We are about to install a new PostgreSQL server, and despite of being a 
very humble configuration compared to the ones we see in the list, it's 
the biggest one we've got till now.

The server is a Dual Xeon 3.0 with 2 GB RAM and two SCSI disks. Our main 
doubt is what is the best configuration for the disks. We are thinking 
about use them in a RAID-0 array. Is this the best option? What do you 
suggest on partitioning? Separate partitions for the OS, data and pg_xlog?

We'll have some time to work on performance tests, and if someone is 
interested we can provide our results.

Thanks in advance,
