Little Miss Enviro Geek : Server Virtualisation

Some personal news...

biwirth — Fri, 18 Sep 2009 03:24:00 GMT

Hello Dear Blog Readers,

(hmmm....that kinda sounds like the beginning of one of those SPAM emails)

I wanted to let you all know I am moving on from Microsoft and shall no longer be blogging here. I'll be moving an archive of these posts to my website http://www.greenitstrategy.com and shall continue blogging there on Green IT.

So what will I be doing now?

Well, I have decided to take some time off, write a book and maybe look into starting my own business. Regardless, you can always catch me through my website and please do feel free to visit me there.

Thank you to everyone who contacted me with their Green IT questions over the past two years and gave me feedback. I really appreciate your support and good luck with your own Green IT initiatives.

Kind Regards,

Bianca AKA Little Miss Enviro Geek

TechEd 2009 US announces Green IT Track - first ever!

biwirth — Mon, 27 Apr 2009 03:01:48 GMT

For my fellow green geeks in the US, Microsoft have announced their first ever Green IT track for TechEd 2009. Nice! There are 9 sessions specifically on Green IT, including:

ARC313 - Understanding environmental compliance, policy and regulation for IT Leaders - I have seen a version of this internally and I'd recommend it to anyone who wants to understand a bit more around how environmental management is achieved with technology.
ISB206 - What's Behind the Cloud: Microsoft's Data Center Transformation - Christian is one of the key people working with The Green Grid from Microsoft on Data Centres.
MGT201 - Microsoft System Center for the Datacenter
VIR206 - Virtualization for Sustainable Computing
WSV203 - Saving Power and Reducing Environmental Impact with Windows Server
WSV309 - Enhanced Power Efficiency and Power Management Capabilities in Windows Server 2008 R2 - this one should be very informative. Stephen Berard is THE man for power management in Microsoft.

New Microsoft Services for Green IT

biwirth — Wed, 25 Mar 2009 23:05:24 GMT

I had been speaking with a couple of the local Microsoft Consulting guys recently about their endeavours to setup services around Green IT, and then found globally we already offer a couple of services in this space:

Microsoft Architecture & Planning Services - focus on reducing costs, increasing IT control & management and reducing environmental impact through the development of a Sustainable Technology Roadmap, and assessment of server consolidation, desktop efficiency, business intelligence capability and unified communications. Check out the brochure HERE.
Sustainable IT Briefing - wherever there is a Microsoft Technology Center (MTC) there is a team who can run a one-day briefing workshop covering areas such as: how Windows technologies provide built-in energy efficiency, how to optimise resources using System Center & Virtualisation technologies, identification of opportunities to reduce carbon through unified communications, how BI can provide a platform for sustainability performance management, and how Software + Services can provide workload transference opportunities. The complete brochure is HERE.

If you are based in Australia, we don't have an MTC unfortunately however there are a couple of us here (including me) who can run a Green IT session for you as part of an Executive Briefing in our Sydney-based Executive Briefing Centre (EBC). If you are interested in this, contact your local Account Manager and ask them if you can setup an executive briefing with Green IT as one of the topics (there are lots of other topics we can cover in these types of sessions as well - we have a catalogue to choose from).

Also, a quickun' today: Microsoft Australia has recently launched their Environment site - check it out at www.microsoft.com/australia/environment.

Great new whitepaper: Power In, Dollars Out: How to Stem the Flow in the Data Center

biwirth — Wed, 07 Jan 2009 05:11:47 GMT

First up - Happy New Year! :) I had a relaxing time (apart from the stupid oven cracking it halfway through the roast on Xmas day) and, when the mood struck me, I spent time updating my website with new features and content.

Back into the swing, in early December the Windows Server Performance <guys/girls/whatever> released a great new whitepaper with quite a lot of detail around optimisation of servers, as well as publishing their test results.

Some of the best practices covered include:

Shut down idle machines during off-peak times.
Opt for 2.5-inch instead of 3.5-inch disk drives.
Use low-revolutions-per-minute (RPM) disk drives where it is possible.
Select power-efficient processors and memory.
Install variable-speed fans and efficient power supplies in servers to reduce waste.
Use remote-controlled power strips to completely eliminate electricity flow to "powered-off" servers.
Ensure that Windows Server 2008 is configured to use the Balanced power policy.
Tune processor power management parameters to increase efficiency by up to 10 percent.
Consolidate workloads or combine server roles on idle and underutilized servers where it is possible.
Turn off hardware-based power management
Deploy the latest service packs and Windows Server releases.
Remove or shut down unnecessary roles, applications, and devices.

The 'shut down idle machines during off-peak times' section references a good article by Dave Ohara which provides some more practical suggestions for how you actually achieve this. However I do question the viability of turning off servers when they are not in use in **some** environments:

Issue number 1: I know that some of my customers have trouble even identifying what applications are running on certain servers and what the subsequent business impact would be if there were turned off. This sounds highly unlikely and slightly dark ages to some IT departments but I know from talking to others this is the case, especially on older hardware and OS' that 'just keep running in the corner'. This is not to say I condone not knowing what servers do - just pointing out that turning off idle machines is a more complex analysis process upfront for some.
Issue number 2: in regards to actually identifying some servers that don't need to be running at certain times of the day - I think this may be a nirvana situation in some less-than-leading-edge environments. Probably the 'easier-target' scenario I could see this working in is where you have a bank of servers, which Dave rightly points out - something like a Citrix farm in which each server may generally be configured identically and en masse (which would provide capability even at reduced performance until a new server(s) came up from being turned off, if that was necessary).

The whitepaper starts to get really meaty towards the middle of the document, covering some great detail on areas such as efficiency analysis, ACPI (C-States, P-States, T-States), interrupts, timers and test results for removing components to measure their power draw. A few good points:

Even when powered off, the test server consumed 27 watts - you might often hear a similar story along the lines of 'unplug your mobile phone because it draws power even when turned off at the point but is still plugged in'.
In the tests Memory consumed 54% of the total system power. Newer RAM consumes less power due to modern energy efficiencies.
Using 2.5" disks instead of 3.5" disks doesn't impact performance but does consume 50% less power.

Anyway before I give away the storyline, I'll let you go read the paper yourself: http://www.microsoft.com/whdc/system/pnppwr/powermgmt/Svr_Pwr_ITAdmin.mspx

Also check out a related blog post by the team who wrote this whitepaper, focusing on tuning power processor performance: http://blogs.technet.com/winserverperformance/.

Hyper-Green: Calculate your energy & consolidation savings...now this is cool!

biwirth — Fri, 21 Nov 2008 09:43:30 GMT

I got a message this afternoon from our Windows Server and Infrastructure Product Manager with a hyperlink and a message: "Not sure if you have seen this but it is cool!" And I have to agree! We have released a new web site to help you calculate the energy / consolidation / carbon savings for your virtualisation business case...its called "Hyper-Green" - http://www.hyper-green.com/

Simply enter the number of servers; then move the dial to your estimated consolidation figure - in this case I chose 50% - which takes me down to 25 servers in total:

The click on Create a Virtualization Report to modify further details like:

Company Name
Country
Your average electricity cost per kWh

Click Update Report; then when you are ready, click Save Report.

Tick box the appropriate boxes on the next page indicating what products you already have in your environment and what the key business/IT drivers are:

Click Get Report and More. You'll then get the opportunity to email the report:

Be sure to check out the links to the Microsoft Virtualization ROI tool on the last page: this provides a really excellent model for calculating the details around ROI and business benefits. We use this inside Microsoft when we are helping customers prepare to put forward a business case for virtualisation:

And the Microsoft Assessment and Planning Toolkit will help you get a good understanding of how and what to virtualise in your existing environment.

Have fun! :)

Get the Facts on Green IT

biwirth — Wed, 05 Nov 2008 20:36:58 GMT

I thought while I was sitting here in my pyjamas eating breakfast this morning I'd post a little facts blog (yes I have no life - or rather my life is so full of stuff I don't have time to blog any other time - so in pyjamas it is). Below are the top 5 facts per topic area - this great list was recently put together by our E&S team in corp...

The Products:

1. Windows Vista: According to the Natural Resources Defense Council (NRDC) customers can save about $50 each year for every desktop computer equipped with the new software. Used widely, new power management tools in the Vista operating system could shave $500 million off the nation's energy bill and eliminate 3 million tons of global warming pollution.

2. Windows Server 2008: 10% more efficient on the same workload than previous versions

3. Virtualization: Virtualization can reduce energy use by up to 90%

4. Unified Communications: According to Forrester, UC can reduce travel from 10-30%

5. MS Data Centers: current data centers are 50% more efficient than those built 3 years ago.

Microsoft themselves:

1. Commuting: With this expansion of the Connectors, estimates suggest that Microsoft will eliminate annually 6,730,020 employee car miles and 6,387,550 pounds (or 3,194 tons) of carbon emissions.

2. Microsoft reduced its waste by 50% by moving to compostables. Microsoft becomes first US corporate campus to achieve Green Restaurant Certification for its cafeterias

3. New Microsoft buildings consume greater than 20 percent less energy than existing traditional buildings

4. Through the Microsoft Authorized Refurbisher programs, Microsoft provides low-cost software licenses to help extend the life of over 500,000 computers per year

5. Microsoft is a board member of Climate Savers Computing Initiative along with World Wildlife Fund, Intel, Hewlett-Packard and other software and IT companies, is committed to reducing the IT industry's carbon footprint by over 50 million tons a year

Our Customers:

1. Volvo: "Volvo IT estimates that just the Microsoft collaboration products alone save enough travel to eliminate 900 tons of carbon-dioxide emissions per month, and use of those tools is gradually increasing.

2. Continental: saved $65/PC/Year or 2Milliion a year by deploying vista with System Center

3. City of Porto: the city saved 504 reams of paper (11 trees per year) by moving their paper based cabinet meetings online.

4. The City of Miami can "expect to save $80,000 in power costs in the first year, with that number increasing to $190,000 by year four. Not only will this save us money, but it also will enable the city to do its part to reduce the impact on the environment-with the resulting power savings equivalent to a 355-ton reduction in carbon dioxide emissions in the first year alone."

5. Kentucky Department of Education: Reduce its physical server holdings by 60 percent (approximately 120 servers); Reduce data center space by 50 percent ;Reduce power usage by 25 percent

The Market:

1. The overall market for green IT services will peak at $4.8 billion in 2013, according to a new Forrester report, The Dawn of Green IT Services. It's a $500 million market for 2008, InfoWorld reports, but Forrester expects that spending on green IT services among enterprise users will grow by 60 percent annually over the next five years.

2. Servers typically run at far below their capacity and on average only utilize 5 to 15 percent of the actual CPU capabilities

3. A recent PC Pro Labs study, showed that 25% leave their computers running all weekend and 65% running a screen saver rather than sleep.

4. Energy costs are expected to be over 50% of an IT budget for a typical data center

5. According to The Climate Group in their Smart 2020 report, transformation in the way people and businesses use technology could reduce annual man-made global emissions by 15% by 2020 and deliver energy efficiency savings to global businesses of over $800 billion.
