Hi Wen, re: > Requesting same data product from multiple upstream servers, do I need > upgrade our LDM? We are currently using LDM 6.7.0. No, there should be no need to upgrade your LDM installation, but it couldn't hurt :-) One thing to make sure of, however: The redundant data REQUESTs must be identical (i.e., same datastream(s) and same regular expression describing the products wanted). For instance: request NEXRAD3 ".*" idd.unidata.ucar.edu request NEXRAD3 ".*" idd.cise-nsf.gov If the datastream(s) or regular expressions are not the same, there can be unexpected (but completely explainable) consequences.
