Thanks guys.

Tamil,

How does SCSI RAID controller controls reads and writes on a RAID 0 disk array?

Assuming the stripe size of 64K and an insert is trying to write to a datafile that is striped on all three disks and a query is trying to read from tables and indexes that are striped on all three disks, how does the RAID controller handles the requests? Does it permit asynchronous read and write on all the disks in parallel? Where can I get info on this?
