With the development of big data, transmission range is limited between by disk array memory capacity and disk and master control, is passed The disc array system of system cannot meet application demand gradually, and the demand of storage device networking is come into being.Such as Fig. 2 The shown disc array system Organization Chart based on exchange network, HBA sides pass through exchange network and disk frame (Just a Bunch Of Disks, JBOD) connection, wherein, the exchange network for telecommunication network component (telecommunication network further include access net and Transmission network), exchange network may include Circuit Switching Network, message switching network, the packet switching network, in embodiments of the present invention, the friendship Switching network can be specifically Ethernet (Ethernet) etc., and each HBA sides include HBA, master control and upper layer software (applications) in exchange network, Several disks are hung under each disk frame and form a disk array, disk array can be SAS disk arrays or PCIE disk arrays etc., several HBA are in several JBOD equalitys in exchange network, i.e. disk under HBA and JBOD Array does not have specific attaching relation, and forming one theoretically can be with the storage system of infinite expanding.The embodiment of the present invention is exactly It to complete disk discovery procedure of each master control to each disk in each JBOD in such a system, perform the disk The main body of discovery procedure can be the HBA cards in master control.

Referring to Fig. 3, the stream of method is found for a kind of disk array based on exchange network provided in an embodiment of the present invention Cheng Tu, HBA are connected at least one disk frame by the exchange network, and the disk in the disk frame forms the disk battle array Row, this method comprise the following steps：

Step S101, HBA broadcast the first heartbeat broadcast packet by exchange network, and the first heartbeat broadcast packet includes described The exchange network address of HBA.

In the present embodiment, in disc array system framework as shown in Figure 2, the one side of exchange network includes one or more HBA, opposite side then include one or more disk frames.It after each HBA is connected to exchange network, is powered on, completes initialization, HBA obtains the exchange network address of itself, such as in ethernet networks, HBA obtains the MAC Address of itself, the exchange network address Can also other similar with unique lock or the information of HBA can be found.HBA broadcasts heartbeat broadcast packet, which does not have Specific target object, HBA and disk frame in the exchange network can receive the broadcast packet, which includes The exchange network address of HBA, after only other HBA receive the broadcast packet of the HBA, by the class for identifying the heartbeat broadcast packet Type will not carry out heartbeat response.

Step S102, the HBA receive the first heartbeat response bag that at least one disk frame is sent, and first heartbeat is rung It should include the disk array information of at least one disk frame, obtain the disk array letter of at least one disk frame Breath；Wherein, the disk array information of the disk frame includes the exchange network address of the disk frame.

Multiple HBA in Fig. 2 are connected by exchange network with multiple disk frames, and one or more magnetic are hung under disk frame Disk, the one or more disk form disk array, disk frame may also without connecting any disk, this multiple HBA with it is multiple Disk frame equality is in exchange network, i.e. HBA does not have specific attaching relation with the disk array under disk frame.Switching network After any one disk frame in network receives the heartbeat broadcast packet of HBA, heartbeat response can be carried out, according to the exchange network of HBA Address sends heartbeat response bag to HBA.The heartbeat response bag includes the disk array information of the disk frame, the magnetic of the disk frame Disk array information includes the exchange network address of the disk frame, for example, by taking Ethernet as an example, the exchange network address of disk frame is The MAC Address of disk frame, the exchange network address can also other similar with unique lock or can find the letter of disk frame Breath.HBA broadcasts heartbeat broadcast packet by all devices into exchange network, and the disk frame of exchange network opposite side can connect The heartbeat broadcast packet is received, thus heartbeat broadcast packet is responded, the heartbeat response bag that then HBA reception of magnetic disc frame is sent, The disk array information of the disk frame of exchange network opposite side can be obtained, so as to complete the discovery procedure of disk array

As it can be seen that a kind of disk array based on exchange network provided according to embodiments of the present invention finds method, HBA passes through Broadcast heartbeat broadcast packet so that the heartbeat broadcast packet of HBA broadcast is being received by the disk frame that exchange network is connected with HBA Afterwards, heartbeat response bag is sent to host bus adaptor, and heartbeat response bag includes the disk array information of disk frame, so as to letter The disk array discovery procedure based on exchange network is singly effectively completed.

Referring to Fig. 4, find method for another disk array based on exchange network provided in an embodiment of the present invention Flow chart, HBA and at least one disk frame are connected by the exchange network, and the disk in the disk frame forms the disk Array, this method comprise the following steps：

Step S201, HBA broadcast the first heartbeat broadcast packet by exchange network, and the first heartbeat broadcast packet includes described The exchange network address of HBA.

Step S202, the HBA receive the first heartbeat response bag that at least one disk frame is sent, and first heartbeat is rung It should include the disk array information of at least one disk frame, obtain the disk array letter of at least one disk frame Breath；Wherein, the disk array information of the disk frame is included in the exchange network address and the disk frame of the disk frame The home address of disk.

Step S201 and step S202 is identical with the step S101 and step S102 difference of embodiment illustrated in fig. 3, herein not It repeats again.

It should be noted that in the present embodiment, heartbeat broadcast packet and heartbeat response bag are the agreement according to exchange network The privately owned message of definition.The embodiment of the present invention does not include specific privately owned message definition, but needed in message it is special comprising some Field or content.For example, exchange network is Ethernet；Then the first heartbeat broadcast packet and the first heartbeat response bag are Ethernet Message.

In the present embodiment, the home address of the disk in disk frame is further included in the disk array information of the disk frame, For example, lower hang is SAS disks in disk frame, the home address of the disk in the disk frame refers to SAS Address, this Address is that disk is good once producing configuration, and each disk is different, and user is not required subsequently to set.When So, one or more disks, the disk number or zero of lower extension, if the disk number of lower extension can be hung in disk frame down It is zero, then the home address of the disk in the disk frame is sky.

The exchange network address of at least one disk frame is recorded in disk array information by step S203, the HBA In table.

Step S204, the HBA are using the exchange network address of at least one disk frame as index, by least one institute The home address for stating the disk in disk frame is recorded in the disk array information table.

After the heartbeat response bag that the disk frame in exchange network is sent is received in step S202, heartbeat response bag is extracted In disk frame exchange network address and disk frame in disk home address, the disk array letter being recorded in inside HBA It ceases in table, as shown in table 1.

1 disk array information table of table

During disk array information table is established, first, the exchange network address of each disk frame is recorded in magnetic In disk array information table, in table 1, the first row that the exchange network address mac0-macN of disk frame is respectively written into table 1, Then, due to that may have the home address of multiple disks under each disk frame, with the exchange network address of each disk frame For index, the home address of each disk in the disk frame is recorded in the disk array information table, until completing all The record of the home address of disk, so as to form such a complete disk array information table of table 1, so as to the friendship of disk frame Switching network address is index so that by the exchange network address of disk frame, can find the disk array information of the disk frame. It should be noted that the home address of each disk in the exchange network address of recording disc frame and disk frame can also not have Sequencing can record simultaneously.

Such a disk array information table is established in HBA, in subsequent operation, HBA can be according to the disk array The a certain disk that information table is given in a certain disk frame sends specific task dispatching.

Step S205, the HBA broadcast the second heartbeat broadcast packet, the second heartbeat broadcast packet by the exchange network Exchange network address including the HBA.

Step S206, the HBA receive the second heartbeat response bag that at least one disk frame is sent, second heart Jumping response bag includes the disk array information of the disk frame.

Since HBA is periodic broadcast heartbeat broadcast packet, so HBA is broadcasting heartbeat broadcast packet and is completing to exchange for the first time After the discovery procedure of disk array in network, broadcast heartbeat broadcast packet is also may proceed to, and continues to disk frame transmission Heartbeat response bag, the heartbeat broadcast packet broadcasted every time still can carry the exchange network address of HBA, and heartbeat response bag still can wrap Include the disk array information of disk frame.Herein, " first " and " second " in the first and second heartbeat broadcast/response bag is Show the temporal priority of broadcast/reception, there is no other particular meanings, the form of heartbeat broadcast/response bag etc. or phases With.Certainly, new disk frame may be extended in exchange network, hot plug may also can occur for the disk in original disk frame Or heat addition, therefore, the content of each heartbeat response bag may be different, exactly because as such, it is desirable to disk to foundation Array information table is updated.

Step S207, the HBA believe the disk array of the disk frame in the second heartbeat response bag of the reception Breath is compared with the information recorded in the disk array information table.

Whether HBA determines to have in exchange network the disk array of disk frame to believe according to the second heartbeat response bag received Breath updates, specifically by the disk array information and disk array information of the disk frame in the second heartbeat response bag of reception The information recorded in table is compared, if the disk array information for having disk frame in exchange network updates, HBA according to The the second heartbeat response bag received, the disk array information of the disk frame to being recorded in disk array information table carry out more Newly.It is specific relatively as follows with renewal process：

Step S208, if in not recording the second heartbeat response bag of the reception in the disk array information table Disk frame disk array information, then the HBA determine the disk array information for having disk frame in the exchange network Update.

Step S209, the HBA believe the disk array of the disk frame in the second heartbeat response bag of the reception Breath is recorded in the disk array information table.

After the discovery procedure of disk array is completed, new disk frame may be extended in exchange network, by that will receive The second heartbeat response bag in disk frame disk array information compared with the information recorded in disk array information table, If do not have completely there are the disk array information of the disk frame in Unrecorded second heartbeat response bag in disk array information table There is record, be the new disk frame of extension, it is determined that the disk array information for having disk frame in exchange network updates, will The disk array information is recorded in disk array information table, and the information of record is with including the exchange network of the disk frame of the extension The home address of disk in location and disk frame.

Step S210, if had recorded in the disk array information table in the second heartbeat response bag of the reception Disk frame exchange network address, but in the second heartbeat response bag of the reception in the disk array information table Disk frame exchange network address for index corresponding record disk frame in disk home address, the institute with the reception State that the home address of the disk in the disk frame in the second heartbeat response bag is inconsistent, then the HBA determines the exchange network In have disk frame disk array information update.

The disk of step S211, the HBA in the disk frame in the second heartbeat response bag of the reception Home address using the exchange network address of the disk frame in the second heartbeat response bag as index, updates the disk array The home address of disk in the disk frame recorded in information table.

After the discovery procedure of disk array is completed, disk in original disk frame it is possible that can be added or be removed, HBA periodically sends heartbeat broadcast packet, and HBA is believed by the disk array of the disk frame in the second heartbeat response bag that will receive Breath is compared with the information recorded in disk array information table, if having recorded second heart of reception in disk array information table The exchange network address of the disk frame in response bag is jumped, but in the second heartbeat response bag of reception in disk array information table The exchange network address of disk frame for index corresponding record disk frame in disk home address, described second with reception The home address of the disk in disk frame in heartbeat response bag is inconsistent, then HBA determines there is disk frame in the exchange network Disk array information update, disks of the HBA in the disk frame in the second heartbeat response bag of the reception Home address, using the exchange network address of the disk frame in the second heartbeat response bag as index, update disk array information table The home address of disk in the disk frame of middle record.

After step S212, the HBA periodically broadcast the second heartbeat broadcast packet by the exchange network, according to The the second heartbeat response bag received determines whether that exchange network chain rupture occurs for disk frame.

Step S213, if there is exchange network chain rupture occurs for disk frame, then the HBA deletes the disk array information table The disk array information of the disk frame of the generation exchange network chain rupture of middle record.

Disk frame is also required to be updated disk array information table there is a situation where exchange network chain rupture, i.e.,：The HBA cycles Property broadcast heartbeat broadcast packet, every time broadcast heartbeat broadcast packet when, the disk frame in disk array information table can be swapped Network chain rupture detects, and detects a certain disk frame chain rupture, relevant entries is just deleted, so as to update the disk array in time Information table.Wherein, chain rupture detection mode is flexible, such as sets chain rupture and detect number as m, when certain heartbeat broadcast packet is not received It to the heartbeat response of the JBOD frames of mac0, is denoted as 1 time, the continuous m times heartbeat response for not receiving mac0 is treated as JBOD frames hair Exchange network chain rupture event is given birth to.

As it can be seen that a kind of disk array based on exchange network provided according to embodiments of the present invention finds method, HBA passes through Broadcast heartbeat broadcast packet so that the heartbeat broadcast packet of HBA broadcast is being received by the disk frame that exchange network is connected with HBA Afterwards, heartbeat response bag is sent to host bus adaptor, and heartbeat response bag includes the disk array information of disk frame, so as to letter The disk array discovery procedure based on exchange network is singly effectively completed；And by establishing and safeguarding disk array information table, HBA can obtain the newer disk array information of disk frame in real time.

Referring to Fig. 5, find method for another disk array based on exchange network provided in an embodiment of the present invention Flow chart, HBA and disk frame are connected by the exchange network, and the disk in the disk frame forms the disk array, should Method comprises the following steps：

Step S301, disk frame receive the heartbeat broadcast packet that HBA is broadcasted by exchange network, and the heartbeat broadcast packet includes The exchange network address of the HBA.

In the present embodiment, in disc array system framework as shown in Figure 2, the one side of exchange network includes one or more HBA, opposite side then include one or more disk frames.It after each disk frame is connected to exchange network, is powered on, is completed initial Change, process decoupling, here, process decoupling refer to disk frame during initialization, the process that disk frame is initialized at oneself In a series of similar operation shaken hands on some that be done of disk initialization SAS protocols is completed with disk.
