asked on # kVA power load of Proliant G7 & Oracle T3/M4000 servers : single & dual power input

Q1:

From the power meter on the MCB mounted the wall, when I power up one rack

that has 7 Proliant DL380 G7 servers, the power load increased by 1.2kVA for

the DC room. Due to shortage of power points, only one input per server is

connected up with power cords. Suppose I have enough power points &

connect up both power inputs on each server, will this increase the kVA power

load or it will still be the same 1.2kVA total load for the that entire rack?

Q2:

Does anyone has any estimation of kVA power load per Oracle Sparc T3 server

(populated with 4 SCSI HDDs & 32GB RAM& both power inputs connected) ?

These are new servers which will be coming in but I need to do some planning

Q3:

Same question as Q2 above but for Oracle M4000 server

Link above gave Dl380 G7 at 439 Watts :

> The DL385 G7 recorded an average power consumption of 463.3 Watts,

> compared to 438.5 Watts in the DL380 G7

What I need to know next is whether my assumption that if a server has 2 times

the Watts of another server, does this mean the kVA would be double as well?

For the purposes of your calculations, kVA = kW or 1 Watt = 1VA. VA is used for AC where current may lead or follow voltage.

ok

Thanks! Glad I could help.

Thanks.

proliant G7 is about 280 Watts

T3-2 with 4 HDDs & 32GB RAM works out to about 800 Watts

(sample power)

M4000 with 2x 300GB HDDs and 16x 8GB RAM works out to 1038 Watts

(sample power)

So can I say the kVA of T3-2 would be 2.86 times of DL380 G7

& M4000 wud be 3.7 time the kVA of G7?
