MANAGEMENTANDOPTIMIZATION
Lackofvisibility intoassets isa
recurring themewhendiscussing the
causesofoperational inefficiency. This
canbecorrectedbycreatingand

Onceestablished, itbecomesa

Thedatacenterappliancementioned

•Prioritized:
Theproblemdatacentermanagers

thatcriticaloperatingdata isnot

TECHNOLOGY: INFRASTRUCTURE
THATCREATESTHEFOUNDATION
FORGROWTHANDAGILITY
Thedatacenter infrastructure—power
andcoolingsystems thatensuresafe
andcontinuousoperation—often
represents the leastagileandscalable
componentof thedatacenter. If
improperlydesignedandmaintained, it
canconstraingrowthandcontribute to
downtime.Conversely, the right
infrastructurecreatesa foundation for
continuousavailability, increased return
oncapital andcost-effectivegrowth.
STRATEGIESFORSCALABILITY
Heatdensityhasbeenoneof the top

according toDCUGsurveydata,
