It is true that Further Server Virtualization technology itself has reduced the cost of one time burden of buying may servers. It is true that Server Virtualization has made it possible to use a Virtual Dedicated Server acting as good as a Dedicated Server at a fraction of the cost. But, it is also true that Server Virtualization, despite these savings, has increased the cost of cooling, monitoring of the servers and most importantly, Server Virtualization requires specialized knowledge.
It is often said aptly that, without proper training, Server Virtualization practically can be disastrous. Simply, if the temperature and cooling are not monitored properly, the CPU will burn out to ash.
These unplanned additional costs in Server Virtualization – can be reduced by training on Server Virtualization. All applications that are difficult to predict an I/O- and CPU load, are less suitable for Server Virtualization.
Steps to reduce the cost of Server Virtualization
Hardware aspects : How many servers will be used for the system? What will be the approximate highest power consumption? How much RAM, Hard Disk is expected to be sufficient?
Datacenter aspects : How much power server cooling systems will consume? How much floor area the server will occupy?
Software aspects: Why you are opting for Server Virtualization ? What is the targeted use ? Server Virtualization software for running a web server and that of running a system intense application will never be the same, in fact these factors increases the cost of electricity consumption directly and for cooling, indirectly. Also it is important to think about the Operating System.
Resources for running Server Virtualization : Establishing a Datacenter in the far away place from the main city has some benefits – social and legal aspects are carefully handled in this way. But, it is important for any Datacenter for running Server Virtualization, how it is easy to reach the place for both the skilled and semi-skilled workers.
Constant Flow of Water is as much as important as the electricity and bandwidth. Labor charge is often calculated over above the cost of these elementary resources for running a Server Virtualization based data center. The cost for both the skilled and semi-skilled workers in India is relatively lower but the cost of Bandwidth increases the cost of Server Virtualization disproportionately.
Conclusion on Calculating the costs of Server Virtualization
Server Virtualization is not an isolated phenomenon. Just like any other industry, a datacenter for running Server Virtualization needs excellent calculations.
