a. O&M participation in pre-planning and design can make up for the designers' lack of knowledge about system operation and management, improve design quality, and avoid or eliminate design deficiencies.
b. Operations and maintenance to participate in the pre-planning and design, the needs of the operation and maintenance phase can be fully considered in the planning and design.
c. O&M participation in pre-planning and design can fully understand and grasp the structure, reliability weaknesses, legacy problems and potential risks of the maintained system, which helps to improve the quality of O&M and make O&M plans and practical transformation plans based on them.
For the problem of not being able to correctly treat the difference of tendency, preference, limitation, and constraint, and not complying with the scientific design principles, the following suggestions are made.
a. Influence of individual decision makers in approval and decision making should be avoided, and some key functions should be deleted and adjusted according to the opinions of individuals, resulting in the final delivery of data center functions that cannot meet the operation and maintenance requirements.
b. It should avoid being driven by tendency, preference or interest. In the planning and design stage some equipment vendors may influence the program development and equipment selection of planning and design personnel by exaggerating equipment performance and confusing concepts.
Server racks may need to deploy 100 percent DC power, or 100 percent AC power, or a combination of the two.
For example, if a data center is being built for hosting purposes, there may be a need to have an AC (UPS) power supply system, while if it is to be a telecommunications facility, this may require the deployment of a DC power supply system. Knowing this will give you an idea of the size and scale of the DC power or UPS power system required.
When deploying backup batteries, it is best to configure them based on a 15-minute standby discharge time. Deploying backup batteries this way does not significantly increase capital expenditures, and while this will be difficult to justify, it is more cost effective. Companies need to improve the redundancy of backup generator sets, rather than waste more money in increasing the number of batteries.
