Windows 7 Deployment Best Practices - Page 2

Best Practices

 

The most compelling justification, from a financial standpoint, to rolling out Windows 7 this year is extending the life of existing hardware up to four additional years. Against the avoided hardware cost, the cost of the OS and deployment services appears trivial. Be aware, however, that system memory needs to be assured on any system built before 2008 because both Windows Vista and Windows 7 use memory heavily. If the memory is faulty or mismatched, intermittent and hard-to-diagnose failures will result. After 2008, the vendors put in practices that better tested system memory before shipment.

 

Big Bang deployments continue to work better because everyone is put on the same software platforms and support is better able to deal with any problems consistently. However, Windows 7 interoperates well with Windows XP and phased deployments remain the most common way these CIOs plan to roll out the offering.

 

Extended trials are showcasing few problems but also showing that the benefits of putting a contained group on Windows 7 for an extended period before deployment is worth the effort. Most sites are deploying to their own IT organizations first and then six or so months later, after all problems are fully understood and most mitigated, rolling out to the rest of the company.


 

Tools

 

There are a number of Microsoft tools that companies are recommending based on their experiences. Microsoft System Center Configuration Manager is being used heavily to properly provision reimaged PCs in large numbers. This tool, which was developed with extensive feedback from IT, has proven to be a huge help in terms of matching the PC configurations to the organizations and employees they have been deployed to.

 

The Microsoft Assessment and Planning Toolkit has formed the basis for early adapter installations and been one of the primary reasons so few applications have failed after deployment or stalled deployments. This tool goes to the core of why an impressive number of CIOs seem to like Windows 7.

 

The Microsoft Desktop Optimization Pack has helped early adopting organizations to move up to two-thirds of their desktop applications to servers and off the desktop itself. hey are primarily using App-V.

 

Other Considerations

 

As companies begin to think about rolling out Windows 7, there are a number of other things that they are considering at the same time. Remote access is expensive and paying for multiple remote data plans excessively expensive. As a result, they are revising WAN access policies and starting to favor plans and phones that allow tethering.

 

Some of the firms that are significantly trying to extend aging hardware cycles are looking at employee purchase and access to some corporate resources by employee-owned machines so that individuals who feel they need something newer can purchase the solution themselves.

 

In much the same fashion, firms are looking at PC alternatives and thinking of starting trials with tablets, smartphones or smartbooks to supplement their PC products.

 

Bundled bids are being considered, given that Windows Server 2008 is often deployed in the same window to both eliminate vendor complexity and get the strongest volume discounts for both the servers and desktops.

 

Recommended Considerations

 

Based on my experience, I suggest you consider some additional items. First, if you are eliminating a vendor, make sure there are no dependencies you don't know about. One of the worst problems I ever ran into was when the CIO of a firm I was working for eliminated a vendor who also turned out to be our largest corporate customer. That was nearly a career-ending decision.

 

Look at monitors and interfaces if you are rolling out new hardware. DisplayPort is an increasing option but your existing monitors may not support it, and it isn't yet universally used.

 

In looking back at my conversations with these early deployment and trial sites, a number of things occurred to me. One is that if ROI is used consistently for purchases like this, the competency in doing ROI analysis improves and the success rate with the CFO improves as well. This deployment is a huge opportunity to rethink what actually goes on the desktop and you can use it to reduce your desktop complexity and desktop operating costs significantly.

 

Vendors should be held to the results they share with you for ROI calculations and if the sold benefits don't result, this should be taken into consideration for future business. So many deployments like this are managed tactically and often the results suffer.

 

Spend some time talking to similar firms who have already deployed Windows 7 or who are also in trials. Events like this CIO forum are a great place to meet folks like this.

 

Generally deployments like this work vastly better with new hardware and given the relatively low cost of that hardware, you may be better off with it rather than extending the life of the existing stuff. As vendors focused on cost containment several years ago, they designed for three-year life cycles. The chance of catastrophic hardware failure goes up sharply after thee years as a result.

 

Particularly in the first half of the year, Microsoft is looking for early deployment sites and will make available resources for free that can substantially reduce your cost of deployment. In addition, because you will then be visible, it will tend to go to greater lengths to keep you happy. Firms have found that invaluable in the past.

 

Make sure you have enough system memory,. Systems with less than 2 GB of memory are very slow and users will likely complain about the result. With a focus on putting applications and data on servers, consider low-capacity SSD drives over high-capacity magnetic drives. They are more reliable, dramatically faster, and help force the employee to put information on servers where it belongs.

 

Wrapping Up

 

It amazes me that I found no CIO who didn't like Windows 7 and an impressive number that seemed to actually love it. Don't be surprised that, after your testing and deployment, you actually think better of the platform and Microsoft as a result. That seems to be the outcome so far.

Excellent summary, Rob! However, I'm surprised by the interest in, and support of, deploying Windows 7 on older hardware. Surely there are more gains to be had from adding newer, faster hardware than trying to upgrade old systems just to string them along for another year or two?
