Overview
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.
NDTS Components
The NDTS system consists of local and central components working together to collect, transfer, store, and index NMR datasets
| Component | Location | Role |
|---|---|---|
| Daemon | Spectrometer Workstation | Detects completed experiments, associates metadata, and sends data to the Gateway.
Sends heartbeat information to the Gateway Pull user information from the Gateway |
| Gateway | Within NMR facility network | Receives data from all Daemons and relays it to the Receiver. Pulls user information from the NAN Receiver |
| Receiver | UCHC Data Center | Accepts experiment data and metadata from Gateways
Packages user information destined for the spectrometer workstations |
| Parser | UCHC Data Center | Parses datasets to extract additional metadata, writes database entries, and stores dataset files to primary and disaster recovery storage appliances |
| PostgreSQL Database | UCHC Data Center | Stores datasets and their structured metadata |
| Primary Storage | UCHC Data Center | Stores canonical copies of all collected experimental data |
| Disaster Recovery Storage | Geo-dispersed | Maintains redundant backups of all experimental data on a WORM S3 bucket |
| Elasticsearch Database | UCHC Data Center | Indexes statistics about harvested datasets and heartbeat information for visualization from the virtual NAN Operation Center (vNOC) |
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
- Manage facility users through the Facility Dashboard
- Reassign “unselected” or misattributed data through the Dataset Browser
- Monitor the health of NDTS for their facility, including heartbeats, through the virtual NAN Operating Center (vNOC)
