MODAPS System Reliability

LANCE-MODIS operates on a 7×24 hour basis. LANCE-MODIS has two standalone systems that use different network routes. It is expected that this redundancy will reduce the system downtime to less than 1%.

MODAPS Hardware Configuration

Hardware Diagram

The simple architecture used for LANCE-MODIS is shown in the diagram above. The system includes 3TB of production disk and 5TB of archive disk on the FTP server. The latter allows the archive of approximately 5 data days of NRT data products. The system includes 6 minions used for the data production. The initial system uses the Open EBnet LAN. The second system will use the Science and Engineering Network (SEN).
