[gpfsug-discuss] Alternative to Scale S3 API.

[Andi Christiansen]

Hi Nishaan,

Thanks for you reply.

When you say 5.1? is that 5.1.x.x or 5.0.5.1?

Some of the limitations we have encountered is the multipart upload not being supported and some md5sum that the s3 api does that veeam actually dont like. also interms of the management on the Scale GUI, that has to be on one of the S3 CES nodes in order to be able to show project, container etc... but when you have a HAProxy for enabling SSL then a GUI is not available as they both use port 443? 


i know min.io is not the full stack of S3 API commands but as far as i can read it comes with more features out of the box than Scale S3 does, multipart for an example...

I looked through your documentation and its very close to what we have set up today and found to not work... 

If multipart uploads would be supported today on scale S3 i would think about still using scale for the s3 part but as i expect that you talk about 5.1.x.x i dont see that being released any time soon? and dont know if that is actually going to be supported in that release then i cant wait for that to happen..

Best Regards
Andi Christiansen

I've also ran a few application tools to test for an S3 compliant object stores and again had no issues.
