Racks: These racks come with four vertical posts
and have both front and back rails. Designed for heavier equipment like
servers, these racks can support thousands of pounds. They are more stable and
offer better physical protection, particularly for critical network equipment
mounted at the rear
racks are commonly used in scenarios where airflow control or physical security
is not a requirement.
封闭式机架
Enclosed Racks
server racks have front and rear doors, as well as side panels, making them
essentially self-contained 4-post racks. The doors are usually ventilated to
ensure efficient airflow from the front of the rack to the back, passing
through any equipment that may be installed. These types of racks are also
referred to as rack cabinets or server cabinets.
racks provide enhanced security since the doors and side panels are lockable.
They also support controlled airflow and offer cable management features.
Removable side panels and doors, along with rack-mount rail kits, enable easy equipment
installation or removal while still offering protection against unauthorized
access. Some models also include noise-dampening features, built-in cooling
systems, and the ability to absorb shocks and vibrations. This makes them
well-suited for transportation or for use in unstable environments.
