Migration of the High-Availability VMware vSphere Cluster
Abstract
The virtual machines platforms find frequent or regular application when designing the telecommunication infrastructures. The implementation-level virtualization system software and continuous updates of its versions remains inevitably relevant. The work focuses mainly on the reasons for virtualization and benefits of migration to an updated version of high-availability computing vSphere cluster development of VMware company using, as an example, a corporate network of one of the Moscow universities.
The authors have formulated the basic benefits available with the initial introduction of a platform of the virtual machines. Among them are allocated: simplifying the network environment configuration, increasing the flexibility of using servers, their availability and quality of server infrastructure management, increasing the hardware utilization factor. In addition, reducing maintenance costs of equipment and electricity is achieved.
In addition to the benefits of virtualization, a clear benefit from the update is gained, i.e. migrations of vSphere cluster to a new version using built-in capabilities meeting up-to-date network technologies. The article also concerns the preparation for migration and the upgrade process itself. An effect achieved as a result of migration is systematized and presented in the form of diagrams to reflect the quantitative evaluation of the received benefits for a number of positions. These are as follows: the reduced load on the power supplies in your server farm, increasing a share of the useful use of CPUs and RAM, reducing downtime of the virtual machines in the host failure, more economic distribution of computing load on physical servers.
The article summarizes the results of migration, shows new functionality and information technology offered to the network owner resulting from the cluster upgrade. In particular, it mentions the introduction of distance learning and the creation of a corporate portal with electronic document management software.
The results of this paper can be useful for specialists in virtualization and network infrastructure, who are engaged in supporting large corporate networks.
