Improving utilisation
Part III

Cost-effective scaling
The combination of simplifying operations and improving utilisation allows organizations to take advantage of a third opportunitycost-effective scaling. By using industry-standard building blocks (server and storage hardware) and standards-based, integrated systems management tools, organisations can pay as they grow and as demand dictates. The ability to add capacity whenever needed ensures a productive, scalable

and compatible environment, without having to over-invest in technology just in case it is needed some day. Organisations can add servers and storage to meet the predicted demands and requirements of their business. These same organisations can then dynamically deploy or reprovision the resources in their server/storage infrastructure to meet peaks in demand via a common pool. To cost-effectively scaleto pay-as-you-grow and allocate existing resources how and when neededprovides tremendous benefits. IT budgets and resources can be managed to provide the optimum amount of computing horsepower and capacity for current needs, while capacity can be added

quickly and seamlessly when needed for planned and prolonged requirements. New technologies for the datacenter of the future will allow dynamic utilisation of existing resources based on policies and procedures that dictate how to handle seasonal or unplanned demands. This brings significant flexibility and control to the IT infrastructure and the ability to more efficiently meet the needs of the organisation.

Imagine a flower wholesaler in the months before Mother's Day. It is the busiest time of the year, and parts of their IT system will need to scale during this time. Their order and production volumes will dramatically increase, as will the needs of their procurement, order entry and billing systems. Rather than purchasing systems to have on-hand just to meet these spikes, the datacenter of the future will enable a dynamic reallocation of resources to support these needs. Computing cycles can be borrowed from other devices supporting less mission critical systems, such as e-mail or file/print during this time, and then be allocated back for normal demand.Dynamically deploy additional resources as demand dictates.
