determining the power distribution needs for a rack of high-density servers requires considering the following factors: • Voltage level provided by the facility • Type of power connectors to be used • Estimated power consumption • Power redundancy • System expansion • Serviceability Failure to - HP DL360 | Critical factors in intra-rack power distribution planning for high-d - Page 3
such as circuit monitoring Power level and phase PDUs are designed to distribute a specific amount of current at either a low-line (100 - 127 VAC) or high-line (200 - 240 VAC) voltage range, depending on which level is supplied to the rack. Most HP server equipment features auto-sensing input - HP DL360 | Critical factors in intra-rack power distribution planning for high-d - Page 4
more common in other regions. For more information on AC power connector types refer to the HP technology brief "Selecting power cords and jumper cables for use with HP ProLiant servers" at the following URL: http://h18004.www1.hp.com/products/servers/technology/whitepapers/datacenter.html 4 - HP DL360 | Critical factors in intra-rack power distribution planning for high-d - Page 5
low-line or high-line) and amount of power (in VA) required by the equipment in a rack largely determines the type of PDU(s) to use. HP provides online power calculators for making accurate power consumption estimates for most ProLiant servers. Each calculator (Figure 2) allows the IT infrastructure - HP DL360 | Critical factors in intra-rack power distribution planning for high-d - Page 6
power components or cables. These systems may require a rack extension kit (Figure 4) to accommodate cables and PDUs and to allow access to field-serviceable components. Two optional rack extensions kits, a 42U kit and a 36U kit, are available for the HP 10000 series equipment racks. Figure 4.

PDUs that individually support multiple load segments (Figure 5B). In either case, a circuit breaker is associated with each load segment (LS). Figure 5. Segmented power distribution A.

Redundant power distribution Redundant power systems require two power distribution circuits, one for each power bus. Redundant operation requires configuring servers with redundant power supplies, each capable of supporting the full load of a server, if necessary. For redundant operation, the PDU - HP DL360 | Critical factors in intra-rack power distribution planning for high-d - Page 9
involves much more than meeting the power requirement needs of rack-mounted components. Factors including cable routing, air flow, and cooling can also become critical in high-density systems.

Enclosure uses auto-ranging power supplies and supports redundant power supply configurations. Up to four BladeSystem c7000 enclosures can be installed in a standard 42U rack. Figure 7.

Rack configurations for distributing power to HP ProLiant DL servers This section describes power distribution configurations for a high-density server system based on HP ProLiant DL 360 G5 servers. The ProLiant DL 360 G5 is a 1U server that uses an auto-ranging power supply and supports power - HP DL360 | Critical factors in intra-rack power distribution planning for high-d - Page 13
High-density server systems that draw significant amounts of facility power require careful consideration to ensure that safety, availability, and manageability are not compromised. The variety of power distribution products available from HP allows an almost unlimited number of power distribution
