Correct Configuration for ONLINE vs NEARLINE

[toufic...@gmail.com]

Kindly provide the correct configuration for this workflow:

1. Study Ingestion and Storage:

   • All newly received studies should be stored simultaneously on:

     • Local storage (fs1)

     • Amazon S3 (long-term archive)

2. Automated Deletion from Local Storage:

   • After 90 days, studies should be automatically deleted from fs1.

   • The original copies in S3 must be retained and not deleted.

3. On-Demand Access from S3:

   • Even after deletion from fs1, all studies must remain accessible via WADO-RS and C-FIND/C-MOVE (Query/Retrieve).

   • When accessed, dcm4chee should dynamically retrieve the study from S3.

4. Smart Prefetching Based on Incoming Studies:

   • When a new study is received, the system should automatically prefetch all prior studies:

     • Belonging to the same Patient ID

     • And with the same Modality

   • These prefetched studies should be copied from S3 to fs1 to enable faster access

Hi,

Can you please share the correct configuration for the above, if you have already?

I have configured ONLINE and NEARLINE storage and created an export rule for copying studies to NEARLINE once received in ONLINE with a minute delay. Now studies are copied into NEARLINE and are deleted from ONLINE immediately.

I need the configuration for the below:

i) All newly received studies should be stored simultaneously on: ONLINE and NEARLINE storage.

ii) After 5 weeks, studies should be automatically deleted from ONLINE. The original copies in NEARLINE must be retained and should not be deleted.

iii) When accessing the NEARLINE studies, they should be copied from NEARLINE to ONLINE to enable faster access.

Thanks and regards,

Asgar Hussain.B
