How to calculate maximum power needed

[ReynierPM]

Hi every:
I will buy a new EVA4400 2C4D with 4 HDD 600GB 6G 15k FC disks per enclosure. I need also buy some backup solutions, thinking in APC, but first need to know how I can calculate the power needed for this configuration plus maybe 25% more planning some upgrades at future. I found in tech specs that for 2C4D with fully populated enclosures with 450GB FC 15k dish and embedded switches the power consuptiom is 1209W but I'm not so sure if this is the correct value for estimate the backups. Can any help me?

Have you used the Excel sheet in this doc?

Ok very good +10, but I have some more questions. The tools calculate two values: Redundant and Failover and also Total Calculated Power Consumption and Total System BTU/hr. As far as I know Power Consumption is for energy needed and BTU is associated to ventilation meaning air conditioning or I'm wrong?
Cheers
