advertised to, reduce the coverage that equipment changing causes, decrease the network resources waste that unnecessary announcement process causes, be conducive to the stability and the availability that improve network.In addition, due to the method for network dividing domain that the present embodiment method provides, do not need the participation of keeper, automatically completed by the switch in FC network, have and realize flexibly, the more high advantage of efficiency.

If above-mentioned switch determines in memory device territory have memory device and the first equipment to connect and the first equipment can use the described memory device connected with the first equipment, the described memory device connected with the first equipment is moved in the server domain at the first equipment place from memory device territory, and record the first equipment, a kind of execution mode of mapping relations between memory device that described and the first equipment connects and the first equipment place server domain three comprises:

First, determine in memory device territory, whether have memory device and the first equipment to connect; If determine in memory device territory and have memory device and the first equipment to connect, the described memory device connected with the first equipment is moved in the first equipment place server domain from memory device territory;

Then, determine whether the first equipment can use the described memory device connected with the first equipment; If the first equipment of determining can use the described memory device connected with the first equipment, then record the first equipment, mapping relations between memory device that described and the first equipment connects and the first equipment place server domain three.

Based on above-mentioned execution mode, if have memory device and the first equipment to connect in memory device territory but the first equipment cannot use the described memory device connected with the first equipment, described method also comprises: moved in memory device territory from the first equipment place server domain by the described memory device connected with the first equipment.

If above-mentioned switch determines in memory device territory have memory device and the first equipment to connect and the first equipment can use the described memory device connected with the first equipment, the described memory device connected with the first equipment is moved in the server domain at the first equipment place from memory device territory, and record the first equipment, the another kind of execution mode of mapping relations between memory device that described and the first equipment connects and the first equipment place server domain three comprises:

First, determine in memory device territory, whether have memory device and the first equipment to connect; If determine in memory device territory and have memory device and the first equipment to connect, then determine whether the first equipment can use the described memory device connected with the first equipment; If the first equipment of determining can use the described memory device connected with the first equipment, the described memory device connected with the first equipment is moved in the first equipment place server domain from memory device territory, and record the first equipment, mapping relations between memory device that described and the first equipment connects and the first equipment place server domain three.

In this explanation, mapping relations between the memory device that the present embodiment connects to switch record first equipment and the first equipment and the first equipment place server domain three, and the specific implementation of switch record first equipment and the first equipment place server domain mapping relations does not between the two limit.

Such as, switch can with the above-mentioned mapping relations of mode record of list item, every bar list item at least comprises following information: the port numbers (FC-Port) that equipment is connected with switch, device type, the FCID of equipment, the global unique identification (WorldWideNumber of equipment, referred to as WWN), global unique port mark (WorldWidePortNumber, referred to as WWPN) of equipment and the mark (ID) in territory, equipment place.Wherein, the WWN whole world of equipment is unique, is the NIC address mark of 64; The WWPN whole world of equipment is unique, and be also the NIC address mark of 64, this NIC address identifies the concrete port that can be identified on network interface card, network interface card has a port at least.In this embodiment, each territory is distinguished by its ID, such as, can be the ID arranging memory device territory be 1, and the ID of other server domain increases progressively successively from 2, but is not limited thereto, and every mode that can distinguish each territory can.

Based on above-mentioned, mapping relations between the memory device that switch record first equipment and the first equipment connect and the first equipment place server domain three can adopt two list items, for the ID of the first equipment place server domain for 2, then recorded mapping relations can be as shown in table 1.

As can be seen from Table 1, memory device and the first equipment in same territory, namely in the first equipment place server domain.

Fig. 2 for another kind that the embodiment of the present invention provides be the method flow diagram of network dividing domain.As shown in Figure 2, the method for the present embodiment comprises:

Step 201, reception Login Register message, described Login Register message comprises the device type information of the first equipment sending described Login Register message.

If according to the device type information in described Login Register message, step 202 determines that the first equipment is memory device, first equipment is added in memory device territory, and the server RSCN message that the first device logs produces is sent in Servers-all territory and memory device, wherein each server domain comprises a server.

If have server and the first equipment to connect in step 203 Servers-all territory and the described server connected with the first equipment can use the first equipment, first equipment is moved to from memory device territory in the server domain at the described server place connected with the first equipment, and record the first equipment, mapping relations between server that described and the first equipment connects and the server place server domain three that described and the first equipment connects.

Concerning direct-connected switch, the process receiving Login Register message is the Login Register message directly receiving the first equipment transmission.Concerning indirectly connected switch, the process receiving Login Register message is receive the Login Register message forwarded by direct-connected switch.Concrete, when first device request logs in FC network, Login Register message can be sent to its direct-connected switch, first equipment is by the address designation (FCID) of this Login Register message application FC network, and can by the device type of self, be such as server or memory device, and the FC parameter etc. that self supports is registered on direct-connected switch.The Login Register message of the first equipment is added in name server (NaneServer) by direct-connected exchange opportunity, and to this name server synchronous of other switches in FC network.Name server can be an information list on direct-connected switch.

If switch determines that the first equipment is memory device, the first equipment adds in memory device territory by switch, and the RSCN message that the first device logs produces is sent to the server in Servers-all territory.In the present embodiment, according to the type of the equipment of access FC network, for FC network divides the territory of two types, one is memory device territory (ShareZone), and one is server domain.Wherein, memory device territory presets, first the memory device of all FC of adding networks is added in memory device territory, moves in the server domain at the server place using this memory device when memory device is used by certain server from memory device territory again.Each server domain comprises a server, i.e. the corresponding server domain of each server.Concrete, when each server log FC network, switch creates a server domain for this server, and is added created server domain.

Consider in FC network, generally do not need to carry out FC communication between memory device, a memory device is only distributed to a station server and is used, and a station server can use multiple stage memory device simultaneously.Therefore, when the first equipment is memory device, after first equipment joins in memory device territory by switch, also the RSCN message that the first device logs produces can be sent to the server in Servers-all territory and memory device, namely only send RSCN message to all devices in each server domain.
