WP-37: Avoiding Costs From Oversizing Data Center and Network Room Infrastructure The physical and power infrastructure of data centers and network rooms is typically oversized by more than 100%. Statistics related to oversizing are presented. The costs associated with oversizing are quantified. The fundamental reasons why oversizing occurs are discussed. An architecture and method for avoiding oversizing is described.

WP-72: Five Basic Steps for Efficient Space Organization within High Density Enclosures Organizing components and cables within high density enclosures need not be a stressful, time consuming chore. In fact, thanks to the flexibility of new enclosure designs, a standard for organizing enclosure space, including power and data cables can be easily implemented. This paper provides a five step roadmap for standardizing and optimizing organization within both low and high density enclosures, with special emphasis on how to plan for higher densities.

WP-76: Modular Systems: The Evolution of Reliability Nature proved early on that in complex systems, modular designs are the ones that survive and thrive. An important contributor to this success is the critical reliability advantage of fault tolerance, in which a modular system can shift operation from failed modules to healthy ones while repairs are made. In data centers, modular design has already taken root in new fault tolerant architectures for servers and storage systems. As data centers continue to evolve and borrow from nature’s blueprints, IT reliability analysis must also evolve to understand new strategies for survival, recovery, and growth.

WP-81: Site Selection for Mission Critical Facilities When selecting a new site or evaluating an existing site, there are dozens of risk factors that must be considered if optimal availability is to be obtained. Geographic, site-related, building, and economic risks need to be understood and mitigated to lessen the downtime effects on your business. In this paper guidelines are established for selecting a new site or assessing an existing one. Common risks that affect the availability of a business are defined and techniques for minimizing these risks are presented.

WP-116: Standardization and Modularity in Network-Critical Physical Infrastructure Failure to adopt modular standardization as a design strategy for Network-Critical Physical Infrastructure (NCPI) is costly on all fronts: unnecessary expense, avoidable downtime, and lost business opportunity. Standardization and its close relative, modularity, create wide-ranging benefits in NCPI that streamline and simplify every process from initial planning to daily operation, with significant positive effects on all three major components of NCPI business value – availability, agility, and total cost of ownership.
