Recently, I called on a TDS client for whom we had just completed a data center assessment in advance of an upcoming move we are going to be executing for them. As we listened to them, I was struck by the pressure they were getting from senior management and the company’s board to articulate a “strategy” for cloud computing. With all the focus on cloud, it’s an obvious question — but still one they struggle with.
One of the most common questions that we are asked is “How can I shorten my Data Center downtime window?” After more than 10 years of move events and hundreds of lessons learned sessions, we’ve developed procedures and methodologies designed for the shortest downtime window possible. Here is our list of the Top 10 tips.
During data center migrations, one of the more interesting and challenging areas in the entire project is in the development of the move bundles. It is during this phase of the project where the “art” meets the “science”. The challenge is to balance the needs of the business, i.e. “I don’t want any down time for my applications” with time, technology, budget and human resource constraints. Advanced automation and replication technologies in the market place have eased some of these concerns, but the balancing act between these entities must still be maintained.
Christopher Columbus was at sea 71 days before discovering America. If your Data Center Migration project plan includes more than 71 days for discovery, something’s probably wrong.
Obviously, the Data Center Discovery phase is one of the most important stages of a Data Center migration project. If performed efficiently, discovery focuses on a set of key interviews with SME’s (subject matter experts) from within your organization coupled with experienced consultants who know what to ask for and where to look for it.
Anyone who has been through a data center migration will tell you that the key to success is planning, planning and more planning… and they are not wrong. There are several times throughout the process that will require you look at the data that’s been collected and analyzed and to make sure your plan matches the desired results of the upcoming migration event. Walking through the migration execution plan in advance of the actual move is one of the more critical data center migration best practices. We call this a Tabletop exercise, others may call it a dry run.
