Greening Your
Information Systems
Selecting Metrics
• Power Usage Effectiveness and Datacenter Efficiency.
• Two metrics have recently been introduced that help
measure data center efficiency: Power Usage
Effectiveness (PUE) and Datacenter Efficiency (DCE).
PUE is defined as
• PUE = Total facility power/IT equipment power
whereas DCE is defined as
• DCE = IT equipment power/total facility power
• Total facility power is the power as it is measured at
the meter for the datacenter. IT equipment power is
defined as the power needed to manage, process,
store, or route data within the datacenter.
• IT equipment power includes the load
associated with all the IT equipment, including
the following:
• • Computers
• • Storage
• • Network equipment
• • Switches
• • Monitors
• Total facility power means everything that is
used to support that equipment, including the
following:
• • Uninterrupted power supplies
• • PDUs
• • Batteries
• • Cooling system
• These metrics can tell you various information:
• • When you can improve your datacenter’s
operational efficiency
• • How the datacenter compares with competitors
• • If datacenter processes are improving with your
changes
• • Opportunities to repurpose energy for extra IT
equipment
• Datacenter Density: Datacenters with more rack
density and higher space utilization score higher.
• Storage Utilization: This metric compares how much
storage you are using, compared with how much you
have available to use.
• Storage Density: Comparing the amount of storage to
your datacenter’s area. This helps you determine
whether you are making the best use of your facilities.
• CPU Utilization: This measurement examines the
percentage of utilization of your servers’ CPUs. This
can be measured with a number of commercially
available performance measurement tools.
SWaP
• When considering purchasing new servers, there’s more to
consider than just overall performance. Sun Microsystems
has developed a metric that calculates such issues as floor
space and power used, along with performance. The
metric, known as Space, Watts, and Performance (SWaP),
is expressed as:
SWAP = PERFORMANCE/SPACE * POWER CONSUMPTION
• On its own, the metric doesn’t mean a lot. For instance,
let’s consider a server with the following characteristics:
• • 400 operations
• • 4 rack units
• • 300 watts
Tracking Progress
• Once you make your initial readings, it’s
important to make note of those
measurements. You can do this simply using a
tool such as Microsoft Excel and just add data
as your project progresses. However, other
tools are available that you can use.
• 1. BI Tools: They give you a visual summary of the data
you want to track as well as an at-a-glance
understanding of business conditions.
• 2. Online Analytical Processing (OLAP): This feature
allows some information systems to analyze data from
different perspectives and give you the results.
• 3. Reporting software: These applications generate
aggregated views of data you are tracking.
• 4. Data mining: This allows you to go back through
your data and search for a specific piece of
information.
• Microsoft PerformancePoint
• Microsoft SQL Server
Change Business Processes
• The way you run your business also has a huge
impact on the environment in how much power
you consume and waste you generate.
• To reduce the amount of waste you generate in
the following areas:
• Worker time
• Power
• Inefficiency
• Paper
• Materials
Customer Interaction
• Your company can save a lot of time and
money by making some changes to the way it
interacts with its customers.
Customer Relationship Management
• Customer Facing Operations: face-to face
interactions, telephone calls, instant messaging,
web chats, e-mail.
• Internal Collaborative Functional Operations: IT,
billing, maintenance, planning, marketing,
finance, and manufacturing.
• External Collaboration Functions: suppliers,
vendors, distributors, lobbying groups, and trade
associations.
• Customer Advocates and Experience Designers:
These are the people and technologies that help
deliver value to the customer and profit to the
organization.
• Performance Managers and Marketing Analysts
• Customer and Employee Surveyors and Analysts
Technology
• The technological components of your CRM
system include the following:
• Database
• Customer Intelligence
• Business Modeling
• Learning and Competency Management Systems
• Analytics
• Collaboration
Paper Reduction
• SharePoint Server
• Workflow Management (scanned and save on
SAN)
Green Supply Chain
• Green Procurement: When you need to acquire products,
you can ensure you’re doing so ecologically by engaging in
green procurement.
• A good green procurement program will include these
steps:
• Get organizational support
• Conduct a self-evaluation
• Set goals
• Develop a strategy
• Run a pilot project
• Implement the plan
• Review the program
Improve Technology Infrastructure
• Reduce PCs and Servers: Virtualization (Installation)
• Thin Clients
• Rationalization : Are there any servers that you,
honestly, don’t use anymore?
• Software as a Service (SaaS)
• ASP (application service providers) Differences
• Telecommuting
• Shared Services
• Hardware Costs
• Cooling
