Provisioning and managing white space within a data centre (the primary place where the rubber meets the Internet highway)

Data centres are often build and parameters are decided by external engineering and environmental factors and at the last possible moment the white space is shoe horned into the design. This is true of many co-location sites where the designs vary and change continuously during the life time of operations of tenant occupancy. These fundamental design choices are often problematic when populating a data centre or during migration. I have previous written about "5 practices that need to be taken into account when migrating to a more modern data centre" but this article will expand on provisioning and managing white space within a data centre. The white space is afterall the primary place where the rubber meets the Internet highway.
