Using ProLiant BL20p server blades

In this configuration, the rack contains six enhanced server blade enclosures, six 1U power enclosures, and six PDUs. Each enhanced server blade enclosure is populated with ProLiant BL20p server blades and has a 1U power enclosure with four power supplies installed. The 1U power enclosures are connected to two 40 A modular PDUs.

The ProLiant BL20p server blades have a single-core 3.6-GHz processor with 2 MB L2 cache, 4 GB of RAM, and two 18-GB 15,000 RPM SCSI hard drives, resulting in 3,714 VA input. Four power supplies are needed in the 1U power enclosure for redundant power. The 40 A modular PDU has a load capacity of 8,320 VA, so it can support two server blade enclosures fully populated with ProLiant BL20p server blades.
