   Enable certificate verification | When this option is selected, the client will verify the server certificate.
   Enable KMS encryption | When Enable HTTPS and Enable KMS encryption are selected, KMS encryption will be implemented for all objects uploaded to OBS.

   Multipart Upload, Part Size (MB)

   Objects whose size is larger than the specified part size (5 MB by default) are segmented and uploaded at the OBS background. The size of each part can be set in this dialog box. The value of Part Size (MB) can range from 5 MB to 5 GB.

   NOTE:

   Multipart upload is used by default. Recommended settings of Part Size (MB) are as follows:

   To maximize client performance, set Part Size (MB) based on the upload speed. You are advised to set the Part Size (MB) value larger than the maximum upload speed. For example, if the maximum upload speed is 10 MB/s, set Part Size (MB) to an integer greater than 10 MB. It is recommended that the part size be set to a value two to three times the maximum upload speed.
