We just completed our basic testing today, using web services to call the WFA jobs from Dynamic Ops. The customer selects their needs from a web portal, it is passed over to DO, they process the variables, and call our WFA job.
This is a simple create a volume, add it to a vfiler, export it - all for Linux. We have yet to test the version with SnapMirror, I hope we are ready to test that on Jan. 2.
I am actually working on a project right now to integrate WFA with vCenter Orchestrator and ultimately with vCloud Automation Center. We are still early in the stages though I do have vCO calling WFA to execute workflows. Full integration with vCAC and WFA is on that roadmap. Once we are complete, I will be publishing a joint TR with VMware on this solution. Ping me offline if you would like more information on this joint solution.
