Introduction
The intelligent rack power distribution unit ( rack PDU ) has revolutionized data centers . As the last link of the elaborate data center power chain , the traditional role of the rack PDU is to deliver stable and reliable power to devices in the rack . It provides the electrical heartbeat to the systems running the critical applications that support the operation of a business ( or that , in some cases , is the business ). In years past , rack PDUs were often considered a simple commodity , just power strips to plug devices into . Typically , IT staff merely told facilities how much power was needed at the rack based on device nameplate specifications . The thought was that this information would provide plenty of headroom and ensure minimal risk of down-time . Little thought was given to the added value the rack PDU could provide until recently .
Over the past few years , system availability has become a given , and data center management attention is now focused on managing operational costs , efficiency improvements , sustainability , and resource optimization . With the annual expenditure for powering the average data center surpassing the cost to buy the IT equipment itself , the efficient use ( and waste ) of energy is now targeted as a priority . Beyond the actual cost to power a data center , related issues affect current operations and future expansion – e . g ., physical space limitations , utility power availability , carbon footprint impacts , capacity , and potential government regulation . � www . intelligentdatacentres . com
