Cheat Sheets for Data Center Infrastructure ManagementBusiness-wise, Future-drivenTMIntroduction Data Centers Once upon a time, a data center operator managed a 15 rack data center at a small manufacturing firm. Because his facility was so small, he didnt use any physical infrastructure management tools. Instead, he felt confident in and relied on the tribal knowledge he had acquired over the years. However, over time, his 15 racks became much denser. His energy bills went up and his cooling and power systems drifted out of balance. At one point, when he added a new server, he overloaded a branch circuit and took down an entire rack. While this story begins with once upon a time, it is a true story, and illustrates just one set of challenges in managing a data center without the right tools. Data center infrastructure management (DCIM) tools enable organizations to plan, predict, analyze, and ultimately drive down costs. Without DCIM tools, the business value of the data center can improve only as far and as fast as the human brain will allow. The following cheat sheets and illustrations provide a snapshot look at how DCIM software can improve planning, operations and analytics.

A recently virtualized data center was allowing the VM manager to automatically move VMs based on compute requirements. They failed to consider the possibility of overloading the PDU and ended up crashing.Schneider Electric4 5.
