| 3 | 4 | Andrew Norman | The DAQ Cluster for the Near Detector on the Surface (NDOS) is currently housed |
| 4 | 4 | Andrew Norman | in the Lattice Computing Center (LCC) at FNAL. The cluster consists of 28 computing |
| 5 | 4 | Andrew Norman | that are designed to serve either as farm "buffer nodes" or as individual servers/hosts |
| 6 | 4 | Andrew Norman | for specific DAQ processes. |
| 7 | 4 | Andrew Norman | |
| 8 | 4 | Andrew Norman | In the current configuration the cluster has the following configuration: |
| 9 | 4 | Andrew Norman | |
| 10 | 4 | Andrew Norman | Servers/Hosts |
| 11 | 4 | Andrew Norman | |
| 12 | 4 | Andrew Norman | * Master Server (hosts all critical servers) |
| 13 | 7 | Denis Perevalov | * Runcontrol (runs the Run Control application) |
| 14 | 7 | Denis Perevalov | * Trigger (runs Global Trigger application, as well as SpillServer Receiver) |
| 15 | 4 | Andrew Norman | * Data monitor (datamon) |
| 16 | 7 | Denis Perevalov | * Message Logger (Runs the message facility server and stores all DAQ log files locally in /daqlogs) |
| 17 | 7 | Denis Perevalov | * Backup Server (backs up major directories, such as /home/novadaq, ganglia database) |
| 18 | 4 | Andrew Norman | * Database |
| 19 | 4 | Andrew Norman | |
