Our take-outs from the latest #KNGS Green Application Hosting workshop from Jan Wiersma

Last Tuesday (May 8th) I attended a workshop around Green Application Hosting organized by the Knowledge Network Green Software (otherwise known as #KNGS).

The #KNGS shares knowledge and creates awareness of the potential of green software, thus creating a demand-driven market. The organization was founded by TNO, VU University Amsterdam, Amsterdam GreenIT, SIG along with the Dutch Government and AgentschapNL. Offering a great opportunity for EvoSwitch to further its contribution to a green, climate-neutral environment, we’re delighted to be involved.

The workshop on Tuesday featured the following three perspectives:

1. The supplier perspective: What incentives currently exist for datacenters to reduce the energy footprint of their customers’ software applications?

2. The measurement perspective: How can energy consumption in the datacenter be reliably attributed to individual software applications?

3. The billing perspective: What billing models enable application owners to benefit financially from energy-optimization?

Guest post by www.greenhost.nl : A brand new server

Last month we installed a new server. While this new hardware is great news for us nerds, some may see it as running slightly counter to our green commitment.  Our preference is to optimize all our equipment to extend the useful life of the hardware. But now it really was time for a new server.

In order to alleviate our somewhat mixed feelings about this new addition to our array of hardware, we chose to travel by electric car to the data center in order to install the equipment. Since it was launched in Amsterdam some months ago, an electric Smart car sharing scheme has become very popular among several employees of Greenhost. The driving range of an electric Smart car proved to be more than adequate for a return trip to Haarlem

The server, which just about fit in the trunk, is an IBM X3550 M3 server with 144GB memory and 8 CPU cores. These types of machine

are used for our virtualization layer and form the basic building blocks of our network. The machines are fitted with an in-memory file system for the virtualization software, thereby doing away with the need for hard disks (and yielding additional energy savings). The virtual machines (with SAN or NAS storage) that will run on this hardware will eventually be responsible for hosting websites, databases or e-mail.

We opted for IBM systems due to their low energy usage and the minimal amount of heavy metals and other toxic substances in their hardware. Additionally, IBM is a class A brand and supplies ultra-reliable hardware.

Jan Wiersma’s round-up from this year’s IMN / Data Centres Forum conference

At this year’s IMN Financing, Investing & Real Estate Development for Data Centres Forum, I joined the brilliant Jean-Simon Venne, Vice President-Energy Efficiency, SMi-Enerpro, to discuss datacenter design, implementation and construction. Our session on Day 1, combined with the Green Data Centres, Data Centre Energy Efficiency and ROI/Payback debate, saw many great and discerning arguments raised.

One discussion I was particularly involved in was around the idea that clients aren’t asking for modular and ‘green’ approaches from real estate giants. My counterpoint to this argument was that without utilising the modular approach, clients potentially miss the great CAPEX opportunity that this typically offers. Equally, from an OPEX perspective, the modular benefits of free cooling and reduced temperatures are unexploited. It is therefore the responsibility of the datacenter industry to educate customers on these issues as they often fall under the radar of many CIOs and CFOs, which is therefore the reason many businesses don’t opt for them.
