Special features of data-processing center and space center upgrade
The article describes an advanced virtualization technology which helps to solve many consolidation problems of computing resources within data center. It also considers subsequent creation of the united educational training and simulation system based on computing resources in a modernization project for the space center “Astron” named after cosmonaut Georgiy Shonin. The paper describes the current technology state and development, the main advantages of changing traditional network infrastructure model into server and desktop virtualization. Desktop virtualization technology provides previously unavailable possibility of computing system dynamic distribution, provides information system fault tolerance, and the most important thing for implementing the concept of educational training and simulation complex – it provides user mobility by graphics adapters virtualization and remote advanced protocols to connect virtual desktops. This project uses the solutions of leading world hardware and software manufacturers, which meet all the requirements to performance and reliability. The result is a united environment with a high degree of automation and simplified administration. The paper describes the composition and application of hardware components in the hardware and software package. The article shows a flow chart describing a data center structure and the quantity of virtual machines in simulators. It also highlights the update process and all problems which are successfully solved in the space center “Astron”. The paper describes typical solutions for a virtual environment and special features of virtualization application in space center workstations. The experience of this project and its results can be successfully used in other works and new simulators.
