Data Center Power and Cooling: A Primer for the Data Center Professional
Today's CIO is faced with a variety of challenges to effective governance of the IT organization. Directives of better aligning IT with the Business and squeezing efficiencies from the IT budget often result in consolidation and selection of strategic outsourcing partners, even in the midst of strategic growth and scale of the business.
Selection of the right data center provider is a key component of this governance task. Offering compelling solutions to the business' requirements requires in depth knowledge of not only the business' strategic direction, but also a firm understanding of the technical aspects of the requirements and how they align with the technical aspects of the data center capabilities.
From a power perspective this paper will outline the anatomy of the electrical systems from power generation to rack level distribution. It will then discuss the basic mathematics involved in power capacity calculations.
From a cooling perspective, the paper will describe the anatomy of data center cooling system and its operation. It will also include basic mathematics used for discussion of cooling capacities.

A Quick Primer on Data Center Tier Classifications
Today a number of companies are either consolidating their data centers or implementing new data center projects. Their decisions are often based on the appropriate "tier level" of the IT facility. The tier level is determined by an industry standard classifi cation system for infrastructure performance. A four-tier system rates a facility's ability to support uninterrupted operation of its data processing activities.
The tier classifi cation model provides an academic and objective benchmark that helps describe and compare the functionality, capacity, and cost of data center infrastructures. At times, the drive to align the uptime of the IT facility with the business becomes bogged down in focusing on tier levels. Other factors beyond tier level compliance can impact uptime performance. In this paper, we will first review data center tier levels, then comment briefly on what is and is not critical to tier level attainment, and conclude with some pragmatic advice about facility assessment.

IPv6 White Paper
Internet Protocol version 6 (IPv6) is a network layer standard developed in the early 1990s to solve one critical issue: The projected exhaustion of IPv4 addresses. Industry experts agree that IP address shortages will become increasing prevalent during the next 10 to 15 years, first in Asia, where IPv4 addresses are least abundant. Eventually, enterprises, service providers, and organizations will run out of IPv4 addresses, prompting a worldwide shift to IPv6-based networks. This white paper explains the Switch and Data Management Company IPv6 solution and provides examples of high-profile Switch and Data IPv6 peering customers.
