Hi all,
I have a question relating to nova-volume, and provisioning block 
devices as storage for VMs. As I understand it from the documentation, 
nova-volume will take a block device with LVM on it, and then become an 
iSCSI target to share the logical volumes to compute nodes. I also 
understand that there is another process for using an HP lefthand SAN or 
solaris iSCSI setup, whereby nova-volume can interact with APIs for 
volume creation on the SAN itself.

I have a dell iSCSI SAN, and I can see that I'd be able to mount a LUN 
from the SAN on my nova-volume node, then go through the documented 
process of creating an LVM on this LUN and having nova-volume re-share 
it over iSCSI to the compute nodes, but what I'm wondering is whether I 
can have the compute nodes simple connect to the iSCSI SAN to access 
these volumes (which would be created and managed by nova-volume still), 
rather than connect each compute node to the iSCSI target which 
nova-volume presents? I imagine with this setup, I could take advantage 
of the SAN's HA and performance benefits.

Hope that makes sense..
