The storage subsystem currently uses a number of hypervisor APIs for transferring files between data stores (both primary and secondary). However, while implementing the storage subsystem API as a storage provider, we have discovered that there is a need for a generic copy method that can copy files between (almost) any source and destination. For example, if we need to copy a file from our storage to S3 or Swift. It would make more sense for the SSVM to provide a generic method for copying files than for us to implement a copy method for S3, Swift, etc. Additionally, the SSVM already has NFS volumes mounted and has easier access to primary and secondary storage.
I will work on formalizing a full functional spec if needed but wanted to get this up for discussion ASAP. I have created a JIRA ticket: https://issues.apache.org/jira/browse/CLOUDSTACK-4773 Thanks, Chris -- Chris Suich chris.su...@netapp.com<mailto:chris.su...@netapp.com> NetApp Software Engineer Data Center Platforms – Cloud Solutions Citrix, Cisco & Red Hat
