Day 3/ Session
Creating energy-efficient IT infrastructure
The ingredients necessary to create energy-efficient IT infrastructure
as Sandeep Nair, president, Emerson Network Power India Pvt. Ltd., pointed
out is to measure, manage and optimize
 Nair
maintained that it is critical for the CIOs to take an energy logic approach
while using measures, aperture VISTA for managing and introduce enterprise level
solution to the network closets for branch offices which can optimize IT infrastructure.
Given the changing roles of the CIOs and CTOs from a traditional technology
provider of IT infrastructure, automation etc., to an evolving role to be a
business strategy enabler having a competitive edge, value creator, it is imperative
to make a difference in this world.
Nair opined that there have been value drivers with changing thought paradigms
and this calls for creating an energy efficiency data centre. “It is critical
for the CIOs to have top priority in delivering on service level agreements,
increase performance with adequate compute capacity, ensure reliability creating
redundancy at all levels and having the ability to support along with good security,
“said Nair.
Energy logic is one of the methods that Nair suggested to reduce data centre
energy consumption. It is ideal to start with sequential road map that starts
with IT equipment and moves to support IT infrastructure with emphasis on cascade
of savings. From ideal data centre energy consumption model perspective Nair
stated that computing equipment would be 52%, while the power and cooling ratio
would be 48%. Nair reiterated that the cascading effect would have greater impact
where 1 Watt saved at the server component level results in cumulative saving
of about 2.84 watts in total consumption. He recommends 10 strategies which
could help CIOs in achieving the desired effect which includes use of low power
processor, high-efficiency power supplies, follow server power management, use
of blade servers with comparison of hardware, server virtualization, effective
power distribution architecture, implement cooling best practices like improve
vapor barrier, unnecessary humidification or dehumidification, reduce solar
heat gain and so on. The other strategies would include the use of variable
capacity cooling, high-density supplemental cooling, monitoring and optimization.
According to Nair it is critical to identify and disconnect ‘Ghost servers’,
consolidate storage from direct attached storage to NAS etc.
Another feature is that optimization frees up average 65% space from 463 sq.
mts., to 164sq.mts. Nair firmly believes that driving green initiatives, right
sizing of infrastructure resources, proactive manage capacity, bringing in operational
improvements, bringing enterprise level visibility with management tools into
the network would drive energy efficiency along with robust monitoring systems
such as video surveillance and control and GPRS modems and others.
