HP Netserver High Density Rack Solutions Overview (LP 2000r)

Power consumption worksheet - sample

The following worksheet makes it easy to make all the calculations you need to make.

Using the worksheet is simple. Inventory the HP Netservers LP 2000r that you will be rackmounting as to the number of CPUs, memory boards, HDDs and add-in cards installed and input these numbers into the “Number Installed” column. Multiply this number with the value in the “Unit Input Power (Watts)” column to get the “Total Input Power (Watts)” for this particular server section. Finally, add all the values in the “Total Input Power (Watts)” column to arrive at a total power consumption figure for the server.

Then using the formulas provided, calculate the current requirements and the BTUs/Hr.

For example: The calculations for an HP Netserver LP 2000r with 2 each 933 MHz processors, 2 GB of memory, 2 each HDDs and a NetRAID 1M controller will show the following results:
