resources. A key component of this is the next-generation HP ProLiant servers with the ProActive Insight architecture and its technologies for automated energy optimization. These technologies reduce the power and airflow needed to operate ProLiant Gen8 servers, enabling you to reclaim limited space - HP ProLiant DL320e | HP Common Slot power supply technology, 3rd edition - Page 3
platforms with a Common Slot power supply bay (Figure 1). HP Common Slot power supplies are compatible with over 90% of HP ProLiant G6 and G7/Gen 8 servers, as well as with select HP Integrity and HP storage systems. 1 DC-DC power supplies such as the HP 1200-W CS 48-VDC power supply do not receive - HP ProLiant DL320e | HP Common Slot power supply technology, 3rd edition - Page 4

Load Balanced and High Efficiency Modes An HP ProLiant server configured with the HP 460-watt, 750-watt, or 1200-watt CS power supply supports the following three scenarios: A: Operating with a single supply B: Operating with redundant supplies in Load Balanced Mode C: Operating with redundant - HP ProLiant DL320e | HP Common Slot power supply technology, 3rd edition - Page 8
4 shows a typical screen from a Power Advisor calculation for a ProLiant DL380p Gen8 server. The Power Advisor allows the user to select precise configuration parameters such as processor type, memory size, and drives. As the configuration is being made, the Power Advisor continuously calculates the - HP ProLiant DL320e | HP Common Slot power supply technology, 3rd edition - Page 9
