In december last year I started the so far biggest upgrading process. The overall target was 3 machines which really needed new / newer hardware…
I started with my old Intel Pentium D930 – which was great at its time – but today it’s just to slow. It was replaced with an Intel I5-750, 4DB DDR3 RAM and a new graphics accelerator.
Of course there were some problems – which is quiet usual with new hardware. In my case it was a harddisk with bad sectors – which I realized on 23rd in the evening – meaning I had to find a store on 24th of december to get a new harddisk. After succeeding in this task everything went pretty smoothly. And the new hardware made quiet a speed difference ;)
Second step was quiet recently. I purchased an Intel I7-930 with 6GB DDR3 RAM which replaced the I5 in my main machine. The I5 then was moved to my secondary machine and replaced an AMD Athlon X2 3800+. Again quiet a boost on both machines – and on a side note: if you are compiling all your programs like on FreeBSD or on Gentoo Linux I really can recommend the I7 (quad core with HT).
Again during this upgrade I had some troubles – but nothing that serious – so both machines were up and running within 2-3 days.
The third step is yet undone but it will be the replacement of my server/router’s hardware (Athlon XP 2000+, 768MB RAM) with the Athlon X2 3800+, 4GB DDR2 RAM. Despite the fact that I already have all the hardware for that I have not yet done it because I want to have close to zero downtime – and I’m unsure yet how to accomplish that (that and the whole data migration still causes me a little headache)
