Conclusion

The HP BladeSystem p-Class 1U power enclosure is a vital component of the HP BladeSystem infrastructure and plays an important role in helping HP customers build an adaptive enterprise. It provides cost-effective, efficient, hot-plug, redundant power for single server blade enclosure deployments. IT environments can use this solution for blade evaluation purposes, distributed server blade deployments to remote locations, and heterogeneous server blade deployments within a single rack. IT environments with deeply entrenched power distribution environments can leverage the 1U power enclosure to help accommodate existing PDU strategies. The HP BladeSystem p-Class 1U power enclosure also has backwards compatibility, allowing IT administrators at small and medium- sized businesses to leverage their previous IT investments by fitting the 1U power enclosure into existing racks in their infrastructure.
