Data Centers Are All Around You
Data Center Type Size of DC
Square
Feet
US
Count
Closet < 100 1.6m
Room < 1,000 1.3m
Localized DC < 5,000 70k
Mid-tier DC < 20,000 10k
Enterprise DC > 20,000 7k

– Over 3 Million Data
Centers in the US
– Using 1.5-2.5% of all US
Power
– At the current rate, US
Data Centers will require
30 new power plants by
2015
Key Points:
• Number of data centers by size in the US
• Customers will have several data centers
• We are targeting the Mid-Enterprise; bleeds into Enterprise
• Our target represents ~ $6 to 7B market
1.IDCs defines data centers by TYPE and forecasts the number of each in the
US (per WW Data Center Forecast)
2.Annual Contract Value (ACV) is derived by calculating the number of racks
and applying our per rack price (our price points per band)
3.Potential is ACV times the data center count
4.Our primary focus is the Mid-enterprise which captures the Localized
and Mid-Tier data centers shown
5.Target: 5K to 25K; will bleed above, but primary focus is shown

Energy (Power & Cooling) is the Fastest
Growing Expense in the Data Center
Key Points:
1.Energy – fastest growing expense in the data center (Gartner)
2.One of the largest expenses in the data center
- Nearly $40B will be spent on Server power and cooling this year!

Capital Costs:
Servers, Storage, Networks
Today….tools allow you to profile server utilization. Also, sensors and other
equipment allows you to understand energy or power consumption. ONLY
VIRIDITY COMBINES THE TWO TO PROVIDE “POWER UTILIZATION”
TIED TO BUSINESS PRIORITIES AND NEEDS.

“Half of organizations with mid-sized data
centers will have insufficient power in 2011”
Nemertes Study 2010

Data center operators don’t know how much
power they are using or where it’s being used
Key Point:
1.Data center Operators do NOT KNOW how much power they are using and
where it is being used
THEY DO NOT HAVE THE BASIC INFORMATION (i.e. UTILIZATION AND
POWER CONSUMPTION) TO DEAL WITH THIS CHALLENGE.

Data Centers Today
IT becoming increasingly agile & dynamic
– Servers are cheap and virtualization is making them cheaper
– Servers now have a massive dynamic power range
Facilities continue to be static
– Focus remains on gross delivery of power
– The gap between power consumption (IT) and power
delivery (Facilities) is growing unabated
Results
– Risk of brownouts
– Underutilized servers wasting energy, space & cooling
– Inability to deploy additional applications to grow business
7
Key Points:
1.Why a hot issue now?
-- $$$ (discussed previously) – fastest growing expense in the data center
-- Huge expense $$$B worldwide for servers alone
-- Running out of power
2.. How did we get here?
-- Demand for IT continues to grow at a rate of >35% or more annually forcing
IT to become AGILE
-- Facilities typically owns delivery of power and has not changed
-- Resulting in an organizational GAP
3.The Business Suffers…

Most of the Power is in Servers
Key Points:
1.Energy – fastest growing expense in the data center (Gartner)
2.One of the largest expenses in the data center
- Nearly $40B will be spent on Server power and cooling this year!

Incredible Dynamic Range
Servers
– Utilization Today
– Getting more dynamic
– Average utilization still
low (~6%)
– Most of IT power is in
servers (75%)
– Application Mobility
Storage
– Spin-down or Slow-
down technology
– Block-based tiers,
SSD, dynamic
migration

What Has To Happen
CIO Must Have The Power Budget
– Only the IT Staff can have the impact on power that is required to
control power
– No one will change if they aren’t incentivized to do so
10
Key Points:
IT to become AGILE
10

What Has To Happen
control power
Power Measurements At The Equipment Level
– Power at the room or rack level is irrelevant, and can’t be connected
to the business service level agreements
– You can’t improve things you don’t measure

Key Points:
IT to become AGILE

What Has To Happen
control power
Power Measurements At The Equipment Level
– Power at the room or rack level is irrelevant, and can’t be connected
to the business service level agreements
– You can’t improve things you don’t measure
Power must be tracked by Utilization
– The incredibly dynamic range of power, and the workload mobility
require power to be measured at the utilization level
– Predictive analysis can not be done without understanding the
connection between utilization and power
12
Key Points:
IT to become AGILE
12

– Connects equipment utilization and business
value to power consumption
– Deploys in minutes, not weeks
 No additional hardware required
 No server agents required
– Time-to-value in hours, not months
13
The Leader in Energy
Resource Management
Key Points: Truly Unique Capabilities…
1.Only company to offer utilization AND consumption
[Today….tools allow you to profile server utilization. Also, sensors and other
TIED TO BUSINESS PRIORITIES AND NEEDS.]
2. Quickly deployed, NOT invasive. All other alternatives are complex,
requiring Professional Services to deloy.
3. Actionable information within hours of beginning deployment
