Planned webservers replacement, upgrade to Debian Squeeze and switch to x86_64 architecture

Posté le mercredi 1 juin 2011, à 17:14 UTC

We received yesterday the hardware bought with the money received from our recent donation campaign. Say hello to our new web cluster based on Core i7 CPU and 24 GiB of DDR3 memory per node.

At the same time we are going to switch from Debian Lenny to Debian Squeeze, please check that your websites work with all the software provided by Debian Squeeze (PHP 5.2.6 to 5.3.6, Perl 5.10, Python 2.4&2.5 to 2.6, and so on).

Also, we were stuck in x86_32 architecture due to hardware limits for a while and this is not the case anymore. So we are going to switch from x86_32 to x86_64, please check that your compiled stuff (if any) work in x86_64 and then prepare you to recompile your stuff after the switch. There will be probably no IA32 emulation available because we don't want to bloat our systems with compat librairies, so please be prepared to deal with it.

And yup, as we are quite excited about putting up the new hardware online, you only have a few days to do those checks :p

As usual, contact us if you need more information.
