Success is in the Details
Last week I discussed why discovery is important and some questions to ask before starting the process.
Today’s post is about the details that are most likely to trip up a major data center project. One piece of seemingly trivial hardware that isn’t moved over to the new environment can shut down a vital system or, because of interdependencies, multiple systems.
The first two items involved in discovery that we’ll discuss are servers and storage.
The workhorses of your data center, information collected for every physical server should include: manufacturer and model number; physical attributes (memory, CPU, storage, NICs, HBAs); firmware; location; MAC addresses; IP addresses and VLANs; configuration settings; operating systems or hypervisors; virtual servers […]
“Doesn’t the IT department already know what hardware and software they have, how it interacts and which users those assets support? After all, IT supports its systems every day.”
It’s a valid question, and the answer, unfortunately, is probably “no.” Or, not in the detail required to successfully complete a data center move, consolidation or cloud migration without running into serious problems.
The discovery phase is the critical first stage of a data center transformation project. In a complex environment, this phase can last months, particularly if performed manually. But businesses are not static. While the discovery phase is ongoing, new equipment may be added or decommissioned, new virtual instances created, and applications changed. Consequently, unless care is undertaken, the discovery phase deliverable may be out of date before it is completed.

Change is the biggest headache for most IT organizations. Especially when they are contemplating making a significant investment in transforming their environment. Tell you something that you don’t know, right? The sun rises in the east…..
But, have you thought about why it is so difficult?
- Good old human nature: fear, doubt, uncertainty. Given.
- You are busier than a one armed paperhanger back when they hung wallpaper sometime in the last century.
- You are constantly fighting fires and responding to user issues. How someone can remotely jam a multipurpose printer 3 times in a row is beyond me.
- You are continually monitoring for security breaches. Now, add in regulatory compliance requirements built for a Fortune 100 company with the equivalent resources. You get security is incredibly important, but it creates a significant […]
When it comes to Change Management processes, just pretty good can get you in big trouble. Sure you have an established process but can you say it’s always followed? Even when change requests follow the proper approval process you still have to deal with deviations that often go undocumented.
Say it’s a web server or database upgrade. It’s not uncommon for Systems Engineers to make a few “tweaks” on the fly and either forget or choose not to document them. Why? Maybe they’re too busy to report “small” changes or perhaps any changes need to go to CAB but there’s no time for all that “bureaucracy”.
Why is this a problem? The “tweak” itself could be harmful or break something else that doesn’t get detected for a while. When it does manifest as a problem (seemingly always going into a weekend) changes […]
