[OSM-dev] Hardware Requirements

[Graham Jones]

Hi All,

I have a little application that uses XAPI to download  city sized lumps of
OSM data, which it puts into a posgresql database for rendering.   It is
becoming increasingly unreliable because of the problems with XAPI servers,
so I am wondering what it would take to host my own database of the whole
planet and keep it up to date to improve reliability.

My current home server (an old laptop, 2 core intel based with about 2GB ram
running Ubuntu 10.10) works nicely doing daily updates for the UK only, but
took several days when I tried to upload Europe, so I haven't tried to do
the whole world on it.
I wondered what sort of hardware people think is required to import and
maintain a database of the whole planet?

The other thing is that it is using posgresql 8.4, but I think 8.3 is
supposed to be faster - is the difference significant enough for it to be
worth me changing to 8.3?

I also worry about my carbon footprint, so minimum power consumption is
important too (that's why I like my old laptop as a server -  <30W for what
is a fairly powerful computer.

Any thoughts would be appreciated!

Regards


Graham.
