How to deal with the pain point of network operation dimension in server virtualization?

The most obvious feature of the Cloud Age data center is the large number of applications of virtualization technology, which makes the objects of operation and maintenance management change. Previous equipment is real, location is relatively fixed, relatively intuitive management. The result of virtualization technology is to "pool" these resources, so that all management objects into virtual, flexible migration of the logic exists, the resources in the data center physical location visibility becomes difficult. Cloud Data center era, what kind of network operational problems? With the cloud computing and large data entering the landing phase, the new generation of data center is the key to support cloud computing and large data development strategy, but the attendant problem of transportation and peacekeeping management has become a problem facing the administrators. The most obvious feature of the Cloud Age data center is the large number of applications of virtualization technology, which makes the objects of operation and maintenance management change. The adoption of virtualization technologies can reduce the number of physical servers and devices in the datacenter and provide greater flexibility to meet rapidly changing business requirements. But at the same time, the previous equipment is real, location is relatively fixed, relatively intuitive management. The result of virtualization technology is to "pool" these resources, so that all management objects become virtual, flexible migration logic exists. The visibility of the resource's physical location in the datacenter becomes difficult. One aspect of the problem is the network configuration of the data center. The need for continuous communication and coordination between network managers and server administrators in data centers, and how to efficiently manage such massive devices and applications when failures need to be checked and eliminated in time, and when processes need to be tracked. For example, a large Internet Data center, a shelf will be equipped with thousands of switches, managers are also several people, how to ensure that they finish the work in a short time, how to track and audit and so on. When a business system is facing a failure, how to quickly locate the physical or virtual network problems, these need to be implemented through automated management technology. On the other hand, the boundary of network and server become more fuzzy, which brings the problem of cooperative dispatch of network and computing resources. The normal operation of the business depends not only on the reasonable scheduling of resources on the server, but also on the reasonable dispatch of network connections. In server virtualization application, VM Migration inevitably causes the dynamic of its access location. This requires that the physical network configuration can provide on-demand management capabilities, so as to ensure the VM connectivity to the network, security, reliability requirements. Therefore, it is a key problem for data center managers to better control resources, locate VM and physical switch connection and solve resource migration problem. The key to realize the data center based on the business scheduling and finally realize the automation is to realize the gap between the network and the computation, and achieve the resource fusion management and intelligent Dispatch. How to deal with the problem of network operation of cloud computing and virtualization? From the above can be seen, facing the operational problems, the administrator needs a set of effective systems for the cloud data center, through this system, that can playThrough network, computing the gap between the physical resources and virtual resources to achieve the integration of management, but also through the visualization of the service distribution, the final implementation of automated network operations, so as to improve the data center operation and maintenance efficiency. Agile Controller is a professional platform for cloud computing data Center, which aims to build a simple, efficient and open cloud data center network for customers, which supports the rapid development of cloud data center business. First of all, Huawei Agile Controller is able to implement collaborative control between physical and virtual networks, and to display the dependencies or connections between physical Tor switches, physical servers, virtual switches (VSwitch), virtual machines (VMS) in a topological way. The key point is to show the connection between network resources and virtual server resources, in a topology map, both physical network topology and virtual network topology are presented to facilitate the joint troubleshooting between network administrators and system administrators. 498) this.width=498 ' OnMouseWheel = ' javascript:return big (This) ' src= ' http://s6.51cto.com/wyfs02/M02/53/95/ Wkiol1rr--liqkrraacfloopi2c418.jpg "width=" 548 "border=" 0 "height=" 460 "alt=" How to deal with the network operation in server virtualization pain point? "/> Second, in the virtual machine migration , Huawei Agile Controller can obtain VM migration messages via interface, automatically migrate network-side data between the source and host Tor, and realize the automatic migration of network configuration when virtual migration occurs. The migration scope supports static data (ACLs, QoS, VLANs) and dynamic table entries (DHCP snooping binding tables), while perceiving virtual changes, recording virtual resource change logs, and tracing traceability of resource migrations. In addition, Huawei Agile Controller also support trill network simple deployment, for large data centers, one shelves to configure multiple switches to build Trill network, if the deployment of each device still requires professional human intervention deployment, then the difficulty and cost will be high, Agile Controller can simplify Trill network deployment and achieve a truly meaningful 0 configuration. First of all, agile controller The integration of the DHCP server, Python script Editor, software and configuration file server and other multi-function modules, the controller preset typical scripts and configuration templates to simplify customer configuration. The automatic software version and the configuration file, the network topology automatically calculates, according to the Spine/leaf connection relation automatic configuration trill (nickname and link type etc.), automaticallyCompletes Trill node insertion. Summing up, in the cloud-era data center, IT managers must be able to understand their own IT resources at all times to understand the relationship between virtual machines and physical servers, while clearly establishing the relationship between physical servers, virtual machines, physical networks, virtual networks, And the relationship between these elements and the data center's business system is established. All of this, Huawei Agile Controller Agility Controller can help the administrator to achieve, thereby greatly reducing the complexity of the operation dimension.
