This step also involves identifying a project leader and team members and conducting detailed advanced planning, including a cost assessment, inventory and business impact analysis. Risk assessment With respect to risk, Gartner makes a good point: the less there is to move, the easier – and less risky – the migration will be.
So, part of the risk assessment involves simplifying the data center environment as much as possible, such as through virtualization and consolidation (think converged and hyperconverged systems).
As floor space runs out, more hardware is crammed into the space, thus requiring higher levels of cooling.
Gartner recommends employing the following tools and techniques to manage the energy cost curve: raise the temperature of the data center to 24 degrees Celsius to reduce the level of cooling required; use outside/free air as an alternative to expensive air conditioning; use hot aisle/cold aisle configurations, blanking panels and economizers; and use server-based energy management software to run workloads in the most energy efficient way, such as taking advantage of lower energy tariffs. Data center managers must work with finance and procurement teams to revisit all hardware, lease, software, maintenance and support contracts.
Consolidating these multiple sites into a smaller number of larger sites will often result in financial savings.
Such economies go beyond real estate savings and include getting rid of redundant IT assets, software, maintenance and support, and disaster recovery contracts.
Based on lessons learned through years of research into migrations, it just might help you avoid the mistakes made by others in the past, saving you substantial time and money.
The experts at Gartner have seen their clients execute lots of data center migrations – some successfully, some less so.
But one thing is certain: they learn from both kinds.
In some cases, it may be appropriate to terminate a contract because it's too expensive, while in others, new terms and conditions may secure a lower payment schedule.
Vendors are used to reviewing contracts during downturns. People costs still form the largest single cost element for most data centers, sometimes running as high as 40 percent of the overall costs.
This may result in a performance disadvantage and possibly an energy use increase but will defer the capital expense of a new acquisition.
