I was just reading this piece about 10 ways to tell that your data center is overdue for renovation. Great idea but, unfortunately, that piece was WAY off track, so I’m going to list my 6 ways here.
You don’t need a fancy expensive air flow study to get an idea that your data center has cooling issues. A simple walk through will make significant hot or cold spots very obvious. Significant hot or cold spots means it’s time to rework things.
If you wait until you can’t cram one more piece of gear in, as the article suggests, you’re going to be in a heap of trouble. Make sure all idle equipment is removed and set a reasonable action limit (such as 75% full) to address the space issue BEFORE you run up against the limit.
Contrary to the article, reading equipment load information is NOT a sign that your data center needs to be renovated, it’s just good practice. Nuisance trips of breakers and the need to reroute power circuits from other areas of the data center are a dead giveaway that the original power plan for the data center needs a serious overhaul.
You can’t create an IT strategy without considering technologies as the article would have you believe. First, inventory and evaluate the existing data center, identify where it’s falling short of meeting business requirements and goals, and then consider the technology to get it back on track. Every step in it’s proper order.
When it becomes apparent that the existing data center infrastructure is going to fail on any of the first four points with anticipated changes coming up, it’s time to retire it. Don’t let the problems occur and THEN fix them.
6. Organization and documentation
If touching any part of the data center is a major crisis because of over complication of the systems and/or inaccurate, incomplete, or just plain missing documentation, it’s a clear signal to get it revamped and under control before it causes a complete disaster.
