The user feedback from the survey is that VMware storage is still complex, and it takes a lot of hard work to make VMware bulletproof operationally. Users were expressing a need to move to a more VM-centric view of the world. Storage is simple to VMware, but storage arrays make this complex.
The bottom line is that storage sucks on VMware, as the hypervisor introduces another layer into the stack, and the storage provisioning, management, and problem determination become more complex. Currently VM Admins, DBAs, server and storage administration staff need to communicate about storage. In the event of a problem, storage will be assumed to be guilty until proved otherwise.
Wikibon believes that solutions to this problem should focus on the VMware administrators and should provide them with a complete set of tools to manage provisioning and management of VMware storage.
I don't think our marketing people could explain the Tintri story any better than that. ;)
