if NRT1 is down they will manually point users to NRT2. This should be transparent to user.
NRT1 and 2 are in the same building but on different power supplies. in the event of a disaster there is another machine in another building but this is in ops

web areas for pickup are on Primary and Secondary; user can link to either; 
subscription would work similar to ASDC; believes you cannot send duplicate metadata to ECHO or EMS; in test mode for metrics need Lalit review; sounds like GIBS needs firewall rules to handle dual streams and switchovers so they are happy with one

  1. EMS metrics use metrics from both strings. Lalit confirmed they take the minimum latency of the two, NRT 1 and NRT 2.

    CMR currently takes granule metadata from the primary server NRT1.

    Dana Shum and Doug Newman commented on whether the ECHO and CMR could handle the additional 'duplicate' granules. Doug confirmed they could ingest the additional volume of granules but they questioned if this duplicate is 'the same' data then it might cause confusion to the user.
