PowerEdge Ampere

[Giorgio Zarrelli]

Hi,

I recentry bought 3 PowerEdge and I'm looking for a colocation in a server 
farm. The problem is that even though I need only 8 units or 1/4 of rack (11) 
units, some ISP bounds me to 2,5 Ampere. Now, if I look at the 3 server:

2950, 4 sas 15K disks, 4 gb ram, redundant power 

1950, 2 sas 10K disks, 2 gb ram, redundant power

860, 2 sas 10K disks, 1 gb ram, no redundant power

and 1

PowerConnect 2708

I see that the Ampere count is somewhat around 4,39 Ampere. 

Being in Italy, the Voltage is 220.

Is this count right? 

Do they, alltogether, require 5 ampere? That will compel me to take 1/2 a 
rack, the only size I will have 5 ampere with.

Or I should use a different method to evaluate the Ampere required?

Thank you in advance for your help.
