I was looking for this info, online, but with no luck so far. What I'm really interested to know is this: * Say, you have a mixed sequential workload 75% reads, 25% writes with queue depth greater than one, then: ** are all writes executed before all reads? ** are there any reads from the blocks not yet written to? ** are there any reads performed against writes that are not ack'ed yet? ** are there any writes performed to the same blocks that have a pending read request? * Does any of the answers change if we modify the ratio of reads to writes, sequential to random? Thanks! Oleg
