Data Center Tier Levels and Real Availability

Data Center consolidation and Data Center outsourcing are top of mind for many CIO’s these days. Many companies have ’90s vintage IT facilities that not only do not have the availability to align with the Business‚ operating model but also are struggling to keep up with the power and cooling demands of contemporary computing systems.
The deployment of multi-core processors and blade-based systems has pulled the rug out from beneath many a facility manager. The rapidly growing consumption and cost of energy due to the Data Center have caused many a CFO to define facility operational costs as an IT problem.

Whatever the motivation for the Data Center project, one will have to become familiar with the spirit of the TIA-942 tier classifications as well as the nuances thereof
to exercise the proper degree of due care necessary in planning these very expensive projects. In many cases, the enterprise may be focused on the minutia of TIA-942 because of the desire to align the Business with the proper availability of the IT facility, but this may take place at the expense of pragmatism.
