ProLiant BL e-Class server blade enclosure Description ProLiant BL10e server blades are housed in a 3U server blade enclosure (Figure 3). The server blades plug into the enclosure for power and network connections. Each ProLiant BL e-Class server blade enclosure has twenty (20) server blade bays in the front and an interconnect tray bay in the back (for one of three interconnect tray options).

PAGE 18
Compaq ProLiant BL e-Class System Overview and Planning 18 Power Planning The following general guidelines should be followed when planning and installing a ProLiant BL e-Class system: High-voltage deployment is highly recommended (200-240VAC) because of lower current requirements. Both power supplies provided with your ProLiant BL e-Class server blade enclosure should be plugged into an AC power source to assure full power supply redundancy.
PAGE 19
Compaq ProLiant BL e-Class System Overview and Planning 19 Definitions and Theory Single Sources of Failure (SSOF) A server blade enclosure (or rack) can fail if it is dependent on a critical component or resource that is itself vulnerable to failure. This dependence is deemed a single source of failure. Redundancy is based on the types of failures a configuration can tolerate and is characterized by removal of as many single sources of failure as possible.
PAGE 20
Compaq ProLiant BL e-Class System Overview and Planning 20 PDU A PDU has one or two AC power inlets and multiple power outlets (12) to simplify power cord management. PDU Failure The PDU may have an internal failure or its input circuit breaker may be tripped due to over-current. A PDU single source of failure can also loosely be described as a situation when the PDUs have tripped due to over-current.
PAGE 21
Compaq ProLiant BL e-Class System Overview and Planning 21 AC Source An AC source is AC power delivered via an AC wall outlet, main circuit breaker or a building’s power infrastructure. This term also loosely describes AC power delivered to a power supply or PDU. AC Source Failure The AC source supplying power to a component has failed.
PAGE 22
Compaq ProLiant BL e-Class System Overview and Planning 22 The Domino Effect If a power supply, PDU, or AC source fails or is unplugged, the power load is automatically re-distributed. The remaining AC source and PDUs must support 100% of enclosure power requirements. If the resulting load exceeds the capacity of the remaining PDU, that PDU’s circuit breaker may trip, resulting in a potential “domino effect”.
PAGE 23
Compaq ProLiant BL e-Class System Overview and Planning 23 Failure scenario 2 If the AC source for PDU 1 fails (or PDU 1’s power cord is unplugged), PDU 2 must now support the full current load of all enclosures. PDU 2’s output circuit breakers each support a 10-A enclosure, which is within the breakers’ rated specifications. However, this combined 10 + 10 + 10 + 10 = 40-A load exceeds PDU 2’s input rating of 24 A.

PAGE 25
Compaq ProLiant BL e-Class System Overview and Planning 25 Determining Type and Number of PDUs: Redundant PDU Configuration Use the following guidelines if using a redundant PDU configuration to survive a PDU failure or PDU power cord unplug event. In this configuration, each power supply is connected to a different PDU to eliminate the PDU as a single source of failure for that enclosure.
PAGE 26
Compaq ProLiant BL e-Class System Overview and Planning 26 Redundant PDU High-Line Example #1 This example presents a high-line configuration for PDU redundancy supporting one to three enclosures. Figure 13 is valid for high-line PDUs with inputs rated 16 A. It does not support four enclosures at high-line voltage because the total current load of 4 * 5 A = 20 exceeds the input rating of 16 A. See the previous restrictions. Figure 13.
PAGE 27
Compaq ProLiant BL e-Class System Overview and Planning 27 Redundant PDU Low-Line Example This example presents a low-line configuration for PDU redundancy supporting one to two enclosures. Figure 15 is valid for low-line PDUs with inputs rated >20 A. It does not support three enclosures at low-line voltage because the total current load of 3 * 10 A = 25 exceeds the input rating of 24 A.
PAGE 28
Compaq ProLiant BL e-Class System Overview and Planning 28 Non-Redundant PDU Example #1 (PDU P/N 207590-D72) PDU (P/N 207590-D72) is a high-voltage PDU with a current rating of 24 A. The enclosure has a maximum input current requirement of 5 A at 200 volts. 24 A (PDU current rating) / 5 A (enclosure total input current rating) = 4 enclosures per PDU This PDU can support a maximum of four fully configured ProLiant BL e-Class enclosures in a non-redundant configuration.
PAGE 29
Compaq ProLiant BL e-Class System Overview and Planning 29 Positioning PDUs in 22U, 36U, and 42U Racks The position of the PDUs in the rack side panels depends on the rack size, the number of ProLiant BL e-Class server blade enclosures deployed in the rack and the cable management solution. As a general rule, install PDUs from the bottom to the top of the rack. Cabling Guidelines • Do not block airflow of center fans or power supplies with large cable bundles.
PAGE 30
Compaq ProLiant BL e-Class System Overview and Planning 30 Appendix A: Input Current and Thermal Dissipation Calculations The input power is necessary for determining the input current and thermal dissipation. For a given input power, the input current varies depending on the input voltage level. The relationship among the current, the voltage and the power for the power supply input is as follows: Input Current = Input Power/Input Voltage For example: Input Current = 1000 W /110 V = 09.
PAGE 31
Compaq ProLiant BL e-Class System Overview and Planning 31 Appendix B: Input Power Budget De-rating All power requirements for ProLiant BL e-Class server blade enclosures that are discussed in this document are based on the input power of the enclosure. Compaq recommends using the maximum rated power supply input of 1000 W when planning power distribution.
