“Virtualisation is currently the ultimate remedy for CIOs who are faced with growth challenges, compute power utilization issues and data centre utilization problems.”

Virtualisation is the key mantra for going green. Comment

Virtualisation – as a single most important emerging tool, virtualisation can be an enabler of  Green IT. The very purpose of virtualisation is to consolidate and utilize the hardware more  completely. And this play well into the Green IT requirements. Virtualisation is available at all levels from us. Whether it is servers, storage, networking framework or software stacks.  The objective of providing such a robust and comprehensive span of technologies is to allow customers to adapt what might be most appropriate for his environment and benefi t from that rather than force fi t a solution.

What is happening on the virtualisation front in India?

Virtualisation is currently the ultimate remedy for CIOs who are faced with growth  challenges, compute power utilization issues and data centre utilization problems. Currently,  data centres have only 20% utilisation with seven percent effi ciency and some servers don’t  get used at all. This calls for effective handling where virtualisation does the job. Apart from  acknowledging the primary advantages of virtualisation technology (like improved  management capabilities and better IT infrastructure utilisation) enterprises in India are fast  picking up on its additional benefi ts like savings in power consumption and optimized investment in physical offi ce space.

As per IDC, with the adoption of virtualisation technology, utilization rates for x86 systems  have jumped from less than 10 % to a far healthier 30 to 50 %. Analysts also report that virtualisation will rise dramatically through 2010.

What is the upcoming trend with respect to green data centres in India?

Indian Inc is already facing energy crisis. Emerging high density computer systems and  consolidation of IT resources into fewer data centers are stretching the limits of data center   capacity. The large number of components in a data center including cooling systems, power systems, and computer systems and the diversity of these components makes data center design and operations a complex task. The demand for data center solutions with lower total cost of ownership and lower complexity of management is driving the creation of next generation data centres. Large data centers are looking at pocketing more green into their pocket.

At Sun, our modular, pod-based data centres can turn on a dime whenever business directions change, from accommodating new equipment in our pods to expanding our rack footprint by deploying additional Sun Modular data centres. We can accommodate growth and increases in density because three key data centre functions — power, cooling, and cabling – are prepared from day one to support an overall doubling in each area. The pod-based design is an enabler, rather than a barrier, to business growth whether it is through an increase in demand, server  replacement, merger, acquisition, reorganization, or other business activity. Our pod-based design has the fl exibility to support gradual or rapid change to match the pace of  the engineering and IT environments at Sun.
