Since the ProLiant DL160 G6 accommodates only one power supply, power redundancy will have to be provided upstream of the server's single AC connection. Figure 10 shows a rack-level power redundancy scheme using an uninterruptable power supply (UPS). With four 7-outlet PDUs and a total input current capability of 5000 VA, the HP R5500 UPS would be a good fit and would provide adequate VA and outlet headroom for server expansion or peripheral devices. Using the Power Advisor calculations indicated in Figures 8 and 9, the total heat produced by 24 servers would be 12785.28 BTU/hr., an amount that can be cooled using conventional means in most data center environments.

By using row-level power redundancy and consolidating server management with a remote console, users can achieve a maximum density configuration (42 DL160 servers). 12
