Environmental Impact Flashcards
Hot Aisle
Hot air circulation pattern where rows of server racks are oriented so that the front of servers face each other. Tunnel between servers - both are giving hot air from servers racks to center (in between) their edges. This hot air is taken to the ceiling oriented points taking air away from the room.
Cold Aisle
Cold air circulation pattern where rows of server racks are oriented so that the front of servers face each other. Tunnel between servers with cold air coming from floor to the servers
ESD
Electrostatic Discharge release of static electric when two objects touch. Electronic Discharge can damage or destroy electronic components. It can be minimized by grounding workbenches, mats, bags, wristbands
Brownout
Prolonged period of high voltage
Environmental Baseline
Baseline of implementing environmental controls for computers, transmission mechanisms which are sensitive for environmental factors - such as heat, humidity, air flow or power quality
SAG
Helps companies in the identification of critical information infrastructure requirements and potential shortfalls.
UPS
One of power recovering solutions Ultimate Power Supply
Power
Continuous and clean filtered power consistent voltage
Temperature
ACCEPTABLE TEMPERATURE FOR SERVERS 18-27 C
Humidity
Acceptable humidity 50-70%
Surge
A brief over-voltage spikes or disturbances
Fire
Permanent fire isn’t room, can be managed thru fire detection and suppression capabilities
RFI
Radio frequency interference-the presence of unwanted signals or electrical energy that detrimentally impact a radio communication system, can be managed by proper WiFi routers management and copper cables should be shilted
Blackout
Prolonged period without power
EMI
Electromagnetic interference (EMI), also called radio-frequency interference (RFI) when in the radio frequency spectrum, is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction.
