Hi Tom,

re:

Excellent!

OK, I like incremental testing :-)

re:
> The nfs disks are fast, easily 1GB/s,

One test that will be very interesting is running with the LDM queue on
a local file system and, after finding out that that runs fine, trying
to run with the LDM queue on an NFS-mounted file system.  I will be
(pleasantly) surprised if the latter test works well.

Excellent.  I don't think that your bare metal LDM installation will
exhibit any problems especially given the very low volume of data that
you want to ingest/process.

re:

Since there is both forward and reverse DNS for cola6.gmu.edu (I checked),
the answer is no.  Given that PSU setup their IDD relay instance the same
way as we setup ours, the answer should be no for them as well.

Cheers,

Tom
