A server, which is ready to work by the insertion into the socket is difficult to imagine. At least until you don’t know about the server from SheevaPlug.
The server of SheevaPlug has a very compact design, that is very similar to the network adapter.
Under the hood of this device you will find 1.2GHz processor, 512MB flash memory and 512MB of RAM memory also. It has also the following external connectors:
1. USB (2.0)
2. 1Gbit Ethernet
Hard to imagine, but this server consumes only 5W of power.
The device costs only 99 $ and I suspect that in the future these devices will be more cheaper.
I would buy it, if I had no any server. But I have a server at 1&1
