Dell announced a new line of their Poweredge servers, the Power Smart models 1950, and 2950 that are supposed to be 25% more power efficient than their standard counterparts. This follows their launch of the Optiplex power saving desktop computers back in September.
The servers will only take up 40 watts of power compared to the 65 or 80 watts of standard servers. They had to make some changes to achive this power saving. The server uses 2.5″ floppy drive, special fans, and software to reduce system power during periods of low activity.
These savings may not seem like much, but can save a significant amount of money in power costs for larger companies.
