We're running 7.0.3P3, but were thinking of going to 7.2.1.1 at some
point.
>From what I've been told and understand, if you setup NDMP with
indexing (DAR), then you cannot restore more than 10,240 files
individually at a time, which is a big hassle. We have filesystems
with over a million files in them, and some with 5 million plus. I
won't comment on the silliness of the applications doing this mind
you, but...
In any case, we've been told that the problem is that while NetApp can
only handle 10,240 files at a time, they can handle multiple restore
requests at a time, but that Networker doesn't handle it right.
And who thinks EMC has an incentive to make Networker work better with
Netapp?
I'd love to be proven wrong here, it would make us re-think moving to
NDMP in a big way, if only for the performance boost.
