by ADMIN 45 views

=====================================================

Transferring data from NCSU's NFS storage to SciNet requires a well-planned strategy to ensure that only essential data products are moved, while redundant or unnecessary files are left behind. In this article, we will provide a high-level overview of the data stored in NCSU's NFS "lockers," document the structure and organization of the storage directories, identify important data products that must be transferred, and highlight data that is not necessary or redundant and does not need to be moved.

Understanding the Current Data Structure

NCSU's NFS storage is organized into several directories, each containing a specific type of data. The current NFS storage locations include:

  • s/screberg/longterm_images (semif)
  • s/screberg/GROW_DATA (semif)
  • s/screberg/longterm_images2 (semif)
  • r/raatwell/longterm_images3 (field)

These directories contain a vast amount of data, including images, research data, and other files. To develop an effective strategy for transferring data to SciNet, it is essential to understand the structure and organization of these directories.

Documenting the Storage Directories

The storage directories are organized in a hierarchical structure, with each directory containing subdirectories and files. The following is a high-level overview of the storage directories:

  • s/screberg/longterm_images:
    • images/
    • metadata/
    • processing/
  • s/screberg/GROW_DATA:
    • data/
    • metadata/
    • processing/
  • s/screberg/longterm_images2:
    • images/
    • metadata/
    • processing/
  • r/raatwell/longterm_images3:
    • images/
    • metadata/
    • processing/

Each directory contains a specific type of data, and the subdirectories are organized in a logical manner. Understanding the structure and organization of these directories is crucial for developing an effective strategy for transferring data to SciNet.

Identifying Important Data Products

Not all data stored in NCSU's NFS storage is essential for the research project. Some data may be redundant, unnecessary, or outdated. To develop an effective strategy for transferring data to SciNet, it is essential to identify the important data products that must be transferred.

Data Products to Transfer

The following data products must be transferred to SciNet:

  • Images: All images stored in the s/screberg/longterm_images, s/screberg/longterm_images2, and r/raatwell/longterm_images3 directories.
  • Metadata: All metadata stored in the s/screberg/longterm_images, s/screberg/GROW_DATA, and s/screberg/longterm_images2 directories.
  • Processing files: All processing files stored in the s/screberg/longterm_images, s/screberg/GROW_DATA, and s/screberg/longterm_images2 directories.

Data Not Necessary or Redundant

The following data is not necessary or redundant and does not need to be moved:

  • Duplicate files: Any duplicate files stored in the NFS storage directories.
  • Outdated files: Any files that are outdated or no longer relevant to the research project.
  • Temporary files: Any temporary files stored in the NFS storage directories.

Developing a Data Transfer Strategy

Based on the analysis of the current data structure, essential data products, and redundant or unnecessary files, a data transfer strategy can be developed. The following is a high-level overview of the data transfer strategy:

  1. Identify essential data products: Identify the important data products that must be transferred to SciNet.
  2. Document storage directories: Document the structure and organization of the storage directories.
  3. Transfer data: Transfer the essential data products to SciNet.
  4. Verify data integrity: Verify the integrity of the transferred data.
  5. Delete redundant data: Delete any redundant or unnecessary data stored in the NFS storage directories.

Implementing the Data Transfer Strategy

To implement the data transfer strategy, the following steps can be taken:

  1. Create a data transfer plan: Create a data transfer plan that outlines the steps to be taken to transfer the data.
  2. Develop a data transfer script: Develop a data transfer script that can be used to transfer the data.
  3. Test the data transfer script: Test the data transfer script to ensure that it works correctly.
  4. Transfer the data: Transfer the data using the data transfer script.
  5. Verify the data integrity: Verify the integrity of the transferred data.

Conclusion

Transferring data from NCSU's NFS storage to SciNet requires a well-planned strategy to ensure that only essential data products are moved, while redundant or unnecessary files are left behind. By understanding the current data structure, identifying essential data products, and developing a data transfer strategy, researchers can ensure that their data is transferred efficiently and effectively.
