Installation and Configuration 5-57 Server Power Distribution Figure 5-8 shows an example of server power distribution for a three-node cluster. Power supply #1 of each server is connected to PDU #1. Power supply #2 of each server is connected to PDU #2. PDU #1 is connected to UPS #1, and PDU #2 is connected to UPS #2. Each UPS is connected to building power. ProLiant Servers Power Supply #1 Power Supply #2 PDU #1 UPS #1 Building Power PDU #2 UPS #2 Figure 5-8. Server power distribution in a three-node cluster Having two PDUs and UPSs in the cluster provides two paths from the servers to building power and means that the cluster stays up and running if a PDU or UPS fails in one of the paths. Storage Subsystem Power Distribution The power distribution for storage subsystem enclosures, with respect to connecting them to PDUs and UPSs, can be configured similarly to the example shown for server power distribution. Each enclosure in an MA8000/EMA12000 Storage Subsystem has two AC power inlets. Substituting power inlets for power supplies and storage subsystem enclosures for ProLiant servers shown in Figure 5-8, you can provide two redundant paths from the storage subsystem enclosures to building power.
