Need Assistance with specing a Rack Solution

Hi,

I have a situation with 14 - Power Edge 2950 III with redundant power supplies that will be fully loaded spread across two Dell 4210 racks and need some direction or help with a sizing a UPS and proper PDU setup. Based on example calcs from Racksolutions here is what I have so far:


2950 III
750W

750 + 20% = 900W
750 - 20% = 600W

900W/120VAC = 7.5A (max)
750W/120VAC = 6.25A (spec)
600W/120VAC = 5A (min)

6 Servers on 1 PDU

7.5A * 6 servers = 45A (Max Load)
6.25A * 7 servers = 43.75A (spec)
5A * 9 Servers = 45A (min)

I would like to use a fully manageable PDU like the APC switched PDUs and I forgot to include a monitor /keyboard,
1 -48 port gig switch, KVM solution (Dell), a rack fan for each rack and wiggle room for growth.

Thank you,

BTW - How accurate is the Dell Datacenter Sizing tool - the numbers seem off to me.
