CHAPTER 2 Installation Sites
2.1.2 Utility services
When selecting sites that afford good access to utility services, take the following
factors into consideration:
z Satisfactory availability of electric power
z No suspension or failure of water supplies, or the availability of alternate measures
for water supply
z Access to telecommunication lines
2.1.3 Secure sites
When selecting sites that offer a high degree of security, take the following into
consideration. (Among these factors, those that threaten security will be described
later.) The adverse effects of these factors can be minimized if the structural
requirements for buildings or computer rooms are met.
z Little occurrence of earthquakes, with the effects therefrom minimal
z No danger of damage from flooding and snow
z Little occurrence of lightning
z Easy implementation of fire preventive measures
z No high-level electromagnetic radiation influence
z Little presence of dust and corrosive gases
z Procedures in place for dealing with riots and trespassing, break-ins, etc.
2.2 Buildings
The buildings in which server systems can be installed are broadly classified into the
following forms:
z Dedicated server system centers
z Office rooms converted to dedicated computer rooms
z General office rooms in which server systems are installed for convenience's sake
Except for the last form of installation mentioned above, server system centers and
dedicated computer rooms would best benefit from structural safety considerations,
because they are intended to house server systems handling large amounts of data.
Particularly, the more important a server system center is, the more strict safety
considerations are required.
