The architecture allows shipping the HP POD 240a fully configured with 44 racks of pre-installed IT equipment (Figure 3). When fully populated with HP ProLiant SL170 servers (two servers per rack U), the HP POD 240a can accommodate up to 4,400 servers. Higher server densities may be possible with HP BladeSystem solutions. We can pre- install and test the complete ITE configuration to greatly reduce deployment time and give you quicker ROI.

The HP POD 240a provides optimum performance when populated with HP ProLiant server and storage products supporting management solutions such as HP Insight Control (discussed later). However, the industry-standard racks in the module can accommodate components of your choosing.
Power distribution
The HP POD 240a accepts a 380 – 415V three-phase Wye AC input, commonly available worldwide. Depending on location, the HP POD 240a may require additional power conversion components to connect to the local utility power. In North America, a standard 480V Delta-to-415V Wye step-down transformer may be required to interface the HP POD 240a with utility power. By distributing three-phase power closer to the ITE load, the HP POD 240a power architecture minimizes connections and eliminates numerous transformers that take up space and add heat.
Using a 415V input and distributing 240V single-phase power to the IT load achieves a 50% reduction in copper compared to 208V three-phase distribution. HP ProLiant solutions use universal, voltage-sensing power supplies that can operate within a 110- to 240-VAC range, but 240-VAC operation typically yields the best efficiency.
Power redundancy is a key capability of the HP POD 240a. Power enters the HP POD 240a through two sets of power cabinets at one end of the module (one set shown in Figure 4). The HP POD 240a allows you to tailor your power needs and supports 2N power redundancy such as independent, active-active, or A-Side and B-Side feeds for all components.
