MLS L0 data

• Datatypes: – ML0ENG1, ML0ENG2, ML0ENG3, ML0ENG4, ML0ENG5, ML0ENG6 – ML0MEM, ML0SCI1, ML0SCI2– ML0ENG1X, ML0ENG2X, ML0ENG3X, ML0ENG4X, ML0ENG5X, ML0ENG6X– ML0MEMX, ML0SCI1X, ML0SCI2X– ~400 GB/year

• Data Source: EDOS• Level-0 migration is complete and S4PA reconciliation with ECS holdings has been done • Cutover of L0 flow from EDOS completed January 2007.

• Archive– Primary Archive Location : auraraw1– Replicated Archive Location: rep1

• Backups – Incremental backups performed daily– Backup tapes (full backup, primary archive) taken to B28 weekly

• Distribution– L0 data unpublished, unadvertised in hidden directory– FTP; Subscriptions to MLS SIPS (PDS) and MLS SCF (EDS) are activated on auraraw1; MRI is

configured for subscribers on auraraw1
