Retirement Planning for your Server
For better or worse, companies are keeping their servers
around longer. Due to tighter IT budgets and more durable and powerful hardware, companies
no longer replace servers every two years. Now, some wait as long as four or five years.
In Summary
- Businesses should base server upgrade decisions on concrete performance metrics, not
depreciation schedules.
- Creating a long-term server replacement plan reduces your odds of updating servers too
soon or too late.
- Assigning servers to new and less demanding tasks, rather than discarding them, can be
a great way to get more value from old hardware.
According to the 2005 Global Server Survey from Boston-based Yankee Group Research Inc.,
58% of organizations worldwide now retain their file servers an average of four to six years.
Companies that plan ahead and think strategically will end up making the smartest, most
cost-effective decisions about when to upgrade their server hardware.
And companies that put off a server replacement simply to save money may increase their
risk of weak performance and service outages. That can effect not only on internal network
operations but also on external relationships with business partners, suppliers and customers.
On the flip side, upgrading too soon pointless and costly.
The best approach to setting server replacement cycles is to base your decisions on concrete
network performance data and careful forecasts of your future needs. Approaching server upgrades
methodically is the only way to know for sure whether new hardware will cost you more than
it saves, or save you more than it costs.
Take Performance Data Into Account
There are few rules for when businesses should replace their servers, but, one thing experts
agree on is that waiting longer than five years is usually a mistake. The percentage of servers
experiencing some form of component failure jumps from 10% in year four to 50% in year five,
according to James Browning, a research vice president at IT analyst firm Gartner Inc. in
Stamford, CT. Additionally, service contracts often expire at the 3 or 4 year mark, and replacement
part prices begin climbing then too. And by year 5 computer manufacturer's are less willing
to extend a warranty or no longer make the replacement parts for older systems. Another
factor is software added to an older server will have higher requirements that the old server
might not meet.
The only reliable way to know when it makes fiscal sense to replace a server is to maintain
detailed performance records and analyze them for signs of aging. Collecting data on
a quarterly basis that look at reliability, uptime, bandwidth consumption, and CPU utilization. A
machine that consistently tops 70 percent utilization or experiences above-average periods
of unplanned downtime is probably costing you more than an upgrade would.
Consider Business Needs When Planning Your Upgrades
By combining those numbers with growth estimates, companies can not only make smart short-term
upgrade decisions but also build a long-term server replacement schedule. A solid plan should
factor in not just projected processing and storage needs but future operating system, database,
and application deployments as well.
Consider Reusing and Recycling Servers
Also worth considering is the possible reuse of old servers for new and less demanding purposes.
For example, obsolete production servers often make perfectly acceptable backup devices,
because their lower performance standards are good enough for brief emergency periods. Click
