| Hi Lee, Lustre users
-
A few weeks ago you
sent me these graphs and we have set our mind on finally resolving the mysteries
surrounding sriping.
We have many
confusing situations.
Recently I claimed
that a prime striping count ;could aid in avoiding accidental overload of
OST's. You sent me two graphs, that are interesting.
1. It
seems that for writing the prime number (7) is definitely helping - the
bandwidth is much higher.
=>; There
are some unexplained dips - which I'd like to understand.
2. Reading is
worse, much worse with 7 than with 8.
=> Why is reading
worse?
We are
not seeing this everywhere, and I am sending this message to provoke
sufficient response from the community to hopefully lead to some
understanding.
If other people have
similar graphs, we would love to see these here and get the open think tank
going.
Thanks.
- Peter
