Configure multiple permanent Storages (nearline)

[zea...@gmail.com]

Is it possible to configure multiple permanent storages, which are filled one after one automatically?

In dcm4chee 2.x, multiple nearline storage file systems can be configured. But as I know, only one nearline mount point can be configured as a destination filesystem in FileCopy service to copy files received in online storage to nearline filesystem and the user has to manually switch to next nearline filesystem once it is filled.

In dcm4chee 5.x, you may configure multiple Object Storage ID(s) of Archive Network AE and specify a Storage Threshold for each referred Storage. If you want to fill Storage Systems sequential one by one, keep Object Storage Count = 1. The Storage which Storage ID comes first in literal order will be filled first. So you may choose a naming pattern like fs001, fs002, fs003, ....

Thank you for your answer.

Our structure would look like this:

One online storage --> Cache

Several nearline storages --> Permanent 

How can we make sure that the data is on one of the nearline storages and then delete it from the cache (online) storage?

We have configured multiple  storages an Exporter Rule (Copy To Nearline Storage) and a Queue an Exporter Descriptor (CopyToNearlineStorage), which works fine if there is only one nearline to copy on and then delete it from the Online Storage.

 If I change the configuration now (ObjectStorageID_ArchiveNetworkAE.PNG) , and  configure Storage Threshold for each referred Storage, how can the chache storage (online) be sure that the data is on the permanent storages?

Thanks Gunter. Good to know.
