The production server product only supports one active memory channel
board.  It has a mode where a second board serves as a hot standby,
but again only one board is active at a time.  Same is true for the
memory channel driver product.  You should talk to product management
about future product directions.

I am not able to answer your question about the optimal configuration
for NFS.  I have little experience using NFS in the cluster environment.

I think the customer has a big miss understanding...the overhead
of MC is not very high, and a single MC will handle the load they
are placing on the system.  The second MC is for redundancy in the
event of a problem.

We plan to support in a future release, load balancing across
multiple MC.  While this will provide potential greater bandwidth, for
the use your customer describes I don't see them being able to tell
the difference.

I think you need to be clear on what you are trying to improve?  What
data do you or the customer have the MC is a bottleneck in what
they are doing?

If it were to be found to be a bottleneck, the future loadbalancing
would help with this...I don't think you will find it to be a
bottleneck.
