Hi, My point about the UPS is that an off-grid setup doesn't need one which somewhat offsets the additional cost of supporting a hard drive. Currently the two schools in Lesotho are using MSI Nettop as school servers. In the context of charging 30-100 XOs, the additional power consumed by the

Hi, What is the disk capacity required by internet-in-a-box? The purpose of the server is to deliver the information not available from the internet. The cost of a UPS which is required for a system on the grid is $80-100. In my experience, there is need for one school server at a school su

Oops, forgot to actually cc Richard. Here's some more Google searching of SSD v/s HDD prices. Capacity HDD price SSD Price Price difference 64 GB $25 $50 $25 128 GB $33$100$67256 GB$40$200$160512 GB$55$430$375 If you can manage a server with a 128 GB drive, then SSD seems to be the way to go. At

Thanks Anish, that was my gut feel as well; for a solar powered server, solid state storage ought to be cheaper than spinning rust. The argument changes once the power system has to do a lot more than power the server. The incremental cost is then hidden. -- James Cameron http://quozl.linux.org

Hi, I have been trying to crunch some numbers and the results seem interesting. I don't claim the calculations to be correct, so if someone with more knowledge (than me or a quick google search) can reply, would be very useful. The average difference between power consumption of an SSD and a HDD

We have just received confirmation that compulab won't be releasing a SATA connector with the utilite. ( http://utilite-computer.com/web/home ) Instread they will offer a mSATA connection. So far, they have not been willing to clarify if the change is due to heat, power, or marketing. As shipped
