WHAT IS “GREEN IT(
)”
COMPUTING
 refers to environmentally sustainable computing or IT
 set of processes and approaches designed to make datacentre's more
efficient
 This means reducing the power and cooling required.
 Reduce energy costs by 80%.
 Power down servers without affecting applications or users
 Green your datacentre while decreasing costs and improving service
levels
WHAT IS
VIRTUALIZATION ?
(VMWARE)
Virtualization is the creation of a virtual (rather than actual)
version of something, such as an
•
operating system,
•
a server
•
a storage device
•
network resources.
WHAT DOES THIS HAVE TO DO WITH
VIRTUALIZATION?
 For example, many of the suppliers of management software for virtualized
environments have the ability to move workloads to a smaller number of servers
when workload and service level agreements allow it. Then the unused servers can
be powered down.
 Features and Benefits
 The key benefits of virtual machine technology:
 Isolation (One of the key reasons to employ virtualization is to
isolate applications from each other)
 Standardization
 Consolidation (Consolidation of servers results in easier management and decreased
hardware costs)
 Ease of testing(Most virtual machine software today provides snapshot and rollback
capabilities)
 Mobility (Virtual machines are easy to move between physical machines)
POWER MANAGEMENT ?
Is a feature of some electrical appliances, especially copiers,
•
computers and computer peripherals such as
•
monitors
•
printers,
•
that turns off the power or switches the system to a low-power state when inactive
POWER MANAGEMENT
 Features and Benefits
 Reduce overall energy consumption
 Prolong battery life for portable and embedded systems
 Reduce cooling requirements
 Reduce noise.
 Reduce operating costs for energy and cooling.
 Using Group Policy to Enforce Power Settings
 (The power management policies are located in Power Management, under
Computer Configuration | Administrative Templates | System | Power Management.
Note that there are no power management policies under User Configuration in
Windows Vista.)
PROS AND CONS
CONS
PROS
 increased worker satisfaction
 reduction of greenhouse gas
emissions related to travel
 increased profit margins as a
result of lower overhead costs
for office space, heat, lighting
 Security
 Availability
 Complexity software config
 Skills /staff documentation
