ventilation requirements of the room occupants. Data center areas normally have a
very low human population density; thus the air required for ventilation will be
minimal. In most cases, the air needed to achieve positive pressurization will likely
exceed that needed to accommodate the room occupants. Normally, outside air
quantities of less than 5% make-up air should be sufficient (ASHRAE Handbook:
Applications, Chapter 17). A volume of 15 CFM outside air per occupant or
workstation should sufficiently accommodate the ventilation needs of the room.
Cleaning Procedures and Equipment
Even a perfectly designed data center requires continued maintenance. Data centers
containing design flaws or compromises may require extensive efforts to maintain
conditions within desired limits. Hardware performance is an important factor
contributing to the need for a high level of cleanliness in the data center.
Operator awareness is another consideration. Maintaining a fairly high level of
cleanliness will raise the level of occupant awareness with respect to special
requirements and restrictions while in the data center. Occupants or visitors to the data
center will hold the controlled environment in high regard and are more likely to act
appropriately. Any environment that is maintained to a fairly high level of cleanliness
and is kept in a neat and well organized fashion will also command respect from the
room's inhabitants and visitors. When potential clients visit the room they will
interpret the overall appearance of the room as a reflection of an overall commitment
to exslotence and quality. An effective cleaning schedule must consist of specially
designed short-term and long-term actions. These can be summarized as follows:
Daily Tasks
This statement of work focuses on the removal of each day's discarded trash and
rubbish from the room. In addition, daily floor vacuuming may be required in Print
Rooms or rooms with a considerable amount of operator activity.
Weekly Tasks
This statement of work focuses on the maintenance of the access floor system. During
the week, the access floor becomes soiled with dust accumulations and blemishes. The
entire access floor should be vacuumed and damp mopped. All vacuums used in the
data center, for any purpose, should be equipped with High Efficiency Particulate Air
(HEPA) filtration. Inadequately filtered equipment cannot arrest smaller particles, but
rather simply agitates them, degrading the environment they were meant to improve.
It is also important that mop-heads and dust wipes are of appropriate non-shedding
designs.
