And on, say 32 parallel writes?

Thanks for that info. I validated with a simple experiment on a Niagara
machine, by viewing 'mpstat' that no more than 2-3 threads were being saturated
by my large block sequential write test.

The experiment was on a V240. Throughput wasn't the issue in our test; CPU
utilization seemed to drop by approx. 50% after turning checksum off. The
concern was in potentially running out of CPU horsepower to support multiple
parallel sequential writes.
