Introduction
This page is summarizing the current setup/configuration of the NL cloud of the ATLAS Distributed Computing (ADC).
Apart from that, it also logs the used-to-happen issues during the day-to-day operation works.

Data Management Services
- Storage Resource Manager v2.2: deployed on each site as common interface to storage elements
- gLite File Transfer Service (FTS): deployed at SARA serving the T1-T1 and T1-T2 data transfers to the sites of the NL cloud
- LCG File Catalog Service (LFC): deployed at SARA for cataloging grid files stored on the sites of the NL cloud
Data locations among SARA and NIKHEF

Trouble shooting logs
=== Sept. 2008 - huge transfer backlog from T2s to SARA Problem fixed by running the FTS admin tool to slim down the FTS job history db table.
=== Sept. 2008 - SRM request timeout reading data from SARA A cron job fixing orphan file issue of dCache loads PNFS server so it was stopped. Also observe a broken network switch involving 4 new dCache node. The problematic network switch has been replaced. A broken dCache node is also replaced.
