Linux - postgres RAID

[Rick Gigger <rick@xxxxxxxxxxxxxxxxxxxx>]

I figure this would be a good place to ask. I want to build / buy a  
new linux postgres box.  I was wondering if anyone on this list had  
some experience with this they'd like to share.  I'm thinking  
somewhere in the $7k - 15k range.  The post important things are  
write speed to the disk and good linux driver support for the raid  
card.  Can anyone recommend a specific raid card / server vendor?

Thanks,

Rick
