Using ProLiant BL30p server blades

In this configuration the rack contains four enhanced server blade enclosures, four 1U power enclosures and six PDUs (Figure 10). Each enhanced server blade enclosure is populated with ProLiant BL30p server blades and has a 1U power enclosure with six power supplies installed. The 1U power enclosures are connected to two 40 A modular PDUs.

The ProLiant BL30p server blades have two single-core 3.2-GHz processors with 2 MB L3 cache, 4 GB of RAM, and one 60-GB hard drive, resulting in 5,768 VA input. Six power supplies are needed in the 1U power enclosures for redundant power. The 40 A modular PDU has a load capacity of 8,320 VA, so it can support one server blade enclosure fully populated with ProLiant BL30p server blades, with 2,552 VA extra capacity. Each power supply has a load of 1,923 VA; an extra power supply unit can be connected to each PDU and cross-wired, as shown in Figure 10.
