NAN Data Transport System
NDTS Facility Manager Guide
The Network for Advanced NMR Data Transport System (NDTS) enables automated harvesting of NMR acquisition data from spectrometer workstations and delivers it securely to the NAN Repository. Facility Managers are responsible for installing and managing the local components of the system, ensuring connectivity, and supporting user access to collected data.
System Architecture and Data Flow
The NDTS system consists of local and central components working together to collect, transfer, store, and index NMR experiment data.
| Component | Location | Role |
|---|---|---|
| Daemon | Spectrometer Workstation | Detects completed experiments, associates metadata, and sends data to the Gateway. |
| Gateway | Facility Server | Receives data from all Daemons and relays it to the Receiver. |
| Receiver | UCHC Data Center | Accepts experiment data and metadata from Gateways. |
| Parser | UCHC Data Center | Extracts parameters, user info, and structural metadata from each dataset. |
| PostgreSQL Database | UCHC Data Center | Stores structured metadata and associations (users, instruments, facilities, samples, etc.). |
| Primary Storage | UCHC Data Center | Stores canonical copies of all collected experimental data. |
| Disaster Recovery Storage | Off-site | Maintains redundant backups of all experiment data. |
| Elasticsearch Database | UCHC Data Center | Indexes experiment metadata for search and access via the web portal and APIs. |
Data Flow Summary:
- A user completes an acquisition on a spectrometer.
- The Daemon detects the completed experiment and sends it to the Gateway.
- The Gateway transmits the data to the Receiver at UCHC.
- The Receiver accepts the data and hands it off to the Parser.
- The Parser extracts metadata and stores it in the PostgreSQL and Elasticsearch databases.
- The experiment data is stored in primary storage and backed up to disaster recovery storage.
- The data becomes visible in the NAN Portal (e.g., Data Browser, vNOC) within seconds.
Failures at any stage result in data being spooled locally and retried automatically.
Facility Manager Responsibilities
Facility Managers are expected to:
- Install and configure Gateway and Daemon software
- Monitor daemon heartbeat and transmission status
- Support users in selecting correct metadata (e.g., NMRhub usernames, projects, samples)
- Reassign “unselected” or misattributed data
- Use the Facility Dashboard to review health status and harvested experiments
