Low Power Server

 

Purpose

This page will be used to collect ideas for low power servers. I have been disappointed at the fact that my home power consumption has not improved even though I have replaced incandescent bulbs with fluorescent and plugged appliances into power strips with switches to reduce phantom loads. One additional cost is my web server that is up 24/7 requiring 150 Watts. My humble problem is a microcosm of the issues faced by the server farms at Google and Yahoo. What are others thinking about this problem, and what is to be done?

 

Goal

A low power web server that can run 24/7 using 10 Watts or less. For each 100 Watts a server requires 876 kWh per year. This not only increases my electric bill, it is bad for the environment. Assuming the power is generated from coal, a 24/7 100 Watt load causes 0.4 tons of C02 to be released into the atmosphere each year. A server with power requirements of 10 Watts would require only 87.6 kWh per year.

  1. The linutop could be the replacement for my web server. It only burns 6 watts and boots off a 1 GB USB key containing xUbuntu Linux. It boasts a 433 MHz processor and 256 MB of RAM, 4x USB 2.0 ports. It requires a VGA monitor and USB keyboard and mouse. That leaves one USB port free for a second USB thumbdrive. 8 or 16 GB would provide ample storage for Apache, MySql and PHP as well as a place to store my /var/www/html files. My current web server has:
    1. 597.4 MHz processor (dmesg | grep MHz}
    2. a 10 GB disk. I'm currently using 3.7 GB. The disk and/or fan is just slightly louder than my tinnitus!
    3. 384 MB RAM. 128 MB proved inadequate when I added mysql and wordpress.
    4. I have ordered a Kill-A-Watt device to measure the actual power used.

  4. Make: Need Help Building a Low Power Server See the comments about the NAS (Network-Attached Storage). This is used as a media server within a home. Some models have USB ports that can take thumbdrives and external drives. This really isn't what I'm looking for, but it's interesting.
  5. FreeNAS FreeNAS is a free NAS (Network-Attached Storage) server, supporting: CIFS (samba), FTP, NFS, RSYNC protocols, local user authentication, Software RAID (0,1,5) with a Full WEB configuration interface. FreeNAS takes less than 32MB once installed on Compact Flash, hard drive or USB key. The minimal FreeBSD distribution, Web interface, PHP scripts and documentation are based on M0n0wall.
  6. Intel Personal Server Smaller than PDA-class devices and without traditional input/output (I/O) capabilities such as a keyboard or display, the Intel Personal Server concept prototype links wirelessly to existing infrastructure to provide ubiquitous access to personal information and applications. With a focus on miniaturization, Personal Server technology could also integrate into a PDA or cellular phone, extending the capabilities of current consumer electronic devices. The Personal Server concept would enable any computer with a small amount of additional software installed, to perform as if it were the user's own computer. The local computing infrastructure will support the Personal Server not only by providing a display and keyboard, but also by enabling access to other local resources such as printers, the Internet, and high-performance desktop processing.
