Hi list,
I would like to hear some opinions about a configuration: I have a dual 
Xeon with 2 RAID5 HW controllers, so that from the OS side I have two 
SCSI disks. I am trying different configurations to see which one has 
the best performances. The machine will be a file server for a bunch of 
The question is: would you use LVM over a SW-RAID0 between the two SCSI 
disks? Is native LVM striping that better (in terms of performance I mean)?
Let me know, I'll run bonnie++ meanwhile, but I don't know if it 
highlights the differences: I should simulate a multiuser stress of the 
disks. Any advice?

ciao rob
