Making $€N$€ of Data Center

Planning Your Data Center…


Do you agree…. 1. Businesses are increasingly dependent on their IT infrastructures to drive mission-critical operations throughout the enterprise. 2. Significant cost savings can be realized through data center consolidation and right-sizing. 3. And every business needs a business continuity plan that includes disaster recovery, backup and remote operations. 4. Continual evolution of infrastructure technology is transforming the modern data center. Advances in network bandwidth are making it possible to store and access mission-critical applications and data remotely.

1. Infrastructure management, including technology deployment, is a huge drain on IT resources. 2. According to Gartner Group, an average of 78% of an IT budget is spent just managing existing systems and software infrastructures. 3. Unfortunately, IT is often resource-constrained and barely able to manage their current environments, much less focus on their company's core competencies.


1. Telecommunications Industry Association (TIA) has issued a standard called ANSI/TIA-942-2005: Telecommunications Infrastructure Standard for Data Centers. 2. Most network equipment is replaced in 3 to 5 year cycles, cabling is expected to serve multiple generations of devices over a 10 to 25 year period. 3. Well-designed cabling infrastructure provides the needed flexibility and scalability when reconfiguring or expanding data center services. 16
