HP Industry Standard Servers White Paper July 2003 HP ProLiant DL360 Generation 3 Server High-Density Deployment [Document No.
HP ProLiant DL360 G3 Server High-Density Deployment Preliminary Introduction This white paper is a planning guide to expedite concentrated deployments of HP ProLiant DL360 Generation 3 servers in a single rack. This information is intended for field systems engineers, IT managers, installation technicians, and any personnel tasked with the installation and maintenance of the ProLiant DL360 G3 server.
HP ProLiant DL360 G3 Server High-Density Deployment Preliminary Glossary Table 1. Glossary of Power Terms Term Description High Voltage 180 - 264 VAC (200-240 VAC nominal) supplied to areas where load requirements are such that high voltage is more economical. Common in commercial applications in North America, numerous foreign countries also use this range as the AC appliance standard. Inrush Current A high, momentary current draw occurring when power is first applied to electrical systems.
HP ProLiant DL360 G3 Server High-Density Deployment Preliminary Table 1. Glossary of Power Terms Term Description Volt-Ampere (VA) A rating of apparent power (i.e., the amount of AC power that is available to or can be handled by utility equipment) measured with a volt meter and an ammeter. In single-phase systems VA = E × I, where E = volts, I = current in amperes. In three-phase systems VA = 1.73 × E × I. Watt (W) A rating of true power consumed by the product and measured with an input power meter.
HP ProLiant DL360 G3 Server High-Density Deployment Preliminary ProLiant DL360 G3 Server Power Requirements In the standard single-processor configuration, the ProLiant DL360 G3 server includes one 325-watt power supply that can operate off high or low voltage AC power. Single power supply units can be upgraded to a dual-power supply configuration with a redundant power supply option kit. The power supplies are hot-pluggable, allowing live removal and replacement.
HP ProLiant DL360 G3 Server High-Density Deployment Preliminary Power Distribution Solutions HP recommends using power distribution units (PDUs) in installations where a number of server units can place serious loading demands on the AC power bus. HP offers PDUs that provide safety and reliability to multi-server installations. The PDUs described in this white paper offer 0U and 1U mounting options and feature circuit-breaker protection of equipment in groups.

HP ProLiant DL360 G3 Server High-Density Deployment Preliminary Power/Jumper Cords Although PDUs and servers are typically shipped with power cords, the physical and/or electrical requirements for a particular configuration may require different cords. WARNING: Never cut or splice cords to accommodate a configuration. Personal injury or equipment damage could result in the use of improper power cords. The correct factory cord should always be used.

HP ProLiant DL360 G3 Server High-Density Deployment Preliminary In-Rack Local Consoles With an in-rack local console, all equipment, servers, switchboxes, keyboards, keyboard drawers, and video displays are installed together in the same rack. The HP switchboxes mount behind the keyboard drawer and do not consume extra U-space in the rack. Using the TFT5600 RKM and an IP console switch will consume a total of 1U to accommodate up to 128 servers.

HP ProLiant DL360 G3 Server High-Density Deployment Preliminary Planning Rack Configurations You must consider several important factors 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 Interf
HP ProLiant DL360 G3 Server High-Density Deployment Preliminary Rack Management Systems To determine the best rack management solution, consider the service and upgrade demands of the servers deployed in the rack. Universal Rack Rails The ProLiant DL360 G3 server design supports deployment in many environments. The server ships standard in a Universal Rack Rail that works in both round- and square-hole rack cabinets.
HP ProLiant DL360 G3 Server High-Density Deployment Preliminary 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 figures: • • • Calculations are based on formulas using actual measurements of equipment running various exercise utilities.
HP ProLiant DL360 G3 Server High-Density Deployment Preliminary Figure 5. Opening Screen Of Power Calculator Utility The power calculator is convenient for small server system planning or for making minor additions to existing installations. For a more thorough analysis of a complete installation the Rack/Site Installation Preparation Utility is recommended.
HP ProLiant DL360 G3 Server High-Density Deployment Preliminary Rack/Site Preparation Utility The Rack/Site Installation Preparation Utility will calculate all power, vertical rack space, and air flow requirements for a complete server installation. In addition, the Rack/Site Installation Preparation Utility includes sub-calculators for determining the power requirements of individual components. The Rack/Site Preparation utility is accessed through the HP active answers web site.
HP ProLiant DL360 G3 Server High-Density Deployment Preliminary To use the Rack/Site Installation Preparation Utility Select either the Express or Advanced mode of calculation. Express calculation uses pre-set values for components and can be used for producing a quick estimate of system requirements. Advanced calculation requires user to configure individual components and is recommended for final installation planning. If Express mode is selected, proceed to step 5. 1.
HP ProLiant DL360 G3 Server High-Density Deployment Preliminary Power Configurations Examples The high/low voltage and dual-power supply capabilities of the ProLiant DL360 G3 server makes it adaptable to a variety of power configurations. Each of the following examples suggests a method of power distribution for a group of servers mounted in a rack.

HP ProLiant DL360 G3 Server High-Density Deployment Preliminary Conclusion The load requirements of high-density server installations can be significant. Careful planning using accurate calculations and providing overhead compensation for peripheral devices can greatly reduce the chances for downtime due to power problems. Completing the Installation To complete the installation: 1. Install side panels on the outsides of the end racks. 2. Install the front and rear doors. 3.
