As end-user expectations increase, budgets tighten, security concerns rise and merger and acquisitions occur, data center migrations are increasingly common. If you’re planning to move your data center to a new facility, managed or cloud environment, you need a full understanding of the historical capacity and utilization patterns for your servers and storage assets.
Galileo Performance Explorer, a cloud-based infrastructure performance management solution, is indispensable for planning and managing a flawless data center migration. That’s because, unlike many other solutions, it can monitor and measure data center performance in all environments: on-premise, cloud and hybrid.
With Galileo, you no longer need to struggle with data center migrations. You can put an amazingly simple methodology to work that gives you all the vital answers you need:
1. Monitor Your Infrastructure
Before your data center migration analysis, monitor your IT infrastructure with Galileo for a minimum of 30 days. If your business is cyclical or is undergoing significant growth, you may need to capture data over a longer period for a full understanding of trends and demand spikes.
2. Group Your Assets
Whether your technology assets are in one or multiple on-premise locations or in the cloud, Galileo Tag Manager allows you to tag servers and storage assets that you plan to move and group them virtually for analysis.Whether your technology assets are in one or multiple on-premise locations or in the cloud, Galileo Tag Manager allows you to tag servers and storage assets that you plan to move and group them virtually for analysis.
3. Establish Your Baseline
Galileo provides a snapshot of your virtual grouping’s vital stats — IOPS, latency, throughput, and other essential metrics. Colorful, at-a glance charts use predictive analytics and intelligent thresholds to let you know if usage is trending to a point where you need to take action to keep operations running smoothly.
4. Specify Bandwidth Requirements
Data center migrations often falter because IT leaders fail to size the network pipe correctly. Since Galileo will show the network activity for your virtual grouping, you can specify your bandwidth requirements accurately.
5. Right-Size Your Technology
In Galileo, review the trends in utilization for your servers and storage. You’ll likely find some assets are working overtime while others are practically asleep, enabling you to balance workloads and add resources as necessary. Thus, you can maximize application performance while minimizing costs.
6. Monitor as You Move
Even with all the upfront planning, it’s best to be cautious as you move your applications. Migrate them one at a time. Let the least critical ones lead the way, so you can learn as you go.
Once moved, monitor the applications to see if they are performing the same, better or worse than before. If there is no improvement, dig deeper into Galileo to find the root cause of the issue and correct it. Then put your newfound knowledge to work to ensure the next application you move does not fall into the same performance pothole.
7. Facts to Assess Post-Migration Results
Anytime there is a change, some people will perceive performance lapses. With Galileo, you have the facts to check on their claims. You’ll either be able to refute them or correct the issue rapidly. Either way, it’s a win.
Also, you can use Galileo’s Enterprise Dashboard to show upper management how the data center migration improved performance while reducing costs. Sometimes a little self-promotion is in order.
