Hi Stackers,
In TripleO, Ironic provides physical servers for an OpenStack
deployment but we have to configure physical storages manually, or
with any tool, if required. It's better that an OpenStack service
manages physical storages as same as Ironic for servers.
IMO, there are 2 plans to manage physical storages:
When you say "manage physical storage" are you referring to configuring
something like Ceph or GlusterFS or even NFS on a bunch of baremetal
servers?
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.
Ironic is great, of course, but it ain't a cloud service without help
from Nova.
Best,
-jay
