Green IT was in the limelight throughout this year, with vendors falling over
each other to make themselves seen as providing energy-efficient products and
services. CIOs remained skeptical about the technology for a while, but it seems
that the chord has finally stuck and they're beginning to understand its
importance and how it makes business sense for them to go green. We discuss some
of the green technologies and products and the road map for the future.
Basically, it's not just hardware servers and blades that have gone green and are consuming lesser power. There is a lot of other equipment
as well with greener versions. Better power efficiency along with less harmful
elements in the body of the device (paint, metal, wires, etc) is what primarily
constitutes green stuff and this year a lot of such products were released-from
network switches to hard disks and even processors; all of them have greener
versions. Even LCD monitors are becoming smarter. At CyberMedia Labs, we
received an LCD monitor from Viewsonic which automatically adjusts its
brightness when the user goes to a web page with a black background. This saves
energy as the monitor needs less power to display black or darker images.
Another emerging trend is that of building new products around green
technologies. For eg, virtualization, which is probably the most used green
technology today. Now virtualization is making its way into even network
switches. Cisco recently launched the Nexus 1000V switch, which it likes to call
a pure software switch. It has been developed in collaboration with VMware.It
uses NIV(Network Interface Virtualization), which is a new networking protocol
for virtual machines that allows Cisco VN-link technology to be used at hardware
level. This allows virtual machines to be tightly coupled with storage and
network services, as a result any changes to an environment is communicated to
other. Suppose if you move a Virtual Machine from one physical server to
another, then the Cisco VN link ensures that the profile attached to this VM is
also moved.
A few measures to go green |
If going green has been on your cards for some time, then here are a few points to begin your journey:

Another trend worth mentioning is the adoption of Blade servers. These
servers help in saving energy and e-waste and let you increase the density of
your data center manifold. A single 7U blade chassis can take up to 14 blades
which saves real estate space and reduce ambient cooling requirements (as you
can host your data center in a smaller space). Blade servers are generally built
with specialized processors that consume less electricity. In Intel's lexicon,
these processors are called LV (low voltage) processors and their performance
per Watt is higher than others. However, they are not the top performers of the
lot.
PUE and DCE Metrics | |
Have you ever wondered or tried to calculate how your data center fares in terms of energy efficiency ? PUE (Power Usage Effectiveness) and DCIE (Data Center infrastructure center. While IT equipment Power means power consumed by the IT |
Nowthe trend we are witnessing is green storage. Initially it started with
SSD drives which consumed lesser power to hard drives which would turn the
spindle off or on to reduce power consumption. Now even SAS storage is going
green. Voted as the Green storage product of the year by storage Industry Awards
2008 for its multiple levels of energy efficiency, "SASBoy" is a high-density,
Serial Attached SCSI (SAS) storage solution. It uses high-performance RAID
controllers and provides fast I/O response for searching. Its vendor Nexsan
technologies claims it can provide Up to 50,000 random IOPS from cache. It
supports both iSCSI and Fibre Channel connectivity. It uses AutoMAID (Automatic
Massive Array of Idle Disks) technology, to reduce energy usage without
compromising application performance. More details about this product can be

Green mobile phones
Cell phones contribute significantly towards e-waste, and there are hardly any
campaigns(especially India) by mobile phone manufacturers about how to properly
dispose of mobile phones. In the coming year we are likely to see more and more
eco-friendly mobile phones. Earlier this year Nokia came up with its environment
friendly phone, 3110 Evolve. This mobile phone has bio-covers which are made
from 50% renewable material. Also it came in a small package which again was
made with 60% recycled content and it also has an energy efficient charger which
according to Nokia consumes 94% less energy than the Energy Star requirements.
Other vendors are also coming up with environment friendly cell phones, Samsung
has launched two eco-friendly phones this year, Samsung F268 and W510. These
phones use bio plastic which is made from materials extracted from corns. Also
Samsung F268 comes with an alarm function which alerts users to unplug their
charger after the phone is fully charged.
Nokia recently also showcased its Eco Sensor concept mobile phone. This phone
has a wearable sensor unit, which can analyze your health and environment, and
weather conditions around you. It can be worn on wrist or neck strap which is
made from solar cells. You can check out the concept phone at www.nokia.com/A4707477.
