HP Cluster Platform Interconnects v2010 Using InfiniBand for a Scalable Comput - Page 9

To meet extreme density goals, the half-height HP BL2x220c server blade includes two server nodes. Each node can support two quad-core Intel® Xeon® 5400-series processors and a slot for a mezzanine board. That equals up to 32 nodes (256 cores) per c7000 enclosure. Each c7000 enclosure contains two HP 4x QDR InfiniBand Switch Blades. Figure 8 shows how using the dual-node BL2x220c blade lets you deploy 576 nodes in half as much rack space. Figure 8.
