Abstract: Today Data Centers are critical for corporal operations, monitoring networks and keeping control over all business intelligence activities. Businesses thrive over the operations ofdata center today. Data Center systems are like building or a portion of building whose primary function is to house a computer system and its support areas. This in-turn also saves the cost estimates of the organization plus it makes high-end system easily available virtually which are not just as good as but definitely more and more efficient than the so-called physical machine.Whenever you hear talking about efficient IT-utilization in business environments, you will also hear about virtualization and its advantages over the traditional IT-models. If you want to keep the company’s IT-infrastructure up to date, you have to know about utilizing virtualization methods and implementations. Today many organizations find themselves in a situation where they have their data centers filled with underutilized hardware resources. This situation accumulates from the trend of distributed computing and client/server models starting from the late 1980s. As distributed systems and servers were cheap, at the time these solutions provided fast, cost-effective and easy to deploy IT systems. Over time these IT systems became hard to manage, complicated and distributed underutilized systems, resulting in an inefficient use of floor space and excessive power consumption in the data center. Virtualization and more specifically physical to virtual server consolidation provides a solution to these so called “server sprawls”. (IBM 2005, 2). This paper goal will concentrate on virtualization usingserver consolidation using a bare-metal hypervisor platform VMware ESXi 4.0/4.1/5.0. Thesis work will introduce virtualization using different server virtualization platforms, both commercial and non-commercial, mainly concentrating on VMware Infrastructure 3 products. In the practical part a single physical production server is consolidated into a VMware ESXi 4.0 virtual environment. Our basic objective is to help all those Poor Educational Institutions, NGOs, Orphanage Schools who actually run a zero-profit “businesses” with a noble intention and who usually have less budget on computer hardware but still desperately in need of a good Computer Center to educate their students with as equal computing experience as the wealthy institutions usually have. This paper is based on the practical implementation of the Virtual Data Center for VJTI Mumbai for educational purposes. The snaps included are taken by snipping tools to demonstrate this live.
