Introduction This white paper is a planning guide to expedite concentrated deployments of HP ProLiant DL360 Generation 4 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 HP ProLiant server. Use this white paper in conjunction with documents for the HP ProLiant server and HP ProLiant rack deployment products as necessary.
PAGE 3
Power Distribution Solutions HP recommends using power distribution units (PDUs) in installations where the large 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 the equipment. The equipment power can be organized in groups to minimize the impact of power interruption.
PAGE 4
Figure 2 shows a PDU using the 1U rack mounting option. HP recommends this configuration in installations where maximum accessibility to all components is important. The 1U configuration offers the following advantages: • Easy access to all switches and circuit beakers • Easy viewing of circuit status LED • Easy access for service replacement or upgrade Figure 2.

Modular PDU Power/Jumper Cords Although PDUs and servers are typically shipped with power cords, the physical and 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.

Console Management Systems A KVM console management system enables a single keyboard and video console to control multiple servers. A console management system mounted in the rack may be used to manage a single rack of servers or groups of racks. The HP IP console switch products have 16 ports that can access up to 128 servers. The HP IP Consoling Solution combines analog and digital technology to provide flexible, centralized KVM control of data center servers.

Table 4. Local/IP Console Management Options Product Name HP Part No.
PAGE 10
In-Rack Local Consoles With an in-rack local console, all equipment, servers, switchboxes, keyboards, keyboard drawers, and video displays are installed in the same rack. The HP switchboxes mount behind the keyboard drawer and do not consume extra panel 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. One console switchbox can support up to 16 directly attached servers with no user blocking.

PAGE 12
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 Interface scheme All these factors influence floor support requirements,
PAGE 13
Rack Management Systems To determine the best rack management solution, consider the service and upgrade demands of the servers deployed in the rack. Universal Sliding Rack Rails The Universal Sliding Rack Rails and optional cable management solution enable in-rack servicing and provide convenient access to the server cables and connectors. With this solution, a server can be powered down and serviced without disconnecting the server cables or removing the server from the rack.
PAGE 14
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.

PAGE 16
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, HP recommends that you use the Rack/Site Installation Preparation Utility. Rack/Site Installation Preparation Utility The Rack/Site Installation Preparation Utility will calculate all power, vertical rack space, and airflow requirements for a complete server installation.

Figure 7.
PAGE 18
Using 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. HP recommends using advance calculation for final installation planning. If Express mode is selected, proceed to step 5 on the screen. 1. Select the DL360G4 tab at bottom of the screen.

Power Configuration Examples The high- or low-voltage AC power and dual-power supply capabilities of the HP ProLiant 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. These examples illustrate server power configurations and do not take into account such accessories as KVM switches and display monitors that are typically included in an installation.

Conclusion The load requirements of high-density server installations can be significant. Careful planning using accurate calculations and providing adequate additional capacity allowance for peripheral devices can greatly reduce the likelihood of downtime because of power problems.

Glossary Table 11. 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.
