As flash storage has permeated mainstream computing, enterprises are coming to better understand
not only its performance benefits but also the secondary economic benefits of flash deployment at
scale. This combination of benefits — lower latencies, higher throughput and bandwidth, higher
storage densities, much lower energy and floor space consumption, higher CPU utilization, the need
for fewer servers and their associated lower software licensing costs, lower administration costs, and
higher device-level reliability — has made the use of AFAs an economically compelling choice
relative to legacy storage architectures initially developed for use with hard disk drives (HDDs). As
growth rates for hybrid flash arrays (HFAs) and HDD-only arrays fall off precipitously, AFAs are
experiencing one of the highest growth rates in external storage today — a compound annual growth
rate (CAGR) of 26.2% through 2020.
This white paper discusses the issues making data center cooling more challenging than ever and explains why starting the data center design process with the racks rather than the room can help businesses reduce energy consumption, increase capacity and optimize floor space utilization.
