Hello,
I'm interested in this too, but it's really hard to find information on the subject and the one found is confusing . So hereafter my interpretation of the findings I have made:
I think that there is a confusion about the "external virtual storage arrays" mentionned and "external storage". The first definition on the VMware site refers to "Storage provided from an EC2 based virtual storage array to a VMware Cloud on AWS guest OS is ideal for a variety of use cases including; test and development, elasticity for big data workloads and user/home directories. Both block and file protocols are supported. Note that access to external storage is only available from the VMware Cloud on AWS guest operating system. VMware Cloud on AWS cluster datastore access to external storage is not supported."
The second definition is refering to "External storage can only be added through the Managed Service Provider(MSP). Both the SDDC and the external storage are managed by the Managed Service Provider(MSP). Three NFS datastores are attached to an SDDC. The size of the datastores depends on the Managed Service Provider (MSP) offering. Check with the Managed Service Provider (MSP)." the only MSP being Faction (to my knowledge).
I would love to see my Snapmirrored NFS on-prem volumes to VCO and be able to mount them as VMware Cloud datastores in order to be able to register/run the VM's in the Cloud. But this doesn't seem to be possible as the data from such a volume (VCO) would only be accessible from inside a VM (guest OS) running in the VMware Cloud environment.
As said before this is my understanding and I would love to be corrected... and wrong 🙂
Kind regards,
Jan
