Sure, but putting the entire management burden of obtaining and
running defrag tools in every one of their large set of OS's is the
wrong approach.
We can and should be designing new functionality for the data center
in such a manner that does not require large scale manual
intervention to maintain the systems. Your customers won't thank you
for solving the thin provisioning management problem by requiring
them to do extra hand-holding....
I agree that it could be done better.
I just don't expect that to happen any time soon because
both multiple array vendors and multiple OS vendors must
agree and spend money when they don't see this as a large
amount of missed opportunity money. You only have to be
as good as your competition and the customers are used to
doing the extra hand-holding.
All we can do is support what the devices will do today
with minimal effort and wait for customer demand to force
everyone to make improvements.
