The Top 5 Things to Keep in Mind When Buying a Server Rack
The type of rack you choose will depend on the cooling methods used in your environment. Baseline kW of heat output per rack varies widely, depending on type and density of equipment, and can be anywhere from 4 kW-12 kW or more per rack, with some experts estimating that the rise of high-density environments and designs for future equipment will result in an output of 30-50 kW per rack. (4) Fully Perforated Racks: Select a fully perforated rack for maximum air flow if the primary method of cooling in your datacenter or server room will be ambient air cooling (fans, air handlers, blowers, and/or Computer Room Air Conditioning (CRAC) units and a raised floor). Fully-Sealed Racks: Choose a fully-sealed rack if a liquid cooling unit or rack air conditioner will be used in your environment. As power-intensive applications and server densities have increased, Liquid Cooling Units (modular, temperature-neutral high-density cooling solutions that utilize air/water heat exchangers to provide uniform, effective cooling) are increasingly being used. One of the main benefits of self-contained liquid cooling units is that they result in little or no impact on the existing HVAC system. Liquid cooling units are mounted at the rack base, in a rack “side car” with three cooling modules possible per equipment rack, and can provide a total cooling capacity of 30kW. Rack air conditioners are generally not used in traditional datacenter environments that have adequate CRAC systems. However, if IT equipment will be placed outside of a controlled datacenter environment, such as in a warehouse or factory, rack air conditioners are sometimes used.Pages: 1 2 3 4 5 [6] 7 8

Health Hazards in Your HomeHealth Hazards in Your HomeAuthor: Paula CherristThe EPA has found that the air quality inside most condos and houses is three times as bad as the air quality outside in terms of pollution and harmful fumes and gasses. Most home and condo owners aren't aware of this fact, but they are probably aware of the way this type of pollution makes them feel in terms of health. Everything from breathing problems, allergies, headaches, nausea and even in some cases the possibility of increased risk of cancer can result from being exposed to certain chemicals commonly found in the home and in home furnishings and finishes. |
