Sorry if I confused you. I meant Hitachi always says that HCP is not 100% S3 compatible instead of some other vendors.
I never found out, which S3 commands are not supported by HCP.
So I was hoping that there is a list of supported (and unsupported) commands. Or at least a document why Hitachi is so conservative to say "we do not support S3 up to 100%".
If any of our customers asks if the Object Storage supports S3 I repeat the same words:
"Hitachi does not support S3 up to 100%."
Next question is always which commands HCP does not support and I can not give a clear answer.
