Is Your Data Center Ready for Virtualization?: Important Power Considerations for Virtualized IT Environments
Server virtualization has come to be an important means of saving costs for data centers. With efficient server virtualization, data centers can save in terms of the server count, footprint, energy consumption and expenditure on cooling. With all the palpable advantages that virtualization provides, it comes with some discreet challenges. For instance, while virtualization of servers saves on power, the saving is variable in nature and can sometimes be lopsided. Simultaneously, while virtualization requires a lesser number of servers, these turn out to be more critical. While it allows users to reallocate applications, the support infrastructure of virtual servers often doesn't have similar capabilities. Finally, while such a data centre has smaller footprint, the efficiency that they provide is sometimes suboptimal.This paper tries to study and understand some practical and cost-effective means of addressing these challenges. This is an important means of improving data center efficiency. The paper looks at power-related challenges and tries to find the appropriate technologies that can resolve these issues. Virtualization can enable providers to understand power and data center performance. This also helps control costs while enhancing the value of existing data center facilities. The paper takes up issues one by one to provide a relevant solution. These solutions are able to utilize the benefits that come from virtualization and server consolidation.
