My NSLU2 has been working as a weather/web server for a little over a month now. I have noticed several delays in the NSLU2’s ability to serve up web pages. As a weather server it would work fine. But to add the functionality of serving web pages has taxed the unit to the max. Three times during the past month, the weather software (wview) has locked up requiring either a restart of the weather daemons or a reboot of the processor.
So, I decided to get something with more power, but yet keep the power consumption low. A fan-less computer would be ideal. I looked around and found the Habey BIS-6561. This computer is fan-less, uses a 2-core Intel Atom N330 processor running at 1.6 GHz. It comes without RAM or a hard drive. I found that NewEgg had the processor and the max of 2 GB of RAM at a $20 savings. I also decided to go with a 2.5 inch sold state drive (SSD), and for this I chose the G.SKILL Phoenix PRO 120GB SSD with Read: up to 285MB/s and Write: up to 275MB/s.
Since the BIS-6561 has two external USB ports. I downloaded the 64bit version of Debian Lenny 5.0.5 to my desktop system and used a linux application [unetbootin] to create a bootable USB stick on one of my 4 GB USB memory sticks I had available. To install Debian, I plugged in a monitor and keyboard to the BIS-6561 processor, and also plugged in the memory stick before powering up the processor. The installation was really fast using the SSD. I don’t remember how long it took, but it was very fast. I know the install of Debian took less than 30 min.
The system has been up and running for two days now, with no delay serving up the web pages.
My only problem with the processor is the temperature of the box. It is currently running with an outside case temperature of 107 degrees F. In the next couple of days, I will get a small fan to place on the desktop aimed at the processor. I had three empty Altoid tins that placed under the processor to allow for some air flow underneath.
Right now, I have the server plugged into a Kill-A-Watt meter to check the power consumption. The current draw is 0.35 amps (as seen in the right photo below) and the voltage is 117 volts. You multiply the two together and get 40.95 watts. Although the Kill-A-Watt meter says the power is 22 watts ???
