Grid computing pools and provisions groups of servers depending on business demands, and it is a key part of the next-generation data center.
Oracle Real Application Clusters (Oracle RAC), a key component of Oracle Grid Computing.
Carbon emission is a problem of Data Center.
Excessive energy consumption becomes an issue for a data center .
It can limit the growth of that data center. There can be enough money, enough physical space, and enough business requirements to grow the data center, but sometimes the actual power availability into the building can become a limitation.
The greatest consumers of energy in the data center are heating and cooling. The rule of thumb is that about half of the energy going into a data center is for air conditioning to cool the equipment that produces heat. “Only a small proportion of the energy going into a data center produces the data processing that you really want.
Many servers run at 50 percent or less of their capacity but still have to be kept running. Virtualization helps us run individual servers at a much higher capacity, which means we don’t need to run nearly as many servers for the same amount of data processing.
Green Computing
The Oracle Grid Computing architecture can improve energy efficiency and data center productivity, making a “greener” data center. Some of the enabling functionality includes the following:
* Server virtualization and consolidation using Oracle Real Application Clusters, Oracle Application Server clusters, and Oracle VM save energy and lower system management overhead.
* Storage virtualization consolidation using Oracle Automatic Storage Management and Oracle Advanced Compression can save energy because companies that use fewer disks will consume less power. More-centrally managed storage also means less administrative overhead.
* Workload management using Oracle Enterprise Manager allows companies to manage spare capacity to provide more processing power to development, test, and production systems.
