Servers and electrical efficiency

I ran across this a while ago and thought it worth a share.  In summary running a higher wattage power supply might be costing you a bit of extra money!  Aside from the higher purchase price, it turns out that power supplies have a range where they are more efficient.  I haven't done a back to back measuring.  I am sure using HP ILO's and my Kill-A-Watt the differences are within statistical noise.

Also there is gains to be had in running a single vs. dual power supply; however the savings might not be worth the single point of failure.  In my quick testing I did not see any difference on my Kill-A-Watt.




random network cabeling.....

These are garbage!  Who thought it would be a good idea to have a proprietary patch panel?  So instead of using normal network cables that can be purchased almost anywhere one has to source these goofy cables.  The patch panel from the rear is normal punch downs...but the front have these really wide connectors that are almost 3x as wide as a RJ45 connector.  I have learned that they are called Krone HighBand.



It's a bad day when one's marching orders are to install some 10gb Ethernet stuff and the twin-x cable shipped looks like this!  DOH!  It is a good thing Amazon and Amazon lockers!
