|OpEx||Operating Expense, the ongoing expenses related to operating the data center.|
|Optional Service Network Service||Optional service and network service refer to a series of independent features that can be added to a component, connection, device or other object. Example services might be SSH or Network Address Translation. The service is usually defined with one or more fields to configure and prepare it for launch into production, and may have restrictions on when it can be added or deleted. Although most are optional, you may find that some complete solutions or offers will not operate properly without a specific service or series of services. Some services will also have additional associated charges.|
|Order Status Types||Orders are tracked from submission to completion, and users would be updated of the order status as it is changes. Order status types are as follows: In Quote, Order Received, In Progress, On Hold, Pending Action Required, Completed, and Cancelled.|
|Overcooling||A situation where air is cooled below optimum levels. Typically used in reference to rack inlet temperatures.|
|Patch Cable Installation||Installation of a cross connect patch cable.|
|PDU||See Power Distribution Unit (PDU).|
|Power Distribution Unit (PDU)||This typically refers to one of two pieces of equipment in the power delivery chain.

The other is the smaller "power strip" like device that is used inside the rack to distribute power to the IT equipment.|

|Permissions||Permission is the access granted to a user via the portal through the authority of the Master Administrators. The Master Administrator would grant the user access and permissions to customer portal products and services. Depending on the permissions granted to the user, they would be able to make orders, submit trouble tickets, generate reports, etc. for select IBX. Without permissions from the Master Administrator, the user would not have access to the portal.|
|PF||See Power Factor (PF).|
|PH||See Phase (PH).|
|Phase (PH)||Phase (PH) is a term that describes the relationship between multiple time varying waveforms which have a constant frequency but differ in their position relative to time. It is also used to refer to the number of sinusoidal voltages that make up the power delivery to a device. Most common are three phase and single phase. Single phase consists of 2 conductors between which a sinusoidal voltage is present. Three-phase is a set of 3 or 4 conductors. In the case of 3 conductors, a sinusoidal voltage of a constant magnitude and frequency but differing relationship with respect to time exists between any 2 conductors. In a 4 wire system, the same voltage as in the 3 wire case exists between any of the three "hot" conductors and in addition, between any of the three "hot" conductors and fourth neutral conductor there exists a voltage that is smaller by a factor of the square root of three than the voltage between any of the "hot" conductors. An example of this is a 208/120 three phase system. 208 volts exists between any of the three "hot” conductors and 120 volts exists between any of the "hot" conductors and the neutral conductor.|
|PII hold||PII (Post Initial Install) hold is an ordering hold automatically applied to customers that are Non-Streamlined, or customers that requested a final approval process prior to final submission of orders.

|Potential Transformer (PT)||A device used to transform electrical potential (voltage) from one level to another with a specific ratio. For example, a 480:120 potential transformer transforms voltage on the primary side to voltage on the secondary side with a ratio of 4:1. CTs are typically used to transform large voltages to much smaller voltages so that standard metering equipment can be used on a variety of circuits by measuring the secondary voltage rather than the large primary voltage.|
|POTS||Plain Old Telephone Service|
|Power Factor (PF)||Powere Factor (PF) represents the portion of the apparent power that is real power. The source of power factor is non-resistive components (inductors and capacitors) in the load on an AC power system. These components draw current that is 90 degrees out of phase with the voltage across them resulting in zero real power being delivered. While the power delivery system must carry this current (as well as all the current which does result in real power being delivered), it does no useful work. Power companies often charge a penalty for loads which have a power factor that is significantly far away from 1.0 since the size of the equipment that must be in place is dependent upon the total current delivered, but normal billing is based on real power delivered.|
|PPP||Policies, Procedures, Processes|
|Pressure Differential||The difference in pressure between two locations in the data center. Air flows from higher pressure areas to lower pressure areas. Often, the pressure differential between the underfloor plenum and the above floor space is controlled by varying the speed of the fans supplying air to the underfloor plenum. This allows the addition of vented floor tiles to occur without affecting the air delivered to existing vented floor tiles so that additional IT load may be placed on the floor without disturbing the tuning of the existing floor.|
|Pricing||The one-time and recurring fees presented to the non-streamline customer user for approval to process an order for fulfillment. Until the pricing approval is carried out by the user, the status of the order will remain as 'Pending Action Required'.|

|Waterside Economizer||A system which uses a source other than a chiller to cool the secondary loop water used by the AHUs. This typically consists of either a dry cooler or cooling tower, piping, valves and in the case of a cooling tower, it also includes a heat exchanger since the secondary loop water is treated completely differently than the primary loop water and is typically much "better" water.|
|Water Usage Effectiveness (WUE)||A sustainability metric defined by The Green Grid, which is a measure of the water used on-site for data center operations including humidification and on-site evaporation for cooling or energy production. WUE is calculated by dividing “annual water usage” by the “energy consumption of the IT computing equipment”. The units of WUE are liters/kilowatt-hour (L/kWh).|
|Wet-Bulb Temperature||The temperature of the air measured using a wet-bulb thermometer, that is, the temperature to which a wet surface can be cooled by evaporation. This temperature is affected by both the dry bulb temperature and the dew point of the air. Dryer air has a lower wet bulb temperature. This is a design constraint when utilizing cooling towers or evaporative pads in the cooling process.|

|Work Cell||The area of a rack and the related area immediately in front of and behind the rack. Standard racks are 2 feet wide and 4 feet deep. Standard aisles are 4 feet wide, so half of that space is workspace for a given rack. This results in a standard work cell of 16 square feet. Actual work cell size varies with data center design.|
|WPSF||Watts per Square Foot, a unit of power density. In a data center this is a bulk term that refers to the total load in a space divided by the total area of that space. This is a design parameter for total capacity of the cooling and power systems and is used in conjunction with point load (the amount of load in a small space such as a rack).|
