The data center retail colocation market is highly competitive and growing. Providers are under continuous pressure to be resource efficient while being ready to scale and meet tenants’ evolving demands. In addition to this increasingly complex and challenging environment, tenants are demanding transparency on billing, SLA performance, and environmental sustainability metrics. Modern data center infrastructure management (DCIM) software can be an effective tool to help address these needs. This paper will show with practical examples how modern commercial DCIM software makes colocation data center operations more competitive by improving resiliency, security, environmental sustainability, transparency, and operational efficiency.
