What is Rack Servers?

Rack Servers are, as their name suggests, servers that are mounted on racks inside a data center. Racks vary in size but most are 19” wide and 45 U’s tall. A “Rack Unit” (RU) or “U”) is a vertical measurement of 1.75” (44.45 mm). Racks contain bays or multiple mounting slots, each one designated to hold a hardware unit attached securely in the framework.

Rack Servers exist as a low-profile configuration as opposed to more upright tower servers built into a previous vertically standing cabinet unit. Efficient and time-saving, Rack Servers consolidate network resources and minimize square footage.

IT Central Station IT experts are looking for quality components when configuring Rack Servers. It is essential for a Rack Server’s configuration to have simple cable component connectivity. It must have a special cooling system for excessive heat buildup when squeezing so much into such a confined and limited space.

Many infrastructure managers value server density as a quality of rack servers. Density refers to the amount of compute capacity that can be placed on a single rack. This may be measured by processor cores per rack or compute cycles per rack. It’s a constant balancing act, with the desire for density being offset by the realities of heat and energy use. The more compute density in a rack, the more heat it generates (and the more cooling it will require) and the more energy it will consume.

IT Central Station experts are motivated to vertically scale Rack Servers, which adhere to an IEEE IT standard. They are configured in multiples, as loaded but compact physical servers. Rack Servers deliver an opportunity to install many other IT devices within the structure, which also adhere to the IEEE standard, such as SAN devices, Power Backup devices, and Rack Consoles. The addition of Rack Servers adds value to an IT team as hardware vendors are providing software tools to help teams manage servers and often the devices themselves.
