Common Data Center ChallengesIncreasing complexityRising costsEnergy and cooling problems
Server total cost of ownership continues to grow, so you have motivation to reduce the number of servers neededWorldwide IT spending on servers, power and cooling, and management/administration*SpendingInstalled base(US$B)(M units)Power and cooling costs x8Server management and administration costs x4New server spendingMany servers, much capacity, low utilization = US$140B in unutilized server assets*Source: IDC Enterprise Server Research, 2007.
Complexity is often a result of unchecked server sprawlWhen you add servers as a stopgap measure to address a short-term demand, there is an immediate and lasting increase in cost, including:•Hardware costs•Management costs–More servers, more racks, more –IT staffstorage systems–Ongoing training–Distributed computing •Site and facilities costsenvironments that mostly sit idle, –Data center space, rack spacewith as little as eight percent of –Power, cooling, security, capacity utilizedmonitoring•Software costs–More servers that require more licenses–Management tools required to maintain performance

IBM can drastically reduce the time required to implement a consolidation, because it has industry-leading processes and tools from its extensive server consolidation service capabilities:Collect—in a nonintrusive way—a snapshot of your existing environment−Applications and their performance demands−Utilization−WorkloadsAnalyze the gathered informationDevelop possible consolidation environmentsbased on different scenariosRecommend a post-consolidation environment

There are many benefits of a consolidated server environment, both “Hard Savings” as well as soft savings and cost avoidance•Cost savingsBased on IBM’s experience, the following represents the typical savings that organizations may realize:–Hardware costs reduced 33 to 70%–Maintenance costs reduced up to 50%–Support costs reduced by as much as 33%–Floor space and facility costs reduced 33 to 50%•Improved IT flexibility•Improved business flexibility•A reduction in costs of new hardware/software to host new projects•Reduces the workload on current staff members , allowing them to work on other projects
