LUMI-O Object Storage

Presenter: Kurt Lust (LUST)

LUMI also has an object storage system. It is useful as a staging location to transfer data to LUMI, but some programs may also benefit from accessing the object storage directly. We highlight the differences between a parallel filesystem such as Lustre and object storage, and discuss how LuMI-O can be accessed.

Q&A

1. Is there a REST API for accessing LUMI-O?

   • Yes, you can use RAW HTTP calls. But this is not recommended, why do you want to do this?

   We want to automate data transfer and make it available for proccesing

   • In that case we would recommend using libraries that support object storage. For example, Python has great support for object storage for example.
