For one of its long-standing clients, LAN Projekt, at the turn of the years 2012 and 2013, carried out virtualization of servers.
The server infrastructure was composed of Microsoft Windows 2003 file server, which at the same time served as the domain controller and mail server, operating under Linux OS.
The reasons for initiating the migration process to virtual environment were the following:
a) the hardware on which services were installed was becoming obsolete
b) there was insufficient disk space for the file server
c) the need to start up a new server operating under Linux OS, designed for handling the implemented business application
The purpose of the process was minimisation of the costs of investment and IT infrastructure maintenance, with the assumption that the impact of migration of the existing services and data on the business functions of the Client will be as limited as possible.
As suggested by LAN Projekt, the Client chose virtualisation of the IT systems in use (the operating system, applications, data) based on a new tangible server and Microsoft Windows Server 2008/R2 software. The new server, after deploying the hyper-v virtualisation manager function, served as a platform for starting up the file servers with domain controller function and business application server, as well as the planned start-up of another virtual server (Microsoft Server 2008 R2)
The virtualisation process made possible elimination of two 5-year-old tangible machines, reducing the risk of breakdown of already worn out hardware.
As the platform for virtual machines control host, a state-of-the-art power-efficient IMB series x3650 M4 server was used, which resulted in reduction of power energy consumption for powering the servers and coolers.
