What is STACK's Uptime Commitment?
99.999% uptime minimum
What is Voltage?
Voltage is the difference in electric potential between two points
What are the major classifications of procedures at STACK?
MOP, SOP, EOP, AP
What is a Data Center?
A Data Center is a facility that houses computer servers, enabling our modern digital world to function
What formula explains the relationship between voltage, current, and resistance?
Why do data centers produce heat?
Computers and other resistive loads consume electricity and convert it to heat

AC power alternates direction in a circuit, DC flows one direction.
What is the difference between latent and sensible heat?
Latent heat is the thermal energy absorbed or released during a phase change, sensible heat is the thermal energy that causes a direct change in temperature
What are the three potential roles involved in executing a procedure?
Controller, Operator, CMS (Critical Maintenance Supervisor)
What is Human Error?
Human error is an action or decision that was not planned, not intended, or that causes a task or system to fail its goal
How does an arc form in a circuit?
High Voltage or conductors ionize the surrounding air, turning it into a conductive plasma that allows current to jump between conductors.
How is heat rejected from your data center? Explain the full heat path.

What is the difference between stabilization and resolution?
Stabilization means that an event isn't getting worse, resolution means that the system has been restored to normal state.
