[Openstack-operators] Using a SAN for nova-volume & KVM

Hopefully someone has a better answer for you as I'm still relatively
new to OpenStack myself, but I looked into this a little while ago
because I too have an Equalogic SAN and KVM hypervisors. The
Equalogic connector in that equation is provided by XenServer not
OpenStack (in fact I think but am less sure that it isn't even part of
the opensource xen).
Since I'm running a research system I can take some risks and have
decided to go this Ceph for my storage needs, if I were in your HA
needing shoes I'd look at how much coding was required to hook
Equalogic's API (which exists but I haven't looked at in years) into
the nova-volume service, you could be someone's hero, but I don't
think there's any current work toward this.
I'd be happy to be told I'm wrong about that...
