That won't help. That turns it on (if it's not enabled by default these
days). I need to turn off the behavior I'm seeing, whether it's due to
the filestreams allocator or default inode64. Then again it may not be
possible to turn it off...
Anyone have other ideas on how to accomplish my goal? Parallel writes
to a single AG on the outer platter edge vs the same to all AGs across
the entire platter? I'm simply trying to demonstrate the differences in
aggregate bandwidth due to the extra seek latency of all AGs case.
Thanks,
Stan
