Market Data Center Efficiency

Having spent the last few years calculating, monitoring and measuring data center efficiency, my coworkers and I created our own unit of data center efficiency; the kengell.

kengell -- A data-center efficiency metric.

• Main Entry
  • kengell
• Pronunciation:
  • 'king-gull'
• Function:
  • technology term
• Keith Engell 1962- ; American computer scientist
  • a data-center measurement equal to one message processed per one unit of power
    • NOTE: one Joule = one watt-second or rather 1W = 1J/s

Example:

An application on a server processes 500,000 messages in one second. The server consumes 160 watts (160 Joules/sec). The application has a data-center rating of 3,125 kengells or 3.125 kilokengell (kK)

500,000 messags/sec / 160 J/sec = 3125 messages/Joule = 3125 kengells (or 3.125 kilokengell)
