Fig. 2 is the iSCSI data storage systems software system architecture block diagram of dual controller.
Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, a kind of iSCSI data-storage system of dual controller, including hardware platform and software platform, hardware
Platform includes that two master controllers, SAS hard disk, power supply and backboard, master controller are made of SAS controller, two master controllers
SAS controller same SAS hard disk is connected to by backboard, while building the heartbeat based on kilomega network between two controllers
Interconnection and the mirror-image channels netted based on 10,000,000,000；Software platform includes linux file system, SCST, MDADM, multi-path software.
By 2 tunnels 10,000,000,000 net caching mirror image synchronization between master controller, pass through 2 road kilomega network redundancy heartbeats, each master control
Device processed externally provides 2 tunnels 10,000,000,000 simultaneously and gigabit stores network interface；The SAS signal that master controller is supported according to SAS controller
Quantity externally supports multiple groups hard disk, while power supply has double- redundancy；Master controller is X86 platform processor.
As shown in Fig. 2, a kind of iSCSI data-storage system of dual controller, further include for realizing two controllers it
Between fault detection, synchronizing information, the application layer of failover and fault recovery, supporting layer, target drive layer, volume management layer
With hardware driving layer, application layer is equipped with basic MMU memory management unit；Supporting layer, which is equipped with, provides the service of basic service for application layer
Unit；Target drives layer to be equipped with for realizing the data transmission unit of storage device map to distance host；Volume management layer is set
The administrative unit that promising disk space provides；Layer is driven to be equipped with the driving unit to storage peripheral interface module；Basic storage tube
Reason unit includes SMI-S specification and web services software；Supporting layer includes that fault detection, synchronizing information, failover and failure are extensive
Multiple function；Administrative unit includes dynamic management and Redundancy Management function；Service unit is equipped with cache management and caching synchronizing function；
System further includes file system layer and block device layer.
Hardware platform is basis, and storage software systems are souls.Dual control software mainly pass through Raid function, fault detection,
Raid is synchronous, lun is synchronous, map information is synchronous, failover and fault recovery scheme are realized.Raid function is based on open source
SCST and MDADM software realization can support a variety of Raid modes, such as Raid0,1,5,6,10；Heartbeat is believed when fault detection
Number and the transmission of information and receive and use the same socket when fault recovery, handled by different types of data packet.Letter
Breath synchronization is transmitted by the communication mechanism that SMI-S standardized software provides；Raid is synchronous be mainly A controller in creation and
Need to be synchronized to B controller when deleting raid, in the raid of the end A creation, the end B is not required to re-create, but needs according to configuration text
Part activation could use.When raid is deleted at the end A, the end B needs to cut off raid and more new configuration file.Therefore when raid creation,
Need to transmit the raid configuration information, raid needs to transmit the raid title so as to opposite end deletion when deleting；A controller is creating
And need to be synchronized to B controller when deleting lun, in the lun of the end A creation, the end B is not required to re-create, but needs to restart
Raid could be used.The end A delete lun when, the end B does not need deduplication, but need to delete its mapping relations, restart raid into
Row updates；Map information synchronizing content includes that synchronous host information, host groups synchronizing information and lun map information are synchronous, such as right
Lun mapping, the synchronization of host, host group information, the operation that two side controllers are done are the same, therefore can be mentioned by SMI-S
The unified management interface of confession, respectively sends the corresponding command toward local and opposite terminal controller；When the controller fails, it needs
Failover is carried out, groundwork is right of attribution switching.It checks whether lun belongs to this controller, is looked into if belonging to this controller
See if there is session；It if there is session, remains unchanged, if whether inquiry opposite end has session without session；
If there is session in opposite end, local and the opposite end lun right of attribution are changed；After detecting heartbeat signal again, into fault recovery
Stage, fault recovery need synchronous raid, lun, mapping, scst configuration information.It is wherein the reliability for guaranteeing data transmission,
MD5 bit check information is added in data packet；By MAC mutual trust, detect whether current controller needs to send configuration file, if
It needs to carry out the new and old comparison of configuration file, simplifies process flow；Guarantee the dual controller configuration file time by time synchronization
Unification, to carry out the new and old comparison of file.
Data fault considers front-end and back-end, and front end is mainly controller failure, and rear end is mainly link failure, works as generation
When the failure of front end, by between controller pass through heartbeat can perceive opposite end whether failure, if can not receive the heartbeat of opposite end,
Startup separator transfer and the failover of service take-over work timing and adapter tube；If it is rear end failure, pass through multi-path software reality
Show data or business and be switched to another paths from a paths, data redundancy function also may be implemented, it is ensured that data are transmitted across
Data integrity in journey and storing process.
It should be noted that, in this document, relational terms such as first and second and the like are used merely to a reality
Body or operation are distinguished with another entity or operation, are deposited without necessarily requiring or implying between these entities or operation
In any actual relationship or order or sequence.Moreover, the terms "include", "comprise" or its any other variant are intended to
Non-exclusive inclusion, so that the process, method, article or equipment including a series of elements is not only wanted including those
Element, but also including other elements that are not explicitly listed, or further include for this process, method, article or equipment
Intrinsic element.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
