Building a Linux SAN

[AJ]

Hi all,

Im currently in the process of setting up a linux storage solution for a 
number of ubuntu
servers I'm working on at the moment.  I'm planning on using a hardware 
RAID device connected to them
via a fibre channel fabric.   What I'm wondering is if anyone else has 
implemented anything like this before, and what clustering filesystem 
you chose.  At the moment, i'm tossing up between Coda and GFS for the 
filesystem and any feedback on the performance of these systems would be 
a great help.

Cheers,

- AJ
