Glossary - I
This is a glossary of older terms. While many of the definitions are unchanged, some of the definitions may be out of date and some of the terms may no longer be in use in the Data Center industry. This legacy glossary provides definitions for hundreds of information and communications technology (ICT) and data center terms and acronyms. Arranged alphabetically and searchable, the glossary explains common industry vocabulary.

Immersion
A classification type of data center liquid cooling. Source: NVIDIA
Immersion Cooling
A type of liquid cooling used to cool servers, motherboards, CPUs, and GPUs. The entire server is immersed in a liquid. The liquid cools the system directly, and the warmer liquid rises. The hot liquid is then removed from the container and refrigerated separately. The liquid used for immersion cooling is nonconductive and non- corrosive, so that it may be used with electronic components. Source: Supermicro
In Rack Heat Exchanger (IRHx)
A specialized IT Cabinet read door with a built-in heat exchanger that uses a radiator where the hottest servers are operating. Source: Supermicro
Indirect water-cooled
Power that is transferred indirectly to water through an air-to-water heat exchanger located within or on the rack (could be a rear door heat exchanger). Source: ASHRAE
Infiltration
Flow of outdoor air into a building through cracks and other unintentional openings and through the normal use of exterior doors for entrance and egress. Also known as air leakage into a building

Integer
A class of arithmetic, commonly used in computers. Integer arithmetic deals only in whole numbers, e.g., 1, 2, 99, 4563. Any calculation that does not result in a nice whole number is truncated back to a nice whole number and the fractional part is thrown away, e.g., 9/4 = 2 and not 2.25 or two and a quarter. Typically, computers can perform integer arithmetic more quickly than they can any other form of arithmetic, so most programs do as much work as they can in integer. However, most computers have significant limits on the values they can manage in integer format. Besides the lack of fractions, many computers cannot handle integer values beyond the millions. Thus, integers can be used to count time or to keep track of all the pennies in your bank account. However, most scientific applications deal with large values or need to be more precise than just throwing away the fractions. These kind of applications then make use of floating point arithmetic. For the SPEC CPU benchmarks, applications are classified as "integer" if they spend less than 1% of their time performing floating point calculations (which covers most non-scientific applications, e.g., compilers, utilities, simulators, etc.
