Embodiment
General principle of design of the present invention is: centralized decision, distributed treatment.Layout strategy of the present invention mainly comprises: on system architecture, select private server mode process metadata; On data access, select direct access mode; To the mapping of system server, select dynamic single mapping mode at file; On data consistency, select File contract mode.
Compare with serverless backup mode (Serverless mode), it is more clear to adopt private server (group) mode system architecture and function to divide; During the storage system upgrading, need not the upgrade application server; The good confidentiality of data; Storage system is easy to control, manage and optimize and is not subjected to the influence of application server; In addition, has favorable expansibility equally.
Immediate data visit is meant that memory device directly links on the network, and server directly carries out the accessing operation of data to equipment by network; Indirect data access is meant by file server and visits data.Obviously, the immediate data access mode is more fast, thereby can improve the performance of system.
The mapping of file and system server comprises dual mode: single mapping and multidimensional mapping.Single mapping is meant that at any time a file can only be mapped to a system server at most.Compare with the multidimensional mapping, single mapping realizes more simple, simplied system structure design greatly; Dirigibility is better, is easy to provide the service that storage waits restriction of sharing; The consistency problem of great reduced data is because each file only is responsible for by a system server.File is locked or contract when operation when need, these operations all are only limited to relevant some servers, rather than distributed operation.In addition, single mapping can well realize the fairness of shining upon and the logicality of mapping.
The consistance of data comprises the consistance of metadata and the consistance of file data.The metadata here not only comprises the metadata in the file system, and comprises dynamic structure associated with the file, as file lock, contract etc.These data structures are complete in system, consistent, confirmability all has decisive influence for complexity, operational efficiency and the rejuvenation of system fast.Employing file contract mode realizes the consistance of file data, has reduced the complexity of system design and realization.
The operation of file can be divided into two big classes: metadata operation class and data manipulation class.Main metadata operation takies 50% system resource approximately, and the data write operation takies 50% system resource approximately.Consider from the storage system angle, not only will provide fast data transmission, and disposal system metadata effectively.The extensibility that metadata is handled is the key of total system extensibility.
In the middle of these are selected, dynamically the selection of single mapping mode is very important: adopt single mapping, the distribution of file between system server just become a complete disjoint division, simplified the design of system architecture, adopt dynamically mapping, load that can the dynamic adjusting system server, the optimization system utilization of resources, thus improve the dynamic process ability of system.
Fig. 2 has described the overall logic structure of the new services device system of storage Network Based and expandable system structure, as can be seen, present invention includes a plurality of application servers 1, a plurality of metamessage server 2, one or more load balance server 3, the network storage equipment 6 and these nodes are coupled together interconnection exchange network 4.
The present invention adopts novel server system structure---distributed network expandable system structure, all server is all distributed with the network storage equipment and be connected by the interconnection exchange network in the system, all servers all pass through exchange network accesses network memory device, and application server is by interconnection exchange network visit metamessage server.Extensibility of the present invention is based on network, promptly, increase along with the network bandwidth, under the prerequisite that does not change system architecture, only need to increase metamessage server, load balance server and the network storage equipment, network server system just can be supported the more application services device and more jumbo, more high performance data, services is provided.
Metadata among the present invention and data centralization are stored on the network storage equipment, and their visit is all finished by the interconnection exchange network.The centralized stores of data makes that manageable per capita data volume improves greatly, is convenient to adopt centralized data management, thereby improves the quality of data management and the reliability of data greatly.The centralized stores of data makes data capacity have good expandability, and only needing increases the network storage equipment, just can increase system memory size.Based on network data and metadata access interface can be easy to realize immediate data visit, make system polymerization I/O throughput almost with the proportional growth of the quantity of system memory devices, thereby provide high I/O performance to server.Because the visit of data is based on network, along with the increase of the network bandwidth, the I/O performance of system also increases thereupon; Only needing increases memory device, and the data, services of more jumbo, higher polymerization I/O throughput just can be provided.
Metamessage server among the present invention and load balance server are system's storage private server fully.Like this, the system server of storage system is clear the separation with application server.
As shown in Figure 3, application server outwards provides various services, and the various user services of operation comprise Email, WEB, Streaming Media and database etc. on application server.Application server is by metamessage server and load balance server access metadata information, by the data on the interconnection exchange network DASD.Because metadata information is that the system server cluster provides by load balance, thereby can obtain high metadata service performance; Owing to adopt the immediate data visit, thereby can obtain high data I/O performance.Take all factors into consideration, application server can obtain high metadata and data, services performance.
As shown in Figure 4, the metamessage server mainly provides visit and the operate services to metadata.For each file, the request that relative all metadata of metamessage server process are relevant.When if this document is catalogue file, the relevant meta information server also is responsible for corresponding catalogue and is handled request, as inquiring about and read catalogue etc.In addition, the metamessage server is also handled relevant request of file lock and the request of file contract.Owing to take the single mapping mode, greatly reduced the situation that needs distributed treatment.Because the operation of metadata takies 50% system resource approximately, therefore the special-purpose metamessage server cluster of employing can effectively improve the parallel processing to metadata information, improves the quality of metadata service greatly.Owing to adopt dynamic mapping mode, also become back binding mode or dynamic binding mode, when serving, request metadata determines just promptly which metamessage server this metadata information is mapped on, can effectively regulate the load of each metamessage server, make the load of metamessage server cluster be in balanced state, thereby whole resource that can the better optimize system server provides comprehensive whole high-performance metadata information service.Along with the increase of the network bandwidth, only needing increases the metamessage server, needn't change system architecture, just can improve the performance of metadata service.Therefore, the metadata service has good expandability.
As shown in Figure 5, the load balance server is finished file to the dynamic mapping of metamessage server and the mobile equilibrium of system load.The decision that file dynamically shines upon need be taken all factors into consideration load, the logical communication link between file and the user's of each metamessage server specific (special) requirements.By the load on the dynamic adjustments metamessage server, can at utmost bring into play the performance of metamessage server cluster, thereby make system have good dynamic process and regulating power.
System management table offers management environment of keeper, comprise that the keeper controls and operation automatically, as file backup with duplicate etc.
