Summary
Data Centers & SANs: Rapidly Growing SCS Applications

Vast amounts of new information being created,
communicated & stored

Legislation & other business priorities impacting data center &
storage area network growth

The TIA-942 Data Center Standard applies structured cabling
principles as TIA/EIA-568 did for commercial buildings
