A Virtual Facility (VF) is a highly realistic digital representation of a data center.
The term "virtual" in Virtual Facility refers to its use of virtual reality, rather than the abstraction of computer resources as seen in platform virtualization. The VF mirrors the characteristics of a physical facility over time and allows modeling all relevant aspects of a physical data center with a high degree of precision.
VF Model features[edit]
A standard VF model includes :
- Three-dimensional physical facility layout
- Network connectivity of facility equipment
- Full inventory of facility equipment, including electronics and electrical systems such as power distribution units (PDUs) and uninterruptible power supplies (UPSs)
- Full air conditioning system (ACUs) and controls within the room
The term Virtual Facility was introduced by Future Facilities, a data center design consultancy focused on delivering Design and Operational solutions, to address the emerging environmental problems facing the modern Mission Critical Facility (MCF). The concept is, in essence, a combination of the fields of virtual reality (VR), computer simulation, and expert systems being applied to the specific domain of facilities.
The VF type of computer simulation allows for detailed analysis and prototyping of air flow in the data center by making use of computational fluid dynamics (CFD) techniques. This allows the airflow and temperatures of the facility to be analyzed visually (scientific visualization) and numerically to study and predict what would happen in a real facility. The importance of scientific methods in the design of mission-critical facilities has become a necessity, since the performance gains predicted by Moore’s law go hand in hand with a rise in power and heat dissipated by equipment. Rules of thumb have proven to be no longer adequate.
VF applications[edit]
- Greenfield design
- Asset management
- Troubleshooting existing data centers
- Making existing data centers more resilient
- Making existing data centers more energy efficient
- Cost prediction
- Staff training
- Capacity planning
- Load growth management
The VF model is currently being employed by many large organizations as a way of virtually assessing a situation before having to commit large sums of money to trying to solve the problem in a real facility.
It is essential to know whether adding new equipment or changing equipment will cause a logistical or thermal problem. The VF allows the designer or operator to assess the best course of action and gives an in-depth understanding of counterintuitive behaviors.
