planning rack
configurations
Several important factors are considered when planning a rack configuration:
• The number of servers deployed in the rack
• The number of other devices such as keyboard drawers, video displays, and
console switchboxes that support the servers
• The number of PDUs and their orientation
• The type of rack
• The rack management system
• The console management system
• The remote management system
• Network Interface scheme
All these factors influence floor support requirements, future service and
upgrade requirements, and installation requirements.
online
calculators
HP provides online calculator utilities that simplify the process of determining
power requirements and offer convenient “what if” calculations. These utilities,
available online at no charge, offer several advantages over “scratch pad”
methods using nameplate specifications:
• Calculations are based on formulas using actual measurements of
equipment running a test software utility that exercises the server resources.
• Calculations are based on active components exercised at 100% duty
cycle, generally allowing headroom for a typical installation design.
• Air volume calculations based on measurements taken in equipment
operating with an airflow chamber.
The ActiveAnswers section of the HP website provides two types of online
calculators:
Note: Microsoft® Excel must be installed on the system you are using to view these
utilities.
• Power Calculator utility—calculates the power requirements for a single
DL560 server.
• Rack/Site Preparation utility—calculates the power, vertical space, and
airflow/cooling requirements for a complete rack of equipment.
