Green IT Expo – London 5th November

Wednesday 5th November, 2008

As founder and CTO of a small IT consultancy & Microsoft Gold partner ‘Full Circle Technology Limited – www.thefullcircle.com – I often attend trade shows and events.  On Wednesday I went along to the Green IT Expo (www.greenitexpo.co.uk) at the Barbican Center in London, and made a few scribbles from the day…

“Gartner predicts that Green IT will be the No.1 Strategic Technology for 2008, accelerating and expanding the focus that came to the forefront in 2007.”

I had some very interesting conversations with various vendors and attendees on various things Green IT related, and some not so… I also attended some very interesting seminars, these stood out for me:
 
Virtualisation as an IT Optimiser

Hosted by Tikiri Wanduragala, Modular Systems Senior Consultant, IBM

Today’s enterprises are confronted by a rapidly growing stream of disruptive forces, e.g. globalisation, mobile devices, new collaboration models, energy management and emerging economies. At the same time, information technology is rapidly expanding to make many new applications economically viable. However, the cost of managing IT has doubled since 2000, putting the datacentre at risk. As corporations intensify their focus on delivering innovation and globally integrating their business design, pressure to improve datacentre efficiency and agility will continue to grow.

Virtualisation, the de-coupling of resources from the physical environment, offers a solution through greatly improved resource management and will render non-virtualised IT obsolete over the next 3-5 years. Successful organisations will make virtualisation an essential part of their data centre optimisation plans. IBM will outline four specific actions you can take now to help improve efficiency and agility through virtualisation.

x86 systems are the driver, simply because of the numbers involved.

25 new x86 servers coming on-line every minute and they are switched on 24×7!

A play station has 8 cores, more powerful than most x86 servers!
Why? Because we all demand faster, quicker, shorter…

Centralised computing is back in as opposed to the 80’s-90’s distributed dream

Server consolidation is just the start, the desktop will happen, further centralisation.

If you virtualize you have to do the lot! I/O and storage, otherwise you loose the resilience benefits

Start thinking about servers or desktops as a file then the architecture changes accordingly

Virtualization 1.0
test & dev
slower than the real thing

Virtualization 2.0
business continuity – HA / DR
performance improvements – load balancing, resource streamlining, etc

Virtualization will drive architectural advancement – servers no longer being 10% utilised, but 80%+ utilised, however…

Your eggs will be in one basket, so it had better be a good basket!

Think Different! 😉

Virtualization enables consolidation, the more you consolidate the better the returns!

Management needs to be strong – people, process and technology

High Availability is critical!

Virtualization introduces standardization and therefore allows repeatable, scriptable systems management, deployment, etc.

However, if you do it badly it is a rope to hang yourself, and it will be a much swifter end!

Akin to moving from a relationship to a marraige!

 

Why Green IT & Virtualisation Should be Top of the Financial Director’s Agenda
Hosted by Adam Ryan, Strategic Services Director, Ben Stollard, Director of Consultancy Practise, VirtualizeIT

GreenIT and Virtualisation have become the latest IT buzzwords and every product or service is clamouring to establish its green credentials, VirtualizeIT will cut through the hyperbole to illustrate that the green revolution utilising Virtualisation is actually saving organisations hundreds of thousands of pounds whilst also enabling greater corporate environmental responsibility.

Cost benefits of server virtualization

Finance sector led the way

Ave IT spend 2.3% of turnover unlikely to change (costs per user relatively unchanged) – Gartner

VDI objection – reduction in local processing power is least popular…

Perception of utlisation is much higher than the reality!

No other company asset would be tolerated that is only used 3% of the time!

Industry ave for server utilisation is less than 9%

AIB had 450+ servers and haven’t bought a new server in 18months, now 43 servers but could be halfed although now fully FT DR capability with c.20 servers split across 2 DC’s

49 x DL380 c. 465w to 6 x IBM virtualized env. Saving £39K PA

The change has to be seamless – changing the engines of an airliner in flight analogy

Use your D/R estate also for test & dev to ensure utilisation numbers

Making a compelling investment case

Consultancy costs to virtualized…
S/W isn’t the main cost!

MS reckon on 10m virtual servers in the market within 18 months

Desktop revenue is falling! The move back to centralised computing is underway

VDI provides great opportunity for security enhancements

Difficult to justify on a basic utility an hardware cost is difficult, the management costs is where it’s at.

Although economies of scale factors – larger the estate, greater the returns
