In this segment of Ask Katrina, she answers questions about rack U space, the commonly used rack, and a 19 inch rack.
Question 1: What is a “U space”?
A “U” or “RU” is a unit of measurement that is commonly referred to when discussing rack-mounting equipment. A “U space” is 1.75 inches and is commonly 3 hole spaces tall.
Question 2: What is the most commonly used rack?
We find that most Rack Solutions customers typically have a 4-post square hole rack. It’s called a “4-post rack” because there are 4 uprights and as you can see the holes of the rack are square.
Question 3: What is a 19 inch rack?
A 19 inch rack is the standard EIA-310 server rack. The term “19 inch rack” comes from the width of the equipment in the rack.
