[McIDAS #HZP-657281]: Moving McIDAS-XCD server

Hi Hsie,

Here is a listing that contains volumes of various feeds available in the
IDD:

Data Volume Summary for idd.unidata.ucar.edu

Maximum hourly volume   5880.553 M bytes/hour
Average hourly volume   4203.884 M bytes/hour

Average products per hour     194633 prods/hour

GEM                       2.023    [  0.048%]       22.248      139.636
FSL2                      1.951    [  0.046%]        2.086       22.182

As you can see, the NOAAPORT NGRID feed, which is composed of higher resolution
model data mostly in GRIB2 format, has twice the volume of the HDS feed on
average.  Another way of looking at the NGRID volume is that it is roughly
75% of the volume of the combination of the NNEXRAD, NIMAGE, FNEXRAD, UNIWISC,
IDS|DDPLUS, DIFAX, GEM, FSL2, and NLDN datasetreams.  So, the addition of
NGRID to the mix would be significant if you are already having bandwidth
problems on al.noaa.gov machines.

Ingesting and processing of the NGRID feed products is, of course, entirely
up to you.  I only asked about getting the feed on stratus if you were
already ingesting it on another of the machines in your control.
