No. "physical storages" means storage products like EMC VNX, NetApp
Data ONTAP, HPE Lefthand and so on.
Say there is a new service named X to manage them. A user, he/she will
be a new IaaS admin, requests many baremetal servers to Ironic and
some baremetal storages to X. After they are provided, he/she will
start to build a new OpenStack deployment with them. Nova in the new
one will provide VMs on the servers and Cinder will manage logical
volumes on the storages. X doesn't manage each logical volume but
pools, user accounts and network connections of the storages.
Yeah, I personally believe that is the domain of configuration management
systems not OpenStack HTTP API services. What you are describing is not a
multi-tenant HTTP API service, it's an IT/storage admin automation tool.
Incidentally, Ironic isn't multi-tenant either. It lives in the weird land
in OpenStack of being an HTTP API service that isn't meant for "normal
users" so in order to provider a cloud service (BareMetal-as-a-Service),
Ironic *requires* Nova to provide the multi-tenancy aspects of the
"as-a-Service" part of the software.
Hmm... so, if I built a (multi-tenant) baremetal IaaS service like SoftLayer
with OpenStack Newton release, tenant users can deploy an OpenStack
environment with cinder using SDS on it. No physical storages.
I think what you're trying to describe is that you want to build a cloud
reseller platform where the reseller tenants would be able to provision
raw storage for an OpenStack deployment that is then resold to end-users
as a hosted cloud service.
Is that correct?
If so, yeah, there really isn't anything like that in the OpenStack
ecosystem, and frankly, I think it would be a tough sell to have that in
OpenStack because it is so very deployer and vendor-specific.
Essentially you want to allow reseller tenants to make SAN hardware
management calls via an API that is exposed through the normal OpenStack
HTTP APIs. And I don't think that is something that is all that
abstractable :(

Ironic is great, of course, but it ain't a cloud service without help from
Nova.
