Multipart upload/download configuration

If you need to upload and download large objects (typically larger than 5GB) you need to configure so-called multipart uploads/downloads. In this process, a large object is divided into multiple parts, which are then uploaded or downloaded separately. This functionality can also optimize the data throughput. On the storage system, the object is represented as a single entity once the process is complete.

Then click on the bookmark 1. General. Then tick the box 2. Enable multipart uploads and define the part size for upload. Then tick the box 3. Enable multipart downloads and define the part size for download. In the end, click on the button 4. Save changes.
