Tiivistelmä
Many companies use cluster systems for their work. It provides a failover, high-availability and greater performance, than just a regular server system. This thesis work provides the information how to implement and configure a high-availability cluster environment with use of two physical servers and virtual machines. Also, it describes server networks, virtualization technology, storage sharing technology, backup technology and clustering.
To achieve the objectives following methods were used: two server nodes were combined into one cluster system, shared storage was attaching to it and virtual machines were created, which in future acted as separate servers. Also, migration and live migration of virtual machines were implemented and backup/restore system was configured. To implement live migration in the cluster, easy backup/restore system and to achieve resource optimization, virtualization technology and shared storage were used.
As the result, high-availability environment was implemented. It provides optimization of resources, easy migration and copying of VMs. And also, live migration inside the cluster and easy backup/restore system was configured.
This thesis work was written for the Mizar Ltd, placed in Russia, Petrozavodsk. The practical part was done with cooperation of company’s IT employees and implemented on firm’s hardware for its needs. With high-available cluster system, downtime of application, in case of failure, is decreased and sensitive applications stay online maximized time and there is no need for company customers and users to wait for application availability.
