As the server industry begins a slow recovery the two main points that will affect sales will be:
? !
? !
Ef?ciency and utility cost reductions for end users.
Lower power consumption, bene?ting PUE for data centers.
Another interesting data point is in cloud computing. As this technology takes hold the servers employed in
this sector are increasingly making use of one AC/DC power supply. Forgoing the redundant supply
maximizes ef?ciency, and with redundancy built in at the server level, the redundant PSU is truly
redundant.
At ?rst look, cloud computing could be seen to affect power supply sales, especially if servers are deployed
requiring half the quantity of front ends due to the redundancy criteria. In reality, that may not be the case.
In order to support cloud computing, new data centers are being built, these are typically more ef?cient to
run from an infrastructure point of view, and the servers employed are most likely to be the lowest power
consuming servers available. Cloud computing has to be seen as “green”, and with more devices using
mobile internet, cell phones, net-books, iPads, etc., this is a growing industry.
