Within a data center, how many concentric layers are considered necessary to provide effective security?
Within a data center, if you have a system which includes one extra unit, in addition to the minimum required to satisfy the base need, and where the failure of this unit will NOT disrupt operations, what level of redundancy would this represent?
You are designing a cabling containment system installed overhead in a new data center. The main or prime purpose of the system will be to manage fiber optic cabling between cabinets. You have a choice of designs of the containment system. In view of the prime purpose of containment system, your first choice of design will be one that:
It is important to keep all underfloor cabling systems very neat and orderly. Cabling systems must be managed to ensure that air flow is not impeded by the height or volume of underfloor cabling. Keeping copper communications cabling properly separated from is one design approach. To resolve this:
This type of cable is an unbalanced system:
