Virtualization Simplified


Virtualization was invented thirty years ago to virtualization expensive and large main-frames. As hardware prices went down. Gradually virtualization was forgotten as hardware prices gradually reduced. More recently virtualization at levels (Hardware, Switching and Storage) became important to improve security, realiability, availability, reduce cost and provide flexibility.

Virtualization brings several advantages to the design of modern computer systems including better security, higher reliability and availability, reduced costs, better adaptability to workload variations, easier migration of virtual machines among physical machines, and easy coexistence of legacy applications. Many vendors including Sun, IBM, and Intel have already announced virtualization solutions.

Data Centers are the main culprits of consuming huge energy and emitting huge amount of CO2, which is very hazardous for global warming. Virtualization technology provides the solution but it has many overheads, like single point of failure, total cost of ownership, energy and efficiency calculations and return of investment. The other problem faced by IT managers related with the proper implementation of Virtualization technology in data centers to cop up with the above defined problems.

TechnoPlanet Enterprise - Virtualization TechnoPlanet Enterprise comes up with a five step model to properly implement virtualization. It starts by categorizing servers and their associated applications and resources into different resource pools. It is important to consider that virtualization not only needs to characterize the workloads that are planned to be virtualized, but also target the environments into which the workloads are to be applied. It is important to determine the type of servers, their current status whether idle or busy, how much it will cost to implement server virtualization, the type of technology needed to achieve the service levels required and finally meet the security/privacy objectives. It is also important for the data center to check whether it has the necessary infrastructure to handle the increased power and cooling densities arise due to the implementation of virtualization. It is also important to consider the failure of single consolidated server, because it is handling the workload of multiple applications. It poses many challenges to the data center physical infrastructure like dynamic high density, under-loading of power/cooling systems, and the need for realtime rack-level management. These challenges can be met by row-based cooling, scalable power and predictive management tools. These solutions are based on design principles that simultaneously resolve functional challenges and increase efficiency. This model can be followed by IT managers to properly implement virtualization in their data centers to achieve efficiency and reduce carbon footprints.
