Life Cycle Management

By rickey.everhartsr ·
I have just been given the task of defining the End Of Life Cycle related to Intel hardware & Microsoft OS for my company. Can someone point me in the direction os papers already created that I can review to give me a starting point?

As far as hardware goes, drives are the most likely point of failure.
Most of the other hardware will work longer than you can find software that will run on it.

The need to update application software or Windows is the biggest factor in the functional life of PC hardware.

As to Microsoft OS's, that becomes a philosophical issue.

3 basic schools of thought:

Run it till the PC dies.

Run it until Microsoft drops the OS from product support.

Replace it as soon as Microsoft places the OS version in the extended support phase.

Here is a link to Microsoft's Product life-cycle page:

Of the 3 choices, it somewhat depends on how the PC is used.

We are running MS-DOS 5 and Windows 95 on some PCs as they have custom applications on them that would be too expensive to rewrite for a newer version of Windows.

For regular desktop use, we are switching from Windows 2000 to Windows XP.

IMHO, for networked PCs with external connections, you need to run a fully supported version of Windows.
Just because Microsoft is not releasing patches for an older OS does NOT mean it is secure. It just means that the flaw is not critical enough to justify the required programming effort.

If you read all the details on many of the patches for Windows, the flaw is critical for current versions, but not for older versions?!
For many of these issues, the hole exists in the older version too!

Well, this webinar has some very pertinant information in regards to both Intel and Microsoft. It might not be the sole resource you are looking for, but I have used it for the same purpose and it contains an ample amount of numeric justification and insight into determining the optimum lifecycle for your needs. (Don't let the title fool you. There is good information in there.)

Try not to go to far past 4-5 years if you are a small to medium sized business ..

I run 200 servers and 126 desktops/laptops..

4-5 years for all employee computers, 3-4 for Servers depending on the jobs they run.. and actually going to a Virtual Blade systems with SAN for cost savings and scalability.

Cost to maintain increases once you pass 3-4 years.. and most business write off over 3-7 years.. Now we do not replace all at once.. so it is spread out ..

Larger business that buy larger mainframe or datacenter servers may keep the systems for even longer because they are built for scalability and can go 10-20 years for hospitals, large municiple or government companies.

if your small enough keep up with the technologies..

Consider using a number of financial indices together with the technical ones you shared with us already.
1) Obviously retirement only follows sometime after depreciation.
2) What is your annual costs of ownership on the specific category of equipment? See for guidelines on TCO, but once again the answer is clear, i.e. as soon as ownership costs increase beyond an acceptable benchmark, retirement becomes an alternative option.
3) Consider cost of money for replaced equipment versus saving on operational expenses for maintenance of ageing assets.
4) Liaise with equipment leasing company and assess their retirement strategies, but remember to discount their profit motive.
