Next Green Data Center component - Network Infrastructures

Cisco has added their Green Guru.

Next ITWeek writes about the need for Network Infrastructures to go Green.

But even as IT managers contemplate the case for energy-efficient data centres, some analysts believe that a similar green revolution is about to hit firms’ network infrastructures. Jon Collins, service director at analyst firm Freeform Dynamics, is one of them.

“The network doesn’t have the best track record when it comes to being green. This is ironic, given that it is an area of great potential, particularly considering the efficiency gains that could be achieved if, for example, the data was in the right place at the right time,” he says. “Network efficiency reduces risk and lowers the requirement to store multiple copies of data.”

A branch office, for example, might previously have stored all of its files locally. But using Wafs, the files can all be maintained centrally at headquarters. Utilising a mixture of traffic compression and byte-level mirroring of local data, files can be quickly mirrored between the two sites. This approach reduces not only the capital expenditure on branch office storage systems and the energy needed to run them, but also the operational expenditure and carbon emissions involved in sending out staff for local maintenance and support.

This last point on the branch office is well made.  Just 3 years ago when I was working on Microsoft's Branch Office Infrastructure Solution, we never heard about power costs in any of the considerations, and I would place bets that the Windows Server 2008 doesn't think about power costs and carbon emissions as part of their marketing material, even though Windows Server 2008 has the right features.
