Watts Wrong?

From Wikipedia, the free encyclopedia

The watt (symbol: W) is the SI derived unit of power, equal to one joule of energy per second. A human climbing a flight of stairs is doing work at the rate of about 200watts. A first class athlete can work at 375watts for 30 minutes before exhaustion. An automobile engine produces mechanical energy at a rate of 25,000 watts (approximately 30 horsepower) while cruising. A typical household incandescent light bulb uses electrical energy at a rate of 40 to 100 watts, while the energy-saving compact fluorescent lights which are replacing them use 8 to 20 watts to yield the same light output.

Webster's Dictionary defines a watt as "a unit of power or the amount of energy per unit of time." Last year you used 2,575,440 of them.

Webster goes on to define a kilowatt hour as "the amount of energy expended by a one-kilowatt device over the course of one hour."

Let's assume 1470 kilowatt power consumption per server on a standard Dell 200-240V PowerEdge 6850 power supply that supports your datacentre of 200 servers.

Last year you used:

200*1470/1000*24*365=2,575,440kWh

Your local power company defines a kilowatt hour as £0.05.

Well, last year your electric bill totalled: 2,575,440*0.05, which translates to £128,772.00!

Additionally, 1 kW is also equal to 3414 BTUs.

So, let's see,

That means at 3414 X 2,575,440 carry the one, you created 8,792,552,160 BTUs last year. Since the average Leibert AC system counteracts heat at a rate of 600,000 BTU/hour (at an average consumption of another 14,654 kilowatt hours to counteract the heat that you are generating with the kilowatts you have already consumed), you used an additional £733.00 of kilowatts to run the A/C system. You did this so the 200 servers in your data centre (at an average cost of £2000 each - you know the ones using all the kilowatts and creating all the BTUs) don't melt down.

So...

This means that last year your company spent £129,505.00 on energy alone to operate 200 systems that on average use 5 percent of their available resources. But as we all know, each application needs it own server, each department needs its own apps and you need a bigger budget every year!

Watts wrong with that?

Isn't it time you got to define something?

How about you redefine your company's IT systems to be more efficient? Instead of 200 machines doing almost nothing individually, what if you consolidate servers into a proven and secure environment that allows you to finally utilize the capabilities of the hardware it runs on?

How about you turn 200 systems at 5% into 50 systems, each running at 60% to 70% with each one able to integrate into a pool of resources available for any application that needs it?

How about you define next year by saving £90,000.00 on power?

How about you then tell Webster's and your local power company Watts wrong?

Consolidation is not only real; it's efficient, effective, and successfully deployed in more places than you may think.

A server consolidation project allows your company to:

• Remove unnecessary hardware and recover a lot of datacentre real estate.
• Decrease your server deployment and implementation time to hours rather than days or weeks.
• Maintain your current level of operating system and application isolation.
• Decrease the costs associated with rolling out new applications and new server instances.
• Add new applications and services without adding new hardware and infrastructure.
• Utilize your power, equipment, rack space and ultimately your budget more efficiently.
