## MODAPS

- MODAPS produces 2.4TB/day and ships 1.2TB to DAACs for archive and 1.1TB to Science Team when running at 3X
- 1x forward processing for Terra and 2x reprocessing
- Current processing systems are:
- 80p SGI Origin 2000 for forward processing and
- 64p SGI Origin 3000 for reprocessing

## MODAPS 2002

- 140 dual-processor systems running Linux will be added to the SGI Origins in March 2002
- Linux processors will run Level 2 through Level 3 Daily products (70% of processing load)
- PGEs have been ported and products are being verified by Science Team (due date 1/31/02)
- In testing, 32 Linux systems =1X production
- Disk increased by 60TB to handle extra volume
- Can meet required 4X (3x Terra, 1X Aqua) for 2002, Aqua volume is still at 2/96 baseline

- 12/19/01

## Upgrade Test System

- Adding 32 Linux processors to existing 16 processor SGI Origin 2000
- Adding 9TB of disk to test system (11TB total)
- Allows science testing at 1x
- Test system will be used to test both PGE and MODAPS system changes
- Global test data sets are being defined to allow better science testing of  8, 16, 32-day products

## Future

- Finish Linux product verification          1/31
- Install redundant power for production  2/02
- Improve Export error handling               3/31
- Machine-to-Machine Ordering for Reprocessing                                           7/02
