Introduction to DCIM


What is DCIM?

DCIM (for Data Center Infrastructure Management) is the global management of all physical equipments present into a Data Center. DCIM manages the entire lifecycle of these resources. DCIM addresses all IT equipment and non-IT ones*. It responds to both implementation and operational concerns.


* As cooling engines, air-flows fans, power-AC, access control and physical security components, wire pathways, racks, etc.

Its objectives are multiple. Some are obvious as to prevent proactively from hardware failure, optimize hosting capacities, optimize energy consumption, reduce cost or carbon footprint. Some others are less as to manage risks relating to equipment density and overheat, or adjust the dynamic resource allocation according to workload. 

What does support DCIM expansion?

This quite recent approach (named since 2010) is largely supported by an increasing demand for digital services and the necessity to provide more IT capacities. Worlwide Data Center capacities are doubled every 2 years. The cause is: computerization of most business lines, customer services boom, e-shopping, big data, and cloud services.

 

Although, this tendency is bore by IT cost reduction necessity, companies have to deliver their products and services in a more profitable way. Most have undertaken the consolidation of their Data Center to bigger and more efficient ones. Unable to build new ones, some of them have to retrofit existing structures increasing the utilization density of each square foot. “Blade” technology and virtualization had helped to mass virtual servers onto a limited number of physical machines. 

     

What are de DCIM contributions?

DCIM is mostly materialized through management software. It includes know-how, methodology and may be evolving to a specific best-practice framework. What is called DCIM today is primarily represented by an ever-changing software suite, covering a large number of sophisticated functions.
