Ethernet Power Study of Cisco and Competitive Products
Every Ethernet switch requires electricity to function. Efficiency is the measure of power relative to amount of work performed. When products use more power to perform the same amount of work, they are by definition less efficient. Low efficiency creates increased costs for a customer. Other factors that should be...

PARAID: A Gear-Shifting Power-Aware RAID
Reducing power consumption for server computers is important, since increased energy usage causes increased heat dissipation, greater cooling requirements, reduced computational density, and higher operating costs. For a typical data center, storage accounts for 27% of energy consumption. Conventional server-class RAIDs cannot easily reduce power because loads are balanced to...
